INSIDE THIS ISSUE SOUTHWIRE REEL MANTRA: RIP IT GOOD . .86

When U.K.-based Bridon set out to expand its capacity to produce the world’s largest and most complex ropes in package weights of up to 650 metric tons, it turned out that it would require the largest rope machine ever made. Above, the capstan for the company’s new system, supplied by Germany’s SKET GmbH, is carefully maneuvered into Bridon’s Neptune Quay facility.

Southwire went to the wayback machine to resurrect an iconic song by DEVO, a 1980s band, to introduce the company’s SIMpull Rip CHIP™ disc for easy removal of stretch wrap on a reel. The result? The DEVO’s classic “Whip it” song has become “Rip it.” Sung by the original band members, the Southwire-produced song offers a unique tone for new product promotions.

Is the wire and cable industry your community?

Publisher | Steven J. Fetteroll

Every time I visit a plant, I am reminded of just how remarkable a profession the wire and cable sector is, and a recent trip I took placed an exclamation point on the truth of that statement. A few key staffers of the company—which has grown steadily despite the recent economic downturn—pointed out with pride the investments they have made both in technology and in employee training. They recognize that both those elements are needed to be successful. The results could be seen on the shop floor, where all the pieces of the production process flawlessly meshed.

Being in the wire and cable business defines us and we should celebrate it because what we do keeps the world working. Power and data transmission, energy exploration, military systems, automobiles, airplanes and the hundreds of millions of smart phones and portable music players and much, much more just don’t happen without wire and cable.

Interestingly, this same successful company has a large number of WAI members because membership is viewed as an investment in human resources. While I am not claiming a direct correlation between WAI membership and success, I would suggest that employees who are part of a strong professional network are drivers of innovation and are better poised to manage challenges.

Capital investment in manufacturing is significant for obvious reasons. However, it’s not simple, especially in uneasy economic times, for some companies to make training and development a high priority. But if you consider that the ultimate goal—to be successful—requires both technology and a well-rounded workforce, a call here is warranted for a commitment to the body that represents the industry. Employees charged with managing the next critical capital project or re-engineering a production cell should be given all the available tools. WAI is an important resource as we are a unique provider of information and education as well as a network for the combined industry. We are the community that connects the collective experiences of hundreds of different wire and cable manufacturing operations.

In May, the WAI Board of Directors placed a renewed emphasis on membership with the understanding that it needs to better reflect the diversity and depth of the industry. The Member Relations Committee has launched a coordinated effort to encourage membership and the early response has been exceptional (see pp. 30-31). For those of you who are not members, I encourage you to revisit the issue. This is a terrific time to become involved and invest in yourself.

INDUSTRY NEWS

INDUSTRY NEWS Bridon installs world’s largest rope machine at its Neptune Quay plant U.K.-based Bridon has expanded its capacity in a big, big way, installing the largest machine ever made for producing steel wire ropes. Scheduled for a November launch, the system will be able to manufacture the world’s largest and most complex ropes in package weights of up to 650 metric tons.

A Bridon employee is dwarfed by the capstan of the company’s new record-sized machine, supplied by Germany’s SKET GmbH. A press release said that it ordered the 10 million euro system from Germany’s SKET GmbH “to meet demand for the offshore sector in particular due to the increasingly challenging applications the industry requires.” The closer, an eight-basket section that was to be the first element installed at the Neptune Quay plant, “will allow the company to produce far more complex ropes than had ever previously been possible with such weights,” it said. The machine, it said, will allow Bridon to make offshore ropes that are specifical-

ly engineered to deal with the challenges of deepwater deployment under tough environmental conditions.

In the release, Bridon cited the need “to keep pace with the ambitions of the oil and gas industry as a principal motivation for the Neptune Quay site’s construction.” While the historical challenge of deep-water deployment has been to deploy 300 metric tons in 3000 meters of water, the industry is increasingly demanding lifting systems that can deploy weights “significantly in excess of 300 metric tons and as great as 600 metric tons, at depths of up to 4000 meters, requiring multistrand ropes that boast massive breaking loads, optimized bend fatigue performance, effective lubrication, and minimal rotation under load.”

In addition to the new closer, the facility also got a new stranding machine, also from SKET, that winds dozens of wires together into individual strands that can be spun together by the closer machine, the release said. It added that the logistics for the project required a lot of planning.

“To ease the load out of 650 metric-ton rope reels onto vessels moored at the factory’s deepwater quayside, Bridon has commissioned Newcastle-based engineering firm Pipe Coil Technology to deliver an innovative take-up stand; a machine which is used to move new ropes on the final reels from the closer to the Quay side without any assistance.

This enables a variety of methods to get reels of all sizes onto vessels moored alongside the plant.”

Observed Bridon Group Chief Executive Jon Templeman, “In constructing a state of the art factory that will lead the world in the production of large, complex ropes, we knew we could settle for nothing less than the biggest and best rope-making machinery ever produced. The closer, strander, and take-up stand at Bridon Neptune Quay are not only the largest rope making machines in existence; they also have the capacity to make the most complex and highly engineered ropes ever conceived. Close collaboration with our customers has developed our understanding of the complex tasks they face in the world’s toughest environments.

Thanks to this collaborative approach, and to the ingenuity of our key suppliers, SKET and Pipe Coil Technology, this machinery will surpass all previous rope-making equipment in manufacturing ropes tailored to 21st century offshore challenges.”

Holland Wire plant to be consolidated The Michigan plant of Holland Wire Products, Inc., will be consolidated into the operations of its parent company, Hickory Springs Manufacturing Co. A story in the Holland Sentinel by Stephen Kloosterman cited Bobby Bush, a company spokesman, as saying that the closing will result in the loss of some 40 jobs in the Holland plant.

Sevkabel Group supplies cables related to 2014 winter Olympics Russia’s Sevkabel Group has provided nearly 400 km of power cable to increase electrical capacity to the mountain resort of Krasnaya Polyana and the ski resort complexes in Rosa-Hutor and the Imeretinskaya Valley, which are venues for the 2014 Winter Olympics to be based in Sochi, Russia.

A press release from Dow Electrical & Telecommunications (Dow E&T), which is providing the company’s DOW ENDURANCE™ family of insulation and semiconductive materials to Sevkabel, said that the project includes

plant near Hickory Spring’s headquarters in North Carolina, it noted.

In the report, Bush said that orders had dropped, and that shipping costs made the Holland plant expensive to operate, as Holland Wire Products used wire sent from North Carolina to make bed springs, which were then shipped back to North Carolina. “We didn’t need two plants running at under-capacity,” he said.

A few employees have indicated they were interested in the offer, said the report, which noted that the equipment from the Holland plant will be moved to North Carolina within six months. Founded in the 1960s, Holland Wire was bought by Hickory Springs in 1988.

Cables from Russia’s Sevkabel Group will be used for new sites being built to host the 2014 Winter Olympics. both medium- voltage and high-voltage cables. The cables made by Sevkabel, a Dow Inside licensee, will be installed underground to manage long-term reliability issues, some of which are associated with the extreme weather and terrain conditions in the region, it said.

The MV and HV cables range from 6 kV to 220 kV, all manufactured to meet stringent industry standards using

DOW ENDURANCE materials, the release said.

Installation, it noted, has already been completed for 54 km of 110 kV HV cable and 340 km of 10 kV MV cable.

“Increasingly, underground power cables are being recognized for technical advantages and consistent performance,” said Filip Tauson, Commercial Director Europe/Middle East/Africa, Dow E&T. “In addition to the obvious benefits for power losses associated with challenging terrain and weather, underground systems offer improved economics over the life of the system with lower short- and long-term maintenance costs with a life expectancy of more than 40 years.”

“The combination of our manufacturing expertise and quality products, combined with Dow E&T’s technology leadership and commitment to innovation will enable us to deliver the long-life, reliable cables that our industry demands,” said Sevkabel Group Director General Vladimir Bukhin.

LS Cable & System reports winning major power cable order from Kuwait South Korea’s LS Cable & System announced that it has won a cable project worth $110 million, the second such contract it has received from the Ministry of Electricity and Water of Kuwait.

A press release said that LS Cable & System will supply and install 400 kV extra-high voltage conductor with insulated cables and connectors on a turnkey basis. Kuwait, it said, is currently building a new town on its border with Saudi Arabia named Sabah Al Ahmad. Last spring, the ministry awarded LS Cable a similar contract worth $107 million, it said.

“Unlike ordinary extra-high voltage cable using pure copper for the conductor, the conductor with insulated cables to be installed at Sabah Al Ahmad will be a high-tech cable in which the strands of wire comprising the conductors are coated with enamel to reduce transmission resistance,” the release said. “This raises transmission capacity by more than 20%. If this type of conductor with insulated cable is used, the overall weight and thickness of the cable can be reduced as much as the transmission resistance drops, greatly reducing the cost of cable manufacturing and power grid implementation. This product is a typical high-value-added cable that requires precision and sophisticated skills not just for development, but also for production.”

The release provided the following technical details: “As power cables carrying electricity develop resistance at their center due to the magnetic properties of the conductor, the electric current concentrates mostly along the outer surface (the “skin”) of the conductor. Due to this “skin effect” about 25 to 45% resistance will be generated, and limit the transmitted electric current after all. However, a conductor with properly insulated cable will only have about 5% resistance thus raising transmission capacity by at least 20% as compared to conventional products. As a conductor with insulated cable consists of strands of conductor wires with an

enamel coating instead of solid copper wires, the technology for keeping each strand electrically insulated is needed.

This is what makes such a cable a state-of-the-art cable product. Conductor with insulated cables require the highest design capabilities with regard to the arrangement of the enamel-coated strands and ordinary strands, segment configuration according to the type of conductor, and compressibility of the conductor.”

An unidentified spokesman was cited as saying that LS Cable has become a notable global supplier of EHV cables, which are vital for construction new power grids, and that the company “will try and win contracts throughout the Middle East market where large infrastructure projects are expected to be built soon.”

Joint venture inaugurates a new U.S. copper wire rod plant in Indiana On July 10, SDI La Farga LLC, a US$39 million joint venture of U.S.-based Steel Dynamics Inc. (SDI) and Spain’s La Farga Group, held a grand opening celebration of its new copper wire rod plant in New Haven, Indiana, which has fired up its furnace and melted its first load of copper scrap.

A press release said that the venture, which will produce 8 mm copper rod, will employ some three dozen employees by 2013. It noted that SDI, which has exported a large portion of its copper scrap to China, will be a significant scrap supplier for the venture. Using advanced refining technology, the company will provide high purity copper rod at competitive prices while reducing carbon output, it said.

An article in Recycling Today said that the 85,000-sq-ft operation will run on a 24-hour cycle, with eight hours required to melt a full furnace charge, eight hours needed to prepare the molten copper for casting and eight hours required for casting. The mill’s primary line produces 8-mm rod while a secondary breakdown mill can make thinner gauge wire, it said. It noted that the plant is based on La Farga LaCambra’s operations in Barcelona, though the (continued on page 15)

SpringWorld to return to Rosemont Convention Center this October A myriad of challenges face spring manufacturers, which organizers of SpringWorld® 2012 insist makes it essential for anyone in the industry to attend this event, to be held Oct. 3-5, 2012, at the Donald E. Stephens Convention Center in Rosemont, Illinois, USA.

SpringWorld® 2012 will showcase both spring and wireforming techology.

“In this fiercely competitive marketplace, with spring manufacturers facing all sorts of economic pressures and business challenges, spring manufacturing executives should be attending this year’s SpringWorld,” said Rick Ross, president of the Chicago Association of Spring Manufacturers, Inc. (CASMI). “It is the perfect time to do some strategic planning, to step back and analyze your customers’ future needs, and figure out what equipment will best serve those needs. Spring World gives you a chance to see all this machinery in one place, and allows you to kick some tires to find out what will work best for your customers.”

A CASMI press release said that there is a sense that the outlook for the spring industry is positive and upbeat.

“Two months prior to the show opening, the exhibitor base is optimistic, with a 96% sellout of planned floor space,” it said, noting that the show will offer new equipment options, methods to retool equipment and reorganize the shop floor. A strong attendee showing is also expected as registration has been ahead of the pace for the 2010 event, which had some 2,700 attendees, it said, suggesting that this means that the economy is again gaining steam.

“We expect a strong attendance again this year as Rosemont is the place to see all the equipment available to the spring industry in one place” said CASMI Executive Director and Show Manager Tom Renk “If you are in the spring industry, you should be at SpringWorld 2012 to see the equipment, to meet with your peers and monitor what your competitors are doing. This is our own industry show and we need to support it to help make the industry even stronger.”

SpringWorld also includes wire-forming equipment,

Noranda Aluminum plans to build a new rod mill at yet to be chosen site U.S.-based Noranda Aluminum Holding Corporation announced plans to invest $45 million investment to build a new rod mill in the U.S., the exact location yet to be determined.

A press release said that rod mill project includes infrastructure development and construction of a new, state-ofthe-art mill to produce redraw rod, which is used in the manufacture of electrical wire and various types of cable, as well as for deoxidizing steel. The company expects spending on the project to begin in 2013, and expects full production to be realized in 2015, it said. â&#x20AC;&#x153;Redraw rod has been one of our strongest primary aluminum products in recent periods, and we expect continued growth in this product,â&#x20AC;? said Noranda President and CEO Layle K. (Kip) Smith.

At its website, Noranda notes that its smelter produced approximately 13% of total primary aluminum production in the U.S. during 2011. Its focus is aluminum foil and light gauge sheets, but it also produces rod.

furnace is more than 50% larger than the original furnace in Spain.

The mill is the first in the U.S. using advanced and patented technology for refining copper to achieve the ASTM B-49 standard, the release said. A key to the process is the 250-plus-ton capacity refining furnace supplied by Italyâ&#x20AC;&#x2122;s Continuus-Properzi, which supplied the casting and rolling line and ancillary equipment. The newly designed furnace charges the scrap from the top of the furnace rather than the traditional practice of using lateral doors, making it easier to load large quantities of scrap each loading cycle through the charging door positioned on top of the furnace, it said.

Explained a Properzi spokesperson, â&#x20AC;&#x153;Basically it is a tiltable/reverberatory/refining furnace improved by a patented (Properzi) charging door geometry allowing the feeding of the scrap from the top by means of a belt type conveyor arranged by the buyers. The casting and rolling line and its ancillaries are entirely supplied by (us), with a 30 ton/hour rate of 8 mm copper rod or better FRHC rod meaning Fire Refined High Conductivity rod. The casting (wheel), three meters in diameter, is followed by five break-down cantilevered rolling passes and one finishing monoblock with eight stands (using) a typical Properzi configuration. Coils of 3.8-5.0 ton are automatically discharged and packed. The technology and know-how for making rod from scrap is from La Farga, an important shareholder in the project.â&#x20AC;?

The Prysmian Group has been awarded a contract from Telecom Argentina to supply and install an optical network that will provide the passive infrastructure for the first part of the country’s new FTTH network.

A press release said that the contract will involve building a network that will serve 4000 homes, with projected initial take-up/connection rate of just under 40%. The Prysmian Group will work with Valtellina Sud América S.A., a contractor that will handle the system installation activities.

“Work will start immediately and will continue over a two year period, during which time Telecom Argentina will continue to formulate the next stages of their broadband roll-out,” it said. The contract includes Prysmian’s in-house produced optical fiber, both standard G652 and BendBright G657, bend insensitive technologies, together with a wide range of passive connectivity components in order to provide the full end-to-end passive network, it said.

“This is a highly significant project for both Telecom Argentina and Prysmian Group,” said Gustavo Etchepare, CEO of Prysmian Group in Argentina.

“Consumer demand for greater bandwidth continues to grow and the only true future proof way of keeping pace with this demand is to install optical fiber closer and closer to the final customer. Telecom Argentina recognizes this and we are both delighted to be working with them on this project and determined to provide them with the system they need to meet their customer needs both now and well into the future.”

The release explained that Telecom Argentina is expanding its broadband services by deploying a FTTH network, using GPON technology, that addresses three discreet urban scenarios: the closed (condominium) environment, individual new buildings (MDU), both of which are considered “greenfield” and open-neighborhood configuration. The initial project, it said, is the first stage in Telecom Argentina’s master plan to roll out highspeed broadband, focused mainly on the city of Buenos Aires, across all three infrastructure scenarios, in response to growing consumer demand for faster broadband services.

Telecom Argentina selected Prysmian Group as their preferred contractor in an open tender process which attracted interest from system suppliers around the world, the release said. “With numerous production facilities worldwide Prysmian is very much a local company in Argentina, having a major copper telecom cable production facility in the plant of La Rosa.”

O.M. Lesmo’s 50-year anniversary: a legacy for company and customers Earlier this year, Italy’s O.M. Lesmo met with wire and cable industry customers at wire Düsseldorf, with Commercial Director Giovanni Cecchini-Manara welcoming them at a celebration of the rotating equipment supplier’s 50th anniversary.

“To be here today makes me very proud,” said Cecchini-Manara, observing that achieving 50 years was only possible because of “the efforts of so many good people before us.” Those efforts, he declared, came from not just staff, but from the very good partnerships and support that “you, our clients and partners, have generously extended to us in so many ways along the years.”

Those fundamentals, he said, are what makes the company’s continued presence possible. “Let me thank in particular all those clients who have repeatedly put their trust in our equipment, installing in their factories many machines along the years.”

North America, “where we have established our second home”; in Europe, “our first home, where we have served the German-speaking customers from our base in Stuttgart, and where in the Nordic Countries we have so many friends who have repeatedly given us their trust.”

Success, never a given, was hard-earned and painful, said Cecchini-Manara, noting that recent years have seen machinery producers disappear or be taken over by bigger firms. Despite harsh economic times, O.M. Lesmo chose not to cut expenses by offshoring some of its Italian manufacturing to the east, he said. “It has been a decision

The Golden Jubiliee also honored the most veteran company employee.

See p. 20.

The company’s technology has been deployed around the world, Cecchini-Manara said. Success stories include South America, “where we have so many good friends and we are historically a very well accepted brand”; in Southeast Asia, “where for so many years we have had friends who not only purchased from us, but who also stimulated us to improve”; in the Middle East and Africa, “where we have been pushed to provide equipment with always higher specifications at a more reasonable price”; in Russia and the neighboring countries, “where we pride ourselves by blending in the local culture and habits”; in

It has been hard at times, we have felt alone in this at other times. But eventually it has proven a good decision, and we are proud of it. If we are here today, it is because so many colleagues have made it possible, with hard work and excellent ideas.

“It is therefore with a lot of enthusiasm that today we celebrate our golden jubilee,” said Cecchini-Manara. “It is not only an anniversary, it is a remarkable achievement that we have the duty to honor.” For more comments, see pp. 62-63.

ASIAN FOCUS

ASIAN FOCUS India: a land of incredible potential, but one in need of more reliable power India recently made headlines for massive power outages that saw power lost on consecutive days for as many as 300 million people in northern India. “Infrastructure India: A Long Road Ahead,” an article by Charles Runckel, Runckel Associates (Internet www.business-in-asia.com), looks both at India’s potential for business, including power concerns as well as other aspects. Below are updated excerpts from Runckel, whose company provides the full spectrum of international business consulting services for clients interested in doing business in Asia.

China and India often are compared in the same breath by western executives weighing sites for expansion or outsourcing, but the reality of the situation is that in terms of infrastructure, China is decades ahead of India, an important consideration for industries reliant on strong power, water, transport or information infrastructure.

Like China, India is a large country and some sections are far more developed than others, so major destinations like Bangalore or Delhi need to be considered separately from some remote province in central India. Also as in China, the

A not unusual sight in India: a labyrinth of cables. massive population moving from very poor to somewhat poor is resulting in titanic shifts in demand for commodities vital to businesses, swamping the electrical grid and threatening the vital supply of fresh water. Whether your business makes high-tech gadgets or bathroom slippers, infrastructure matters and a long-term consideration of what to expect is the first step in any outsourcing plan. While the list of problems is extensive, however, an investor should keep in mind that India has just as many advantages. There is no such thing as a free lunch, and businesses should be aware

of both the advantages and pitfalls of investing in India.

India’s overstressed power grid is one of the most obvious signs of lagging infrastructure development. In India, power failures can and should be expected daily, even in the most developed areas of Delhi, Mumbai and Bangalore. Any respectable business or factory in India maintains a diesel generator, and the shopping malls and call centers are built atop huge storage tanks of fuel. The outages aren’t just spikes, but rather hour-long blackouts with multi-hour brownouts thrown in. Beyond keeping industrial machines and computers running, air conditioning is essential to office work in this unmercifully hot country, and even service providers must bear the burden of backup power.

In a good hotel, visitors may not even notice the shift from grid to generator, but this necessity adds to the cost of building and operating a facility in India. Effectively, the government is passing the buck on infrastructure to the investor, and generator costs add up fast. Some industrial parks or research parks will provide continuous power through shared generators.

Is the situation going to improve? India’s government has committed itself to improving the nation’s power grid, but in the world’s largest democracy, government targets tend towards “Electricity for all by 2012” (a part of many politicians’ election campaigns) rather than “Reliable power by 2012” or “A well-managed grid by 2012.”

India’s airports are unfortunately the first thing a traveler sees, and they are undergoing much needed improvements.

To take Delhi’s Indira Gandhi airport as an example, the airport currently is built to accommodate 12.5 million passengers a year but must deal with 16.2 million (for comparison, Thailand’s Suvarnabhumi airport is built to handle 45 million). The aesthetics of the structure aside (which are poor, with claustrophobically low ceilings in places), the check-in area actually leaks when it rains. A third terminal is being built, however, with 35 million passengers a year capacity and the modern features that international travelers have come to expect. This pattern is true across India, where currently the air facilities are sorely in need of replacement (upgrades to most would not be worthwhile), but also where those replacements are being built and at a frenzied pace.

At India’s ports the dual problems are a lack of infrastructure and a crippling bureaucracy. This differs greatly from port to port, but in general the necessary upgrades are being made, but very slowly. The inefficiency issue is harder to fix, and is a reflection of India’s bloated public sector. The often-quoted statistic is that Shanghai’s port can turnaround a container ship in eight hours, but the same ship in Bombay takes three days. Without a doubt, China or Thailand’s ports are well ahead of India’s, though again this is a matter of efficiency (and delays) and not outright capability (India can still deal with container ships, just not

ASIAN NEWS BRIEFS Ultra-high-voltage power transmission project is planned for China’s Zhejiang Province Construction on a west-to-east ultra-high-voltage direct current power transmission project was slated to have begun in East China’s Zhejiang Province as part of efforts to ease power shortages in its eastern regions.

China Daily reports that the project, funded by the State Grid Corporation of China, will transport about 40 billion kilowatt-hours of electricity annually from the Xiluodu Hydropower Station in Southwest China to Zhejiang after its scheduled completion in 2014. It noted that the change will annually save 12.28 million metric tons of standard coal, cutting 34 million tons of carbon emissions.

The SGCC, the nation's major power grid operator, will invest US$3.79 billion) in the project, the report said. It will start in Yibin, a southern city in Sichuan Province, and deploy a 1,680 km transmission line that will traverse the Guizhou, Jiangxi and Hunan provinces to reach Zhejiang’s central city of Jinhua. SGCC Vice-President Shu Yinbiao said in the article that compared to previous projects, the line will be built with a greater transmission capacity, more advanced technology and a higher domestic manufacturing level. It noted that China has made further use of ultra-high voltage direct current power transmission projects to meet demand from economicallydeveloped eastern cities affected by power shortages.

Eurofer claims that India is dumping steel wire The European Commission said it had received an antidumping complaint by European steel producers' group Eurofer against imports of stainless steel wires from India.

Reuters reports that the complaint claims that producers of certain types of steel wire have benefited from a number of subsidies granted by India, and are selling their wire in the European Union (EU) at below-market prices, hurting European competitors. It reported that the Commission would investigate whether or not the steel wire is being unfairly subsidized and has invited the Indian government for consultations on the matter.

The article said that India and the EU have been negotiating a free trade agreement since 2007, but talks stalled this year over differences in duties on cars and market access for software and service companies. The EU, India’s biggest trading partner, bought more than US$49.26 billion worth of Indian goods and services in 2010, the article said, noting that the sum represents 2.4 percent of the EU total.

India has also encountered problems with the EU over a law requiring all airlines flying in and out of Europe to pay for their carbon emissions, the article said. It noted that India has said it will not comply with the law, but there are other aspects that may make that stand difficult to maintain.

quickly) so this is a factor to necessarily add into time calculations, and additional costs of shipping should be considered when weighing manufacturing costs between India and other Asian countries.

India’s rural population continues to flow towards the urban centers for work and skilled labor (including Chris Runckel knowledge workers) is moving from the second-tier cities to the main hubs of Delhi, Calcutta, Bangalore and Mumbai. The national government is trying to redirect migrants to the second tier cities to prevent slums from forming, and knowledge industries are increasingly looking at second tier cities as salaries in the major cities, especially Bangalore, skyrocket. A recent college graduate can expect to make $300 a month in Delhi, over $500 in Bangalore and $150-$250 in a second tier city.

Unskilled, and even skilled, labor is abundant and the shortages seen in Eastern China and Southern Vietnam are not an issue. Workers are often satisfied with a lower standard of dorm or hostel (if any) than those in East Asia, who have come to expect sprawling dorm towns with limited, but still present amenities. In India, such housing and other issues tend to take care of themselves, however the result of this is that transport systems are not as organized as in China or Vietnam, so like much else in India decreased efficiency is traded for low cost.

The choice of which city in India to go to depends on what incentives are offered by the city in question and how its infrastructure matches a company’s needs.

India’s infrastructure presents a bleak image, but most of the problems are surmountable with adequate planning and investment. For some industries, the problems are just too numerous and the lack of infrastructure drives investors to China and Vietnam, despite rising labor costs, worker shortages and declining government incentives. For others, India’s rock bottom wages and English-speaking workforce trump the infrastructure headaches. It is essential to plan for and budget the additional costs involved (such as a generator) from the beginning, or else India becomes a quagmire requiring ever more investment. If proper precautions are taken, however, India holds as much potential as China did 10 years ago and the current lack of infrastructure should be seen as just another hurdle to overcome in outsourcing.

Jason Black, a research leader in grid systems with Battelle’s Energy, Environment and Material Sciences Global Business, recently said in an interview that India’s power grid is reasonably good for transmission but has problems with distribution side, a situation made worse as often the demands as its current generation mix often can't meet the demands of the population. As a result. rolling blackouts happen on a regular basis in many parts of the country.

Stanley Black & Decker reports agreement to acquire Infastech U.S.-based Stanley Black & Decker (SB&D) announced that it has agreed to acquire Infastech, a global manufacturer of specialty engineered fastening technologies based in Hong Kong, from CVC Capital Partners and Standard Chartered Private Equity Limited, for US$850 million.

The deal, a press release said, expands SB&D’s industrial franchise, engineered fastening platform and footprint in emerging markets; creates a highly complementary fit with existing Emhart Teknologies’ engineered fastening business; and increases the company’s scale, expanding its global presence and opening new end markets for specialty fastening growth. With revenues of about US$500 million and more than 2,000 employees, Infastech is a leading producer of engineered mechanical fasteners and one of the largest Asian-based global players in the specialty mechanical fastener market, it said. Infastech supplies highly engineered fastening technologies and applications for a diverse bluechip customer base in the industrial, electronics, automotive, construction and aerospace end markets. More than half of its 2011 revenues were generated in the Asia-Pacific region and once combined with Emhart, SB&D’s engineered fastening platform, the enlarged business will generate close to 40% of its revenues from this high growth region, it said.

Total company revenues from the emerging markets will increase to about 16%, an important step towards the company's mid-decade goal of 20%, it said Infastech’s product portfolio includes brands such as Avdel®, ELCO® and iFormTM, which collectively are sold to customers in more than 150 countries worldwide, the release said. The combined engineered fastening platform will generate approximately half of its revenues from automotive manufacturing, a third from industrial fastening applications and 20% from high growth verticals such as electronics, it said. “With the acquisition of Infastech, the engineered fastening platform will be the first of the company's recently identified new growth platforms to achieve its mid-decade goal of $1-$2 billion in revenue.”

“Infastech is both a highly accretive acquisition and a perfect strategic fit for Stanley Black and Decker,” said SB&D President and CEO John F. Lundgren. “It adds to our strong positioning in specialty engineered fastening, an industry which has solid growth prospects,” he said.

FIBER WATCH NTT Communications to launch the Asia Submarine-cable Express As of press time, NTT Communications was scheduled to have launched the Asia Submarine-cable Express (ASE), connecting Japan, the Philippines, Singapore and Malaysia, with Hong Kong slated to be added to the network next year.

A report in Global Telecoms Business said that ASE is designed to operate at 40 gigabits a second and can carry data at more than 15 terabits a second. NTT, it said, will integrate the cable into the backbone of its tier-1 global IP network at first, and then its cloud-based network service, Arcstar Universal One. It will also integrate ASE’s routes into its Arcstar global leased line service.

NTT Com, the major investor in the system, partnered Philippine Long Distance Telephone, Telekom Malaysia and Singapore’s StarHub for the project, the report said.

The submarine cable, which is said to offer the lowest latency network service between Tokyo and Singapore, will ultimately offer 100 gigabits/sec technology, it said.

A report said that once the subsea cable is launched, NTT Com will begin offering an enhanced global leased line service, by incorporating ASE’s low-latency routes

28 | WIRE JOURNAL INTERNATIONAL

into its existing Arcstar Global Leased Line Service. The newly enhanced service leverages ASE’s Japan-Singapore connection with more than 65 milliseconds latency, more than 3 milliseconds faster than routes via other subsea cables, it said.

Company plans submarine cable system to connect U.S. and Brazil Seaborn Networks plans to develop a Brazil-U.S. submarine cable link. Described as “an emerging submarine player,” Seaborn Networks previously announced a plan to build Seabras-1, a 32 Tbps submarine cable that would provide what it said would be the first direct route between Sao Paulo and the United States. Set to go live in 2014, the network has already attracted both Tata Communications and Sidera Networks as wholesale customers, it said.

The Seabras project was announced in 2011 by eFive Telecoms (Pty) Ltd., who led the project as principal. In April 2011, the Bank of China announced that it was interested in investing 60% of the funds required for the project. The Industrial Development Corporation of South Africa has also expressed interest in funding.

CHAPTER CORNER

CHAPTER CORNER 4 speakers confirmed for Oct. 11 New England Chapter educational program Experts in Lean, toxic materials, perfluoropolymers and TPUs for wire and cable will be featured at an educational program that the New England Chapter is staging on Oct. 11 at the Holiday Inn Boxborough in Boxborough, Massachusetts. The program will begin at 4 pm with a networking reception, followed by the presentations and then dinner. The presenters include: • Bruce Hamilton, president of GBMP, a Boston-based non-profit provider of lean technology, will explain why it is not unusual for organizations to struggle with their implementation or use of Lean methodology in their operations.

His 30-minute presentation will provide insight to managers seeking greater depth and breadth of Lean deployment that transcends even the most unique business venues. His 2004 video, Toast Kaizen (recipient of 2005 Academic Shingo Prize), has been used world-wide to introduce the basics of lean manufacturing.

• Liz Harriman, deputy director of the Massachusetts Toxics Use Reduction Institute (TURI) at the University of Massachusetts, helps companies identify safer alternatives to toxic chemicals used in manufacturing. She has made presentations at prior New England Chapter educational programs and was part of a federal project that studied Life Cycle Assessments for cables. She plans to discuss new developments in chemical restrictions and policies, such as the EU RoHS and REACH directives, EPA chemical action plans and TURA higher hazard substances.

• Jacob Lahijani is a senior research scientist with DuPont Fluoropolymer Solutions, located in Wilmington, Delaware.

His primary focus is the development of high-performance perfluoropolymer materials for wire and cable and semiconductor applications. During his 30-year career with DuPont, he has served in a number of research positions working in the areas of advanced polymeric materials and fluoropolymer processing. He holds a Ph.D. in chemical engineering from The Pennsylvania State University. He will speak on DuPont’s™ ECCtreme™ ECA perfluoropolymer resin.

• Steven Stoll is a senior technical sales representative for the TPU business of Huntsman Polyurethanes. He holds a degree in biochemistry from Oakland University, and a master's degree from Central Michigan University. He has more than 30 years of experience in the polymer field in a variety of technical and commercial roles, and is the holder of five patents. He will talk about the development and commercialization of a halogen-free flame retardant TPU for the wire and cable market that passes stringent VW-1 flammability testing.

Brian Holden, Carris Reels, Inc., and Roy St. Andre, EIS Wire & Cable, are the co-chairs for the educational event.

Also working on the program is chapter President John Rivers, Delaware Marketing Services. “The goal for this program is to provide information on more than one topic

32 | WIRE JOURNAL INTERNATIONAL

that would be of interest to the wire and cable industry,” said Rivers. “We’ve got good speakers and the 30-minute presentations will be long enough to provide good information yet allow attendees to ask for more details later.”

Ohio Valley Chapter reports the results for its 2012 golf tournament The WAI Ohio Valley Chapter held its 10th annual golf outing at the Grantwood Golf Course in Solon, Ohio, on Aug. 2, with the winning team claiming top honors by shooting a very respectable 10 under par.

A total of 34 golfers played, with the winners being Dave Simpson and Chris Winkel, both of Worldwide Superabrasives, and Vince Griffin and Mike Swift of Premier Wire Die. Griffin, whose team has had much success at past chapter tournaments, said that it proved to be another good day at the Ohio Valley golf outing. He noted that the team was without one of its mainstays.

From l-r, tournament vice chairman Mike Caranna of American Spring Wire with the winning foursome of Mike Swift, Premier Wire Die; Chris Winkel, Worldwide Superabrasives; Vince Griffin, Premier Wire Die; and Dave Simpson, Worldwide Superabrasives Ironically, the missing “mainstay” for the event was none other than the person who has organized it the last three years: Aaron Nolan, Sumitomo Electric Carbide, Inc., who has been a regular on Vince’s team. He did, however, have a pretty good excuse, one that even a passionate golfer would have to accept: his wife Amy had just given birth to their first child, daughter Alexa Marie, on July 28, days before the event. “I hated missing the tournament, but I had to be with Amy,” he said.

Sponsors for the event included Amacoil, $5000 Hole in One; Wire Lab, Closest to Pin; US Synthetic Wire Die, Closest to Pin; Premier Wire Die, Corporate Hole; Enkotec, Corporate Hole; Bekaert Orrville, Corporate Hole; Victor Metal, Corporate Hole; and Worldwide Superabrasives.

Up next will be the New England Chapter’s 18th Annual Golf Tournament, to be held Sept. 10 in Ellington, Connecticut, USA, at the Ellington Ridge Country Club.

For more details on this event, call WAI’s Anna Bzowski at tel. 203-453-2777, ext. 126, or abzowski@wirenet.org.

The New England event will be followed by The Vannais Southeast Chapter 11th Annual Golf Tournament, to be held Oct. 18 in Conover, North Carolina, USA, at the Rock Barn Golf & Spa. The final outing of the year will be the Western Chapter’s 12th Annual “Wild West Shootout” Golf Tournament, to be held Oct. 22, in Rancho Palos Verdes, California, USA, at the Los Verdes Golf Course.

Each event offers a range of sponsorship opportunities for companies that would like to both support the event and get a bit of exposure. For more details on such opportunities, as well as the cost for playing and registration, e-mail WAI’s Steve Fetteroll at sfetteroll@wirenet.org or visit the individual chapter pages at www.wirenet.org.

WAI’s Poland Chapter is holding its ninth technical seminar on Sept. 20-22 at the Antalowka Hotel in Zakopane, Poland.

Organizers of Wire & Cable India, the 4th International Exhibition & Conference for the wire and cable industry, report that they expect to see a strong 2012 staging when the event returns Oct. 30-Nov. 1 to the Bombay Convention & Exhibition Center in Mumbai.

A press release from Messe Düsseldorf, which through its subsidiary Messe Düsseldorf India Pvt. is producing the event with the Confederation of Indian Industry (CII), said the country has many long-term needs that should result in long-term business for the wire and cable industry. The wire industry in India, it said, depends greatly on the construction and automotive sector. The extended global economic crisis has held back growth for the building sector from the projected average of 10% per year to a more modest yet still respectable 7% increase, it noted. “Infrastructure and housing are the growth engines of the construction sector and the government places high priority on transportation networks and residential housing (urban areas alone are in need of millions of apartments).

Equipment W

ire and cable equipment can last for decades, but the industry depends on new and better ways, especially for more demanding products, all of which results in interest in the latest technology. This feature presents a range of equipment, much of it shown at wire Düsseldorf, comments from a few exhibitors and the story of how one U.S. company prepared for the trade show.

AIM Inc. U.S. AIM Inc.’s display at wire Düsseldorf included the AccuForm Modular 3Dx (AFM-3Dx) with integrated indexing tool changer. The modular line consists of components, interchangeable within the same size, that include the turntable, straightener, feeder, three-dimensional bender and optional accessories such as punching, chamfering, threading, drilling, piercing, marking, cold heading, among others. Each wire bending machine can have up to 32 motion axes, depending on the machine configuration.

These machines take wire directly from coil, straighten it, bend it, and cut it to create wire products AIM’s new AFM 3D12-T model designed with the use of AIM’s exclusive software package. SmartEditor® provides flexibility and simplicity in setup. Programming is quick and easy.

All you need is to enter the lengths and angles of your product, view the design, edit if necessary, and begin production. A turret option (-T) can add one servo axis for a automatic and programmable bending tool-changer along with a second bending pin. Each AFM-3Dx machine has a two-plane wire straightener, with each plane having 11 “V” groove roller bearings. Two different diameters of rollers allow straightening of a wider range of wire with just one straightener. Wire range: 2.7 mm to 8 mm, wire

linearity is less than 5:1000 for a 6-mm wire diameter.

For wire diameters under 2.7 mm, an additional straightener is required. The feeder module has four driven rollers, one wire guide, sprocket-belt reduction unit, precision hi-torque drive (HTD) belts and one brushless servomotor. The feed speed is 120 meters/min, with repeatability of +0.1 mm. www.aimmachines.com.

Cortinovis Machinery SpA Italy At wire Düsseldorf, Cortinovis Machinery SpA, part of the Eurolls Group, displayed a double-twist buncher specifically designed for manufacturing high-quality steel strand. The range of the machine allows the user to produce, using the double-twist process, strands from 7 wires up to 37 wires, utilizing wires from 0.1 mm up to 2.6 mm diameter. Bobbin sizes range from 250 mm DIN to 1250 mm DIN. The strand is formed by two pretwisters, with separate motors and deviation pulleys,

Cortinvois Sales Manager Raffaele Contini and Claudio Morara, general manager Eurolls China, by the doubletwist buncher at wire Düsseldorf.

Among the attendees at wire Düsseldorf was a team from Astoria Wire & Metal Products, which designs and manufactures high quality custom wire and fabricated metal products from its plant in Bedford Park, Illinois.

Founded in 1947, the family owned company offers a diversified range of products and services for sectors that include wire, tube and sheet metal. Below, company President Richard Zidek and Sales and Marketing Director Carolynn Zidek discuss their plans and goals for wire Düsseldorf with WJI. WJI: What did you do before you came to the show to prepare for your purchase?

Richard/Carolynn Zidek: Last year we spent over $900,000 in new equipment purchases. We have a very strong commitment to staying competitive in our manufacturing processes. Our feeling is, if companies don’t keep up with the times they will eventually become noncompetitive. In today’s global economy that is not an option for Astoria.

We knew we wanted to attend the Düsseldorf show to see what was out there but it’s interesting how this unfolded. Our process started in January when a team of seven visited one of the exhibitors (WAFIOS) at its U.S. office in Connecticut. Our visit was strictly to learn more about tooling options but while there we discussed some of the new innovations that would be released at the show. We suddenly became very interested in some new equipment options that originally were not planned for this year. We visited a second exhibitor’s U.S. headquarters and learned more. Then we called a third equipment supplier to see what they would be showing. Now there was not a doubt that we would be attending. One of the most difficult things about a show like Düsseldorf is we don’t have an endless budget and have to be very controlled. It’s more a question of what manufacturing process are we going to put our dollars in because we can’t buy it all. Going to the show really helps in narrowing it down.

WJI: How many exhibitors did you visit? What was your experience with the different representatives?

Richard/Carolynn Zidek: Our original plan was to spend serious time with the three exhibitors cited above.

We ended up spending serious time with 10 companies, which is a lot for the three days we were scheduled to be there. We also had casual conversations with another 10 companies. We were amazed that each exhibitor we visited had plenty of people in the booths to answer any and all questions we had. It was not a “high pressure-buy now” approach. It was more that the exhibitors made sure we had full knowledge of their equipment and how it would relate to Astoria. They made us feel that we were the only ones at the show even though we are a small company compared to some of the large companies visit-

ing. From a hospitality aspect, let’s just say we did not go hungry or thirsty while at the show.

We actually took our visit further. Besides visiting the booths we took two days and visited two of the exhibitors’ manufacturing facilities, which proved to be just as important as visiting the booths.

WJI: What capabilities in particular were you looking for?

Richard/Carolynn Zidek: We definitely had great interest in CNC wire forming with robotics and grid welding. The most important factor that we consider when purchasing a piece of equipment is service. If we have a problem, we want to know we will be taken care of in a reasonably quick matter. Also, the availability of parts and tools. Another extremely important factor for us is the setup time and the ease of setup. The machines only generate revenue when they are running, not when they’re being setup, so we want the ability to get that done as fast as possible, and have it be accurate as well as easy to do.

From l-r, the Astoria Wire team of Carolynn Zidek, sales and marketing director; John Smogur, director of operations; Kevin Zidek, vice president; and Paul Teska, maintenance manager, at the WAFIOS booth during their factfinding trip at wire Düsseldorf.

Cost is a factor but certainly not the No. 1 factor. For the vast majority of our past equipment purchases, we have chosen the most expensive because we feel with equipment you get what you pay for. That said, there are some out there that are really a quality piece for reasonable dollars. The location of where the machine is manufactured is not a factor in any way. We have purchased equipment from Japan, Germany, Switzerland and the U.S. WJI: What do you hope this purchase will enable you to do? Do you have any ROI projections?

Richard/Carolynn Zidek: This purchase is extremely important for our company in that originally we did not plan purchases for this year, but what we saw tells us that (continued on p. 64.)

Ernst Koch GmbH Germany At wire DĂźsseldorf, Ernst Koch showed the KHZ drawing component (see cover) of a line for cold drawing of large diameter wires, .375 in. (9.5 mm) to 1.875 in. (47.6 mm) that used to require two very strong employees. The cold drawing process of handling the rod coils, straightening the ends and pointing and feeding the rod coil took brute strength, and disengaging the pull-in dog was dangerous. Ernst Koch has developed and over time refined a system to make the cold drawing of the large diameters

The system includes the payoff (KAM), drawing machine (KHZ), a rebeding device and a take-up (KAH). The dual KAM wire payoff and bending machine takes the rod coil end, straightens the coil and feeds it to the pointing machine, which can be either a milling pointer, an oscillating roll pointer or a rotary swaging machine. Then, the pointed coil is recoiled while the other side of the dual KAM is feeding the KHZ drawing unit, which has up to 110,000 lb of drawing force. It accepts the pointed end from the KAM then grips it in an automatic built-in pulling dog grip that retracts into the 36- or 39-in. diameter horizontal drawing capstan after automatically discharging the coil end. A pressure roller set keeps the proper number of drawn wraps tidy on the diameter drawing drum. The coil is collected in a 45 degree angle tilted collecting drum, and after the entire coil is in the take-up device the collection device goes to straight for the coil to be stripped.

Koch also has optional ancillary equipment such as a coil compactor available for the drawing system. www.koch-ihmert.de, www.morgan-koch.com.

O.M. Lesmo SpA Italy Italy’s O.M. Lesmo SpA, represented in North America

by Lesmo Machinery America, Inc., reports that the company’s double-twist technology has been further improved by the use of an optional pre-twister for twisting insulated conductors. A double-twist buncher reduces the lay length by half when the product finally reaches the take-up reel.

This second twist poses one potential problem. The wires in the outer layers are tensioned while the inner layers are compressed, creating extra length in the inner layers. This extra length of wires can push through the outer layer and result in a “pop-out,” causing knotted strands on the final cable. This problem can be solved by using OM Lesmo’s pretwister, in-line with its doubletwist buncher.

The pre-twister is a rotor with idler O.M. Lesmo's new optional pulleys having pretwister. maximum rotating speed twice that of the buncher, or equivalent to the twist per minutes of the double-twist buncher. It is placed between the closing die-stand and the double-twist buncher and the members from the payoffs are guided through the closing die into the pre-twister guided by the idler pulleys. The lay length at the pre-twister approaches the final lay length and it will pull the appropriate length of members from the pay-offs. By properly adjusting the rotating speed of the pre-twister, the compression of members in the inner layer is reduced at the point of second twist on the buncher, thus eliminating “pop-out” problems. Proper synchro-

nization of the rotational speeds of the pre-twister and the double-twist buncher will produce a smooth and round final product. The pre-twister in conjunction with OM Lesmo’s double twist buncher can be used for manufacturing: flexible ropes (19 strands and higher), MCM sizes (up to 24 bunched members using OM Lesmo’s DTO1600 or larger double twist machines); cabling insulated conductors, where the pre-twister can maintain the position of low elastic yarns or uninsulated ground wires in the cable configuration. Reverse concentric products can also be produced in two passes using back-twist payoffs and a pre-twister. This is especially beneficial when producing AAAC and ACSR type of conductors as well as two-layer cables using insulated cores such as 2+8, 3+9, 4+10, 5+11 and 1+6+12. www.omlesmo.com, www.lesmoamerica.com.

Maillefer SA Switzerland From its portfolio of products exhibited at the show, Maillefer highlights two innovations: the Integrated Water Tempering unit (IWT) and its improved performance extruder MXC 120-24D (shown). Regarding the IWT, most of the different types of tempering systems currently available are not suited for the high demands of the power cable extrusion process, which requires water temperature control stability and reliability. A reliable and accurate temperature control, in addition to continuous adjusting and monitoring of the extrusion process, is a must to produce a high-quality, three plastic layered cable. The IWT is a fully integrated component of the extrusion line.

Tempered water circulation of the extrusion screws and the cross head flow channels are monitored, adjusted and controlled from the line control system, in the same way as the temperature zones of the extruder are controlled.

One IWT unit can handle up to five independently controlled water tempering modules on the same platform.

With a heating power of 6 kW and a water flow of 20 l/min., the unit is ideally dimensioned for a maximum temperature of 140°C and a maximum operating pressure of 11 bar. Each module is connected to the platform with

The highly efficient air cooled MXC 120-24D extruder is the company’s latest offering for various insulation and sheathing applications. The large processing window gives the MXC its unique capability to extrude several thermoplastic and thermoset materials such as PVC, polyethylenes, XLPE, HFFR, EPDM, plus other commodity and engineering plastics. The MXC benefits from improved temperature control due to the lower thermal inertia and the higher heat transfer rate of the redesigned heating/cooling elements. Thanks to a

At wire Düsseldorf and also at an in-house exhibition in its new factory in Schwabach, Maschinenfabrik Niehoff presented the double-twist bunching machines D 1001 and D 1201 (in Schwabach). The D 1001 type machine is designed for the manufacture of strands of up to 50 mm² (1/0) cross section for copper and up to 60 mm² (2/0) cross section for aluminum conductors with a lay length of max. 300 mm (11.8”). The machine is optimally suitable for larger strands and battery cables of both copper and aluminum. The winding force is infinitely variable and is controlled within tight tolerances across the entire bobbin filling using a closed loop load cell tension control system. The D 1251, the most recent model of the D series, can be applied to manufacture wire strands of copper with up to 95 mm² (3/0) cross section and aluminum with a maximum cross section of 120 mm² (4/0), which are used for the manufacture of underground cables and sector-shaped conductors.

Numallianceâ&#x201E;˘ France At wire DĂźsseldorf, Numallianceâ&#x201E;˘ showed the company's FTX technology, which replaces its existing line of FX wire benders. Is it possible to have a machine that can do it all: speed and flexibility, accuracy and user-friendliness, limited change-over, multiple material on the same platform? If such a dream machine exist, it would look like the company's FTX line, which process wire from 4 mm to 13 mm. Numalliance has put wire bending at the core of its know-how, branching out from there on other area : tube, flatstock or spring.

capabilities. The FTX is the only machine on the market that offers a whole area to perform offset bend and of course kept its iconic “Double Bend.” The Double Bend was recently pushed to its limits with the FTX as the machine was able to perform 420° of bend in one compound movement. The automotive seat business is the primary beneficiary of this development, since it can bend “round wave” spring seat wire with straight length in between two waves or at the end. It allows the production of lighter design and greater comfort springs for the seat.

The machine's “Touch & Form” interface now comes with an addendum called “Tool Editor” that enable the user to pre-program a part and simulate production realistically and also creates tooling for new applications. The system can also coil spring wire into compression spring, although it does not have unlimited rotation. Numalliance is also developing a new type of in-line press operation (coin, pierce, notch or mark) notably for production of wiper blade arms.

The front feed reduces the torsional effect of the wiredrawing operation relative to the standard feed, which is located far back from the bending tool. The SHARK’s front-feed advantage allows the feed rollers to be easily adjusted to remove the wire winding cast from the coil set, which can be difficult to remove completely with the wire straightener.

The SHARK’s wire line has been raised to allow standard totes to be placed directly under the bend head, thus reducing material handling. The wire line base allows for additional optional units for blanking, chamfering, grooving, drilling, etc.

The SHARK has a very heavy vibration-free base for stability. Electric controls are mounted in the base frame with an operator control panel independent to allow the best ergonomic position for the operator. Tooling changes for another wire size is about five minutes for the feed rollers, bend finger, mandrel and cutter. The SHARK can use the same tooling as the OMCG’s W10 CNC model.

Otomec: its earliest origins ...

One system that drew a lot of looks (but sorry, not for sale) from attendees at wire Düsseldorf was a wiredrawing system built by Metallurgica Rusconi, the predecessor company to Italy’s Otomec Srl. According to the company, this system was set up in Italy at the end of the 19th century in the Gerenzone Valley near Lecco, to produce any derivatives of wire rod, more specifically: wire, nails and fences. The end of the 19th century saw the introduction of new significant techniques that increased the productivity, such as the spread of ovens, the solder puddle (welding) and the diffusion of mechanized processes in many stages of production. Energy power was provided by ancient wooden wheels that, using water powerfrom the Gerenzone River, actuated a series of gears which, by means of leather belts, moved the flywheel of the drawing machine. At the time, the rod wire was put in a wooden tub for a first bath. Then it was drawn in the drawing machine several times in order to narrow the diameter down to the desired size. After this process the wire was again put in wooden tubs filled with a copper solution so to coat it uniformly. At this point a metalworker had to take the wire and organize it in small coils, ready to be used for subsequent derivatives. The system could just reach a speed of 10-20 meters per minute, but it was kept in use for nearly the first half of the 20th century.

... and the company today Italy’s Otomec Srl designs, produces and sets up cleaning and plating plant for wire and other products made from steel and nonferrous metals. The company’s OTO’FF line can process copper, alloy, aluminum and brass wires from 0.80 to 3.60 mm; steel and stainless steel wire from 0.80 to 2.40 mm. It can provide coatings with tin, silver, zinc, nickel, copper and gold at speeds of up to mt/min depending on the coating thickness.

Complete lines can be available as standard (spool-tospool basket-to-basket), multipurpose (spool and basketto- spool and basket, with optional accumulating device) and multiplater (double storage tanks, with fast change over of coating solution). The company’s process is controlled by electronic devices and the new machines can work both off-line and in-line with the wiredrawers at speeds up to 1000 mpm. Otomec plants are also used for pickling, degreasing and polishing: wire from 0.10 mm up to 12 mm; strips and sheets up to 500 mm widths; and bars up to 10 x 300 mm. www.otomec.it.

At wire Düsseldorf one of the focuses for Rosendahl Maschinen GmbH was highlighting production of finished power cables by merging power SZ with sheathing.

Being able to go from single insulated conductors to a finished power cable offers a lot of advantages for the manufacturer, and Rosendahl responded to that challenge by further development of technologies and improvement of processes. The result was a merger of Power SZ stranding and the sheathing process in one line. The equipment is ideal for producing low-voltage cable up to 1 kV with a cross section up to 240 sq mm² of each single conductor.

The perfect result of the finished power cable can be observed on the take-up reel. Thanks to the SZ technology, where no heavy mass is in rotation, the working principle is the same as that of conventional helical stranding systems. The payoff and take-up stands in the line are stationary reelers that need no special foundation.

The non-rotating reeler also helps to improve the line efficiency due to a very fast and simple reel loading and unloading cycle. As the reel does not need to be transferred between the stranding and the sheathing process, time and space saving is guaranteed. There is also no limita-

Tulsa Power’s new coiler, a new line of Automatic Cut and Transfer (ACT) coiling equipment, has generated tremendous interest not only in tubing and profile applications, but in wire and cable processes as well. The new ACT coilers have the ability to spool or coil and are fully automatic and highly reliable. The new technology and “no nonsense” design appear to address the customer identified weaknesses of other equipment offerings,

namely “overly engineered” systems and reliability issues. This series of coilers is adaptable for the toughest wire and cable application requiring accumulation, a contact dancer, hydraulic cutting and on-line printing to the ultra-critical micro tubing applications requiring non-contact, ultrasonic position control for extremely low running tension. The ease of operation and user friendly interface allow a single operator to oversee multiple lines generating a labor savings over previously used manual and semi-automatic systems. Couple an ACT coiler with now available on-line packaging equipment, i.e. multiple position twist-tie, stretch wrap, coil counting and boxing, and the process becomes even more automated and labor saving. www.tulsapower.com.

ces in toys, for example, or in drive and oscillating elements of mechanical clocks. A program-controlled displacement of the roller feed is possible via the height axis.

Thereby, the strip material can be guided tangentially from the edge where the strip material exits towards the coiling axis. The result is a considerable increase in output. Due to the intelligent star-shaped arrangement of slides, all kinds of spiral springs can be produced on the SPM 2. Besides these universal application possibilities, short tooling times allow an economical production of small batch sizes. The formerly used horizontal machine structure has been replaced by a vertical structure.

Thereby, several improvements were made. A better access of the tool room considerably facilitates operators

Wire Machine Technologies Israel Wire Machine Technologies CEO Yoav Dvir-Dahbash notes that his company is the only one in the world that has actual production capabilities to manufacture glasscoated wire below 15 microns in diameter. The company can sell finished micro-wires, but it is also willing to work with qualified strategic partners by supplying them the production machines on a lease basis. It can supply a wire production machine, a re-winding machine and an ILS package (documentation, spare parts, service and training). Capacity for one set is production of 500 meter per minute/30 km per working hour and 180 Km per

shift. Setup is quick (five minutes) and the equipment has a small footprint. There are no chemicals, pollution or hazardous materials and the system produces very little noise. The key is an innovative development process that coats the wire in glass. The process can use the same glass for all metal melt temperatures, and is not limited to a narrow melting temperature that can limit the types of metal elements and alloys that can be produced. The result of the process is a controlled homogeneous manufacturing process that meets all requirements. The continuous uninterrupted process can produce a 10 km of micro wire on a single spool. The process can work in four areas: amorphous metals (Fe, Ni and cobalt-based); conductive metals (gold, silver and copper); high-melting temperature wires ((platinum, stainless steel and DFeCr); and low melting temperature wires (Pb, Zn and Sn). yoav@wwmt-m.com, wmt-m.com.

(continued from p. 45.) the advances in equipment are coming fast and furious.

What we hope for is fast setups as I alluded to above.

The ROI question is a very good one. I know this does not sound like a good business practice, but in the past 67 years we never looked for ROI. We figured we would be able to generate increased revenue through better efficiencies. Not necessarily getting a return for the equipment itself. We are fortunate that most of our purchases are done with cash flow generated from operations so we usually donâ&#x20AC;&#x2122;t have an interest expense. If we do, it has typically been only for a short time. Now with the cost of more sophisticated pieces of equipment we need to start learning and looking at ROI. WJI: Have you placed an order?

Richard/Carolynn Zidek: We have not made our purchase yet. As much as we would like to get one of the systems we saw at wire DĂźsseldorf, we have to balance that need out with other considerations. So, we are still debating where to put our money this year, and it could an automated turret punching cell, a robot for our current

Even if we do buy another wire forming machine, we would still have to decide whether to purchase options for it that we do not need at this time but that if we do get them, it could give us capabilities that may help us with future opportunities.

WJI: Looking back, was there anything you might have done differently in the shopping process?

Richard/Carolynn Zidek: Honestly, I believe we really went into the show prepared. Visiting the two exhibitors prior to going really prepared us much better than just going to the show. Some of our questions were answered before getting there. Then, when we arrived, we were ahead of the process because of what we had already learned, which gave us more time to spend with other exhibitors we knew we wanted to visit. You always wish you had more time for a show like this, so the preparations prior to arriving is critical to a good show experience and leaving with as much knowledge as possible so the best decision can be made. If there was one thing the four of us would have changed, it would be to not to have eaten so much!

Outlined in the literature1 in 2009, the Surface Oxide Tester is widely thought to solely measure uniform surface oxides (USOs) but actually four properties contribute to its one total result. Along with USOs, the three other properties that contribute to the surface oxide measurements are: reduction efficiency, surface roughness and subsurface oxides (SSOs), when present. The SSOs are, by far, the most influential on copper rod test results, but heretofore their influence has proved to be extremely puzzling to cop-

per rod producers. For this reason, combined with the fact that SSOs almost always have a detrimental effect upon rod quality, it is important to be able to detect and quantify them. Thus, it is exciting that the research presented in this article provides a much better understanding of the influence of SSOs on the surface oxide test and presents previously unknown methods of detecting and quantifying them. Such methods will not only help to clarify uncertainties in the surface oxide test, but will also elevate productivity and performance of copper rod by both increasing the coil quality and lowering the required level of pickling agents, such as alcohol.

This article includes a foundation for understanding the importance of reduction efficiency and describes a new test accessory that is capable of directly measuring reduction efficiency for each test. Also, a new method is introduced that improves repeatability by allowing optimization of the measurement scales for both copper oxide constituents.

Although a method for measuring surface roughness has been developed, due to space limitations it will not be presented here. Likewise, discussions of basic concepts and recommended practices for surface oxide testing can be found elsewhere1-4.

Three other subjects in this articleâ&#x20AC;&#x201D;reporting of thickness instead of volume; a new discussion of foil testing as a physical calibration; and a new suggested deaeration practiceâ&#x20AC;&#x201D; serve as bridges to approaching more crucial concepts.

Thickness calculation assumptions Wire and cable industry test results are reported in terms of oxide thickness. However, the surface oxide test actually only measures the mass of the film components (constituents) present and not a thickness. In contrast, some researchers outside of the industry only report oxide volumes per centimeter of sample length. An advantage of this latter approach is the elimination of some testing variables.

For example, when converting mass (or volume) measurement to film thickness assumptions are made both that surface roughness can be neglected and that the film is of uniform thickness throughout. In addition, the presence of SSOs in rod adds to the volume of oxide material but does not contribute to the uniform thickness. Further, the thickness calculation assumes that all constituents, such as copper oxides, have theoretical densities. In contrast, surface oxides grown in rod production are typically porous. While this fact should not influence how the system is used in wire and cable, it is important to understand the correct nature of the films.

Inefficiencies in the QC lab style test The surface oxide test uses a technique known as coulometric reduction, which has been successfully employed for surface film analysis of corrosion coupons since the 1930s. This method can be performed so accurately that its confidence interval5 can be below one Angstrom (0.1 nm)6. However, to use coulometric reduction in its

the convenient but inefficient reduction test configuration, certain elements—such as dissolved oxygen, electrolyte contamination and reduction products—“steal” (or drain away) a portion of the hydrogen produced from reduction of the surface film. Historically, this test has used equations that ignore efficiency. For example, the equation for each constituent thickness is shown below in its simplest form for rod testing: Constituent thickness = Kc * timec * CD

Fig. 5. Testing of copper rod with subsurface oxides.

Each data point is the average of three rod tests in fresh but non-deaerated electrolyte. highly accurate form, the user must ensure that the test has 100% reduction efficiency, which requires significant time and effort both during test preparation and while testing.

This level of accuracy, however, is definitely not needed.

The test introduced to the wire and cable industry in 19772 made surface oxide analysis affordable and practical for the QC Lab. When used in the recommended configuration (especially including deaeration, electrolyte refreshing and proper curve-solving practices)1-2 the test is fast and has been used quite successfully as a grading tool. The downgraded rod coils are drawn on more forgiving machines to more forgiving end-products.

This coulometric reduction test causes hydrogen to be formed at the sample (cathode) by electrolysis. The amount of liberated hydrogen can be easily determined with very high accuracy because it only involves the measurands of current and time. In the 100% reduction efficiency test configuration, all the formed hydrogen goes directly to reduce surface oxides (or other surface films). However, in

extra operator maintenance. This accessory evaluates the electrolyte automatically after the test has finished (for greater accuracy it can be set to measure it before the test as well). Thus, it can also be used as an electrolyte monitor. Instead of the only two previous approaches that have been taken—namely, to ensure 100% efficiency or just concentrate on doing a good but unverified job of keeping that efficiency fairly consistent—now there is a third option that can also be combined with good electrolyte maintenance. See Fig. 1.

Lack of efficiency measurements has been a big barrier to improving repeatability for the following three reasons: the reduction efficiency (ε) changes from test to test, albeit this change is considerably less significant in well-maintained systems; improvements to the test configuration that improve repeatability also tend to increase reduction efficiency and thus change the test results, as can be inferred from Eq. (3), and consequently, grading criteria must be changed if ε is not measured, as shown in Fig. 2; and while the reduction efficiency (ε) discussed here is dependent upon the electrolyte only, the actual and overall test efficiency dramatically decreases when SSOs are present as they act as an additional current drain (discussed later).

Foil testing Before presenting data taken with the new efficiency monitor, here are some of the finer points of using copper foil for testing1. Copper foil is not a primary standard and foil manufacturers are not taking steps to control surface oxide levels. However, it can be used as a secondary standard inasmuch as the production of foil through cold rolling is a much more consistent process compared with wiredrawing and even more so compared with hot-rolled rod. Consequently, testing the surface oxide layer on copper foil has been an excellent method for demonstrating the repeatability of the system. Furthermore, most of the inner wraps of foil have a very consistent uniform oxide level.

As the thickness of surface oxide on foil is very thin, here are some observations/suggestions for foil testing.

• The cuprous oxide constituent on foil is so low that it is not discernable when testing at current densities typically used in QC Labs. Therefore, only the cupric oxide constituent is used for testing.

• Untreated foil has cupric oxides so thin that more accurate measurements are made at current densities somewhat lower than those typically used in QC Labs.

• After the outer wraps of the foil roll are discarded, the inner foil wrap should be cut and tested promptly to avoid an increase in those thin oxides which are very sensitive to the atmosphere or waiting in the electrolyte. A foil holder designed for the cell can make the test procedure swifter and more accurate. Also, more than one test at each condition may be taken and averaged.

• Typically, foil is tested with a surface area greater than rod. For example, a 50-mm-wide foil with the length in the electrolyte the same as a straight 8-mm-diameter rod, is just over four times greater in surface area than the rod.

This brings the volume of the oxide reduced closer in comparison.

• Foil can be heated to increase the surface oxide thickness, but the thermally grown surface oxides have different structures than those produced in metal-working processes.

Using the efficiency monitor with foil testing Copper foil samples were tested at three different current densities and at two electrolyte states, namely, in an electrolyte with high dissolved oxygen (DO) levels (8.2 mg/l) due to refraining from applying deaeration and in an electrolyte that was deaerated to very low levels of DO (1.3 mg/l). A measurement of reduction efficiency was taken for each test, and all of these results are presented in Table I and in Fig. 3.

TECHNICAL PAPERS

Deaeration influence on reduction efficiency Current density is directly related to the rate at which hydrogen is produced at the sample surface. However, the primary mode of mass transport of dissolved oxygen (DO) molecules in the electrolyte is via diffusion. As such, the rate at which dissolved oxygen molecules arrive at the sample surface is approximately constant. When a dissolved oxygen molecule arrives at the sample surface it is immediately reduced during the test. In other words, the dissolved oxygen molecules are reduced before surface oxides are reduced, because of their lower reduction potentials.

The data in Table I and Fig. 3 reveal that the combination of these two rates (namely, hydrogen production and DO molecule diffusion) results in the reduction efficiency decreasing with decreasing current density for foil testing.

As current density is reduced, the rate of hydrogen (H2) generation approaches half the rate of DO molecules arriving at the sample (each with an O2 molecule lightly bonded to a water molecule via dipole-induced dipole force), and the reduction efficiency approaches zero.

Other molecules contaminating the electrolyte may include charged particles, whose mass transport are dominated by migration instead of diffusion. When such molecules are present in abundance, the relationship between current density and reduction efficiency may be different than that shown in Table I and Fig. 3.

Table I shows the result of reducing the dissolved oxygen to a level considered very low for QC lab tests, namely, 1.3 mg/liter. The reduction efficiency still reduces as current density reduces, but the latter has much less influence.

Furthermore, the reduction efficiency remains much higher for the very low DO tests and is closer to 100% efficient for all three tests. Therefore, it is advantageous to perform foil testing at these “very low” DO levels (even with the use of the efficiency monitor), for three reasons: • Lower influence of current density on test results.

• Faster testing for a given current density (since more of the H2 goes to reduce the film constituents).

• More accurate testing since error analysis would reveal that it reduces the uncertainly from efficiency measurement, which is less accurate compared with the quantity of generated H2 measurement.

Although very low DO levels are advantageous in foil testing most QC labs do not employ this condition as previously there had not been a convenient and inexpensive means to monitor the DO level. (Handheld DO meters are too time-consuming to use before or after each test in the QC lab.) It had been thought that it would take much too long to get such low DO levels.

Both problems have been solved mostly by the addition of the new efficiency monitor. Even though this monitor measures the efficiency influenced by contaminants other than DO molecules, familiarity with how a given deaerator apparatus influences reduction efficiency in otherwise pure electrolyte will help to indicate when other contaminants are present.

Table 2: Influence of dearation time on DO levels using improved dearation.

Confident Instruments redesigned and began shipping a more efficient deaerator in 2010, which reduced the DO level from slightly above 8 mg/l for freshly mixed electrolyte down to the “very low” level of 1.3 mg/l with only 85 seconds of deaerating time, as shown in Table 2.

Using improved deaerator Heretofore, a recommended deaeration time for the electrolyte was between 10 to 15 seconds after it was refreshed and then again after every test. However, it appears that a better strategy is to deaerate the refreshly mixed electrolyte when it has been added to the cell down to the “very low” level (~1.3 mg/l) and then deaerate for a shorter time after every test. For this deaerator the initial deaeration time can be only 85 seconds (as per Table 2) and then 10 seconds after each test should be sufficient to maintain this level. If the system is idle for significant time due to line downtime, a greater deaeration time should be applied before the next test after the downtime. Deaeration using nitrogen or argon for 85 seconds still has a very insignificant cost.

This new technique ensures that the DO level is consistent from test to test and can be verified with the efficiency monitor, even during rod testing. It enhances repeatability because the DO Level is always known, unlike the previous method of only applying short deaeration times.

Fig. 4 shows foil data taken before 2010 using the old deaeration method as well as the less efficient deaerator.

The phenomena of reduction efficiency decreasing with decreasing current density has again been observed. This data combines tests where the cell was deaerated for 10 seconds after each test with data having 15 seconds deaeration times. The latter showed less influence of current density than the former, but not a dramatic difference.

Because the tests in Fig. 4 were not deaerated as thoroughly as with the “very low” tests of Fig. 3, higher current densities had to be applied before it reached the same high reduction efficiency. For example, in Fig. 4, the data point near 0.5 mA/cm2 current density is about 9 Ǻ, which is equivalent to the tests in “very low” DO electrolyte of Fig. 3 where 10 Ǻ is reached at only one tenth the current density. So for testing foil, and some wire, high current densities can result in high test efficiencies.

Influence of subsurface oxides on results The influence of current density on foil may not be of great concern for many rod producers since typical current densities used in rod plant range from 0.15 to 0.5 mA/cm2, which is the high range of tests in Figs. 3 and 4.

Consequently, for foil and most wires, with any deaeration practice and proper electrolyte refreshing, the reduction efficiency should be high and of little concern. However, for rod producers, of much greater concern is the influence of subsurface oxides (SSOs). Fig. 5 shows tests made on rods containing SSOs. Three rods samples were tested and averaged for each data point and they were performed in a freshly mixed electrolyte without any deaeration. The relationship of current density for the rod tests is very different than for foil tests of Figs. 3-4. Foil, most wire and some rod, exhibit the very predictable relationships between reduction efficiency and current density of Figs. 3 and 4.

However, when SSOs are present in the rod there are dramatic changes. See Fig. 5. The influence of SSOs will be different for each rod source since the SSO to USO volume percentage will be different as will the geometric characteristics of the SSOs. Thus, the relationship between current density and test results will not always appear exactly as shown in Fig. 5 when SSOs are present.

Origins of subsurface oxides (SSOs) Subsurface oxides are created by events that can be broken into three categories: 1) less than 100% descaling, resulting in surviving scale being embedded in the rod by rolls downstream from the descaler; 2) copper covering

over scale before reaching the descaler, thus preventing the removal of the covered scale; and 3) copper covering oxide (not scale) any where after the descaler.

The reason for Cat. 1 faults is obvious, but there are multiple causes for Cat. 2 and 3. Cat. 2 is heavily influenced by the casting practice. Three casting problems that readily cause SSOs are cracking in the casting wheel, hot cracks in the cast bar and fold-overs of bar corners. See Figs. 7-8.

Both Cat. 2 and 3 are influenced by rolling practice. One example of poor rolling practice is allowing overfills where copper is deformed into overly tight gaps between the rolls. These overfills are pressed back into the rod at the next roll stand resulting in copper flowing over the previous rod surface. Another example is continuing to operate the mill when there is significant pitting on the rolls. This leads to protrusions on the rod, which again cover over the portions of the surface at the next roll stand.

SSOs influence the surface oxide test when they are partially exposed to the surface and thus to the electrolyte, whose low viscosity allows penetration even into narrow folds. This exposure permits them to be fully or partially reduced during the test and thus inflates the test results.

Figs. 7-8 along with Fig. 6 show that there can be varying degrees of SSO exposure to the electrolyte. Some SSOs have no exposure such as the SSOs on the bottom of Fig. 7, which would not be reduced at all in the surface oxide test.

Principles governing the influence of subsurface oxides (SSOs) Models were created and tested to understand how SSOs influence the surface oxide test. Details on model creation and the results on model tests are in the appendix at the end of this article. At this point, only two key concepts will be presented and made use of in the next section.

tially reduced before the measurement is considered to be complete, namely, when the cupric oxide inflection point is crossed for typical tests. The SSOs will continue to be reduced after the cupric inflection and may be completely reduced, depending upon how long the sample remains connected, but this reduction is not added into the results.

The percentage of SSO reduction that influences the test is related to the degree to which the SSOs are exposed to the electrolyte, the geometry of the SSOs, the amount of SSOs relative to the USOs and the current density.

Principle of constant drawn current to SSOs. The fact that SSOs are not completely reduced during the test means that they tend to act like a reservoir, drawing the same percentage of current under different electrolyte conditions. To understand the full effect of this principle, it should be remembered that lack of efficiency is caused by dissolved oxygen and other contaminants “stealing” hydrogen molecules away from the reducing of copper oxides. This “stealing” (or draining) occurs because the majority of contaminants reduce at lower reduction potentials than copper oxides (both USOs and SSOs). So the SSOs can only obtain current flow from the current available after reducing draining molecules. However, the percentage of current drawn to the SSO is approximately constant regardless of the reduction efficiency the electrolyte allows. Thus, the degrees to which the SSOs elevate the surface oxide test results are dependent upon the test efficiency. For example, if the electrolyte has been conditioned such that a 90% reduction efficiency is possible on tests without SSOs, then when SSOs are present, which in this example draw 10% of the available current, the overall efficiency drops to 80% and increases the test results by 12.5%. However, when starting out with electrolyte that only allows 20% reduction efficiency without SSOs, the same SSOs would still draw about 10% and cause the overall efficiency to drop to just 10%, thus increasing the test results by 100%. So the same amount of current to the SSOs produces a dramatic difference in surface oxide results elevation due to reduction efficiency. The tests were all performed in electrolyte that was not deaerated and thus this dramatic change with current density is seen.

See Fig. 5.

Saving money. It is very important to know whether a high surface oxide test result is due to high USOs or the presence of high SSOs. Increasing the IPA content in the pickling solution (or rod cleaning) increases both material and environmental costs. However, increasing these additives will only reduce high USOs but will probably not reduce high SSOs, and therefore, will not eliminate problems caused by SSOs in terms of subsequent drawing issues. Knowing when subsurface oxides are present can alert plant managers sooner yielding faster remedies to production problems and therefore, less downgraded coils.

Five factors to distinguish between high USOs and high SSOs are listed below in order of convenience and definitive strengths.

• SO monitoring accessory for surface oxide testers. The most convenient method to monitor the degree to which SSOs are presence will be introduced as an accessory to the Confident Instruments’ surface oxide tester. It will perform its measurement automatically and during the same time required for most tests.

• Dual dissolved oxygen level testing. This test configuration makes use of the “Principle of Drawn Current to SSOs” described earlier. It involves setting up two cells or two full surface oxide testers. One cell should be maintained at the “very low” dissolved oxygen level as has been described herein, namely, ~1.3 mg/l. The second cell should be either without any type of dissolved oxygen conditioning to provide the “high” DO levels used in testing here (7.5 to 8.3 mg/l) or should be saturated with dissolved oxygen by supplying filtered compressed air to the deaerator. The latter method is more precise and consistent because dissolved oxygen saturation always occurs at a precise level for the same temperature, electrolyte concentration, and purity.

In this configuration, there would be use of a “Foil Ratio” which is found by measuring foil in each cell. Using example test efficiencies of 0.90 for the low DO level cell and 0.20 for the high DO level cell, the foil ratio would be 4.5.

In other words, testing foil in the high DO level cell would produce results 4.5 times higher than testing in the low DO cell. With such a foil ratio established, performing a test on rod with enough SSOs to draw, say, 10% current to themselves during the test, the ratio would shoot up to 8 on the drawn current principle alone. Thus a ratio significantly higher than the foil ratio indicates the presence of SSOs and the degree to which it exceeds the foil ratio characterizes the level of SSOs present. Further discussion of this test configuration is continued on the web site4.

• Examination of hot-rolled rod, wire, fines and cast bar.

Since subsurface oxides (SSOs) are easily detected by metallographic analysis, their formation can be traced to its original source. It is convenient to first inspect the cast bar cuttings for hot cracks. If the cast bar does not show sources of subsurface oxides, a “fishpole” can be analyzed and a mill constant analysis can be performed. However,

since examination of fishpoles is rather time consuming, it may be more feasible to employ a method for tracing fines generation sources in drawing, as was introduced7.

Samples are collected from mill emulsions localized to individual stands after the descaler. Those samples can be filtered in the laboratory to reveal weights of fines in the emulsion.

Metallographic polishing and etching of cross-section will clearly indicate the presence and nature of SSOs in the rod, as represented by Figs. 6-8. Twisting the rod can help pinpoint the location of SSOs because cracks usually form where SSOs are present. While this method yields very definitive results, it is also very time consuming.

Some plants monitor the surface integrity of their rod and wire with eddy current or EMATs (a form of non-contact ultrasonics), which might indicate when a problem started to occur. Lasers or other non-contact monitors may also be an option for detecting overfills, flashing, and bar-corners.

• High variability. When SSOs are present the overall surface oxide results often display high variability, because the formation of SSOs is usually periodic in nature. Causes of SSOs include cracks in the casting wheel, hot cracking in the bar caused by high levels of impurities such as lead or bismuth, coining of oxide particles into the rod surface during hot-rolling, or excessive worn spots on rolls.

Examples of SSOs from these periodic issues were shown in Figs. 7 and 8. Some think that because the line is highspeed the volatility of surface phenomena should be low.

However damage to one part of a roll, for example, can impart damage to the rod at the same intervals no matter how fast the line moves. In addition, there are issues that can cause SSOs of a more consistent nature, namely, overfills or flashes at the bar corners (often referred to as “batwings).” See the resulting SSO in Fig. 8.

Often SSOs are scale, which are grown at a temperature range where mostly cupric oxide forms. Therefore, the high variability tends to be seen in the cupric measurements and often the cuprous oxide values are quite consistent and have a low standard deviation. Thus it may be further dramatized by both volatility and a higher CuO to Cu2O ratio.

Since QC Labs typically test only one rod sample per coil, it is important to use SPC or to display a history of past coil tests in order to spot this volatility associated with SSOs. This feature is so important, that an SPC display is provided on the gLCD Touch Screen, which provides easy interaction for managers.

• Twist testing combined with surface oxide testing.

Torsional twisting of rod places stresses on the surface that tends to produce cracks and open-up fissures near SSOs9.

As twisting proceeds, the brittle SSOs frequently fracture and exfoliate. The optimum degree of twist testing exposes SSOs without causing significant exfoliation. Previous research on ETP rod showed that a 5x5 twist test for 8 mm rod is the optimum level of testing to be performed prior to surface oxide testing10. It would be more convenient to use 10x10 twist testing since many labs already employ this

test as part of their grading. Unfortunately, the surface oxides tend to exfoliate during the 10x10 level, and thus are no longer capable of being measured by the surface oxide tester.

When subsurface oxides are exposed by 5x5 twisting, the resulting surface oxide values are usually significantly higher than before twisting. The 5x5 twisting process can also be combined with the Dual Dissolved Oxygen Level Testing Method. Furthermore, there are plants that already routinely combine a method of capturing and weighing vaulted-off fines with their 10x10 twist test.

copper that have been separated from the bulk copper. A percentage of subsurface patches will be completely exfoliated as fines and thus will not harm further drawing passes. However, a significant percentage of SSOs will survive the coarser die passes and may cause the aforementioned problems. These surviving subsurface oxides are especially troubling for magnet wire because they can open-up during annealing, thereby forming fissures that can hold excess enamel, which in turn hinder the vaporization of solvent during the curing process resulting in beads12. A metallographically polished wire showing SSO scars is seen in Fig. 10.

Consequences of high uniform surface oxides and high subsurface oxides

Important concepts of curve solving

Subsurface oxides (SSOs) or rolled-in scale both tend to originate as casting scale and, as such, are much greater in thickness compared to the uniform oxide films (USOs) present after alcohol or acid pickling. While rod with either high USOs or SSOs will not draw particularly well, their consequences will be somewhat different.

High uniform surface oxides. Rod having very high surface oxide thickness is difficult to draw in the rod breakdown machine2. It has been postulated that this problem occurs because the oxides will not allow a strong boundary lubricant film to form. However, the reverse is actually true because as the generally porous surface oxides become thicker, the surface energy of the rod surface increases.

What actually makes drawing rod with high oxides difficult is the fact that the brittle oxides tend to fracture and break off when drawn and when the oxide thickness is too high there is more oxide materials breaking off. These oxides not only tend to clog the draw die entrance, they trap lubricant molecules leaving the inner and deforming portion of the die with a scarcity of polar molecules.

Furthermore the oxide particles tend to form copper soaps that may also aid in clogging actions7.

Along with less effective boundary lubrication, the surface oxide film crumbles apart due to both the tribological contact and the expansion of the work-piece surface, causing micro-fine and abrasive particles introduced to the deformation zone. Thus, higher USOs cause more die wear, which in turn is more likely to cause wire surface damage. In contrast to SSOs, it is possible with good drawing practice to have little negative influence of high USOs after the rod breakdown machine.

High subsurface oxides. Unlike high USOs, high SSOs in rod extend their detrimental influence all the way to the finished product. They have a strong and immediate influence starting in rod breakdown machine by increasing fines. More fines being generated further accelerate the fines generation process7.

Unfortunately, even when most of the fines are generated and removed in the rod breakdown machine, oxides still remain in the wire and can cause wire breaks or enamel faults when the wire is drawn to finer sizes11. The influence of SSOs can be seen in Fig. 9 from oxides that fracture during drawing and sprawl off along with layers of

Users of this electrochemical test in labs other than rod plants, such as R&D, corrosion, tire cord and art restoration usually search for inflection points on the curve. These correspond to the peaks in the test curveâ&#x20AC;&#x2122;s first derivative and are the recommended method of solving these curves by most researchers. In contrast, using times indicated by predetermined voltage levels is much less accurate and dependable.

R&D workers in other labs optimize the conditions to produce clear inflection points. For example, when a material of unknown surface properties is received, the first test performed may simply guide the worker in setting up the best conditions to obtain clearer results for testing subsequent samples. The main parameter they adjust is the current density but also electrolytes and their concentrations are adjusted to obtain the best test results.

Of course, this practice cannot be copied in the rod QC lab for two main reasons. First there is usually only time to test one sample per coil. Second, even if there was time to test multiple samples, due to the testing at less than 100% reduction efficiency it is prudent to maintain consistent conditions from test to test. Consequently, conditions are set once and held constant for every test. Although, there are times when these conditions reveal all inflection points non-ambiguously, other times the best inflection points can be harder to find.

In quality control rod labs, the current density tends to be set so high due to time demands that sometimes the cuprous oxide inflection point is not discernable in the curve. Not only are oxides being reduced too fast to reveal the peak, but they would be too close to the start of the test where the filtered first derivative values are still settling.

Perhaps a more problematic case than the cuprous not being discernable at all, is when the cuprous is discernable sometimes and other times it is not, which sets up a situation where the values of the cuprous jumps back and forth from zero to substantial values. This can easily cause a flitting of 20% of the total value. Such a practice reduces the repeatability of the results.

Fig. 11 shows foil tested at three different current densities, namely, 0.100, 0.050 and 0.025 mA/cm2. Using the curve solving method that seeks inflection points, the first two tests (at higher current densities) would indicate the

Summary and conclusions The surface oxide test has been very valuable in grading rod since the late-70s. However, this paper has focused on factors that influence test results, especially subsurface oxides (SSOs) and test efficiency. Understanding these influences and taking the steps to either improve the test or to better diagnose the line yield substantial cost savings via better grading and swifter production remedies.

The influence of SSOs was determined by studying test data and the characteristics of SSOs, which led to development of models for experimental SSOs simulation in rod.

These experiments yielded key concepts, two of which were presented in the main paper, namely: • The SSOs are only partially reduced during the test time used for the calculations, resulting in a reservoir effect that always draws current.

• This reservoir effect drains the current available after reducing drain molecules of either dissolved oxygen or other contaminants, thus dramatically elevating oxide values for tests performed with little to no deaeration and/or infrequently electrolyte refreshing.

Means to distinguish between uniform and subsurface oxides were discussed, and included long-known methods

as well as new methods that grew out of the research findings, namely: • An accessory that will conveniently monitor for the presence and strength of SSOs automatically during each surface oxide test, and is presently being developed.

• A method for monitoring the presence and strength of SSOs has been described, making use of dual cells at substantially different dissolved oxygen levels.

• Metallographic examination of hot-rolled rod, wire, fines, and rod after twist testing.

• Variability of test results are also an important indication of subsurface oxides, and is related mostly to the variability for the cupric oxide constituent.

• Twist testing combined with surface oxide testing was discussed in regards to how this method can be used effectively.

Consequences of having both high uniform and subsurface oxides in rod were described and include such problems as poor drawability, inferior lubricity, wire breaks and excessive fines generation.

Accuracy and repeatability improvements for the Surface Oxide Test have been realized via a number of innovations: • The development of an accessory for the Surface Oxide Tester that measures reduction efficiency during each test.

Experiments conducted by testing of copper foil exemplify the monitoring of reduction efficiency.

• A new method has been described for managing dissolved oxygen, with the goal of holding dissolved oxygen to what had previously been considered a “very low” level.

• A new method was developed to determine more accurately the presence and amount of cuprous oxides in rods, wires or foil, which has been given the name, “Dual Current Density Method,” because it employs two different current density values during the test.

Other issues were discussed to bridge the concepts mentioned above, such as the pros and cons of reporting oxide results as either volume or thickness and proper practices in using foil testing for test analysis.

absence of cuprous oxide. However, for the third test an indication of cuprous oxide is obtained. Of course, the cuprous constituent is present on all three foils tested, but could only be measured at the lowest of the three current densities (0.025 mA/cm2). A similar effect occurs with rod at high current densities.

In order to improve repeatability and accuracy, a “Dual Current Density (DCD)” Method has been developed for the Confident Instruments surface oxide tester. The test starts at a user-selected low current density that allows the cuprous oxide inflection point to be easily detected. When the curve crosses a user-selected voltage value, the surface oxide tester automatically increases the current density to a value that will process the CuO reduction at a speed fast enough to keep up with production. An example curve produced by this method is shown in Fig. 12. It can be seen that the curve takes a jump in voltage level at the current density transition point, in line with research in the Appendix. A voltage level is set to trigger the transition or the transition can be initiated manually.

While this Dual Current Density (DCD) method is new to surface oxide testing, it is really analogous to the best practice employed in most instruments, namely, the ability to optimize the scale for a given measurement. In the past, cuprous and cupric oxides were always measured at the same current density, thus the same “scale”. A better approach, introduced in the DCD Method, is to use two “scales.” Not only does this method solve the larger threat to good repeatability of flitting between zero and a significant value of cuprous, but it also determines cuprous oxide thickness’ more precisely because a more appropriate “scale” is used. Calculations used with this method can be seen at the web site4.

Appendix: Determining the influence of subsurface oxides from model testing: Simulating Subsurface Oxides (SSOs)

SEPTEMBER 2012 | 79

TECHNICAL PAPERS

This section discusses testing subsurface oxides models in order to understand how they influence the Surface Oxide Test. It is emphasized here that QC Labs do not necessarily have to construct and use these models, which are used here only for research.

Since the influence of SSOs, as highlighted by the data of Fig. 5, is of great concern to many copper rod producers, it has been imperative to seek a better understanding of their influence upon the surface oxide test. One approach might be to obtain, analyze and characterize numerous SSOs on rod, which would require a considerable research effort.

An alternative is to create approximate models of the SSOs and to refine those models as understanding of the phenomena increases. Presented in this paper are data from one model that will be shown to illustrate a handful of key concepts.

Initial concepts for SSO models have been determined from metallographic examination of twisted rod9, from Rod Fines Potential Analysis7 and from observation of SO test results, such as shown in Fig. 5. Figs. 6 to 8 show metallographically polished rod cross-sections revealing subsurface oxides. The majority of these oxides originated from casting scale that was embedded into the rod surface during hot rolling. An extremely large (relative to the USOs) piece of scale was seen that had a significant percentage of its area exposed to the surface. From observa-

tions of these type of SSOs, Model A is developed, as illustrated in Fig. 13, and represents a patch of oxide much larger than the thickness of the USOs. Model B, shown in Fig. 13, has a gap between oxide layers. This is acceptable because while SSOs appear solid, many are in fact, somewhat porous and have cracks extending from the rod surface to the interior. The very low viscosity electrolyte (much lower than water) seeps into these SSOs, displacing air, and can reduce them.

Metallographic examination led by twist testing provides a very limited sample of the overall population of SSOs. However, input in developing models has also come from Fines Potential Analysis (FPA) of rod that was introduced in a 2009 WJI article7-8. In a brief description of one FPA configuration, thoroughly cleansed rods were twist tested, which caused the brittle SSOs to rupture thus liberating the SSOs and the copper layers above them. These fines were captured and analyzed, revealing a flake-like predominant characteristic that was consistent with many rod sources tested. In this method, it is also important to section the fines to gain an understanding how they were formed based upon the geometric oxide patterns in the fines. This approach analyzes the entire rod surface at once and thus may be a valuable overall view of SSOs to combine with metallographic analysis of rod.

Fig. 14 shows how Models A and B for SSOs have been simulated. It depicts the typical Surface Oxide Test configuration with a sample (copper foil in this case), a reference electrode and an auxiliary electrode. However, for this simulation the sample is electronically split between a main sample (a long length of copper foil) and the SSO simulator. A constant current is provided to the overall sample as in typical surface oxide tests. Fig. 14 shows the use of two 10-ohm resistors allowing the monitoring of the current drawn off the constant current to the simulator. For Model A, the SSO simulator is simply a shorter length of copper foil and for the best approximation of Model A (Fig. 13),

the shorter foil can be processed to increase its oxide thickness to be higher than the longer (main) foil.

However, in this article, data is shown for Model B and in that case the simulator is more complex. The simulator for Model B is shown in Fig. 15 and depicted in Fig. 16. Here the shorter length of Table 3. Surface oxide results for simulator tests at various current densities and copper foil is sandwiched dissolved oxygen levels. between plastic sheets, but with gaps on each side of the foil spaced by plastic shim, which are much thicker than the double layer and thus does not impinge upon it. As seen in Fig. 15, the electrolyte moves higher in the simulator than the cell level due to surface tension. The total area of the simulator foil that is wetted by the electrolyte is measured for these experiments. In Fig. 14 a switch is shown in the model to simulate a transition between USO and SSO reduction. However, for the data presented here, for simplicity, the switch remained closed throughout the test.

Finally, a Luggin capillary was added to the simulator and its center was positioned at 8 mm above the simulator bottom. It allows the monitoring of the voltage at this position in the simulator.

The data presented in Fig. 17 and Table 3 used simulator shims 1 mm thick and the area of the simulator foil wetted by the electrolyte was about 14.5 percent of the total foil Fig. 15.

to find the cupric oxide (CuO) inflection point, which is the time used to solve for the total â&#x20AC;&#x153;thicknessâ&#x20AC;? of both the main foil and the foil in the simulator together. The surface oxide results, determined in this manner, are shown in Table 3.

The light blue curve (d) is the amount of current that flows into the simulator and the purple curve directly below it (e) represents the percentage of the total current flowing into the simulator. Notice that to the left of the CuO Inflection Point, the purple curve mostly stays below 10% and only rises to a maximum of 12% near the Inflection Point. Thus it always stays below the percentage of oxide in the simulator (~14.5%). The reason for this is that not all the oxide inside the simulator can be reduced at the voltage levels for reduction of oxides on the main foil.

As shown on the left side of Fig. 17 and in four of the six tests the simulator current starts out higher and soon drops

downward while the Reference Voltage is still fairly constant. This drop is due to the depletion of ions in the electrolyte inside of the simulator. Before the Reference Voltage is allowed to rise near the Inflection Point (and beyond) the simulator current remains at this lower level.

However, when the Reference Voltage is allowed to rise, due to completion of the oxide reduction on the main foil, the extra voltage required to drive ions up into the simulator by migration is now available. (This phenomenon is referenced elsewhere, such as by Miley13.) Thus, after the Reference Voltage rises, the Simulator Current rises dramatically and only levels off when the oxide reduction inside of the simulator is complete. A horizontal dashed light-blue line is marked on Fig. 17 to illustrate the simulator current level where copper oxides are no longer being reduced and hydrogen gas is now formed inside the simulator. Therefore, these test curves show that a significant portion of the simulator oxide is reduced after the test is considered to be completed and thus is not counted in the test results. Further results are shown in Figs. 18-20.

TECHNICAL PAPER Benefits of the two-roll rolling process on aluminum and copper rod This presentation describes how experience and research by two companies led to the evolution of two-roll rolling mill technology that resulted in dramatic increases in productivity and quality of aluminum and copper rod.

by Wade P. Krejdovsky, Ketav Patel and Noell Wilson

Southwire (SW) and Siemens (formerly the Morgan Construction Company) have cooperated together since a formal partnership was drafted in 1965. SW has sold 85 continuous-cast SCR® (Southwire Continuous Rod) copper rod systems worldwide using Siemens rolling equipment. The SCR continuous-cast system is a world leader in ETP (electrolytic tough pitch) copper rod production because of its ease of operation, low operating costs and high operating efficiencies in producing quality rod to meet international standards. Southwire also sells SCR systems to produce EC (electrical conductor) grade, electrical alloy and mechanical alloy aluminum rod. The two firms have worked jointly as well as independently within their center of competence to improve the production and quality of nonferrous products rolled on their systems.

The system has the No-Twist mill arrangement of stands. It has a roughing mill of alternately arranged horizontal-vertical stands followed by a finishing mill also consisting of alternately arranged horizontal-vertical stands. The pass progression is oval-round with the exception of the first stands which reduce the typically trapezoid shaped cast bar.

Historically, each cross-sectional area reduction will range from 30-36% in the roughing stands and 20-30% in the tied No-Twist finishing mill1. Today, reductions can top 40% in the roughing mill and 35% in the individually driven finishing mill.

History of the equipment The mills provided by SW and Siemens were, and still are today, built to last. The original SCR-1 mill—installed in Carrollton, Georgia, USA, commissioned in 1965—is still rolling today after being relocated to Taiwan. A mill provided in 1968 for Palabora, South Africa, is still rolling today without having had any major modifications to the mill in 43 years. Most of the original rolling mills are no longer in operation today, but the individual stands from many of these mills have been moved and integrated into existing mills.

Innovations in productivity and quality Innovation has been a hallmark of SW and Siemens cooperation over the years. The entire SCR system is continually evaluated and improved. SW has a copper mill and three aluminum mills for development and testing. Some of the major innovations and incremental improvements that have pushed production and raised quality are independently driven finishing mill stands, the hydraulic roll mounting, the exponential coiler pipe, the No. 2 shear and rolling guides.

Independent stand drives Traditional rolling technology for aluminum and copper implemented area reductions of about 30% in each rolling stand. As the stock approached the final stand the normal procedure was to reduce the reduction in each stand with “leader passes” and final passes that tended to do less work and less reduction. However, when a change to larger size rods were made, the rolling would stop earlier in the mill and the finished rod would come off of stands that were doing a 30% reduction with no ill effects. Knowing this, designs started to be more aggressive with the reductions in the mill. Gradually the reductions changed from 30% to over 40% in each stand.

This reduced the number of stands required to roll a given area cast bar to the smallest desired rod section of 8 mm.

Shortly after going to heavy reductions the cost of small to medium variable AC (VAC) drives and motors dropped to competitive levels and it became practical to make a finishing mill with eight small to medium individual motors rather than one or two larger motors driving multiple stands. The motor selection can be fine-tuned to provide appropriate power at each stand depending on the work being performed.

By using a stand-by-stand basis, motor selection becomes more efficient and overall power consumption can be less than using one, larger motor driving the tied stands.

In the individually driven finishing mill, the horizontal-vertical rolling train requires two shafts with couplings at each rolling stand. This configuration of two-shaft reducers pro-

alignment, longer roll life and less running eccentricity in the roll, which improves rod size tolerance.

Exponential coiler pipe Several improvements were engineered in the coiler area to improve the quality of the rod. The radius of the rollerized turndown changed from 1 m to 1.5 m. This longer radius greatly reduced the effort to push the rod through the horizontal-to-vertical transition. The load on the pinch rolls reduced with the longer radius.

In addition to the new rollerized turndown was the introduction of the “exponential coiler pipe” that replaced the “cardioid” design. The new pipe curve changed the length over diameter ratios that allow for a longer and smoother path. This has resulted in significant improvements to pipe life. The combination of rollerized turndown and the exponential coiler pipe results in a softer rod from undergoing less work hardening. Orbital or laid coiling are options provided on new mills.

No. 2 shear As cast copper bars got bigger, the rolled front end would develop a ragged convex shape that progressively got worse with each stand. After several stands the front end would sometimes split and cause a cobble in the mill. In the old wire bar mills, the practice was to periodically cut off the front end section and to feed a new sheared end into the mill rolls.

The intermediate shear accomplished the same thing on larger mills, eliminating the split front ends prior to entering the finishing mill. This minimized the effect of finishing mill cobbles by cropping all of the stock between the No. 1 and No. 2 shear instead of requiring that it be removed manually.

Hydraulic roll mounting can be provided in both the roughGuides specifically designed for non-ferrous ing and finishing mills. Mill rolls were originally manually Siemens has used its expertise of guide design and tailored assembled and disassembled in several steps. The installation it for the nonferrous mill. Static entry and delivery guides are could vary depending on the size and strength of the operator. The parts could be assembled yet still not run true.

Hydraulic mounting brought consistency to this operation and allowed the operators to leave the heavy work to the machine and to concentrate on precisely installing the parts in the correct sequence.

Besides the benefits realized in production, arguably the biggest benefit of hydraulic roll mounting is the increased operator safety.

The hydraulic pump and accompanying tools facilitate the mounting and dismounting of the hydraulically mounted rolls. Hydraulic Fig. 1. Stands, reducers and motor layouts of tied finish (left) and individually driven mounting gives precision finishing mill (right).

vides less cost than driving through six, three-shaft reducers.

The alignment and commissioning of the drives and reducers are also more accurate and less time consuming. Proper alignment of the reducers on multiple axes in a tied mill was a cumbersome and potentially inaccurate process. See Fig. 1.

The above changes allowed the area of the section going into the 8-stand finishing mill to increase from 700 mm2 to 1300 mm2, which reduced the number of roughing mill stands that a customer had to buy for a given tonnage rate.

A quality benefit is that, for rod size changes, the pass design was no longer limited to the reductions that were built into the fixed gearing of the finishing mill. On a single stand, a larger rod can be finished out of a process round of the approximate required area by changing the roll grooves shape, reductions, roll parting and motor speeds. The reduction of tension or compression in the pass sequence resulting from the individually driven stands improves the general rolling stability and ultimately the final rod size tolerance.

An additional benefit of using independently driven stands is the roll life. If the stands were tied, all the roll diameters in the entire finishing mill had to be within a set, tight tolerance to maintain acceptable tension levels. All of the rolls in the finishing mill had to be grouped together based on diameter.

This would sometimes result in excessive grinding on some rolls to match the diameter of others, a costly practice wasting roll material. Because the stands are no longer tied to one another, there is flexibility in the diameters of the rolls used.

The operator now has the ability to manipulate the speed at each stand to maintain appropriate tension levels for the given roll diameter. This function allows additional regrinds of the mill rolls for significantly extended mill roll life.

used to provide support for stable sections entering and leaving the stand respectively. Roller entry guides are used on unstable sectionsâ&#x20AC;&#x201D;typically ovals, flats and diamondsâ&#x20AC;&#x201D;to ensure the section enters the pass in the correct orientation.

The guides also help reduce scratching and provide a method for cobbles to escape, thus protecting the roll. The design of the guides has changed over the years in order to improve life, improve rod quality and reduce operating costs.

Some guides from 1950s are still used in some SCR systems. These guides have individual adjustments for each roller holder and this can lead to inconsistent setup methods.

The guide rollers utilized bushings lubricated with grease.

The A-Series guides, designed in the 1970s, are still in use today. These guides also employed individual roller holder adjustments. The roller bearings could be lubricated with either grease or air/oil. The smaller guides could be setup with mechanical gauges or optics.

The ASR-Series guides were created in the late 1980s. The guides provided individual or symmetrical roller holder adjustment. A height adjust-

ment was also provided. The use of bench optics provides consistent setting of guides in the roll shop, eliminating variability from operator to operator who would manually use gauge bars or cobbled bar sections to set up the guides.

Study on capacity increases Since their inception, the SCR systems have increased in size. The increases have included the cast bar size and the reductions taken at each rolling stand. A more aggressive roll pass design has been instituted in the recent years.

To make the increased reductions at each stand, the stands must be able to withstand the forces acted upon it by the rolling process. There are two types of housings used in the nonferrous mill ,depending upon the type of the roll neck bearing. The roll neck bearing is either an oil film bearing or a roller bearing. The oil film bearing provides a higher rolling capacity than the roller bearing. The oil film is more com-

monly used on today’s stands. Thin shell-oil film bearings allow the stands to use large diameter shafts, minimizing the deflection under load. Studying and developing the oil film bearing application has resulted in increased capacity. Bearing capacity curves have been updated over the years and today’s stand capacities have exceeded the initial theoretical limits1.

Older SCR systems used 12 stands to reduce a 5.0 sq.-in.- cast bar (3225 sq. mm) to the required rod size2. Today, a modern SCR systems incorporates a pass design utilizing the same number of stands (12) reducing a 10.6 sq.-in.-cast bar (6850 square mm) to Fig. 6. Aluminum stock area reduction in eight-stands at two mills. the same rod sizes, an increase of more than 212% area reduction for the entire system. The original SCR-1 system in Carrollton, Georgia, used 12 stands to reduce a 2.8 sq. in. (1806 sq. mm) cast bar. The reduction capacity from the old to new systems represents a nearly 380% increase.

Another example is the SW aluminum mills in Hawesville, Kentucky. The last eight stands of the No. 1 mill reduce a 1.426-sq.-in. (920 sq. mm) section to a 3/8 in. rod. The No. 3 mill uses eight stands to reduce a 3.0 sq. inch (1935 sq. mm) section to a 3/8 in. rod. For the same number of stands, the No. 3 mill uses a feed section 210% bigger than the No. mill to roll the same product.

Several mills have increased the cast bar size (see Fig. 5) with existing equipment due to the stands’ ability to accept a larger bar and increase the reduction per stand. Older examples of cast bar increases include SCR-1, increasing from 2.8 to 5.0 sq. in., and Hitachi, increasing from 5.0 to 10.0 sq. in.

Also, at the No. 3 mill in Kentucky, the cast bar size was increased from 2.0 to 3.25 sq. in. (162%) without changing the rolling stands. A further bar increase to 3.4 in. is planned.

The comparison between a mill commissioned in 1968 and a modern mill designed in 2011 provides an excellent examFig. 7.

Two-roll rolling process The Siemens rolling process incorporates two-rolls for all stands in both the roughing and intermediate mills. The tworoll concept is in practice in hundreds of ferrous and nonferrous installations around the world. The process allows for heavy reductions while maintaining dimensional integrity.

The SCR systems guarantee the final rod will be within one–half the diameter tolerance allowed by ASTM B49. Fig. 8 shows the two-roll conceopt.

Additional benefits are realized in processing and production. Single-point, roll-parting adjustment on a two-roll system is simple and can be made while under load.

Symmetrical roll parting adjustment can also be provided.

Cobble removal is easier as stands can be opened and rolls are easily pulled off line and replaced. The Siemens stands also have larger space between stands compared to those from the other suppliers. This is a benefit when removing cobbles from the pass line as it allows operators to cut the bar in-between the stands and roll out the cobble.

The inventory of rolls needed on hand is significantly lower on two-roll systems compared to others. Rolls can be redressed several times increasing the life of the roll. With the same H-13 tool steel rolls used 30 years ago; mills have gone from 400 tons per groove to over 4,000 tons per groove on the finishing roll. This has been possible due to a combination of factors, including rolling coolants, surface treatments, and statistical analysis of roll life. If the pass width is small enough, multiple grooves can be placed on a roll, which effectively doubles the life of the roll. The significantly improved groove life in addition to the roll life has resulted in dramatically decreased roll inventory today compared to the past.

PRODUCTS DEVO-inspired song calls for a ‘Rip it’ approach to stretch plastic unwrapping On the surface, a 1980s Punk/New Wave band from Ohio and a wire and cable manufacturer from Georgia might not have a lot in common. But DEVO and Southwire Company have come together on a remake of “Whip it,” an iconic song that encourages electrical contractors to “Rip It” good.

Photo by Gary Leftwich, Southwire Company.

The collaboration has resulted in a new video that promotes Southwire’s SIMpull Rip CHIP™ disc, an amazingly simple breakthrough that saves time while eliminating the need to use a knife to remove the stretch wrap placed around wire and cable reels for shipping. The bright green disc is attached to a nylon cord, that, when pulled, in less than 30 seconds easily cuts through the protective stretch wrap.

“It’s an idea we came up with after visiting job sites and talking to our customers. That’s why we wanted to feature some of them in the ‘Rip It’ video,” said Phil Tuggle, senior vice president of marketing and business development of Southwire’s Electrical Division.

VH1 named “Whip It” one of the top 100 songs of the 1980s. DEVO was known for sarcastic humor and postmodernist dress that included yellow jumpsuit stage costumes, black turtlenecks and red stacked “energy caps.”

“The Rip CHIP disc is a fun and effective addition to our packaging that we launched earlier this year as a way to make life easier for contractors on job sites,” said Jack Carlson, president of Southwire’s Electrical Division.

“It wasn’t that far of a reach for the 80s music fans in our company to take ‘Whip It’ and make it ‘Rip It.’” Southwire’s ad agency, Eric Mower + Associates, helped rewrite the lyrics to the iconic song and Southwire lined up original DEVO band members Mark Mothersbaugh

and Gerald Casale to record it earlier this year. Seen in the photo (l-r) are Southwire staffers: Juan Galindo, the engineer who developed the rip cord method; Rhonda Gauthreaux, marketing; Jason Pollard, videographer; and producer, Janice Saari, marketing communications. A number of electrical contractors have starring roles, singing and doing a DEVO-inspired dance in DEVO-style hard hats while demonstrating how to use the Rip CHIP disc.

Complete kitting solution can help installers of spacer cable systems U.S.-based Hendrix Wire & Cable, which supplies complete spacer cable systems that include cable, hardware, spacers and other accessory products, has introduced a kitting solution that it said makes it simpler for installers to use the spacer cable systems.

A press release said that with the company’s kitting solution, the components needed to complete the spacer cable system can be purchased together, assembled at the Hendrix manufacturing plant, and then shipped directly to a job site or a temporary staging area. This offers multiple benefits, it said, noting that as cables are cut to length for the job, this reduces both scrap and installation time as well as short lengths left on the reels at the end of the job, less set ups on reel trailers and less splicing. Another benefit is that warehousing costs can be eliminated along with the time to kit the material at the utilities warehouse, it said.

Hendrix Wire & Cable, an ISO 9001-certified provider of overhead and underground power distribution products, has four operating divisions, one of which is Aerial Cable & Systems, whose benchmark product, spacer cable, reduces weather-related outages and provides options for areas difficult to engineer with standard bare wire systems. The spacer cable is available at 15 kV through 69 kV. Contact: Hendrix Aerial Cable & Systems, overhead@hendrix-wc.com, www.hendrix-wc.com.

cable constructions, including instrumentation, control, variable frequency drive (VFD) and industrial communication and networking products.

A press release said that the company’s continuous armor eliminates the need for conduit and is easier to install and re-route, reducing both the physical cost and the labor cost of installation. The continuous aluminum armor, MC rated for superior crush resistance, is impervious to fluid ingress and is suitable for installation in harsh and hazardous locations, it said. Standard Belden cables that are now available with the continuous armor include FOUNDATION Fieldbus/ PROFIBUS PA (183076F), PROFIBUS DP (183079A), ControlNet Quad Shielded Coax (183092A) and Blue Hose Cable (189463).

Continuous aluminum armor, the release said, is impenetrable because it is applied as a continuous strip of aluminum, that is wrapped around the cable and welded at the seam for impenetrability, and corrugation permits bending without kinking. It noted that Belden now offers three types of MC armor, the other two being aluminum interlocked armor and galvanized steel interlocked armor as well as Belclad corrugated aluminum or steel tape that is sealed to prevent fluid ingress (i.e., chemicals, water and other fluids) into the cable core.

Cable-based antennas are designed to be low-cost solutions for aircraft U.S.-based W. L. Gore & Associates announced that it has developed new lightweight cable-based antennas that improve signal propagation without increasing the amount of hardware required on an airplane.

A press release said that the antennas are ideal for both wide-body and single-aisle passenger aircraft as they provide reliable access to different wireless protocols so passengers can easily connect to in-flight entertainment, Internet servers, and e-mail accounts. The antennas, it said, are easily installed along the length of the cabin ceiling, and with signal propagation occurring every meter along the antenna, passengers are assured reliable access, regardless of their location in the plane. Passenger signals are transmitted via a signal network computer and outside antenna to satellites that connect to the worldwide network, it said, adding that the antennas meet all shock, vibration and fire specifications, including AirBus ABD0031 and FAR Part 25.1359(d).

“Unlike typical broadband technology that requires sepa88 | WIRE JOURNAL INTERNATIONAL

rate hardware for each type of wireless access, the versatile GORE cable-based antenna reduces airline costs because the antenna requires only one set of hardware to service the entire aircraft, regardless of its size,” the release said. The antenna offers a single solution for providing connectivity for a variety of electronic devices, sending and receiving signals in frequencies from 400 megahertz to 6 gigahertz, which makes it compatible with numerous communication standards, including Bluetooth, DECT, DECT2, Global Star, GSM, IRIDIUM Sat, MMS, PDC, TETRA, UMTS, WLAN 802.11 a/b/g, and WiMAX, it said. The antennas, available in lengths of more than 65 meters, require no maintenance for the lifetime of the aircraft, it said.

Laser system can be used to inspect both carbide blanks and tools Italy’s Aeroel Srl has introduced a new family of laser instruments that it said is ideal to check full carbide tools and blanks.

A press release said that the laser instruments, based on the company’s Intelligent Laser Micrometer XLS40, use a special “zero run out” fixture to hold the part, which can be rotated manually or with a motor-driven friction wheel. The application software, it said, can check the effective cutting diameter and the run-out of the tool, no matter the number of cutting edges, which can be either odd or even. When measuring hard metal blanks, such as those used for making dies, it can provide the diameter, the ovality and the straightness, it said.

The instruments, the release said, are perfect for the lab or the workshop as they are simple and cost-effective, and a touch-screen PC can process the measurement data.

Video highlights 4 cold-welders U.K.-based PWM has produced a series of videos demonstrating four of the company’s high-performance cold welders in action that can be viewed at its website.

A press release said that the videos show how PWM’s P1500, P1000, EP500, and HP200 cold welders use the multiple upset technique to create strong, permanent welds on copper and aluminum wire and rod, without heat, flux or fillers. “We have been manufacturing cold welding machines and dies for over 25 years but still find that many wire and cable manufacturers are unfamiliar with the process and the benefits it offers,” said PWM Managing Director Steve Mepsted.

“The videos give manufacturers an opportunity to watch the process from start to finish.

They can see how our user-friendly machines

operate and view the welds produced by our precision-engineered UK-made dies. PWM’s EP500, P1000 and P1500 freestanding rod welders cater for wire/rod sizes from 5 mm to 30 mm. The HP200 portable model, mounted on a trolley, is for wire 2 mm to 6.50 mm diameter.

MEDIA THE ROEBLING LEGACY. This 288-page indexed book by Clifford W. Zink presents a different perspective of

the Roebling legacy. “But it’s all wire,” proclaimed a 1950s Roebling Company brochure about its product line, which included wire rope, copper magnet and electrical wire, screens and hardware cloth, aircord and aircraft strand, flat and braided wire, PC wire and strand, galvanized bridge wire, among others. To maximize quality, the Roeblings started drawing their own wire in the 1850s, rolling bars into rods in the 1870s, and making their own steel in the 1900s. Wire is the binding thread through 125 years of Roebling and American industrial history chronicled in The Roebling Legacy. The price is $75, $50 for WAI members, plus

WASHINGTON ROEBLING'S FATHER: A MEMOIR OF JOHN A. ROEBLING. This 271-page, softcover, indexed book edited by WAI Historian Donald Sayenga and published in 2009 focuses on the legacy of the legendary engineers. Even among legendary engineers, the Roebling family stands out. The brilliant and irascible patriarch John A. Roebling achieved renown as a canal engineer, bridge designer, and innovator of wire rope— a technology that makes possible modern suspension bridges, high-rise elevators, construction cranes, and cable cars. All four of John’s sons inherited the family business, but only the eldest—the reserved, thoughtful Washington—staked an independent claim to fame, most notably for his work on the iconic Brooklyn Bridge.

Between 1893 and 1907, Washington Roebling wrote about his father’s life, character, career, and achievements with candor and intimate family details.

Part biography, part memoir, Washington Roebling’s Father makes available for the first time the text of this remarkable manuscript. Donald Sayenga, an internationally recognized authority on the history of wire rope, has painstakingly transcribed the original manuscript and tracked down annotations for hundreds of people, places, events, and technologies. The price is $55, $45 for WAI members, plus shipping. To purchase, go to wirenet.org and click on The WAI Store.
