The State of Emergency Presents Challenges and Opportunities 紧急情况下的机遇与挑战

f COVID-19 were a new alloy, a new molding system, or an ingenious measuring technology, we would enthusiastically accept the topic and discuss the possible applications in practice. When COVID-19 started on its gruesome path, first in Wuhan and then in the rest of the world, we felt that COVID-19, also called the coronavirus, is an “enemy” that attacks our people, our societies, industry, and economy. Nobody is immune and the antidote is still a long time coming. In the meantime, politics drive public life and with it also our foundry industry, its suppliers and most of the cast buyers markets to zero. It’s a nightmare with science fiction quality that also bind us together, the consequences affect us all! Now that production is shut down and many people are now working from home and only able to accomplish the most necessary tasks, we are given time that we might otherwise not have used. It is the time to think ahead to prepare for what comes after COVID, in life and also in our industry. Politics provides enormous financial support worldwide. This capital has to be used in a targeted manner, for example in new technology, processes, and digitalization. While the first signs of a return to normal life are already visible in China, the rest of the world is still fighting bravely and decisively, because there is life after COVID and the joy that we can meet and exchange personally again. In the meantime, we provide you with the most important information from the world of metal casting in the media at all levels. ■

果Covid-19(新型冠状肺炎病毒)是一种 新合金,一套新造型系统或一项独创的测 量技术,我们将热情地接受它并讨论其在

实践中的应用。 当Covid-19首先在武汉爆发,然后在世界其他地方 开始其可怕的蔓延时,我们认识到Covid-19是攻击我们 的人民、社会、工业和经济的“敌人”。没有人对此免 疫,而疫苗的研发仍需很长一段时间。同时,公众生活 受到了巨大影响,还有我们的铸造业,供应商和大多数 铸件采购业务呈现零增长。Covid-19如科幻小说的噩梦 一样把我们绑在一起,其后果将影响所有人! 虽然目前大部分生产已经停滞,很多人只能在家工 作,完成最必要的任务,我们却得到了原本没有好好利 用的时间:现在是时候思考我们应该为疫情之后的生活 和行业做哪些准备。各国政府已提供了巨大的财政支持, 而且必须有针对性地使用这些资金,例如用于新技术、新 工艺和数字化技术的研发。 目前,中国已经出现了恢复正常生活的迹象,但世界 其他地区仍在勇敢而坚定地抗疫过程中。疫情结束后, 我们仍可以愉快地见面和交流。同时,我们将为您带来 世界各地金属铸造领域的重要信息。 ■ 祝大家身体健康并满怀希望!

Stay healthy and hopeful!

Good luck to you, Thomas Fritsch Editor-in-chief Foundry-Planet GmbH

祝好运! Thomas Fritsch 主编 Foundry-Planet GmbH

Energy and Raw Material Savings in Foundries Through Utilization of Simulation jörg c. sturm, magma giessereitechnologie gmbh, aachen germany

ntroduction

Over the last 30 years casting process simulation tools in foundries have evolved from defect detection and gating development tools to an accepted methodology for the thorough improvement of efficiencies and assurance of robust processes. Naturally, this role of simulation is bases on the trust foundry experts gained in the results of simulation. Therefore, the predictive description of processes is used like a virtual test foundry, where the casting technology is not only calculated once to confirm initial assumptions, but is used to perform parameter and sensitivity studies to detect the impact of important process parameters on the stability of the production process. This establishes the basis for the understanding of important parameters and its impact on energy and material efficiency in a foundry. The following examples depict these connections.

Designing cost reducing castings Weight reduction is the key technology in the automotive and equipment manufacturing industries. 100 kg of weight reduction in a vehicle equate to fuel consumption reduction of 0.2 to 0.4 l/100 km. Over the life cycle of a vehicle, with a total driven distance of 250,000 km, up to 1,000 liters of gasoline or 2.3 metric tons of CO2 can be saved. Also, the equipment manufacturers need to think in lightweight terms. I.e. the increasing weight of planned wind energy nacelles of large offshore wind energy turbines becomes the critical feasibility and success factor. Through the utilization of modern simulation tools it is possible to extract the entire potential of cast materials and their manufacturing processes. Simulation tools today are capable to exactly predict the impact of process parameters onto casting quality. They can be utilized very early in the product development process to reduce weight. The provided information from simulation programs supports not only the designer to find castable and weight optimized designs, but also the foundry engineer to establish a stable and cost effective production [1].

Energy savings through reduction or elimination of trial and error runs Without casting process simulation, many expensive trial runs of the casting process need to be performed after the

绍 在过去三十年间,铸造工艺模拟工具已

经从单纯的缺陷检测和浇流道开发工具进化为一种充分 提高效率和确保稳健工艺的公认的方法。当然,这种模 拟的作用是建立在铸造专家对模拟结果的信任的基础上 的。因此,对工艺预测性的描述就如同一个“虚拟试 验铸造厂”。铸造工艺仿真不仅计算以确认初始假设条 件,还用于进行参数和敏感性研究,以探究重要工艺参 数对生产工艺稳定性的影响。这就为了解重要参数及其 对铸造厂能源和材料效率的影响奠定了基础。下列案例 描述了这些关联。

降低铸件设计成本 减重是汽车和设备制造行业的关键技术。一台车辆减 重100公斤相当于每百公里油耗减少0.2~0.4升。在车 辆寿命期内,按总驾驶里程25万公里计算,可以最高减 少1000升汽油消耗或2.3吨的二氧化碳排放。同样的设 备制造商也需要考虑轻量化条款。例如增加大型海上风 电涡轮机的计划,风能吊舱的重量成为重要的可行性评 估因素。 通过采用现代化模拟工具,可以开发出铸造材料及 其制造工艺的全部潜力。如今模拟工具能准确预测工艺 参数对铸件的影响。可以早在产品开发过程就采用此 工具,以减轻设计产品的重量。模拟软件提供的信息不 仅支持工程师找到可铸性好和重量轻的优化设计,而且 使得铸造工程师能确立稳定和降本增效的生产(工艺) 【1】。 通过减少或消除试错运行来节省能源 如果没有铸造工艺模拟的情况下,在零件设计完结后 需要进行多次成本昂贵的铸造工艺试浇。模拟几乎消除 了通过物理试浇注直到找到最佳工艺配置的过程。铸造

design of the part is finalized. Simulation almost eliminates this process of approaching the optimum process configuration through physical test pours. The foundry expert uses simulation software to establish all process parameters for a robust production prior the production start. Just through the reduction or elimination of test runs, initial raw material and energy savings are realized right away. I.e. an American foundry has reduced the configuration and numbers of test pours so drastically that not only the costs for prototypes by themselves where reduced by US$ 580,000.00 but the elimination of test runs that led to bad castings created additional savings of US$208,000.00 [2].

Introduction of new casting technology

高能源和材料效率的机会得到了行业普遍的承认,但是

The introduction of new casting technology in any foundry is associated with challenges and risks. The chances of increased energy and material efficiency are recognized, but weighted against the production risk and delivery promises. This leads, over and over again, to keeping the old ways of doing things. During the production of complex ductile iron carriers a shrinkage defect was detected only late in the machining process. The first simulation showed the defect and its root cause: the feeding pass to the critical area is cut off prematurely. A change in the riser layout eliminated the defect (Figure 1). Additionally, the necessary changes to the gating system reduced the pouring weight by 13kg and shortened the pouring time by 2.5 s. The realized savings in 13 metric tons of melt per year equals energy savings in the melting process of 12,272 kWh. Another benefit was realized by reducing the riser neck cross section by 25%, leading to reduced riser removal costs. Furthermore, the modified layout leads to a reduction in the solidification time by 11 minutes and, thereby, to an increase in productivity by 15%. The original job was to eliminate the defect. The final solution, based on simulation, lead to significantly reduced production costs [3].

同时也会给生产风险和交货承诺带来风险。这就一再导

Energy and cost savings through riser optimization In one year, the foundry of Heidelberger Druck AG in Amstetten/Germany has evaluated and modified the gating and process technology of 38 currently produced parts with a production volume of 32,000 castings per year. Through this effort 295 metric tons of re-melt with the total weight of 1,300 metric tons were eliminated. Within 18 months Heidelberger Druck saved €100,000.00 per year on material and energy costs [4]. For example, based on simulation results, the gating system of a gearbox housing was changed from 5 to 2 risers. This reduced the pouring weight by 69kg per part or 82 metric tons per year, saving €32.00 per part or €38,000.00 per year. The use of simulation also enabled the foundry to change a 3-on mold for a bearing to a 4-on mold with a simulta32

有工艺参数。 通过减少或消除实际试浇,就能立刻实现省去初次原 材料和能源消耗的目标。例如,一家美国铸造厂大幅度 减少了配置和试浇注次数,不仅降低了样件的成本(58 万美元),而且消除了导致大量铸件质量不良的试浇, 这另外节约了20.8万美元【2】。

引入新的铸造技术 在任何铸造厂引入新铸造技术都面临挑战和风险。提

致了一般厂家在面对这一议题时因循守旧,总是保持以 往的做事方式。 在生产复杂球铁支架铸件的过程中,到了机加工过 程时才发现了缩松缺陷。随后首次模拟便发现了此缺陷 并找到了根源:通向关键区域的补缩通道被提前阻断。 对冒口设置方案进行调整后便消除了这一缺陷(图1) 。此外,对浇注系统的必要修改使得浇注重量减少了13 公斤,浇注时间缩短了2.5秒。这样一来每年实现了节 约金属液13吨,相当于在熔炼过程中减少能耗12272千 瓦时。通过缩小冒口颈横截面积25%实现另一效益(减 少冒口清理费用)。而且,修改后的工艺设置方案让凝 固时间减少了11分钟,并进而使得生产率增加了15%。 原先的目的是消除缩孔缺陷。基于模拟的最终方案使得 生产成本大幅度降低【3】。

通过优化冒口节约能源和降低成本 在一年的时间里,德国阿姆施泰滕的Heidelberger Druck AG铸造厂对目前生产的38种铸件(年产铸件量 32000件)的浇冒口系统和工艺技术进行了评估和修 改。通过这一努力,在总重量达1300吨的基础上避免 了295吨回炉料。 在前18个月内,Heidelberger Druck每年在材料和 能源费用上节约10万欧元【4】 其中的一个齿轮,基于模拟结果,浇冒系统的冒口 从5个修改为2个。每件减少浇注重量69公斤或每年减 少82公吨,相当于节省每件32欧元或每年38000欧元 的成本。 采用模拟使得铸造厂还能将一模3件改为一模4件,

neous reduction in the number of risers. The casting yield increased by 53%, reducing the cost per part by €2.18. Quality supported by simulation avoids energy intensive scrap John Deere, Moline/IL, USA, was able to reduce the scrap rate of a gray iron part from 10.3% to 1.4% by modifying its design and gating system, leading to annual savings of US$66,936.00. At the same time, the casting yield was increased from 58% to 64% through the consequent utilization of casting process simulation. This equals additional savings of $66,600.00 per year. The total amount of iron necessary was reduced by 195.6 metric tons leading to 274 molds more available on a molding line running at full capacity. This optimization also provides energy savings of 160,000 kWh per year. If simulation would have been used at an earlier stage, the foundry claimed an additional savings potential of US$140,000.00 in the first year of production and the avoidance of casting design and pattern change costs of US$120,000.00 [5].

Energy and cost savings in aluminum permanent mold casting processes

金属型铸铝工艺的节能降耗

The potential for energy savings in mass produced castings is comparatively high, due to the leverage provided by the huge number of parts. Through pattern layout changes and casting process modifications, only possible by utilizing casting process simulation, the aluminum foundry EBCC, Wroclaw/Poland, achieved more than €100,000.00 in cost savings in their production of brake calipers [8]. The main factors leading to this success were the reduction of burn-off during melting (about €25,000.00 per year), melting energy savings (about €45,000.00 per year), and reduced cycle time with resulting lower wear of the permanent mold lead to a reduction in the number of needed replacement molds (€35,000.00 per year). Obviously, this reduction in cycle time also lead to an increased productivity (Figures 2) [6].

提高产品质量,避免能耗密集型废品 美国伊利诺斯州的John Deere, Moline通过修改其设 计和浇冒口系统能将灰铸铁废品率从10.3%降低到1.4% ,年节约成本66,936.00美元。与此同时,通过随后采 用铸造工艺模拟使得铸造出品率从58%增加到64%。这 相当于每年另外节约66,600.00美元。需要铁水总量降 低195,6吨,使得在满负荷生产时造型生产线上可再提 供274个铸型。此优化每年还可以节约能源160000千瓦 时。如果在早期就采用这一模拟技术,铸造厂声称在第 一年生产时有另外节约140,000.00美元的潜力,并可免 去铸件设计和模型修改费用120,000.00美元【5】。

由于大批量铸件生产提供的杠杆作用,大批量生产铸 件节能的潜力相对较高。 通过模型布置方案修改和铸造工艺改进(只有通过采 用铸造工艺模拟才有可能),波兰弗罗茨瓦夫铝铸造厂 EBCC在其制动钳生产中已经获得节约成本10万欧元以 上的效益【8】。引起这一成功的主要因素就是减少了 熔炼过程中的损耗(每年大约25000欧元),熔炼节电 (大约每年45000欧元)和降低循环时间,据此造成金 属型损耗较少,导致需要更换铸型数减少(每年35000 欧元)。很明显,减少循环时间也会提高生产率(图2 )【6】。

one. The condition was not to negatively impact the casting quality. A comprehensive virtual parameter study (DoE) was conducted using casting process simulation to evaluate the impact of several process parameters and gating designs (Figure 3). The software allows for the immediate comparison of all calculated trial runs and depicts the best solutions (Figure 4). The result was a reduction of runner volume by 25%, which lead to 12% less material used per shot. At the same time, the optimized cooling line design, in combination with the lower pouring weight, lead to a cycle time reduction of 8% [7].

The change from a single to a multi-cavity die requires the change of the runner design, which often can lead to quality differences between the castings in the die. This problem is especially present in dies using a non-symmetrical gating system, where the separate cavities are fed by individual runners. Designing a flow-dependent shape of the runners, the filling characteristics of a single-cavity die where successfully transferred to a dual-cavity die. The high quality level achieved in the single-cavity die, were successfully transferred to a dual-cavity setup by utilizing automatic optimization. The production risk was thereby significantly reduced through the use of casting process simulation and the foundry benefited immediately from the implementation of the new layout [9].

Casting Process Simulation – from competitive advantage to technology saving the environment The provided examples documenting that if casting process simulation is utilized throughout the entire casting process, a 10% efficiency improvement is easily accomplishable. In connection with the current discussion relating to energy efficiency and related protection of the environment, the displayed potential savings in energy and materials, achievable through the utilization of casting process simulation, make the use of simulation in foundries mandatory.

关于铝铸件焊接的建议 David Weiss, Mike Gwyn, Keith Sturgill

I

n-process weld reworked parts can meet the requirements of aerospace, military and commercial structural specifications when reworked with proper capability. But since it is expensive, foundries should try to minimize welding on castings to the extent possible. In most aluminum foundries, there is an area in the corner of the building that no one wants to talk about: the welding area. Sometimes this is used for legitimate activities, like welding a plug into a core support hole, but it is often used to repair defects in castings so they meet dimensional or other quality specifications. Neither customers nor foundry management are completely comfortable with this since the mantra is to make it right the first time. Nonetheless, complicated designs, low volume requirements or cost pressures sometimes make it necessary to use weld rework to salvage castings. Castings are susceptible to having small surface imperfec-

tions such as inclusion pits, gas microporosity, cold laps, misrun edges, or dents from handling damage that are cosmetically unappealing or non-compliant. In-process weld rework of castings is a routine casting finishing activity that is used to mend such casting surface imperfections across almost all alloy families and mold cavity-making processes. A casting that has been welded, blended and heat treated and has passed all drawing specified inspections will be dimensionally, physically, chemically, metallurgically, and structurally compliant to drawing requirements. Therefore, specifications to limit or document in-process weld rework of surface imperfections are rarely noted in commercial castings. Even among military and aerospace castings, in-process weld rework for surface imperfections is not always limited by specifications. In all cases, minor surface imperfections can be ground away up to 1.5mm depth and blended. One of the earliest papers on the subject by Anderson and Boyd was published in the 1924 edition of the Transactions of the American Foundrymen’s Association. They report, “With simple castings, the loss due to wasters may be quite low, say 4-7 percent, but in complicated castings, like crankcase upper halves for 8-cylinder motor cars, it may be as much as 20-25 percent on the average. Of these losses, some 50 percent is reclaimed by soldering and welding.” They go on to say, “It is quite obvious that a welded joint will not possess the strength of the original casting.” Fortunately, the scrap and salvage rate are not as high as they were in 1924 and certainly the comment about the strength of the welded joint is no longer true, although believed by many.

孔、微缩孔、冷隔、浇不足或由于外观上不美观或不 合规而造成的凹痕。铸件的焊接返修是常规的铸件后 处理操作,可用于修补几乎所有合金类型和造型过程 中出现的铸件表面缺陷。 经过焊接、焊补和热处理并通过所有图纸设计的特 定检查后,铸件在尺寸、力学性能、化学成份、冶金 性能和结构上均应符合图纸设计要求。因此,在商用 铸件中很少有对表面缺陷焊接返工的限制规定或程序 文件。即使在军工和航空航天铸件中,针对表面缺陷 铸件的焊接返修也不总是采取限制规定。在所有情况 下,较小的表面缺陷都可以研磨至1.5mm的深度并得 到焊补。 针对该问题,Anderson和Boyd联合撰写的一篇文 章早在1924年出版的《美国铸造协会论文集》上发 表。文章里写到:“在简易铸件中,因废品造成的损 耗可能很小,为4-7%;但在复杂铸件中,如8缸汽 车曲轴箱上盖,平均废品率可能高达20-25%。在这 些废品中,约有50%可以通过钎焊和焊补挽救。”此 外,文章还提到“很明显,焊接接缝不具备原始铸件 的强度。” 幸运的是,目前的废品率和补救率没有1924年的 对焊接接缝强度的认识是不符合实际的。

AMS 2175 In-process weld rework is also performed on surface and near-surface discontinuities. These discontinuities are typically harmful to the structural performance of a casting. They are hot tears (pre-existing cracks from the nature of the alloy, mold cavity geometry, and/or the mold cavity material),

cracks from heat treating, and near-surface voids revealed by radiography or ultrasound. For commercial castings, the extent of discontinuities is typically classified by radiographic standards. For military and aerospace castings, severity of cast component service is classified (Classes 1 through 4) and surface and/or internal integrity is specified by AMS 2175, Grades A through D. Classes require different levels of nondestructive testing, and Grades directly affect allowable stress for cyclic life. AMS 2175 covers almost all casting processes and the full range of casting alloys, so it is also adopted as a commercial standard for safety-critical castings. Importantly, AMS 2175 is silent regarding in-process weld rework, only specifying the extent of imperfection in Grades A through D as “graded” in visual, radiographic, magnetic particle, or die penetrant inspection. This is inspection after all as-cast processes are complete, including final heat treatment. Logically, castings that are classified 1 or 2 should have carefully defined specifications for in-process weld rework. Such specifications and/or drawing notes define the weld processes, weld filler alloys, pre-weld surface preparations, welder qualifications, post-weld surface blending, and pre-weld and/or post-weld heat treatment. The manufacturing capability of these specifications to sustain class and grade’s strain life properties has been established by data developed by OEMs, defense primes, and metalcasters. Some data has been published but much is considered proprietary and not generally available.

断点通常对铸件的结构性能有影响。它们是热裂(由 于合金的特性、型腔几何形状和/或型腔材料已经存在 的裂纹)、热处理产生的裂纹以及射线照相或超声波 检测出的近表面空隙。对于商用铸件,间断点的严重 程度通常通过射线照相标准进行分类。 对于军工和航空航天铸件的缺陷程度进行了分类(1-4 类),并且铸件表面和/或内部完整性由AMS 2175 (A-D级)确定。这些类别要求不同等级的无损检 测,这些差别会直接影响使用周期的容许应力。AMS 2175涵盖了几乎所有铸造工艺以及合金,因此它也被 用作与铸件安全性密切相关的商用技术标准。 重要的是,AMS 2175不限制铸件的焊接返工,仅在 可视化、射线照相、磁粉检测或模具渗透检查中将 A-D级的缺陷进行分级。这是所有铸造过程(包括最 终热处理)完成后的检查。 从逻辑上讲,分类为1或2的铸件应对焊接返工有明 确规定。此类规范或图纸说明对焊接工艺、焊缝合 金、预焊接表面处理、焊工资格、焊后表面处理以及 焊前和/或焊后热处理下了定义。这些可以维持铸件类 别和等级应力特性的制造能力已经由OEM、国防部门 和金属铸造企业所开发的数据建立起来。一些数据已 经发布,但是很多数据被认为是专有的,一般无法获 得。

AMS-A-21180 The most limiting specifications, typically AMS-A21180 and its ASTM counterparts, may call out “no-weld zones” or “in-process weld rework only upon written permission of the purchaser.” Maps may be required showing location, size, and depth of welds. No structural component of any kind and, therefore, no structural casting, is critically stressed all over. This scenario, best represented by specification AMS-A-21180, should be applied only to casting surfaces that really are critically stressed. Other specifications give direction on repair welding of aluminum castings that are sometimes used. AMS 2694 defines requirements for in-process corrections of discontinuities by manual welding. Several specifications deal specifically with welding of aerospace structures such as AWS 17.1 and FAA Advisory Circular No. 33-6 on weld repair of aluminum crankcases and cylinders.

Process for Weld Rework Welding is another molten metal process. The correct manufacturing steps can be defined, and the details will depend on the specific defect. T.J. Bosworth of Boeing wrote an excellent paper on weld rework of aluminum castings, defining key steps to achieve high quality welds. Those steps can be summarized as follows: • Prepare the weld area. Remove the defect and remove the oxide layer with a brush or solvent. • Preheat before welding. Preheat generally improves welding results. The usual range is 212–572F (100– 300C). Generally, aluminum alloys containing copper are welded at the higher end of that temperature. Castings will usually be welded in the as-cast condition but sometimes defects will not be uncovered until after heat treatment, so they are welded in the T6 or T7 condition. In 200 series alloys or for castings that require extensive repairs, it is recommended that T6 or T7 tempered castings be annealed before welding to avoid cracking. • Use weld rod that matches the chemistry of the casting or an approved substitute. Chemistry control in welding is as important as it is in melting for casting. Use of a general-purpose rod across all alloy systems will result in reduction of mechanical properties and color mismatches even though welding may be “easier.” • After welding, the weld needs to be dressed back to part contour. A common complaint of customers about welded castings is the weld has not been cleaned or there is a color difference. If a weld repair is noticeable with casual viewing, the repair has not been done correctly. • Heat treat after welding. Even though a good weld will have little porosity and a fine structure, mechanical properties will not be met if the repaired casting is not heat treated to the specification. Heat treatment will also eliminate the residual stress that may have been caused by the welding process.

AMS-A-21180 最具限制性的规范(通常是AMS-A-21180及其 ASTM的相应规范)可能指出“不接受焊接”或“ 只有在采购商书面许可下,才可以进行焊接返工” 。可能需要指定焊接位置、大小和深度的图纸。因 此,不存在任何类型的结构部件受到全面的严重应 力影响。AMS-A-21180作为最佳规范,这种情况 应仅应用于确实受到严重应力影响的铸件表面。 其他规范为不常使用的铝铸件的修补焊接提供了指 导。AMS 2694定义了通过手工焊接对在制铸件的 间断点进行补修。还有几个规范专门针对航空航天 结构件的焊接,例如AWS 17.1和FAA咨询通告第 33-6号文件针对有关铝曲轴箱和气缸的焊接修复。

焊接返修工艺 焊接是另一种熔融金属工艺,可以对工艺步骤做出 恰当的规定,并且工艺细节将取决于特定的缺陷。 波音公司的T.J. Bosworth写了一篇出色的论文,介 绍了铝铸件的返工焊接,确定了实现高质量焊接的 关键步骤。 这些步骤可以总结为: • 焊接区域准备工作。去除缺陷,用刷子或溶剂去除 氧化层。 • 焊接前预热。预热通常可以改善焊接效果。范围通 常是212–572F(100–300℃)。一般情况下,含 铜的铝合金要在较高温度下焊接。铸件通常在铸态 下焊接,但有时直到热处理后才发现缺陷,因此它 们在T6或T7条件下焊接。在200系列合金或需要大 范围维修的铸件中,建议在焊接前对T6或T7回火 的铸件进行退火处理,避免开裂。 • 使用与铸件化学成分相匹配的焊条或经认可的替代 品。焊接中的化学控制与铸件中的化学控制一样重 要。即使焊接“更容易”,在所有合金系统中使用 通用焊条会降低力学性能、使颜色不匹配。 • 焊接后,需要将焊缝修整至零件轮廓。客户对焊接 铸件的普遍抱怨是,焊缝尚未清洗或存在色差。如 果偶然观察到很明显的焊缝,则表示修复操作不正 确。 • 焊接后的热处理。尽管良好的焊缝也存在很少量的 气孔,但如果未对修补后的铸件进行热处理,就无 法满足良好的组织和力学性能的要求。热处理还将 消除可能在焊接中产生的残余应力。

Property Studies on Repaired Castings In an early study of the efficiency of repair welding of aluminum casting, it was reported that cast A357-T6 and A201-T7 material which had been welded to a depth of 50% of the wall thickness were re-heat treated and tested for notched fatigue, fracture toughness and tensile properties. In comparison with the properties of the parent material, the tensile properties of the welded material of both A357-T6 and A201-T7 were very similar, and the notched fatigue and fracture toughness of the welded A201-T7 were better than the parent material. The fatigue properties from welded A357-T6 material showed a slight degradation in comparison with those of the parent material after 500,000 cycles, and the fracture toughness properties of welded A357-T6 were similar to the toughness of the parent material. Recent work showed that properly accomplished in-process weld rework had essentially no effect on the static and dynamic tensile properties of E357-T6 sand castings. This work was done with sand cast plate, with a defect machined in to duplicate either a full weld or a half weld repair. Figure 1 illustrates that concept, and Table 1 shows the summary tensile data. The fatigue data for the three types of specimens (Figure 2) are very similar to each other. However, regression suggest that the cast (no weld) specimens are slightly better (longer life) at high stress levels, the full weld and no weld specimens are about the same life at low stress levels, and the half weld samples demonstrated the longest fatigue life at low stress levels. This suggests either a difference in the microstructure, the geometry of any pores present, or the number of pores present in the original cast structure of the metal in the weld zone.

Recommendations From a technical standpoint, in-process weld reworked parts can meet the requirements of aerospace, military, and commercial structural specifications when re-worked with proper capability. Foundries should try to minimize welding on castings to the extent possible, since it is expensive. End-users should not prohibit welding on castings but should ask the foundry to demonstrate capability to meet the metallurgical specifications of the drawing. Foundries should ensure all personnel who weld castings are capable of meeting part requirements and have adequate training to do so consistently. This article is an adaptation of Paper 19-014 that was presented at the 2019 Metalcasting Congress in Atlanta. ■

修复铸件的特性研究 据报道,在对铝铸件修复焊接效能的早期研究中, 对已焊接至壁厚50%的铸件A357-T6和A201-T7 进行了重新热处理并测试了缺口疲劳、断裂韧性和 拉伸性能。与初始材料的性能相比,A357-T6和 A201-T7焊接材料的拉伸性能非常相似,经焊接的 A201-T7的缺口疲劳性能和断裂韧性比初始材料更 好。与经过50万次循环后的初始材料相比,焊接 A357-T6材料的疲劳性能略有下降,其断裂韧性与 初始材料相似。 最近的研究表明,正确的返工焊接操作对E357-T6 砂铸件的静态和动态拉伸性能基本没有影响。这项 工作是用砂铸板完成的,对缺陷可重复进行全焊缝 或半焊缝修复。图1对此做了解释,表1为拉伸性能 的总结数据。 3种样品的疲劳数据(图2)彼此非常相似。但 是,回归测试表明,无焊缝铸件试样在高应力水平 下的疲劳寿命更长,全焊缝和无焊缝试样在低应力 水平下的疲劳寿命大致相同,半焊缝试样在低应力 水平下显示出最长的疲劳寿命。这表明,在焊接区 域中,任何存在的气孔的微观结构和几何形状有所 不同,或者,金属原始结构中的气孔数量有所不 同。

建议 从技术的角度来看,当进行恰当的返修加工后,焊 接返工件可以满足航空航天、军工和商业铸件的结 构要求。 但因为价格昂贵,铸造企业应尽量减少对铸件的 焊接。 最终用户不应禁止在铸件上进行焊接,而应要求 铸造企业证明其具有满足设计图纸冶金技术要求的 能力。 铸造企业应确保所有焊接人员都具备满足零件要求 的能力并接受过一致性操作培训。 文章改编自在亚特兰大举办的2019年美国铸造大会 上发表的论文(19-014)。 ■

T

he benefits of adding finely divided bituminous coal, commonly known as seacoal, or other carbon rich additives to clay-bonded molding sands have been well established by the foundry industry to generate air emissions. Hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) are generated and released during the metalcasting process because of the pyrolysis of the carbonaceous additives in the molding sand. In general, organic substances produce volatile gases and deposit a solid residue enriched in carbon after pyrolysis. This pyrolysis of carbon containing materials has generally been accepted as serving several essential functions in green sand castings as summarized in publications as far back as 1980. The generation of volatile gases from the carbonaceous material promotes a reducing environment in the mold cavity helping to inhibit the oxidation of the liquid metal. The pressure generated by the volatile gases, in addition to the

造行业由于工艺的需要,粘土砂造型中添加 破碎磨细的烟煤,也就是煤粉,或其他富含 碳的添加剂,但是生产过程中会排放气体。

由于型砂中含碳添加剂的热解作用,其在铸造过程中会 生成并释放有害的大气污染物(HAPs)和挥发性有机 化合物(VOCs)。 通常情况下,有机物产生挥发性气体并在热解后沉 积出富含碳的固体残留物。如早在1980年的出版物中 所概述的那样,含碳材料的这种热解作用在粘土型砂铸 件中具有几个基本功能,已得到普遍认可。含碳材料产 生的挥发性气体使型腔保持还原性气氛,有助于抑制金 属液的氧化。除热解过程中沉积的富碳残留物外,挥 发性气体产生的压力还有助于防止金属液渗透并有助于

carbon rich residue deposited during pyrolysis, helps resist metal penetration and promote good casting finish while aiding in the peel of the solidified casting from the sand mold. The gases that are evolved from the carbonaceous material exposed to high temperatures in the sand mold contain VOCs and HAPs and have been shown to be major contributors to overall foundry air emissions. With the introduction of the Clean Air Act in 1990, the foundry industry has worked to reduce the emissions impact from metalcasting processes. One such approach to emissions reduction that has been adopted with some success has been replacement of seacoal with lower emitting substitutes such as causticized lignite. Studies have been conducted to show the potential reduction of emissions as a result of this replacement. One such study showed that substitution of seacoal with causticized lignite showed a substantial reduction in VOCs and HAPs while maintaining good casting finish on the test pieces. Since that particular study, many foundries have adopted this approach by including some amount of causticized lignite in their bentonite pre-mix. Foundries can monitor their VOCs and HAPs emissions through sampling and testing of their waste gases through approved sampling and testing methods typically known as stack testing. Pyrolyzer Gas Chromatography Mass Spectrometry (pyrolyzer/GC-MS) analytical technique studied here can potentially serve as a tool to predict emissions response from the green sand component of the foundry. This could address a need in the foundry industry as it has been shown in other studies that traditional laboratory tests such as determination of volatile combustible matter (VCM) and loss on ignition (LOI) are not statistically significant factors in predicting foundry emissions from green sand. Lab pyrolysis testing may prove to be a more significant predictor of emissions generated from green sands, although further studies are required to determine any correlations. 42

形成良好的铸件表面,同时有助于从砂型中分离凝固 的铸件。在砂型中暴露于高温碳质材料中产生的气体 含有有害大气污染物(HAPs)和挥发性有机化合物 (VOCs),并且已表明它们是铸造企业有害气体总 排放物的主要组成。 随着1990年《清洁空气法》的出台,铸造业一直 致力于减小金属铸造过程中的排放影响。一种成功的 方法是,用排放量较低的替代品(如苛化褐煤)代替 煤粉。研究已表明这种替代法可能减少排放,用苛化 褐煤代替煤粉可显著降低VOCs和HAPs,同时在试件 上保持了良好的光洁度。自从进行了这项特殊研究以 来,许多铸造企业已采用这种方法,在膨润土预混合 物中加入一定量的苛化褐煤。 铸造企业可以通过经过认证的采样和测试方法, 即常用的排放口测试,对废气进行采样和测试,来监 控其VOCs和HAPs排放。本文所研究的热解气体色谱 质谱法(pyrolyzer/GC-MS)分析法可以用作预测 铸造厂粘土砂气体排放值的工具。这可能满足了铸造 行业的需求,正如其他研究所表明的,传统的实验室 测试,例如挥发性可燃物(VCM)的测定和烧损量 (LOI)并不是预测粘土砂大气排放值在统计意义上 的重要因素。尽管还需进一步研究以确定是否存在相 关性,但实验室热解测试可能被证明是粘土砂产生排 放的更重要的预测指标。

Seacoal of Kentucky origin was used for this study. This seacoal is currently used by many foundries throughout the U.S. Causticized lignite is a manufactured product. Commercially available causticized lignite was used for this testing. A experimental design (DOE) was conducted to estimate any main effects and/or interaction effects that exist between the amount of seacoal and the amount of causticized lignite a bentonite pre-blends used to prepare molding sands. The test matrix was replicated at least three times. The results of the experiment were entered in the commercial DOE software and two-way ANOVA was performed at a 95% confidence level. The statistical software advises that the model overall is statistically significant based on the F-values and p-values. The F-value for each term was high, indicating the variation between the groups in the design was much higher than the variation within the groups of the design. When the F value is larger than a predetermined F value based on the degrees of freedom for the terms between the groups and within the group, the term is considered significant. The interaction term AxB was removed from the model because it was not significant. The correlation coefficient for the model (R2) was 0.965, indicating the model can account for approximately 96% of the variation seen in the total emissions response as a function of the percentage of seacoal and causticized lignite added to the pre-blend. The ANOVA results for each of the nine individual compounds showed statistically significant models as well and indicated both % seacoal and % causticized lignite in the pre-blend are main factors while the interaction effect between seacoal and causticized lignite was not significant in predicting the variation in the total emissions response. The R2 values for the individual compounds ranged for 0.822 to 0.986. ANOVA analysis for the mechanical green sand test responses results did not show any statistically relevant relationships between any of the responses and factors. In each case, the F-test values were very

品。该测试使用了商业用苛化褐煤。 为了预测煤粉量与苛化褐煤之间存在的主要影响 和/或相互作用,进行了实验设计(DOE)。苛化褐煤 预混合用于膨润土中。 测试矩阵至少进行了3次重复测试。实验结果输 入到商用实验设计软件中,进行二因子方差分析, 可信度为95%。统计软件建议,基于F值和p值,该 模型总体上具有统计学意义。每个实验值的F值都 很高,这表明设计中各组之间的差异远高于设计中 各组内部的差异。 基于各组之间以及各组内部实验值的自由度, 当F值大于预定F值时,该实验值被认为是有效的。 由于交互项AxB不重要,因此将其从模型中删除。 该模型的相关系数(R2)为0.965,表明该模型可 占总排放反应中所观察到的变化的约96%,该变 化是添加到预混物中的煤粉和苛化褐煤百分比的函 数。9种单独化合物中的每一种的方差分析结果也 显示出统计学上的重要模型,并且表明预混物中的 煤粉和苛化褐煤的百分比均是主要因素,而煤粉与 苛化褐煤之间的相互影响对预测总排放反应中碳氢 化合物的变化并不明显。各个化合物的R2值范围为 0.822至0.986。 粘土砂试验的力学性能反应结果的方差分析未 显示出反应和因素之间的统计关系。在每种情况 下,F测试值都很低,表明实验设计中各组之间的 方差与各组内观察到的方差没有显著差异。p值也 都非常高,大于0.05,表明数据的变化不能由这些 因素进行充分解释。这并不出乎意料,因为研究中 使用了钠和钙膨润土比例不同的商业配方,并且已 知该研究可以更好地预测某些力学性能。

low indicating the variance between the groups in the experimental design did not differ significantly from the variance observed within the groups. The p-values were also all very high, above 0.05, indicating the variation in data was not adequately explained by the factors. This was not unexpected since commercial formulations with varying ratios of sodium and calcium bentonite was used for this study and this is known to be more predictive of certain mechanical properties The coded prediction equation generated from the statistical analysis of the variance is shown as Equation 1.

由方差统计分析生成编码预测方程如方程式1 所示。

Total Emissions coded (ppm)=37.85 x Seacoal %+10.37 x Causticized Lignite %+199.0

为4.1。

The coefficient for % seacoal, 37.85, is 3.6 times larger than the coefficient for % causticized lignite, 10.37, indicating that in this model seacoal will contribute 3.6 times as much to emissions as an equivalent amount of causticized lignite on the coded scale. This was in good agreement with the results obtained when comparing the total emissions generated from the seacoal or the causticized lignite in the absence of other materials. That ratio was approximately 4.1 as calculated from the data. The uncoded prediction equation shown here indicates that a substitution of 3-5% of the seacoal with causticized lignite could yield a potential reduction in emissions between 9-15%.

编码的总排放量(ppm)= 37.85x煤 粉%+10.37x苛化褐煤%+199.0 煤粉系数(37.85)是苛化褐煤系数(10.37)的 3.6倍,表明在此模型中,计算编码的数值,煤粉在 排放量中的占比是等量苛化褐煤的3.6倍。这与在没 有其它添加物的情况下,煤粉或苛化褐煤产生的总 排放量的比例结果非常吻合。根据计算,该比率约 此处显示的未经编码的预测方程式表明,用苛 化褐煤代替3-5%的煤粉可潜在减少9-15%的排放 量。 预计总排放量(ppm)=8.90x煤粉%+2.30x苛 化褐煤%-0.60 实验设计软件生成的残差分析的正态图进一步证 实了模型的重要性。方程式2用于预测其他实验室 制备粘土砂的排放量,并将其与测量值进行比较( 图1)。对于7个确认测试批次中的5个,模型预测 值在测量值的5%以内。

Total Emissions predicted (ppm)=8.90 x Seacoal %+2.30 x Causticized Lignite %-0.60 The normal plot of the residual analysis generated by the DOE software provides further confirmation of the significance of the model. Equation 2 was used to predict the emissions for additional lab-prepared green sands which were compared to the measured values (Fig. 1). The model predictions were within 5% of the measured value for five of the seven confirmation test batches. Additionally, Equation 2 was applied to predict the emissions results of 10 commercial foundry green sands available in the laboratory (Fig. 2). The agreement between predicted and actual values for commercial green sands was lower than with the labprepared samples. This was somewhat expected. Many other variables that can contribute to green sand emissions were not addressed in the experimental design, such as core sand concentration, additional carbonaceous sources (e.g. gilsonite), parting sprays, and mold coatings and washes.

Conclusion The pyrolyzer/GC-MS analytical technique is an effective indicator in predicting the potential emissions output from the seacoal and causticized lignite component in a bentonite-based pre-blend. The DOE methodology used in this study indicated both seacoal and causticized lignite are main factors in modeling the total emissions generated from the green sand sample, but no significant interaction effect was observed. The emissions results from the experimental design support other studies that showed a replacement of seacoal with causticized lignite has the potential to reduce foundry emissions. The results of this study suggest that a replacement of 3-5% seacoal with causticized lignite in bentonite-based pre-blend could translate into a reduction in total emissions between 9-15%. The model generated from the statistical analysis of the emissions results indicates it is statistically significant and confirmation tests with lab prepared green sands showed reasonable agreement between predicted and actual values. The model developed in this experiment was less robust for the prediction of emissions of commercial green sands. This was not unexpected given that other factors contribute to green sand emissions, such as resin coated core sands. An additional DOE incorporating organically bonded resin sand additions to green sand mixtures will be considered to improve the predictive capability of the model. Another possible approach would be to evaluate commercial foundry stack testing results against emission results from foundry green sand in the laboratory to determine if any trends can be observed over time. ■

此外,方程式2用于预测实验室中可用的10种商业 用铸造湿型砂的排放结果(图2)。商业粘土砂的预 测值与实际值之间的一致性低于实验室制备的样品。 这在某种程度上是意料之中的。实验设计中还有许多 其他可能导致粘土砂排放的变量尚未涉及,例如芯砂 浓度、其他含碳源(如沥青)、分型喷砂、模具涂层 和清洗剂。

结论 热解气体色谱质谱法分析技术是预测基于膨润土 的预混料中煤粉和苛化褐煤成分的潜在排放量的有效 指标。 本研究中使用的实验设计方法表明,煤粉和苛化褐 煤都是模拟粘土砂样品产生的总排放量的主要因素, 但未观察到明显的相互作用。 实验设计的排放结果支持其他研究,这些研究表明 用苛化褐煤代替煤粉有可能减少铸造厂的排放。这项 研究的结果表明,在膨润土基预混料中用苛化褐煤代 替3-5%的煤粉可以将总排放量减少9-15%。 通过对排放结果进行统计分析生成的模型表明,该 模型具有统计学意义;使用实验室制备的粘土砂进行 的确认测试显示,预测值与实际值之间存在合理的一 致性。 该实验中开发的模型对于预测商用粘土砂的排放不 够稳健。这并不意外,因为要考虑到其他因素会产生 排放,例如树脂芯砂。在另外一项实验设计中,将有 机粘结树脂砂加入到粘土砂混合物中,用以提高模型 的预测能力。 另一种可能的方法是,根据实验室中粘土砂的排放 结果评估实际铸造测试结果,以确定随时间推移是否 可以观察到任何变化趋势。 ■ 文章改编自在亚特兰大举办的2019年美国铸造大会上发表 的论文(19-082)。

Marking System Increases Efficiency 标记系统提高效率 ITT Goulds Pumps Inc. (Seneca Falls, New York) needed to replace its aging pattern labeling equipment. This sand mold foundry manufactures industrial pumps used by customers in the oil, gas, mining, power generation, chemical, pulp/paper, and general industrial markets. Like many foundry operations, the resources and processes required for pattern labeling are being evaluated for the equipment needed and for their ease of use and manpower investment. The manufacturer depends on pattern labels to provide a mechanism for process control and quality tracking. Tracking piece quality throughout the process provides information that allows them to track operations and limit batch sizes if issues arise. In many foundries, the equipment used to apply the date codes, heat numbers and other traceable identification elements applied to patterns is aging badly. The preferred equipment, used for decades, requires operators to rotate a wheel engraved with a given character size, one character at a time. Rotating the heavy wheel to make multi-character labels is cumbersome and time-consuming. Additional character sizes meant the investment in duplicate systems to meet the various size requirements because the different-sized character sets and base equipment are not interchangeable. If multiple labels of the same legend are required, the process repeats. Manufacturers requiring high levels of traceability, such as automotive and aerospace, often have significant investments of time and equipment. These resources are needed to make all the additional labels used to identify line number, operator ID, or other factors so they can minimize batch size if a recall occurs. The manufacturers that built these systems in the past have reduced available character sizes and don’t make spare parts for some systems. In addition, some marking companies have either shifted their focus to other, newer technologies where market size justifies production/development costs, or simply shut down. Many foundries are forced to hunt for second-hand parts online or use letters and numbers that can be pinned onto patterns. Parts bought online are hard to find and may be a shortlived solution when purchased used. Pinned on characters work but are not cost-effective. Their application and removal is tedious and time consuming, and the characters cannot always be reused. A shrinking workforce, needed

ITT古尔兹泵业有限公司(纽约州塞内卡福尔 斯)需要更换其老化的铸件标识设备。这家砂型 铸造公司为石油、天然气、采矿、发电、化工、纸 浆/造纸和通用机械客户生产工业泵。像大部分铸 造厂一样,在更换铸件标识设备前,要对其所需资 源和工艺进行评估,了解其是否好用及人力方面的 投入。生产企业依靠铸件标识机制提供过程控制和 质量跟踪。在生产过程中跟踪影响铸件质量的相关 信息,跟踪生产流程并在发现问题后准确识别其批 次和数量。 许多铸造厂是将日期代码、批次编号和其他可追 溯的识别元素作为铸件标识,所使用设备已经严重 老化。有些设备已使用了数十年,需要操作员旋转 标签轮,轮上刻有给定尺寸的字符,1次旋转1个字 符。旋转轮很重,制作多字符标识既麻烦又费时。 由于不同大小的字符集和基本设备不可互换,因此 额外的字符意味着要增加多个系统,以满足各种标 识字符要求。如果需要相同规格的多个标识,则重 复该过程。如果生产企业对可追溯性的需求高,例 如汽车和航空航天企业,往往需要更多时间,投入 更多设备。需要投入这些资源来制作用于识别生产 线编号、操作员ID或其他因素的所有标识,以便在 发生产品召回时能够将批次规模最小化。 过去,生产这些系统的制造商减少了可用的字符 大小,并且不为某些系统提供备件。此外,一些标 记公司已经将发展重点转移到其他方面,比如市场 规模证明生产/开发成本的更新的技术上,或者干 脆关停。许多铸造厂被迫在网上寻找二手零件或者 把字母和数字固定在模具上。在线购买零件很难实 现,并且使用二手零件只能是短期的解决方案。使 用固定字符是可行的,但并不划算。它们的应用和 删除十分繁琐且耗时,并且字符无法重复使用。因

product news/产品新闻 for more important production tasks and not content with such menial work, merely compounds the problem. ITT Goulds Pumps had tagging equipment that embossed one letter at a time, which made producing tags a time-consuming process. Furthermore, if the letter wheel was not stopped at the correct spot, the tag would have to be scrapped. The tagging equipment operated like a labeler where the user must spin the letter wheel to the desired character, press the lever, and then repeat this process for each letter on each tag. Illegible tagging was also a problem. The manufacturer determined that new equipment was needed to continue and improve the pattern labeling process. Numerous different solutions were tried. One solution was an automated dot peen marker with tag feeding accessories, but the marks were not legible after the tag was cast in due to the dot pattern. Work continued to improve the solution but after the process was fully implemented, the labeling results were still unsatisfactory. The search for a better, more legible solution proceeded. During this period, Kevin Lucas, pattern shop supervisor at ITT Goulds Pumps, set out to provide a temporary solution by 3D printing the legend plates. He developed a custom font of characters to create more distinguishable marks. Though legibility was improved, the time to produce the 3D molded legends was not much faster than rotating wheels. Therefore, Lucas set out to find a more effective solution to support the organization. Lucas took the initiative to identify the foundry marking requirements before looking for new equipment. He determined that an effective solution must include: • The ability to mark multiple character sizes. • Fast creation of repetitive legends. • Material that was viable for the process. • Something that fit the budget. An article in Modern Casting describing the Leading Marks tagging system caught Lucas’ interest. “We had been struggling with tagging legibility issues for years,” he said. “With our 3D printer, I had been adjusting and proving out a font and tag sizes. I printed thousands of tags, over the course of a year.” He saw that the Boss Buddy embosses foil tape for use in foundry applications such as pattern labeling, and read that the Boss Buddy is compact, simple to operate, cost-effective and uses proven components customized for foundry requirements. Leading Marks had been working with many foundries around the U.S. to improve their processes. After working with Leading Marks to test date code samples in a couple of character sizes, Lucas said he obtained much more legible marks that were created in less than half the time of the older system and with far greater ease. With favorable results in hand, they began defining what the package should include: • Interchangeable type characters in the custom font that Lucas had designed.

不满足于从事这样的琐碎工作,转而从事更重要的生产 任务,使得劳动力不断减少,问题变得更加复杂。 ITT古尔兹泵业公司的标识设备每次可以压印1个字 母,标识的制作非常耗时。此外,如果字母轮没有停 在正确的位置,则标识必须废弃。操作标识设备就像贴 标签机,用户必须将字母轮旋转到所需字符,按下操纵 杆,然后对每个标识上的每个字母重复此过程。字迹模 糊的标识也是不合格的。 企业已确定需要新设备来继续和提升铸件标识的制 作,并且尝试了许多不同的解决方案。其中一种解决方 案是使用带有标识进给附件的自动点喷笔,但由于喷 点的原因,铸造后这些标记变的不清晰。解决方案在继 续改进,但是在生产完成后,标识结果仍然不能令人满 意。因此,寻找更好、更清晰的解决方案仍在继续进 行。 在此期间,ITT 古尔兹泵业公司模具车间主管凯文·卢 卡斯着手通过3D打印来提供临时解决方案。他开发了一 款自定义的字符字体,可以创建更多可区分的标识。尽 管可读性得到了改善,但制作3D模型的时间并不比旋转 轮更快。因此,卢卡斯着手寻找更有效的解决方案。 卢卡斯在寻找新设备之前,首先明确了铸件标识的要 求。他认为有效的解决方案必须包括: • 具备标记多个字符的能力。 • 能够快速创建重复的图例。 • 有适用的材料。 • 符合预算。 Modern Casting杂志上的一篇描述Leading Marks 公司标识生产系统的文章引起了卢卡斯的兴趣。 他说:“多年来,我们一直在努力解决易读性标签的 问题。通过我们的3D打印机,我一直在调整和检查确认 字体和标识的尺寸。一年来,我打印了数千个标识。” 他了解了Boss Buddy系统压花箔带在铸造中的应 用,如模具上的标识,并且发现Boss Buddy系统紧凑 且易于操作,具有成本效益,并且有满足铸造要求而定 制的可靠组件。 Leading Marks公司已与美国各地的多家铸造厂合作 以改善其生产流程。在与Leading Marks合作测试了几 种字符大小的日期代码样本之后,卢卡斯说,他获得了 更加清晰的标识,这些标识的创建用时不到旧系统的一 半,而且更加容易。有了好的结果,他们开始确定该软 件包应包括: • 卢卡斯设计的自定义字体中的可互换字体类型。

product news/产品新闻 • Characters in a variety of sizes. • Manual Boss Buddy embossing system (vs. the automated system). The Boss Buddy system shipped to the facility in Seneca Falls, New York, in the spring of 2019. After Lucas’ preliminary use of the Boss Buddy package in the pattern shop, it moved to the shop floor. Ryan Knapp, molding supervisor at ITT Goulds Pumps uses it daily, quickly creating the pattern labels needed by the foundry. During a follow-up meeting with Laurie Barcaskey from Leading Marks, Knapp created even more clearly defined embossed characters with a simple change in the spring used in the impact press. Knapp is relieved he no longer must use the old system, aka the “Spin to Win” for pattern labels. Knapp will be championing the efforts of other departments to employ this solution throughout the plant. When asked about the implementation of the new system. Lucas said “I was pleasantly surprised that Leading Marks did not flinch when I mentioned creating dies for the font I had been 3D printing.” “Leading Marks had some great ideas on implementing the tagging project. Prior to seeing the Modern Casting piece, I was going in a different direction. It saved a lot of time going with proven equipment and a knowledgeable vendor.” ■

• 各种尺寸的字符。 • 手动Boss Buddy压花系统(相对于自动化系统而 言。 • Boss Buddy系统于2019年春季运抵纽约塞内卡 福尔斯的工厂。Boss Buddy系统在卢卡斯的模具 车间中初步使用之后交付生产车间。 ITT古尔兹泵业公司的造型主管瑞恩·克纳普每天都 使用这个系统,快速创建铸件所需的标识。经过与 Leading Marks公司的劳里·巴卡斯基在后续会议中 的探讨,克纳普更换了冲压机中所用的弹簧,得到了 更为清晰的浮雕字符。此时,克纳普将不再必须使用 旧系统,即用于模具标识的“Spin to Win”,他感 到如释重负。克纳普将为其他部门在整个工厂中采用 此解决方案提供支持。 当被问及新系统的应用情况时,卢卡斯说:“ 当我提出为3D打印的字体制作模具时,Leading Marks公司没有退缩,我感到非常惊喜和高兴。” “Leading Marks公司在完成标识项目方面有一 些很棒的想法。在Modern Casting杂志上看到这 篇文章之前,我的思路是另一个方向。现在,使用 成熟的设备、与有技术的供应商合作节省了很多时 间。” ■
