What is Refractory Anchoring Systems? What are its types, benefits and characteristics?

It is supposed that up to 40% of refractory lining failures are due to Refractory Anchoring Systems in Spain design or improper installation problems. This is quite a few. When designing refractory linings for industrial applications, anchor design is an essential factor in creating an improved lining with proper support. In particular, the anchor tip is close to the hot surface, so it has the highest temperature and is an important consideration.

Anchors have several functions. To a lesser extent, anchors also help support the load of refractory weights.

Here are three important metal fixing tips you need to know to create a monolithic Refractory Anchors in Spain that has the right support and maximizes its service life.

Anchor type and operating temperature In Refractory fasteners in Italy to use a metal anchor system, engineers and designers of the refractory material often use a different grade, austenitic stainless steel anchor. Complex grades of stainless steel used are AISI 304, 309, 310. They contain chromium and nickel, which provide the best corrosion resistance and ductility at high temperatures. Even the AISI 330 and Inconel 601 may be used in some applications where the temperature is more extreme. The use of ceramic tile anchors is impractical for various reasons. These anchors have a high nickel content and are more resistant to oxidation and tensile strength at a temperature: 2000 ° F or higher.

Requirements and refractory characteristics Certain requirements must be imposed on the refractory, depending on the conditions under which the refractory is exposed in the furnace area where the refractory is used.

High temperature is resistant.

The Refractory Anchors for Cement Kilns in Italy must win under normal conditions in the area where they are used and withstand temperatures that can be won under adverse conditions. Not only must it be capable of withstanding high temperatures without melting, but it must also maintain structural strength at temperatures at its melting point and maintain a constant volume even when exposed to high temperatures for increased periods.

Chipping resistance Significant changes in the shutdown, start-up, or operation of the furnace generally cause large temperature changes in the furnace. The refractory must have the impact resistance required to withstand such temperature changes. Without this quality, the bricks can crack. These cracks, commonly referred to as chipping, occur horizontally in the brick. Peeling is the result of thermal shock. The same reaction can be seen when drinking a glass. If you put a cold glass in very hot water, the thermal shock will crack the glass. However, if you slowly raise the temperature of the water in the glass, there will be no thermal shock, and the glass will not be damaged. The same applies to refractories in ovens. When cooking in a cold oven, the temperature of the refractory should be raised very slowly to avoid crushing.

Resistance to chemical attacks (resistance to slag).

During the cleansing process, ash, slag, and vapour formed during the combustion process can attack refractories and chemically react with bricks, depending on the type of fuel used. In addition, dust and alkali mixed in the kiln gas can adhere to the bricks in the combustion zone and react with refractories. The ability of Refractory Anchor Manufacturer to resist these chemical attacks is called slag resistance. Bricks that do not have this strength can be significantly weakened by chemical attacks, leading to premature refractory damage.

Abrasion resistance.

Due to the conditions found in rotary kilns, refractories must resist the polishing action caused by the dust entrained by the sliding kiln supply floor and the moving gas stream. This wear resistance is a prerequisite for all bricks installed before and after the combustion zone, where the lining is not normally formed.

Cover.

One of the important qualities required for refractories in combustion zones where the highest temperatures are present is obtaining a good coating and maintaining this coating for extended periods. The importance of lining in the combustion zone is discussed. Just as refractory acts as a protection for the furnace shell, so does the tom lining. For refractories, therefore, helps extend the life of the bricks in the burning zone.
