Definition of anchor: The component that connects the integral refractory lining or refractory prefabricated block to the furnace shell or furnace body steel structure is called anchor.
The function of anchors is to fix the integral lining or precast components in a certain position to resist static loads, thermal stresses, mechanical rotation or vibration. Anchors also help to prevent the collapse of materials during construction and before the ceramic bond is formed during heating, and help to evenly distribute shrinkage and avoid large and concentrated cracks in the masonry.
What are the materials and shapes of anchors?
The anchors are made of metal and ceramic.
Metal anchors are made of low carbon steel, heat-resistant alloy steel and nickel-chromium alloy. The materials are divided into low carbon steel, silicon steel, ferrochrome, 320 stainless steel, 309 stainless steel, 310 stainless steel, chromium-nickel-iron alloy, and the maximum operating temperature can reach 1200℃.
Ceramic anchors are made of refractory raw materials through molding and firing. Their materials are divided into clay, high alumina and corundum, and the maximum operating temperature can reach 1800℃.
There are many shapes of anchors: Y-shaped, V-shaped, T-shaped, S-shaped, tortoise shell net, etc.
