Product Details
Fused Cast AZS blocks are the most widely used materials both in glass contact and superstructure of glass melting furnaces. The products are made of high pure material, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity, good erosion resistance and widely be used for linings of furnace in industries.
Casting method of AZS series products: fused cast bricks are made by completely melting the raw materials and casting them in the mold, after cooling and solidification. Therefore, the shrinkage holes caused by the volume shrinkage during the condensation process are a matter of special attention when using. Generally, bricks with shrinkage holes are used in parts that do not have strict requirements for use. In some parts, according to the requirements of its use, shrinkage holes can be used to offset or cut the bricks of the shrinkage holes. Different casting methods can meet various usage requirements.
