1,Product description:
The main additive of the product is imported South African andalusite, cooperate with high-grade bauxite and other raw materials and is fired at a high temperature above 1450℃. With its unique internal mineral facies structure, the product has a thermal shock resistance of more than 30 times. In addition, its high temperature performance, slag corrosion resistance and creep rate are also excellent. Therefore, the product has been widely used in hot blast stoves, ladles, coking furnaces and other high temperature industrial furnaces.
