The high-strength wear-resistant self-flowing castables are made of high-quality bauxite clinker, mullite and fused corundum. The pure calcium aluminate cement, corundum micro-powder and silicon micro-powder are used as binders. It has the characteristics of high strength, good thermal shock resistance, abrasion resistance, erosion resistance and strong corrosion resistance. It has good fluidity and convenient construction. It can be used in CFB boilers and other high temperature furnaces.
