  Usually the refractory castable with Al2O3 content (mass fraction) greater than 90% is called corundum refractory castable, and its main phase is corundum, because corundum has the characteristics of high melting point (2050℃) and strong resistance to slag erosion, which makes corundum high-quality castables have high refractoriness and good chemical stability. The refractory raw material combination of corundum refractories has many forms, such as: (1) Corundum refractory castable use white corundum as aggregate and powder. (2) Use plate-shaped alumina and dense (sintered) alumina as aggregates, and use dense (sintered) alumina as powder; (3) Sub-white corundum or brown corundum is used as aggregate, and dense (sintered) alumina is used as powder; (4) Use white corundum and super bauxite clinker as aggregate, white corundum as powder, etc. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric fu...
