Tabular corundum castable uses high-purity, high-melting plate-shaped corundum as the main raw material, combined with high-quality active alumina fine powder and other raw materials. At the same time, by adding silicon carbide, the corrosion resistance of corundum castable is greatly enhanced.
Tabular corundum castable is mainly used for outlet and burners of high temperature furnaces/kilns.
