Corundum castable is using fused white corundum or alumina as refractory aggregate, adding a variety of superfine powder and calcium aluminate cement as binder, to produced to unshaped refractory material by proportion mixing.The alumina content of corundum castable is more than 85%.
Characteristics of Corundum Castable：
Good thermal shock stability, spalling resistance, wear resistance and acid medium corrosion resistance.
Application of Corundum Castable：
It is mainly used in combustion chamber, separator and flue of circulating fluidized bed boiler.
