Classification And Instructions For Use Of Corundum Castables
Corundum castable mainly refers to the high-temperature main crystal phase as the refractory a-AL2O3, its refractory temperature, wear resistance and structural strength are high, is widely used in high-temperature industrial kiln contact solution or wear layer castable. The main bone powder and powder of corundum castable are special high bauxite clinker, and pure aluminate cement binder, which is a kind of amorphous refractory material.
Subwhite corundum: subwhite corundum castable is made of calcined alumina or industrial alumina as raw material, melted at high temperature in electric arc furnace, white, large crystals, many holes, the porosity is basically 6%-10%, the main crystalline phase is alumina micro-powder, the shape of the crystal is thin or diamond, the content of alumina is basically more than 98.5%
