Corundum castable

Corundum castables are refractory castables prepared from corundum as aggregate and powder plus some binders. According to different parts and temperature, different corundum castables are used, such as chrome corundum castable, zirconium corundum castable, brown corundum castable, composite corundum castable. It has higher mechanical strength and abrasion resistance than high alumina refractory castable and mullite refractory castable, but its thermal shock resistance is slightly worse. It is mainly used as lining materials for various kiln such as boiler, blast furnace hot blast stove, heating furnace and ceramic kiln. The use temperature is generally above 1700 degrees.

Comparison of corundum castables and corundum mullite castables:

Corundum castables have higher strength and better wear resistance than corundum mullite castables; however, there is no thermal stability of corundum mullite castables.
