Application

Corundum refractory castables have higher mechanical strength and abrasion resistance than high-alumina refractory castables and mullite refractory castables, but their thermal shock resistance is slightly worse. It is mainly used as the lining material of boilers, blast furnace hot blast stoves, heating furnaces, ceramic kilns and other kilns.
