The usage temperature of corundum castables is generally above 1700 degrees, and they are mainly used as lining materials for various kilns such as boilers, blast furnaces, heating furnaces, ceramic kilns, etc.
Comparison between Corundum Castables and Other Castables
Corundum castables have higher mechanical strength and wear resistance than high alumina refractory castables and mullite refractory castables, but their thermal shock resistance is slightly inferior.
Corundum castable is a refractory castable prepared by adding some binders to corundum as aggregate and powder. Different types of corundum castables are selected based on their usage location and temperature, including chromium corundum castables, zirconium corundum castables, brown corundum castables, composite corundum castables, etc.
