Product introduction of wear resistant castable
Refractory material corundum castable is an amorphous refractory made of corundum as the main raw material, and then adding the required binder and admixture. It is a kind of amorphous refractory which is widely produced and used at present.
Features of wear resistant castable
Refractory material corundum castable has higher mechanical strength and abrasion resistance than high alumina refractory castable and mullite refractory castable. The fire resistance and wear resistance are more prominent than other castables, and the aluminum content of the castables of corundum series is relatively high, so the use effect is better.
Application of wear resistant castable
Corundum castables are mainly used as lining materials for boilers, blast furnace hot blast furnaces, heating furnaces, ceramic furnaces and other furnaces.
