Wearable corundum castable introduction
Wearable corundum castable is a refractory castable prepared by corundum aggregate and powder plus some binder. Wearable corundum castable is a kind of amorphous refractory which is widely produced and used at present. It has higher mechanical strength and abrasion resistance than high alumina refractory castable and mullite refractory castable
Wearable corundum castable features
- High strength and wear resistance
- Good resistance to spalling
- High density and low porosity
- High fire resistance, high fire resistance
- Good thermal shock stability
- Good slag resistance and corrosion resistance
