We have passed the ISO 9001 and CTC certification,and every customer in this world is welcome to have a visit to our company and factory to check our strength.
Corundum Refractory castable with corundum as aggregate and powder and some binder. It has higher mechanical strength and abrasion resistance than high alumina refractory castable and mullite refractory castable, but its thermal shock resistance is a little worse. Mainly used as boiler, blast furnace, hot blast furnace, heating furnace, ceramic kiln and other furnace lining material.
