Company profile:ZIBO HITECH MATERIAL CO., LTD is the specialized manufacturer and supplier of refractory in China, Our products mainly include refractory bricks, refractory castable, refractory precast shape, insulating brick etc. For refractory castable and precast shape they are very popular in the Europe, North American area.
Type:We can supply High alumina low cement castable,Mullite low cement castable,Corundum low cement castable,High alumina self flowing castable,Mullite self flowing castable,Corundum self flowing castable,AZS Castable,Zircon-Mullite Castable,Zircon-mullite Ramming Mix etc.
Advantage:Our Corundum self flowing castable: No vibration can been pouring construction of the refractory castable. Its characteristic is that no vibration can be gravity pouring into various shapes with not reduce or not significantly reduce the pouring material performance conditions,especially adapted to the thin wall or complex shape, unable to vibration construction of industrial kiln site.
Application: they are widely used in various kinds of kiln lining.Such as boiler, blast furnace hot blast stove, heating furnace, ceramic kiln, etc
