Corundum castable refractory is divided into cement-free corundum castable refractory and cement corundum castable refractory. Also there are different kinds of corundum castables refractory made by CH refractories company according to different raw material. For example, white fused alumina manufactured corundum castable refractory, brown fused alumina manufactured corundum castable refractory.
Corundum castable refractory is the refractory castable prepared from corundum as aggregate and powder plus some binder. It has higher mechanical strength and abrasion resistance than high aluminum refractory castables and mullite refractory castables, It is mainly used as lining material for boilers, hot blast furnaces, heating furnaces, ceramic kilns, etc.
Corundum castable refractory has good properties of high strength, good high temperature performance, stable volume, low thermal conductivity, strong resistance to slag penetration, erosion resistance, convenient construction, strong furnace structure.
Applications of Corundum Castable:
Steel furnace, cement kiln, glass kiln, iron making furnace, ceramic tunnel kiln and so on.
