Corundum mullite castable
Introduction:
Corundum mullite castable is also called corundum mullite wear-resistant castables. Because of the wear-resistant properties of corundum and mullite refractory raw materials, refractory castable named after raw material and properties. The corundum mullite castables are made of brown corundum, white corundum, andalusite, mullite and high-quality bauxite. The ultra-fine powder refractory powder is prepared by scientific formula mixing. The mullite contained in the corundum refractory castable is relatively rare in nature, and the industrial mullite raw materials are artificially synthesized, with high purity and high density.
Advantages:
Good structure, low creep rate, low thermal expansion, good thermal shock resistance and strong chemical resistance.
Application:
It is widely used in various of industrial furnace / kiln, such as cement rotary kiln, lime kiln
