| Steel Fiber Reinforced Wear-resistant Castables | ||
| The castables are produced by adding some silicon carbide, mullite and steel fiber, to enhance the tensile property, strength and thermal shock resistance on the basis of the technology of optimized wear resistance castables. It is used in cutting direction entrance of cyclone separator and "target area" on cartridge of circulating fluidized bed boiler, which are the worst wear part. | ||
