It is made of aluminum silicate material and silicon carbide material as the main materials added with additive.
It can be divided into four types based on different percentage of SiC, KJP-25, KJP-35, KJP-45, KJP-55, KJP-65.
It is used for decomposition furnace slope of NSP kiln, uptake shaft, preheater cone, decomposition furnace lining, industrial furnace lining and other skinning parts. The definite using part should refer to the design of cement design institute. Normally, it is used for decomposition slope.
