　　Silicon Carbide Anti-skinning Casting material is a high-quality Casting material that uses silicon carbide as the main raw material, adds superplasticizers and ultrafine powders, and uses pure calcium aluminate cement as a binder, which can greatly reduce the number of skinning. Because the product has good abrasion resistance and corrosion resistance, high temperature strength, high thermal conductivity, small coefficient of linear expansion, good thermal shock resistance, does not react with the cement raw material, avoiding the occurrence of crusting and crusting. The Casting material is widely used in cutting slopes, rising flues, decomposition furnace cones, and kiln tail smoke chambers of new dry cement kiln preheaters. According to the physical and chemical indicators, it is divided into two grades: KJP-50 and KJP-30.
