Product Description

  Product Overview:

     Refractory cushion mortar is a special Refractory mortar that cushions the thermal expansion stress of refractory masonry made of compressible refractory raw materials. Mainly used in blast furnace, coke oven, hot blast furnace and other industrial kiln refractory masonry to buffer thermal expansion stress. According to its physical and chemical indicators, it is divided into four brands: HCN-L, HCN-G1, HCN-G2, and FHCN-TG.
