Chrome Tile

The chrome corundum products produced by our company are made of corundum and electrofused chromium oxide as the main raw materials, with micronized powder and other additives, after mixing, molding, drying, and firing at high temperature in shuttle kiln. The products have the characteristics of wear-resistant, heat shock-resistant, acid and alkali erosion-resistant. High chrome bricks (Cr2O3≥90%) are mainly used in coal chemical industry, chemical industry kiln, non-alkali glass fiber kiln, waste incinerator and other key parts of the kiln; chrome corundum bricks are mainly used in carbon black furnace, copper smelting furnace lining, glass kiln melting pool, rolling steel heating furnace chute, steel platform. The external dimensions, physical and chemical indexes and service life of the products have reached or exceeded the level of similar products at home and abroad.
