According to the different content of Cr2O3, chrome oxide brick is divided into high-purity chrome oxide brick, medium-grade chrome oxide brick and chrome corundum brick. The main raw materials are electric melting chromium oxide, electric melting corundum and additives, which are fired at high temperature in the edge kiln. The product has high density, low porosity, high strength, good wear resistance, strong heat shock resistance and acid and alkali corrosion resistance.
High purity chrome oxide brick and medium grade chrome oxide brick are mainly used in alkali free glass fiber furnace and chemical industry furnace,medium grade chrome oxide brick and chrome corundum brick are mainly used in the slideway of waste incinerator, carbon black furnace, copper smelting furnace, glass furnace, zinc smelting furnace and steel rolling heating furnace.
