High Purity Alumina Chromic Oxide Brick 1800°C With Wear Resistance
The chrome corundum brick products I produce are made of corundum and fused chromium oxide as the main raw materials, with micro powder and other additives, after mixing, forming, drying, and firing at high temperature in shuttle kiln. Products with wear resistance, heat shock, acid and alkali erosion and other characteristics. High chromium brick (Cr2O3≥90%) is mainly used in coal chemical industry, chemical industry kiln, alkali free glass fiber kiln, garbage incinerator and other key parts of kiln;
Chrome corundum brick is mainly used in the lining of carbon black furnace, copper smelting furnace, glass furnace melting pool, steel rolling furnace slide, steel platform. Product size, physical and chemical indicators, service life has reached or exceeded the level of similar products at home and abroad.
