Alkali Erosion Alumina Chrome Brick Refractory Used In Garbage Incinerator
At present, the application of aluminum chrome brick has been more widely used, one is made of metal chromium slag as the main raw material of chromium corundum brick, the product is widely used in zinc smelting furnace, volatile kiln, chromium corundum brick has excellent thermal vibration stability and high temperature creep performance, and meet the requirements of national circular economy.
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;
