Product description:
The product uses fused white corundum sand as the main raw material (Al2O3 > 98%) and is fired at 1600℃~1700℃ high temperature after shaping by high-tonnage moulding machine. For this reason, the product has excellent performance, acid resistance, alkali corrosion resistance, good wear resistance and high temperature resistance. It is widely used in iron and steel industry furnace, chemical furnace, incinerator and other high-temperature industrial furnace and so on.
