Brown fused alumina small grinding wheel 6*1*10

Brown corundum, the full name of fused brown corundum, the common name is also known as emery. It is an artificial brown corundum obtained from bauxite, carbon and iron filings through high-temperature smelting reduction in an electric arc furnace. The main chemical composition of brown corundum is alumina, and it also contains a small amount of iron, silicon, titanium and other substances. Brown corundum is called industrial teeth, and its outstanding advantage is high toughness. According to the smelting method, it can be divided into fixed furnace brown corundum and pouring furnace brown corundum. According to the alumina content, it can be divided into first-class brown corundum, second-class brown corundum, and third-class brown corundum. Since the main raw material is natural mineral bauxite, the taste and impurities vary greatly, so it is particularly necessary to pay attention to the quality control ability of the factory.
