Brown fused alumina introduction
Brown fused alumina, local name, also known as carborundum, is made of alumina, carbon materials, scrap iron three kinds of raw materials in electric furnace melting reduction and made of brown alundum, reason for this name.Brown fused alumina is mainly chemical composition is AL2O3, and its content from 94.5% to 94.5%, the other contains a small amount of Fe, Si, Ti, etc.
Brown fused alumina is bauxite, coke, anthracite as main raw materials, in the Canon of high temperature smelting electric arc furnace and become, use it made of abrasive, suitable for grinding the high tensile metals, such as all kinds of steel, malleable cast iron, hard bronze, etc., also can make advanced refractories.Brown fused alumina with high purity, good crystallization, strong liquidity, low linear expansion coefficient, the characteristics of corrosion resistance.The dozens of refractory production enterprises have proved that the product in the application process has not initiation, not pulverization, not cracking characteristics.Especially its far higher than the traditional brown corundum price, more make it become the best in the brown just the quality of the jade of refractory aggregate and filling material.
