Product Description





Brown fused alumina


Chemical composition: AL2O3
Material: Bauxite, carbon material, iron filings
Color:sepia


Brown fused alumina Properties and Application:

Brown fused alumina, common name also known as emery, is made of bauxite, carbon materials, iron filings three kinds of raw materials in the arc furnace after melting and reduction of the brown man-made corundum, so this name. The main chemical composition of brown corundum is AL2O3, its content in 95.00%-97.00%, and contains a small amount of Fe, Si, Ti, etc. Brown corundum is the most basic abrasive, because of its good grinding performance, a wide range of application, cheap, has been widely used.
Brown fused alumina is bauxite, coke (anthracite) as the main raw material, in the arc furnace by high temperature smelting, with it made of abrasive, suitable for grinding high tensile metal, such as all kinds of general steel, malleable cast iron, hard bronze, etc., can also manufacture senior refractory materials. Brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance. Through the practice of dozens of refractory production enterprises, the product has the characteristics of no detonation, no powder, no cracking in the application process. In particular, it is much higher than the traditional brown corundum cost performance, but also become the best brown jade refractory aggregate and filling material.
