BROWN ALUMINIUM OXIDE Industrial Grade

     Commonly known as brown corundum also called emery, is made of alumina, carbon materials, iron three kinds of material in the furnace through the ablation restoration making Tan artificial corundum, so this name. The main chemical composition of brown corundum is AL2O3, its content in 94.5%-97%, the other is rich in a small amount of Fe, Si, Ti and so on.

                                   40# brown fused alumina metric tons for export

     Brown corundum 40 mesh, 46 mesh, brown corundum, brown corundum and commonly known as carborundum, is made of alumina, (coke or anthracite), iron three kinds of materials in 2000 degrees above the furnace through the ablation restoration making Tan artificial corundum, so this name. Brown corundum by self shaping mill, magnetic separation, sieve sharing a variety of size, its dense texture, high hardness, the formation of spherical particles, suitable for making ceramic and resin high consolidation abrasive and grinding, polishing, sandblasting, precision casting and so on, also can be used for the production of high-grade refractory materials.

   Main features of brown fused alumina:

(1) because of the high temperature resistance, corrosion resistance, high strength and other properties, the use of cast steel slide gate, the exercise of rare metals, special alloy, ceramics, blast furnace lining (wallsandtubes); physicalandchemicalcontainers, spark plugresistancethermaloxidation resistant coating. (2) Zong Gangyu main chemical composition is AL2O3, its content in 94.5%-97%, the other contains a small amount of Fe, Si, Ti, etc.. After crushing plastic, magnetic separation, sieve into a variety of sizes, with its dense texture, high hardness, the formation of spherical particles, suitable for making ceramic and resin high consolidation abrasive and grinding, polishing, sandblasting, precision casting and so on, also can be used in the manufacture of high-grade refractory materials. Corundum level corundum principal component is alumina, aluminum content grades also used to distinguish, aluminum content lower hardness is low (3) corundum thermal insulation material, such as corundum brick, alumina hollow ball and fiber products, widely used in all kinds of high temperature furnace furnace wall and roof, which can endure temperature and thermal insulation. Brown corundum is featured by artificial corundum block, the roller, ball milling, Barmac processing equipment, particle size by F8-F325. is mainly used for polishing, grinding, grinding and other industry, also can be processed according to customer needs for water washing, acid treatment and other methods, to customer satisfaction is not the same as needed. Mainly used for ceramic abrasive, abrasive, abrasive, high-grade organic abrasive, coated abrasives, the carbon content is divided into: Calcined corundum C = 0.05%, C = 0.10%, low carbon corundum, brown corundum C is less than or equal to 0.15%.

     Brown fused alumina abrasive material has the characteristics of high purity, good crystallinity, strong mobility, low linear expansion coefficient and corrosion resistance. In the process of use, with no initiation, no powder, no cracking characteristics.

     It is fused with excellent abrasive grade bauxite as raw material, with accessories in electric arc furnace with high temperature above 2250 DEG from the essence. Its self sharpening is good, the grinding force is strong.
