High Quality Min 95% Al2O3 Brown Fused Alumina

Product Description:

Brown fused alumina is made of bauxite and coke (anthracite) as the main raw material. It is smelted in high temperature furnace by high temperature. The main chemical composition is AL2O3, TiO2 ring contains a small amount of SiO2 and Fe2O3, and the microhardness is HV1800-2200. SiC is high, and the grinding tool made of it is suitable for grinding high tensile resistance metals, such as various general steels, malleable iron, hard bronze, etc., and can also manufacture advanced refractory materials. The brown corundum is made of high-quality abrasive grade bauxite, which is made by melting at 2000 °C in the arc. It is crushed and shaped by self-grinding machine, magnetically removed and sieved into various particle sizes. Its texture is dense, hardness is high, and grain formation Spherical, suitable for the manufacture of ceramics, resin high-solidified abrasives, as well as grinding, polishing, sand blasting, precision casting, etc., can also be used to manufacture advanced refractory materials, code "A" in accordance with international common standards, national standards, most for export, There is also a certain amount of supply to domestic users.
 

Brown Fused Alumina Application & Advantage:

1) Due to the high temperature resistance, corrosion resistance, high strength and other properties, the brown fused alumina is commonly used for pouring steel sliding nozzles, smelting the lining (wall and tube) of rare precious metals, special alloys, ceramics, ironmaking blast furnaces; physicochemical vessels, spark plugs, Heat resistant oxidation resistant coating.
(2) Due to its high hardness, good wear resistance and high strength, in the chemical system, brown fused alumina is used as various reaction vessels and pipes, parts of chemical pumps; mechanical parts, various molds, such as wire drawing Mold, squeeze pencil core mold mouth, etc.; make tools, mold abrasives, bulletproof materials, human joints, sealing mold rings, etc.
(3) Corundum insulation materials, such as corundum lightweight bricks, corundum hollow spheres and fiber products, brown fused alumina is widely used in furnace walls and furnace roofs of various high-temperature furnaces, both high temperature and heat preservation. The brown corundum granular sand is made of artificially selected brown corundum pieces, which are processed by rolls, ball mills, barmac and other equipment. The particle size is from F8-F325. It is mainly used for polishing, grinding and industrial grinding.
