Product Description Surface Preparation Brown Fused Alumina Grit Blasting MediaProduct DescriptionBrown fused aluumina is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard. High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.The brown aluminum oxide abrasive has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion, and corrosion resistance. The practice of dozens of fire-proof production companies has verified that this product has the characteristics of no explosion, no chalking, and no cracking in the application process. In particular, it is much higher than the cost-effectiveness of traditional brown corundum, making it the best aggregate and filler for fused alumina refractories By Al2O3:95% Al2O3 Grade A Brown aluminum oxide92% Al2O3 Offset A Brown aluminum oxide85% Al2O3 Grade B Brown aluminum oxideBy application: By smelting type: By crushing type:F sand for Bonded Abrasives Tilting furnace BarmacP sand for coated Abrasives Fixed Furnace RollingBy Additional treatment:Middle temperature calcined Brown aluminum oxide,High temperature calcined Brown aluminum oxide,Coated Brown aluminum oxideHigh temperature calcined & coated Brown aluminum oxide (AHMCF)Product ParametersPurposeSpecificationChemical composition(%)Magnetic material ≤Al2O3(≥)Fe2O3(≤) SiO2≤TiO2≤abrasive F grit4#-80#95.00.31.53.00.0590#-150#94.00.03180#-240#93.03.50.02P grit8#-80#95.00.21.23.00.05100#-150#94.00.03180#-220#93.00.31.53.50.02Micro PowderW0.5-W63F320-F150092.50.51.84.0 refractorySize for Sand0-1mm 1-3mm3-5mm 5-8mm 8-12mm95.50.31.5(1.0 Tilting Furnace)3.0 0-3mm 0-5mm0-10mm 0-25mm95.00.31.53.0 Fine powder100F 200F 325F94.50.51.53.5 GRADE BChemical Analysis(%)Physical PropertiesAl2O370-85%Specific Gravity3.50-3.90g/cm3Fe2O3 8-15%Bulk density1.30-1.90g/cm3SiO22-5%Mohs Hardness7.0-9.0TiO2 3-5% C GRADEChemical Analysis(%)Physical PropertiesAl2O350-65%Specific Gravity3.50-3.90g/cm3Fe2O312-20%Bulk density1.30-1.90g/cm3SiO2 15-25%Mohs Hardness7.0-9.0TiO2 4-6%// ItemIndexColourDark brown(Deep blue after calcination)Crystal formTrigonal crystalHardness(MO)≥9.0Melting point(°c)2250Maximum service temperature°c1900True density(g/cm3)≥3.9Coefficient of linear expansion7-9 Applications for refractory :Unshaped refractory, stereotypes refractory, castable, ladle refractory, blast furnace hot air furnace series combination brick, high alumina brick, carbon refractory, mullite brick, gun mud, Bulk materials, ceramic bricks, composite bricks, corundum products, charge, pound, refractory raw materials, abrasive raw materials, used in steel mills, foundries, glass factory high-end refractories.
