Brown Fused Alumina Sand

Brown fused alumina is called industrial teeth, in addition to the application in refractories, can also be used in sandblasting, free grinding, resin abrasive, filter media, hydraulic cutting and so on. Brown fused alumina sand put bauxite as raw material, obtained by high temperature smelting, its basic mineral is a-Al2O3, the hardness of brown fused alumina sand is high, high melting point, thermal conductivity, high temperature volume stability, not easy to crack, acid resistance,alkali resistance , suitable for casting core surface sand, paint and investment casting system shell material, and can be used as plain carbon steel, alloy steel, hard bronze, cast iron pieces of coarse grinding and free abrasive. The price of brown fused alumina is lower than that of same level white corundum, it has a better cost performance. Brown fused alumina sand often is irregular prism reddish brown or brownish black particles, bulk density: 1.65g / cm, hardness 9.1. The composition of brown corundum are (%): Al2O3: 92-98.8%, SiO2: 1.3-%. Product specifications: 16 # 20 # 24 # 30 # 36 # 46 # 60 # 80 # 100 # 120 # 150 # 180 # 200 # 240 # 260 # 280 # 320 # 400 # 500 # 600 # 800 #. Packing: 25KG / woven belt. Qingyun corundum refractory companies can also produce according to customer requirements. brown fused alumina sand Brown fused alumina sand, brown fused alumina powder is with moderate hardness, high toughness, strong anti-crushing ability, high temperature resistance, oxidation resistance, corrosion resistance, low cost, strong applicability, high purity, good crystallization, strong liquidity, low linear expansion coefficient , Corrosion resistance and other characteristics. In the application process has not detonated, not powder, no cracking, widely used in abrasive abrasive, refractories, sandblasting, grinding and polishing, wear-resistant floor of silicon carbide, precision casting mold shell production. Brown fused alumina sand can be made of sandpaper, emery cloth, grinding wheel, grinding stone, refractory materials, casting, anti-skid sand.
