SUOYI Brown Alundum Ship Hull Cleaning Abrasives Grit

Brown corundum, also known as emery, is a brown artificial corundum produced by melting and reducing three raw materials: alumina, carbon materials, and iron filings in an electric arc furnace, hence its name. The main chemical component of brown corundum is AL2O3, its content is 95.00%-97.00%, and it also contains a small amount of Fe, Si, Ti, etc. Brown corundum is the most basic abrasive and is widely used because of its good grinding performance, wide range of applications and low price.

Brown Fused Alumina is fusing under the high temperature of above 2250°C with high quality abrasive bauxite as raw material. It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can produce ceramic grinding wheel ,resinoid grinding wheel. And BFA could be used for abrasive,sandblasting and precision casting.

Brown Fused Alumina

Brown fused alumina 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 corundum 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.
