Product Description
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.
