Brown Fused Alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000°C. A slow solidification process follows the fusion, to yield blocky crystals. brown fused alumina manufacturer The melting help in removing residual sulphur and carbon , Strict control over Titania levels during the fusion process ensures optimum toughness of the grains.
Then The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use. Dedicated lines produce products for different applications.
Raw material sorting → electrolytic smelting → crushing → ferromagnetic separation → screening → physical and chemical inspection → finished product packaging → inventory
Brown corundum has the advantages of high temperature resistance, corrosion resistance, high hardness, high strength, wear resistance, good crystallinity, and low expansion coefficient.
Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Brown Fused Alumina thermal properties make it an excellent material for use in the manufacture of refractory products. corundum wholesale Brown Fused Alumina is also used in other applications like blasting and surface hardening.
