Brown Fused Alumina
Brown Fused Alumina
Product Code : 20
Product Description

Having quality oriented approach, we are able to offer the best grade Brown Fused Alumina. This product is produced by smelting quality-assured calcined bauxite with the aid of our modern electric arc furnaces. Finds wide applications in blasting and surface hardening, provided product is widely demanded for grinding metals of high tensile strength. Available in various packaging options, provided Brown Fused Alumina can be bought from us at economical prices.

Key Points:

  • High strength
  • Suitable for manufacturing refractory products
  • Sharp abrasive in nature
  • Safe to use

Process of Production

Brown Fused Alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000oC. A slow solidification process follows the fusion, to yield blocky crystals. 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.

Application :

Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening.
