【 Product Introduction 】 :
Brown corundum is a high-quality abrasive grade bauxite as raw material, with auxiliary materials, in the arc furnace by 2250℃ above high temperature refining, on the basis of secondary refining through high strength magnetic separation of impurities, refractoriness above 1850℃.
RS brown corundum produced by our company has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. The product has the characteristics of non-initiation, non-pulverization and non-cracking in the application process, and is often used in abrasive abrasives and fire-resistant raw materials industries.
Brown corundum is made of high quality abrasive grade bauxite as raw material, with auxiliary materials, refined by high temperature above 2250℃ in electric arc furnace, on this basis, after secondary refining through high strengthThe magnetic separator removes impurities, and the refractoriness is above 1850℃.RS brown corundum produced by our company has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. The product has the characteristics of no initiation, no pulverization and no cracking in the application process, and is often used in abrasive abrasives and refractory raw materials industries.
