China High Purity Brown Fused Alumina Industrial Grade Aluminium Oxide, Find details about China Brown Fused Alumina Abrasive, Brown Fused Alumina Price from High Purity Brown Fused Alumina Industrial Grade Aluminium Oxide
Brown fused alumina is made from bauxite coke by high temperature smelting in electric arc furnace. After raw material sorting, electrolytic smelting, crushing, ferromagnetic separation, screening, physical and chemical inspection, finished product packaging, warehousing and other production processes. It has the characteristics of high hardness, good crystallization, good linear fluidity, less adhesion in use, non-explosion, non-cracking and non-pulverization in use. The abrasives made by him show dark blue after calcination, no network cracks and no rust spots
