Brown fused alumina is produced through the high-temperature smelting of bauxite in an electric arc furnace. Following the processes of raw material sorting, electrolytic smelting, crushing, ferromagnetic separation, screening, physical and chemical inspection, finished product packaging, and warehousing, brown fused alumina grinding is created. Brown corundum, derived from high-quality bauxite, undergoes refinement in an electric arc furnace at temperatures exceeding 2000 °C. Renowned for its exceptional purity, exquisite crystallization, remarkable fluidity, minimal linear expansion coefficient, and commendable resistance to corrosion, brown corundum proudly stands as the premier aggregate and filler for brown corundum refractories.
