Brown Fused Alumina
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.Brown Fused Alumina Grinding Is Made Of Bauxite And Coke Brown corundum is made of high-quality bauxite and refined in electric arc furnace at a high temperature of more than 2000 °C. Because of its high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance, brown corundum is the best aggregate and filler for brown corundum refractories.
For Abrasvies: F8-F220, F230-F1200. P8-P220 or according customer’s requirement.
For Refractories: 0-1mm, 1-3mm, 3-5mm, -200 mesh, 325 mesh or according customer’s requirement.
CATEGORY: Brown Fused Alumina (BFA)
