Refractory -320/325mesh Brown Fused Alumina Powder
China [CN] Refractory -320/325mesh Brown Fused Alumina Powder
Brown Fused Alumina is fused in the electric-arc furnace under the high temperature of above 2250°C with high quality bauxite as raw material and matched by the carbon material and scrap iron .Then, it was crushed by autogenous mill, removed the iron through magnetic separation, screened to variety granularity.
