White fused alumina  refractory material Indroduction

1.Production process.

White fused alumina is produced by fusing alumina block in an electric arc furnace under carefully controlled conditions.The material produced is white in color,dense and has predominatly large crystals of Alupha Alumina.Ingots are are crushed,ground,and precision screened in new sizing plant to obtain very consistent sized fractions.Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products.Close sized fractions are available or precision blended to specification.This process ensures a very consistent sizing from coarse to fines which is critical in many applications.
