Refining of Ferro-Silicon

The ferro-silicon required for making electrical steels must have low content of aluminium, calcium and carbon. But the ferro-silicon produced by carbothermic reduction process contains appreciable quantities of these impurit-ies particularly aluminium, calcium and oxygen. Hence efforts are being made to develop economically viable techniques for the refinement of eons:11min' grade ferro-silicon for use in the snaking of silicon steels. The increased interest in the refining of ferro-silicon is mainly due to its growing demand in the production of Cold Rolled Grain Oriented (CRGO) high permeability electrical steels [1].
