Abstract
It is well known that lowering the carbon content offerro-alloy increases the value of the metal. This grade of ferro-alloy results in lowering the cost of production in steel melting stage. Alurninothermic process produces carbon free ferro-alloys. In this paper, details of investigations onferro-manganese making are given.- Influence ofpre-reduction of manganese ore to Mn7O3 and Mn .,stage, excess aluminium overstoichiometric requirement, addition of fluxes etc., on metal yield is discussed. Metal yield of 58-64% on 10 kg scale with alloy composition of Mn-83%, Fe-13%, Si-1.4 to 2%, Al-0.008% and P-0.16% has been successfully achieved at the Laboratory.
