Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace. The oxides undergo carbothermal reduction in the furnaces, producing the ferromanganese. Ferromanganese is used as a deoxidizer for steel.
Henry Bessemer invented the use of ferromanganese as a method of introducing manganese in controlled proportions during the production of steel. The advantage of combining powdered iron oxide and manganese oxide together is the lower melting point of the combined alloy compared to pure manganese oxide.
Established in the year 1987, we, Metallic Corporation, are engaged in exporting and importing of Ferro Alloys, Metals, Minor Metals, Mineral Ores, Coke and Coal and Scrap (Ferrous & Non Ferrous). We trade in all kinds of metallic ores, minerals, scraps and ferrous alloys.
