Ferromanganese,a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon in a furnace. They undergo a thermal decomposition reaction. It 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. In China the standards of ferromanganese produced by electric arc furnaces can be divided into following grades.Be used to :medium carbon/low carbon ferro manganese is mainly used in producing special steel. as the deoxidizer and alloy additives, which could strengthen the steel rigidity,ductility,toughness and abrasion resistance, Ferro manganese is one of the major raw material for steel making and suitable for electric welding rod.
