Low Carbon Ferromanganese Production
Ferromanganese is segmented into two types namely, high carbon ferromanganese and medium carbon ferromanganese. The primary features of this element include good anti-oxidant properties, excellent chemical composition and low melting point. High carbon ferromanganese is an excellent antioxidant with high carbon content and is heat resistant.

The majority of producers of ferromanganese in the world use submerged arc electric furnaces. Although electric furnaces have lower capacities than blast furnaces they have the advantage that the heat requirement is provided by electricity, and coke ...
Production of Ferro- Manganese – IspatGuru
Production of Ferro- Manganese. Ferro-manganese (Fe-Mn) is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron (Fe) and manganese (Mn) with a minimum Mn content of 65 %, and maximum Mn content of 95 %. It is produced by heating a mixture of the oxides of Mn (MnO2) and iron (Fe2O3) with carbon (C ...
