Ferro Manganese
Ferro Manganese is an alloy with high percentage of manganese, which is made by heating a mixture of oxides, MnO2 and Fe2O3 with high carbon content in blast furnace or an electric arc furnace-type system. The oxides go through carbothermal reduction in the furnaces that result in producing Ferro Manganese. Ferro Manganese is used as deoxidizer and desulfurizer for production of steel.
There are three variants of Ferro Manganese:
- High Carbon Ferro Manganese
- Medium Carbon Ferro Manganese
- Low Carbon Ferro Manganese
