Ferro Manganese

Ferro Manganese

Ferro Manganese is an alloy with high percentage of manganese, which is made by heating a mixture of the oxides MnO2 and Fe2O3 and coal & coke 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 the ferromanganese. Ferro manganese is used in producing steel for being an excellent deoxidizer and desulfurizer.

These are two variants of Ferro Manganese:
High Carbon Ferro Manganese
Medium Carbon Ferro Manganese

Features:
Excellent chemical composition
Good anti-oxidant properties
Low melting point

Applications:
Steel manufacturing
Manganese alloys

High Carbon Ferro Mangenese - 
High Carbon Ferro Manganese is the variant of ferro manganese which contains high percentage of carbon. With its high percentage carbon content, it is widely used in producing high quality of stainless steel. Â For producing this high carbon content alloy, the reduction of manganese ore is mixed with high carbon content coal and slag-forming constituents in a rotary kiln at high temperature.
