Ferromanganese is a kind of ferroalloy that is composed of iron and 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.

It can be divided into High carbon ferromanganese/HCFeMn(C:7.0%-8.0%),Medium carbon ferromanganese/MCFeMn:(C:1.0-2.0%),and Low carbon ferromanganese/LCFeMn(C<0.7%). it is available in a wide range of sizes .

Ferromanganese production takes manganese ore as raw material and lime as auxiliary material,uses electric furnace to smelt.

Application:

①Ferromanganese performs well in steel-making,it is deoxidizer and alloying constituent,and meanwhile can reduce sulfur content and damage caused by sulfur.

②Liquid ateel mixed by ferromanganese can improve mechanical properties od steel with high strength,toughness,wear resistance,ductility,ect.

③Ferromanganese is a very important auxiliary material in steel-making and iron casting industries.
