Manganese is one of the most important alloying elements in steel materials. Manganese can alter the strength, hardness, toughness, wear resistance, and heat resistance of steel materials. Manganese in steel materials is mainly obtained by adding manganese iron alloy to its melt.


Manganese iron can be divided into high carbon, medium carbon, and low carbon manganese iron due to its different carbon content. Among them, high carbon ferromanganese is strictly limited due to its high carbon content, which can significantly increase the carbon content of steel when added to steel materials. Low carbon ferromanganese does not have the same problems as high carbon ferromanganese due to its low carbon content. Therefore, low carbon ferromanganese has a larger amount and wider use than high carbon ferromanganese, and is an important raw material for producing stainless steel, heat-resistant cast steel, heat-resistant cast iron, wear-resistant steel, and structural steel. In the past, the production of low-carbon ferromanganese was mainly achieved by blowing oxygen and decarbonization into the liquid high carbon ferromanganese melt to convert it into low-carbon ferromanganese. Afterwards, silicon manganese alloy was used to reduce the oxidized melt to improve the yield of manganese. The production process of liquid oxidation decarbonization of high carbon ferromanganese is complex, costly, and seriously pollutes the environment.
