Medium Carbon Ferro Manganese
Manganese can change the strength, hardness, toughness, wear resistance, heat resistance and other properties of steel materials. Manganese in steel materials is mainly obtained by adding manganese ferroalloy to its melt.
Ferromanganese can be divided into high carbon, medium carbon and low carbon ferromanganese due to different carbon contents. Among them, high-carbon ferromanganese is strictly restricted due to its high carbon content. Adding it to steel materials will significantly increase the carbon content of the steel.
Ferromanganese Alloy
Low-carbon ferromanganese does not have the same problems as high-carbon ferromanganese due to its lower carbon content. Therefore, low-carbon ferromanganese is used in larger amounts than high-carbon ferromanganese and has a wider range of uses. It is used to produce stainless steel, heat-resistant cast steel, and heat-resistant cast iron. , important raw materials for wear-resistant steel and structural steel.
Ferrosilicon Manganese
In the past, the production of low-carbon ferromanganese was mainly carried out by blowing oxygen into the liquid high-carbon ferromanganese melt to decarburize the high-carbon ferromanganese into low-carbon ferromanganese. After that, silicon-manganese alloy was used to reduce the peroxidized melt. Improve manganese yield. The production process of high-carbon ferromanganese liquid oxidation decarburization method is complex, high cost and serious environmental pollution.
