High Carbon Ferro Manganese
High-carbon ferromanganese , also known as standard ferromanganese, is one of the manganese ferroalloys smelted directly from manganese ores. The manganese content ranges from 74 to 82% and the carbon content ranges from 7 to 7.5%. It is produced either in a blast furnace or in an underwater arc furnace.
Product Introduction
High-carbon ferromanganese, also known as standard ferromanganese, is one of the manganese ferroalloys smelted directly from manganese ores. The manganese content ranges from 74 to 82% and the carbon content ranges from 7 to 7.5%. It is produced either in a blast furnace or in a submerged arc furnace. The alloy is melted either with high-manganese slag or with overburden slag. High manganese slag uses slag with an Mn content of 30–42%. Because of its high manganese value, the slag is reused as feedstock for the production of manganese metal by the electrolysis process or for the production of silico-manganese alloys. The addition of lime is avoided to keep the manganese content high. In practice, slag with an Mn content of 10–20% is disposed of. This content is too low to economically recover further manganese values. Lime is used to keep the manganese content in the slag low.
High carbon ferromanganese is an important manganese ore in the metallurgical industry. High-grade steel is deoxidized and desulfurized during melting. Adding a suitable amount of ferromanganese to molten steel can reduce the harmful elements and improve the quality of steel. In the steel industry, the consumption of ferromanganese is about 3-5 kg of FeMn75# to produce one ton of steel.
In the foundry industry, high carbon ferromanganese serves as a nucleating and nodulating agent for ductile iron castings. It accelerates graphite precipitation, shortens nodulation time, reduces impurities in the melt, and improves ductility and hardness of the cast iron. In addition, ferromanganese is used in the foundry industry to increase the carbon content of the melt, which improves the hardness and wear resistance of the cast iron.
High carbon ferromanganese is also used as a deoxidizer and desulfurizer in petroleum refining. The high-manganese slag produced during refining is reused as feedstock for the production of high-manganese steel, which is used in the manufacture of turbine blades and other high-performance components.
In the production of refractory materials, abrasives and other products that require high hardness and wear resistance, high carbon ferromanganese is an ideal material, and the high manganese slag from the refining process is also used as a feedstock for the production of refractory materials.
In summary, high carbon ferromanganese is widely used in the metallurgical industry. Due to its high manganese content, it is suitable for the production of high-grade steel, ductile iron and other high-performance materials

Application
Ferromanganese is used in the steel industry: Ferromanganese is used as a deoxidizer and desulfurizer in steel production. High quality steel is deoxidized and desulfurized during melting. By adding a suitable amount of ferromanganese to the molten steel, the harmful element can be reduced and the quality of the steel can be improved. In the steel industry, the consumption of ferromanganese is about 3-5 kg FeMn75# to produce one tonne of steel.
Ferromanganese is used in the foundry industry: Ferromanganese is used as a nucleating and nodulating agent for ductile iron castings. It accelerates the graphite precipitation, shortens the nodulation time, reduces the impurities in the molten steel, improves the quality of the cast iron, reduces the clogging of the melting furnace nozzle and effectively prolongs the life of the melting furnace.
Ferromanganese is used in other industries: High carbon ferromanganese is used as a reducing agent in the production of low carbon ferroalloys. HC ferromanganese powder can also be used in welding materials and mineral deposition. High manganese ferromanganese can be used in the electrical industry to produce pure semiconductor manganese and in the chemical industry to produce manganese ketone.
