Advantages of ferro manganese
Improve the performance of steel
Manganese in ferro manganese is a common alloying element, which can significantly improve the physical and chemical properties of steel, such as increasing hardness, strength, toughness, etc. It can also enhance the corrosion resistance and anti-wear properties of steel and improve its service life.
Reduce production cost
Ferro manganese can replace pure manganese and electrolytic manganese to reduce the cost of raw materials, and at the same time, it can also improve furnace temperature, accelerate the reaction speed, and reduce the amount of lower foot in the process of steel production to reduce production cost.
Optimize the steel production process
Manganese impurities can play a passivating role to reduce the generation of oxides in the steel, while ferro manganese as a deoxidizer can remove oxides and air bubbles in the steel, thus optimizing the steel production process and improving the quality and yield of steel.
Beneficial to environmental protection
Ferro manganese can effectively reduce the emission of pollutants in the process of steel production, such as reducing the emission of nitrogen oxides and sulfides, etc., thus contributing to environmental protection.
Application of Ferro Manganese
Steel industry: Ferro manganese as deoxidizer and desulfurizer in the steelmaking industry. High-quality steel needs to be deoxidized and desulfurized during smelting, but this procedure will increase the cost of steel making. Fe-Mn is a cheap deoxidizer and desulfurizer. It can refer to the removal of harmful substances such as sulfur in steel, and effectively reducing the content of harmful elements in steel, improving the quality of steel. In the steelmaking industry, about 3 to 5kg of 75% ferro manganese is consumed per ton of steel produced.
Foundry industry: Adding ferro manganese into cast iron can be used as an inoculant and nodularizing agent for ductile iron, and can prevent the formation of carbides, promote the precipitation of graphite, shorten the spheroidization time, and greatly reduce the form of impurities in molten iron, improved cast iron properties and quality. Fe-Mn can also reduce the blockage of the smelting furnace nozzle, effectively prolonging the service life of the smelting furnace.
Other industries: High-carbon ferro manganese or manganese alloys are used as reducing agents for the production of low-carbon ferroalloys. Ferro manganese powder can be used as a suspended phase in the mineral processing industry, and used as a coating for welding rods in the welding rod manufacturing industry; high manganese ferro manganese can be used in the electrical industry to prepare semiconductor pure manganese, and in the chemical industry, it can be used to make manganese ketones, etc.

Production Process of Low Carbon Ferro Manganese
Electrosilicothermal method
The process of smelting low-carbon Ferro manganese by electric silicothermal method is to add manganese-rich ore, manganese-silicon alloy and lime into the electric furnace, mainly rely on electric heat to melt the furnace material, and refine and desiliconize manganese and silicon.
Shaking oven method
The shaking furnace method, also known as the shaking bag method, is to mix the liquid manganese-silicon alloy smelted in the submerged electric furnace and the liquid medium manganese slag into the shaking bag, and carry out strong mixing and stirring in the shaking bag to make the silicon and slag in the manganese-silicon alloy Manganese oxide reacts in the medium to carry out desiliconization and reduction of manganese. Then, the liquid manganese-silicon alloy from which part of the silicon has been removed is blended into the electric furnace together with preheated manganese-rich ore and lime to smelt low-carbon Ferro manganese.
Oxygen blowing method
Converter oxygen blowing method to smelt low-carbon Ferro manganese is to heat the liquid high-carbon Ferro manganese (containing 6.0-7.5% carbon) smelted in an electric furnace into the converter, and blow in oxygen through a top-blowing oxygen lance, or top-blown oxygen and bottom-blown Argon removes the carbon in high-carbon Ferro manganese, and at the same time, an appropriate amount of slagging agent or coolant is added. When the carbon is removed to meet the requirements of the standard (C≤0.7%), the obtained alloy is low-carbon Ferro manganese.
Blast Furnace – Refining Furnace Method
The blast furnace-refining furnace method for smelting low-carbon Ferro manganese is characterized in that: the blast furnace Ferro manganese liquid is sent into the mixed iron furnace to heat up to 1450°C-1550°C, and then mixed into the submerged side-blown refining furnace to blow oxygen for decarburization, and oxygen blowing in the early stage; In the mid-term, reduce the oxygen intensity, fill in argon, and carry out argon-oxygen mixed blowing, and the argon-oxygen ratio is 1:1; in the later stage, when the carbon drops below 0.7%, and the end temperature of manganese and iron water reaches 1750°C-1800°C, all switch to Argon, reducing atmosphere operation, adding liquid manganese-silicon alloy.
