High-carbon ferromanganese is an alloy material with various properties. It is widely used as a deoxidizer and silicon-manganese alloy additive. The carbon element in high-carbon ferromanganese can improve the strength and hardness of steel, and the manganese element can improve the corrosion resistance of steel.

The main ferroalloy materials used in the production of high-carbon ferromanganese are manganese ore, coke, and flux, as well as combustion-supporting air or oxygen-rich. The raw materials are loaded into the furnace from the top of the furnace. High-temperature air or rich oxygen is blown into the furnace through the tuyere so that the coke is burned to obtain high temperature and reducing gas to reduce the ore. The melted slag and metal accumulate at the bottom of the furnace and pass through the slag port. , The taphole discharges slag and iron regularly. As the charge is melted, reacted, and discharged, the new charge is added continuously, and the production is carried out continuously.
