What is Ferromanganese

Ferromanganese is mainly composed of manganese and iron. Adding ferromanganese into molten steel can pass through the oxide slag insoluble in molten steel with ferrous oxide and float on the surface of molten steel. At the same time, the affinity between manganese and sulfur is greater than that of manganese and iron. Adding molten steel can form manganese sulfide with a high melting point with sulfur and transfer it into the slag, which effectively improves the enforceability and rollability of steel. Ferromanganese is the most widely used ferroalloy in the iron and steel industry.

High-carbon ferromanganese is mainly used in steelmaking to improve the hardness and toughness of steel, and effectively deoxidize it in the steelmaking process. High-carbon ferromanganese is a necessary smelting raw material for many special steel products, but for the production of high-carbon ferromanganese, The method is little known. In fact, the production method of high-carbon ferromanganese is mainly the blast furnace method. The production of high-carbon ferromanganese by blast furnace method is one of the more common production methods. The production method is basically the same as that of casting pig iron. Manganese and iron are extracted from ore, but the difference is that ferromanganese steelmaking has some special rules, which are the basic institutional basis for the establishment of blast furnace ferromanganese production operations!

The main ferroalloy raw materials for high-carbon ferromanganese production are manganese ore, coke, flux, and combustion-supporting air or oxygen-enriched. The raw materials are loaded into the furnace from the top of the furnace, and high-temperature air or oxygen-enriched air 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 molten slag and metal accumulate at the bottom of the furnace and pass through the slag port, Tapping the slag and tapping the iron at regular intervals. With the melting, reaction and discharge of the charge, and the continuous addition of new charge, the production is carried out continuously.
