Raw materials for ferromanganese
Ferromanganese is an iron alloy composed of manganese and iron. Manganese has a high affinity with oxygen. When added to molten steel, it can form oxide slag insoluble in the molten steel with the ferrous oxide in the steel. The binding force between manganese and sulfur is also greater than that between iron and sulfur. Sulfur is added to molten steel to form manganese sulfide and converted into slag for discharge.
Ferromanganese can improve the forgeability and tieability of steel, and increase the wear resistance, hardness and strength of steel. Therefore, it is the most commonly used ferroalloy as a deoxidizer and desulfurizer in steelmaking.
Generally speaking, ferromanganese is a ferroalloy composed of manganese and iron. The raw materials for its production are manganese ore, coke, and lime, which are produced through a high-temperature melting reaction. Ferromanganese contains a certain amount of carbon because of the addition of lime. According to the carbon content of manganese Iron is divided into low carbon ferromanganese, medium carbon ferromanganese, and high carbon ferromanganese. The most used in casting is high carbon ferromanganese with a manganese content of more than 65. It has deoxidation effect, high quality, and relatively cheap price. Even some steel plants Will choose 65 high carbon ferromanganese
