Ferromanganese
Ferromanganese is a type of alloy composed of iron and manganese, often with small amounts of other elements such as carbon and silicon. It is commonly used in the production of steel to improve its strength, hardness, and durability. Ferromanganese is produced through the smelting of manganese ore, iron ore, and coke in a blast furnace, resulting in a material with high manganese content that is essential for the steelmaking process.
