Ferro manganese is a ferroalloy primarily composed of manganese and iron, and it plays a critical role in the steelmaking and metallurgical industries. With its robust properties and various applications, it stands as a vital component in modern manufacturing and industrial processes.
Ferro manganese is produced through a smelting process in blast furnaces or electric arc furnaces, where manganese ore (often combined with iron ore) is reduced with carbon (usually in the form of coke). The typical composition includes:
This combination results in an alloy with high durability and the ability to deoxidize and desulfurize steel.
