65%-75% Ferro Manganese As Metallurgical Industry Additives
Ferromanganese is an alloy composed of iron (Fe) and manganese (Mn). It is primarily used as a deoxidizing and alloying agent in the production of steel. The composition of ferromanganese can vary, but it typically contains around 75% to 80% manganese and 15% to 20% iron.
The production of ferromanganese involves the smelting of manganese ore, iron ore, and coke in a blast furnace or an electric arc furnace. The high temperatures in these furnaces facilitate the reduction of manganese and iron oxides, resulting in the formation of the ferromanganese alloy.

Applications
Steel Production: Ferromanganese is primarily used as an alloying agent in the production of steel. It is added to molten steel during the steelmaking process to impart desirable properties. The addition of ferromanganese helps improve the hardenability, tensile strength, toughness, and abrasion resistance of steel. It also aids in deoxidizing the molten steel, removing impurities such as oxygen and sulfur, and enhancing the overall quality of the steel.
Foundry Industry: Ferromanganese is used in the foundry industry as a nodularizer and desulfurizing agent. It helps improve the castability and mechanical properties of iron castings by promoting the formation of graphite nodules and reducing the sulfur content in the molten iron.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
