Manganese iron particles, as a type of ferroalloy, have a wide range of applications in the metallurgical industry. Especially in the steelmaking process, manganese iron particles are widely used as deoxidizers and alloy additives. This is because ferromanganese contains a high amount of manganese, which can help remove harmful elements such as oxygen and sulfur from steel during the steelmaking process, thereby improving the quality of steel. Specifically, the uses of manganese iron particles include:

1. Deoxidizer: During the steelmaking process, manganese iron particles can help remove oxygen from the steel, reduce oxides in the steel, and thus improve the purity and mechanical properties of the steel. ‌

2. Alloy additives: Manganese iron particles can also be used as alloy additives to improve the physical properties of steel, such as hardness and toughness, by adjusting the chemical composition of the steel to meet different usage needs. ‌
In addition, the use of manganese iron particles can also reduce the blockage of the smelting furnace water outlet and extend the service life of the smelting furnace. In the casting industry, manganese iron particles are also used as inoculants and spheroidizers for ductile iron, which can promote the precipitation of graphite and improve the quality and performance of cast iron.
