the role of ferromanganese
Ferromanganese is a kind of ferroalloy containing high manganese ore. In steelmaking, the main function of ferromanganese is to increase the hardness and wear resistance of steel. Manganese can combine with oxides to reduce the formation of iron oxide, and at the same time, it can also reduce the influence of sulfur on iron and improve the temperature toughness of steel. In addition, ferromanganese can also reduce bubbles and impurities in steel and improve the quality and strength of steel. Therefore, ferromanganese is one of the essential alloys in the manufacture of high strength steel and wear-resistant steel.
the role of ferrosilicon
Ferrosilicon is an iron alloy containing high silicon ore. The main function of ferrosilicon in steelmaking is to improve the toughness and ductility of steel. Silicon can reduce the melting point of steel and slow down the solidification rate of steel, thus making steel more ductile and plastic. At the same time, silicon can also inhibit the influence of oxygen, sulfur and other elements in steel and reduce the formation of bubbles and impurities. Therefore, ferrosilicon is also one of the essential alloys in the manufacture of cold-rolled and cold-drawn steels that require excellent plasticity and toughness.
the difference between ferromanganese and ferrosilicon in function
Ferromanganese and ferrosilicon have different functions in steelmaking. Ferromanganese is mainly used to improve the hardness and wear resistance of steel, while ferrosilicon is mainly used to improve the toughness and ductility of steel. Therefore, their application fields are also different. Ferromanganese is mainly used to make high-strength steel and wear-resistant steel, while ferrosilicon is mainly used to make cold-rolled and cold-drawn steel and other steels that need excellent plasticity and toughness.
