Special Material Ferro Silicon

Ferro silicon is also a well-known alloying element in the industry. But do you really know that much about the characteristics of ferrosilicon? Ferrosilicon is an indispensable element in steelmaking. Poor steelmaking effect may be useless against ferrosilicon. What is so special about ferrosilicon that is unknown? In a word, ferrosilicon is a widely used ferroalloy variety. It is an iron-silicon alloy composed of silicon and iron in a certain proportion, and is an indispensable material for steelmaking, such as FeSi75, FeSi65, and FeSi45.

1.Why is ferro silicon indispensable in steelmaking? Due to the strong affinity between silicon and oxygen, after adding ferrosilicon to steelmaking, the following deoxidation reaction occurs: 2FeO + Si = 2Fe + SiO₂ silica is the product of deoxidation, it is lighter than molten steel, floating on the surface of steel into the slag, thereby removing the oxygen in the steel, which can significantly improve the strength, hardness and elasticity of the steel, improve the permeability of the steel, and reduce the hysteresis loss of the transformer steel.

2.What are the other uses of ferro silicon? used as inoculant and nodularizing agent in the cast iron industry; When smelting some ferroalloy products, ferrosilicon is added as a reducing agent; Due to the important physical properties of silicon, such as low electrical conductivity, poor thermal conductivity and strong magnetic conductivity, ferrosilicon is also used as an alloying agent in silicon steelmaking. Ferrosilicon is often used in the high-temperature smelting process of magnesium metal in the Pijiang magnesium smelting process. Other uses. Finely ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as a coating for welding rods in the electrode manufacturing industry. High-silicon ferrosilicon can be used in the chemical industry to make products such as silicone.
