Unveiling the Versatility of Ferro Silicon 75

The raw materials for producing 75% ferrosilicon are mainly coke, steel scraps, and quartz stone, which are heated and smelted in an electric furnace. Ferrosilicon 75% is widely used in casting and steelmaking. It is mainly used as an inoculant and spheroidizing agent in the casting industry and as a deoxidizer in the steelmaking industry.

It can improve the strength, hardness and corrosion resistance of steel and plays a major role in the production of magnesium metal.

Specifications of ferrosilicon 75

1.Used for steelmaking
Ferrosilicon 75 is a deoxidizer and alloying agent in the steelmaking industry. In order to ensure the quality of steel and obtain steel with qualified chemical composition, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a powerful deoxidizer in steelmaking, used for precipitation deoxidation and diffusion deoxidation. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of the steel.

2.Used in ductile iron
75% ferrosilicon is commonly used as an inoculant and spheroidizing agent in the cast iron industry. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in the iron and promote the precipitation and spheroidization of graphite.

3.As alloy reducing agent
FeSi 75 is used as a reducing agent in ferroalloy production. High silicon ferrosilicon is a commonly used reducing agent in the production of low carbon iron alloys due to the high chemical affinity between silicon and oxygen and the low carbon content of high silicon ferrosilicon.

4.Used in metallurgy
Ferrosilicon 75% is commonly used in magnesium smelting by the gold metal method and is added during the high-temperature smelting process of magnesium metal. For every ton of magnesium metal produced, approximately 1.2 tons of ferrosilicon are consumed to replace the magnesium in CaO.MgO. Ferrosilicon plays a large role in the production of magnesium metal.
