What Is Ferro Silicon Used For? What Is The Price Of Ferrosilicon Per Ton?

Ferrosilicon is an iron-silicon alloy made from coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace.

Since silicon and oxygen easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking.

At the same time, since SiO2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing.

Ferro alloy can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.

Ferroalloys is often used as a reducing agent in ferroalloy production and chemical industry.

Ferro silicon uses:Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final stage of steelmaking.

The chemical affinity between silicon and oxygen is very large, so ferro silicon alloy is a strong deoxidizer for steelmaking for precipitation and diffusion. deoxidation.

Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of the steel.

Therefore, when smelting structural steel (containing 0.40-1.75% silicon), tool steel (containing SiO.30-1.8%), spring steel (containing SiO.40-2.8%) and silicon steel for transformers (containing 2.81-4.8% silicon) , fesi is also used as an alloying agent.

At the same time, improving the shape of inclusions and reducing the content of gas elements in molten steel is an effective new technology to improve steel quality, reduce costs, and save iron.
