Ferrosilicon is a ferroalloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made by smelting coke, steel shavings, and quartz (or silica) in an electric furnace. Since silicon and oxygen are easily combined into silicon dioxide, ferrosilicon is often used as a deoxidizer in steelmaking.

 

At the same time, because SiO2 generates a lot of heat, it is also beneficial to increase the temperature of molten steel during deoxidation. At the same time, ferrosilicon 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. Ferrosilicon is often used as a reducing agent in ferroalloy production and chemical industry.

 

Ferrosilicon is made by smelting coke, steel shavings, and quartz (or silica) in an electric furnace. When ferrosilicon is traditionally refined, silicon is reduced from silica containing SIO2.

 

Ferrosilicon smelting mostly uses metallurgical coke as a reducing agent, and steel scrap is a regulator of ferrosilicon.

 

Production of one ton of ferrosilicon raw material and power consumption are:

 

Silica: 1780-1850kg

 

Coke: 890-930kg

 

Steel shavings: 220-230kg

 

Electrode paste: 45-55kg

 

Power consumption: 8400-9000kwh/t

 

Ferrosilicon is widely used in steel industry, foundry industry and other industrial production

 

Ferrosilicon is an essential deoxidizer in the steelmaking industry. In Torch Steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly increase the strength, hardness and elasticity of steel, increase the magnetic permeability of steel, and reduce the hysteresis loss of transformer steel. General steel contains 0.15%-0.35% silicon, structural steel contains 0.40%-1.75% silicon, tool steel contains silicon 0.30%-1.80%, spring steel contains silicon 0.40%-2.80%, and stainless acid-resistant steel contains Silicon 3.40% ~ 4.00%, heat-resistant steel contains silicon 1.00% ~ 3.00%, silicon steel contains silicon 2% ~ 3% or higher.

 

High-silicon ferrosilicon or silicon alloys are used as reducing agents in the production of low-carbon ferroalloys in the ferroalloy industry. Adding ferrosilicon to cast iron can be used as an inoculant for ductile iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron.

 

In addition, ferrosilicon powder can be used as a suspension phase in the beneficiation industry, and as a coating for welding rods in the electrode manufacturing industry; high-silicon ferrosilicon can be used to prepare semiconductor pure silicon in the electrical industry, and can be used to manufacture silicone in the chemical industry.

 

 

In the steelmaking industry, about 3-5kg of 75% ferrosilicon is consumed for each ton of steel produced.
