Ferrosilicon / fesi alloy smelting

ferrosilicon is made of coke, steel chips, quartz (or silica) and is smelted in an electric furnace.In the traditional smelting process of iron and steel Talent net, the silicon is reduced from the silica containing SIO2.Most smelting of ferrosilicon USES metallurgical coke as reducing agent, and steel chip is the regulator of ferrosilicon.

The production of a ton of ferrosilicon requires the consumption of raw materials:

Silica: 1780-1850kg.

Coke: 890-930kg.

Steel chips: 220-230kg.

Electrode paste: 45-55kg.

Power consumption: 8400-9000kwh/t.

ferro silicon lumps china application

Ferrosilicon lumpis widely used in steel industry, casting industry and other industrial production.

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

High silicon iron or silicon alloys are used as reductants in the production of low carbon ferroalloys in the ferroalloy industry.Ferrosilicon can be used as an inoculant for ductile cast iron, and can prevent the formation of carbide, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron.

In addition, ferrosilicon powder can be used as suspension phase in mineral processing industry, and as coating for welding electrode in welding electrode manufacturing industry.High silicon ferrosilicon can be used to produce pure silicon of semiconductor in electrical industry, and can be used to produce silicone in chemical industry.

In the steelmaking industry, about 3 to 5kg75% ferrosilicon is used per ton of steel produced.

Melting point: 75SiFe is 1300℃
