ferro silicon lumps china application
Ferrosilicon lump is 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℃
