Product Overview/产品概述:
Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made by smelting in an electric furnace using coke, steel scraps, and quartz (or silica) as raw materials. Since silicon and oxygen can easily synthesize silicon dioxide, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since a large amount of heat is released when SiO2 is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. 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 the chemical industry. Ferrosilicon is widely used in the steel industry, foundry industry and other industrial production.
Product Introduction/产品介绍:
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 improve the strength, hardness and elasticity of the steel, increase the magnetic permeability of the 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 0.30%-1.80% silicon, spring steel contains 0.40%-2.80% silicon, 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 siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low-carbon ferroalloys. Ferrosilicon can be used as an inoculant for ductile iron when added to cast 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 suspended phase in the mineral processing industry and as a coating for welding rods in the welding rod manufacturing industry; high-silicon ferrosilicon can be used in the electrical industry to prepare semiconductor pure silicon and in the chemical industry to manufacture silicone, etc.
In the steelmaking industry, approximately 3 to 5kg of 75% ferrosilicon is consumed for each ton of steel produced.
