Ferrosilicon is an iron alloy made of iron and silicon. Ferrosilicon is made from coke, steel, quartz (or silica), and smelt made from an electric furnace. Because the silicon is easy to combine with oxygen to form silicon dioxide, so time of ferrosilicon is often used in steelmaking deoxidizer, because of SiO2 is generated at the same time gives off a lot of heat, at the same time of DNA, to improve the temperature of molten steel is also good. Ferrosilicon, meanwhile, also can be used as an alloy element joining agent, widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, silicon in the ferroalloy production and chemical industry, commonly used as a reducing agent.

Used as a deoxidizer and alloying agent in the steel industry. In order to obtain qualified chemical composition and guarantee the quality of steel, in the last stage of the steel must be solid, chemical affinity between silicon and oxygen is very big, therefore is silicon steel strong deoxidizer used in sedimentation and diffusion deoxidation. Add a certain amount of silicon in the steel, can significantly improve the strength of steel, hardness and elasticity, thus in smelting steel (0.40 1.75%) containing silicon, tool steel (including the SiO. 30-1.8%), spring steel (containing the SiO. 40-2.8%) and transformer silicon steel (2.81 4.8%) containing silicon, ferrosilicon alloy used to use. At the same time, it is effective to improve the quality of steel, reduce cost and save iron.It is especially suitable for continuous casting of molten steel. It has been proved that the silicon iron can not only meet the requirements of steelmaking and deoxidization, but also has the advantages of desulphurization and high penetrating power.

In addition, in the steelmaking industry, the use of silicon iron powder in high temperature can release a lot of heat, which is often used as the heating agent of the steel ingot to improve the quality and recovery of the ingot.

Used as reducing agent in ferroalloy production. It is not only the chemical affinity between silicon and oxygen, but also the low carbon content of silicon silicon. Therefore, high silicon ferrosilicon (or silicon alloy) is a common reductant in the production of low carbon iron alloys in ferroalloy industry.

75 # ferrosilicon smelting magnesium was numerically simulated in the frequently used in the process of high temperature smelting metal magnesium, CaO. Magnesium replacement of MgO style, each with a ton of magnesium production is 1.2 tons of silicon, metal magnesium production plays a big role

Other USES. Finely ground or atomized silicon iron powder can be used as suspension phase in mineral processing industry. Coating of welding rod in welding rod manufacturing. High silicon silicon is used in chemical industry to make products such as silicone.

In these USES, the steelmaking industry, foundry industry and ferroalloy industry are the largest users of silicon iron. They consume more than 90 per cent of the iron. Of the various sizes of silicon iron, the most widely used is 75% silicon. In the steelmaking industry, each production of 1t steel consumes about 3 to 5kg75% of silicon iron.

Granularity and packaging:

Natural block 1 ton or 0.5t tonnage bag, powder products with 25kg woven bag endometrial moisture-proof packaging supply, plus 1 ton or 0.5 ton large bags, tons of plastic woven bags, can also be supplied according to the user requirements.
