Product Description

Is composed of iron and silicon ferrosilicon alloy. Ferrosilicon is coke, scrap steel, quartz (or silica) as raw material, made of electric furnace smelting iron silicon alloy. 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.

(1) used as deoxidizer and alloying agents 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 improve the inclusion shape to reduce gas elements content in liquid steel, is to improve the steel quality, reduce cost, save with iron effective new technology. Especially for continuous casting molten steel deoxidized requirements, the practice has proved that not only meet the requirements of steelmaking deoxidization, ferrosilicon is than major, and with the desulfurization performance of strong penetrating power, etc.

In addition, in the steel industry, the use of ferrosilicon powder at high temperature burning can release a large number of hot this characteristic, often used as a compound ingot cap so as to increase the recovery rate and the quality of ingot.

(2) in the cast iron industry as a nucleating agent and spheroidizing agent. Cast iron is a kind of important modern industrial metal materials, it is much cheaper than steel, easy to melt refining, with excellent casting performance and seismic capacity is far better than steel. Especially the nodular cast iron, its mechanical performance at or near the steel mechanical property. Add a certain amount of silicon in cast iron can prevent iron in formation, promote the precipitation of graphite and carbide spheroidizing, therefore in nodular iron production, ferrosilicon inoculants is a kind of important graphite precipitation (help) and spheroidizing agent.

(3) used as a reductant in ferroalloy production. Not only the chemical affinity between silicon and oxygen is very big, and the carbon content of high silicon ferrosilicon is very low. So high silicon ferrosilicon (or siliceous alloy) is in ferroalloy industry are frequently used in low-carbon ferroalloy production a reducing agent.

(4) 75 # ferrosilicon smelting magnesium was numerically simulated in commonly 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.

(5) USES in other ways. Mill or treated atomized ferrosilicon powder, can be used as a suspension phase in the mineral processing industry. Can be used as electrode coating in the electrode manufacturing. High silicon ferrosilicon in the chemical industry can be used in the manufacture of silicone products.

In these USES, steel industry, foundry industry and ferroalloy industry is the biggest user of ferrosilicon. They are about more than 90% of the total consumption of ferrosilicon. In all kinds of different type of ferrosilicon, the most widely used is 75% ferrosilicon. In the steel industry, 1 t steel consumes about 3-5 per production kg75 % ferrosilicon.
