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.Silicon in the steel industry used as deoxidizer and alloying agents. 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, so it is 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 (including Si0.30-1.8%), spring steel, tool steel (including Si0.40-2.896) and transformer silicon steel (2.81 4.896) containing silicon, ferrosilicon alloy agent 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.Silicon 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.Silicon has been used as a reductant can also be used as a 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 the ferroalloy industry are frequently used in low-carbon ferroalloy production of an article also.

Ferrosilicon is often used in the high-temperature smelting process of magnesium metal in the Pijiang process, and the magnesium in CaO.MgO is replaced, and about 1.2 tons of ferrosilicon is consumed for each ton of magnesium metal, which plays a great role in the production of magnesium metal.The ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. In the welding rod manufacturing industry can be used as welding rod coating. High-silicon ferrosilicon is used in the chemical industry to make products such as silicone.

Because silicon and oxygen are easy to combine into silicon dioxide, so iron silicon is often used in steelmaking as a deoxidizer, at the same time due to the generation of SiO2 release a lot of heat, at the same time deoxidation, it is also beneficial to improve the temperature of molten steel. At the same time, ferrosilicon can also be used as an alloying element additive, widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in ferroalloy production and chemical industry, commonly used as a reducing agent.This application case uses powder tablet method to prepare samples, the process is simple and controllable, the personnel operation requirements are very low, without any chemical reagents, safety and environmental protection.The prepared sample is determined by the EDX9000B spectrometer, which is tailor-made for the analysis of ferrosilicon by Infx Scientific Instruments. The test accuracy is high, the analysis speed is fast, and the results can be matched with traditional chemical methods.
