鉄とシリコンのフェロシリコン合金で構成されています. フェロシリコンはコークスです, スクラップスチール, 石英 (またはシリカ) 原料として, 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, 等.

加えて, 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. 特にダクタイル鋳鉄, 鋼の機械的特性またはそれに近い機械的性能. 鋳鉄に一定量のシリコンを添加すると、鉄の生成を防ぐことができます, 黒鉛の析出と炭化物の球状化を促進します。, したがって、球状鉄の生産において, フェロシリコン接種剤は重要な黒鉛沈殿物の一種です (ヘルプ) シリコンは還元剤として使用されており、合金鉄の製造にも使用できます。. シリコンと酸素の化学的親和性が非常に大きいだけではありません, 高シリコンフェロシリコンの炭素含有量は非常に低いです. 非常に高いシリコンフェロシリコン (またはケイ質合金) 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. 同時に, 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.
