Use Of Ferro Silicon And Main Producing Areas
Silicon and oxygen easily synthesize silica. Therefore, Ferrosilicon is often used in steelmaking as Deoxidation agent, at the same time because of the SiO2 generated by the release of a lot of heat, at the same time deoxidation, to improve the temperature of molten steel is also advantageous. Ferrosilicon is used as alloying element addition agent. Widely used in low alloy structural steel, bonded steel, spring steel, bearing steel, heat-resisting iron and electrical silicon Steel, outside Ferrosilicon in ferroalloy production and chemical industry, commonly used as reducing agent. The silicon content reaches 95% 99%. Pure silicon is commonly used to manufacture monocrystalline silicon or to prepare non-ferrous metals.
Ferrosilicon is widely used in steel industry, foundry industry and other industrial production. Ferrosilicon is an essential deoxidation agent in steelmaking industry. In the torch Steel, Ferrosilicon is used to precipitate deoxidation and diffusion deoxidation. Brick iron is also used as an alloy for steelmaking. Adding a certain amount of silicon in steel can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel and reduce the hysteresis loss of transformer steel. General steel containing silicon 0.15%-0.35%, structural steel containing silicon 0.40%~1.75%, the tool steel contains Silicon 0 30%~1.80%, the spring steel contains silicon 0 40%~2.80%, stainless steel containing silicon 3.40%~4.0%, Silicon steel silicon 1.00%~3.0%, silica containing silicon $number or higher.Ferro Silicon
High silicon ferrosilicon or silicon alloy is used as reducing agent in ferroalloy industry to produce Low-carbon Ferroalloy. Ferrosilicon can be used as a inoculant of ductile iron, and can prevent carbide formation, promote the precipitation and spheroidal graphite, and improve the performance of cast iron. In addition, Ferrosilicon powder in the mineral processing industry can be used for suspension, in the welding rod manufacturing electrode coating; High silicon ferrosilicon can be used in the electrical industry to prepare semiconductor pure silicon, in the chemical industry to make silicon ketone, etc. In the steelmaking industry, each production of a tons of steel consumes 3~5kg75% ferrosilicon.Ferro Silicon
Major domestic production areas: Northwest (Gansu, Qinghai, Ningxia) Inner Mongolia, Southwest (Sichuan, Guizhou). Export profile: Mainly exported to Japan, Korea, the United States, Taiwan and other countries or regions. China has become the world's main production of Ferrosilicon and the world's main supplier of Ferrosilicon, in addition to Norway, Russia, Brazil and other countries Ferrosilicon production is also very large.Ferro Silicon
