The export price of ferrosilicon made in China continues to rise
A lack of supply in the spot market, coupled with heavy purchases by Chinese steelmakers, has sent ferrosilicon prices soaring. Currently, China's export prices have generally risen by about $30- $60.
Ferrosilicon is a ferroalloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel scrap, quartz (or silica) as raw materials and smelted in an electric furnace. Because silicon and oxygen can be easily synthesized into silicon dioxide, ferrosilicon is often used in steelmaking as a deoxidizer, and because SiO2 generation gives off a lot of heat, while deoxidizing, it is also beneficial to raise the temperature of the steel. At the same time, ferrosilicon can also be used as an alloying element adding agent, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in the production of ferroalloys and chemical industry, commonly used as a reducing agent.
Ferrosilicon alloys are widely used in steel and casting industries.
Silicon content in the range of 8.0% to 95.0% of silicon and iron composition of ferroalloys, containing about 50% silicon ferrosilicon, mainly used for cupola melting iron silicon; containing about 75% silicon ferrosilicon commonly used as cast iron inoculant and inking agent, steelmaking deoxidizer and silicon materials; silicon and oxygen between the chemical affinity is very large, easily synthesized into silicon dioxide, so ferrosilicon is commonly used in steelmaking for deoxidizer (precipitation deoxidation and diffusion deoxidation). At the same time, ferrosilicon can also be used as an alloying element to join the agent, widely used in low-alloy structural steel, spring steel, shaft Chemicalbook bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in the production of ferroalloys and chemical industry, commonly used as a reducing agent. 2, in addition to boiling steel and semi-sedimentation steel, the content of silicon in steel should not be less than 0.10%. Silicon does not form carbides in steel, but is a solid solution in ferrite and austenite. Silicon improves the strength of the solid solution in steel and cold working deformation hardening rate is extremely strong, but reduces the toughness and plasticity of steel; the effect of steel hardenability is medium, but can improve the tempering stability of steel and oxidation resistance, so ferrosilicon is used as an alloying agent in the steelmaking industry.
