Product Description

  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, while the generation of SiO2 due to the release of a large amount of heat, in the deoxidation at the same time, the temperature of the steel is also beneficial to improve. 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.

Specification

Application

1.In the steel making field, Ferro silicon is used as deoxidizer and alloying agent to precipit and diffuse deoxidation.Adding a certain amount silicon of fe-si to the steel can obviously improve the strength ,hardness ,elasticity and permeability of steel.

2.In the iron casting,ferro silicon is used as ball mile agent and alloying agent especially in the nodular iron casting, Addingferro silicon to cast iron ,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing.

3.High-silicon ferro silicon can be used as reductant for producing the low-carbon alloy in ferro alloy industry.

4.In addition, ferro silicon powder can be used as a suspended phase in the mineral processing industry and coatings for welding electrodes in the electrode manufactruing.
