DESCRIPTION
Ferrosilicon is an ferroalloy composed of silicon and iron. Ferrosilicon is an ferrosilicon alloy made of steel chips, coke and quartz, which is smelted by electric furnace. Because oxygen and silicon are extremely easy to combine into silicon dioxide, so ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, due to the more heat emitted by the generation of SiO2, it is also more favorable to improve the temperature of molten steel at the same time of deoxidation.
The use of ferrosilicon: in the steel industry, is an indispensable deoxidizer; High silicon ferrosilicon or siliceous alloy in the ferroalloy industry for the production of low carbon alloy reducing agent; Adding ferrosilicon to cast iron can prevent the formation of carbide from iron, promote graphite precipitation and spheroidization, and have the role of inoculant and spheroidization agent.
Ferrosilicon Application
1. In the steelmaking process, ferrosilicon is often used as a deoxidizer.
2. Ferrosilicon can also be used as a connecting agent for alloying elements, widely used in low-alloy steels and non-alloy steels
Ferrous metal, bearing steel, heat-resistant steel, electrical silicon steel.
3.Ferrosilicon can be used as a reducing agent in ferroalloy production and chemical industry.
4. Ferrosilicon can be used as inoculant and nodularizer in the steel industry.
