Description      

Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy smelted in an electric furnace with coke, scrap steel, quartz (or silicon dioxide) as raw materials.Ferro silicon is made by smelting coke, steel scraps, and quartz (or silica) in a submerged arc furnace. Commonly used ferro silicon grades are Fesi70%, FeSi72%, FeSi75%.

Specification

Uses

1. Silicon and oxygen are easily synthesized into silicon dioxide. Therefore, ferro silicon is often used as a deoxidizer in steelmaking. At the same time, since SiO2 emits a lot of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing.

2. Ferro silicon is used as an alloying element additive. It is widely used in low-alloy structural steel, composite steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.

3. Ferro silicon is used in ferroalloy production and chemical industry. Often used as a reducing agent. The silicon content is 95% 9%.
