Ferro Silicon FeSi Deoxidizer

Ferrosilicon is a ferro alloy product made of coke, steel scraps, and quartz (or silica) smelted in an electric furnace.Ferrosilicon is mostly used as deoxidizer in steel making or casting, and it can also be used as alloying element additives, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.

Product Features

Since silicon and oxygen are easily combined to produce silicon dioxide, ferrosilicon is used as a deoxidizer in steelmaking production. When the silicon in the ferrosilicon combines with oxygen, a large amount of heat is released due to the formation of SiO2, which is also beneficial to increase the temperature of the molten steel while deoxidizing.

Application and After-Sales Service

1.Ferro silicon is widely used as deoxidizer and alloy additive in steelmaking.
2.Ferro silicon powder emits a lot of heat in steel making production, and is used as a heating agent for steel ingot caps to improve the quality and recovery rate of steel ingots.
3.Ferrosilicon can be used as an inoculant and nodulation agent for cast iron.
4.High silicon content ferrosilicon alloy is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.
5.Ferrosilicon powder or atomized ferrosilicon powder can be used as coating for welding rod production.
6.Ferrosilicon can be used for high-temperature smelting of magnesium metal. 1 ton of metallic magnesium needs to consume about 1.2 tons of ferrosilicon.
