THE ROLE OF FERROSILICON IN STEELMAKING
In steelmaking, ferrosilicon is used for:
1. Product performance Ferrosilicon is a convenient way of adding silicon as an alloying element, to improve various properties of the final steel.
2. Slag reduction In the manufacture of stainless steels, the presence of silicon reduces chromium oxides in the melt, improving the recovery of metallic chromium.
3. Deoxidation Ferrosilicon provides quick-acting removal of oxygen from the melt, so avoiding the presence of inclusion-forming oxides and avoiding loss of desirable elements.
4. Fuel Some steel mills add ferrosilicon to the melt so that it can be burnt off to get heat into the furnace, and so reduce energy costs.

(1) Ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. (2) Used as an inoculant and spheroidizing agent in the cast iron industry. In the production of nodular cast iron, 75 ferrosilicon is an important inoculant (helping to precipitate graphite) and nodulizer. (3) Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is great, but the carbon content of high-silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or silicon alloy) is a commonly used reducing agent in the production of low-carbon iron alloys in the ferroalloy industry.

Ferro Silicon Ferro Silicon has a melting point of 1200�¯�¿�½?�?�°C to 1250�¯�¿�½?�?�°C with a boiling point of 2355�¯�¿�½?�?�°C and Ferro Silicon contains about 2% of calcium and alluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.
We are exporter of Ferro Silicon. FerroChrome is a kind of Ferro alloy which is formed by Ferro and Chrome,it is an important alloy addition in steel making. Ferrochrome (Fe Cr) is an alloy of chromium and containing between 50% and 70% chromium.
