Ferro silicon
Ferro Silicon is produced by reduction of silica or sand with coke in presence of scrap iron, Mill scale, or other source of iron. Ferro Silicon with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferro Silicon with higher silicon content is made in electric arc furnaces. The usual formulations on the market are Ferro Silicon with 15%, 45%, 75%, and 90% silicon. The remainder is iron, with about 2% consisting of other elements like Aluminum and calcium
- Application:
Ferrosilicon can be used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys.
It can be used to manufacture other Ferroalloys, of silicon, corrosion- resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores.
Ferrosilicon is used for inoculation of the iron to accelerate graphitization, In the manufacture of cast iron.
Ferrosilicon is a basis for manufacture of FYe-alloys like magnesium ferrosilicon and is also important as an additive to cast irons for controlling the initial content of silicon.
Ferrosilicon is also used in the"Pidgeon" process to make magnesium from dolomite.
Military is also using Ferro silicon to quickly produce hydrogen for balloons by the ferrosilicon method
