DESCRIPTION
Ferro Silicon is used for: Steelmaking and foundries as a source of silicon in production of carbon steels, stainless steels, and other ferro alloys for its deoxidizing properties. Used in manufacturing silicon steel for electro-motors and transformer cores. It is used for inoculation of the iron. To prevent loss of carbon from the molten steel. In arc welding, ferro silicon can be found in some electrode coatings.

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.74.0-80.0
