Ferro-Silicon is used both as a deoxidizer and for alloying purposes in the production of steel. Silicon promotes graphitization


Ferro Silicon has a lower density than FeMn and much lower than FeCr and lies in second place by tonnage. It can be used for both refinement and addition. The raw material used to produce FeSi is high grade quartz very common throughout the world; however the biggest cost of producing FeSi is power. Large and cheap sources are usually hydro-electric and unfortunately not a stable source as it is dependant on rainfall, snowfall and thawing. Ferro Silicon is the workhorse deoxidizer in steel production and iron foundries, its consumption is in a more or less fixed ratio to steel production at about 5lb per tonne.
