Ferro Silicon is a essential element in
the manufacture of steel and, in fact, is known as the 'bridesmaid
of the steel industry' since it has no substitute. It is used
primarily as an additive for deoxidation and also as an alloying
element.
It is produced by the reduction of quartz (SiO2) in a submerged
arc electric furnace using carbon as the reducing agent. The
most widely used form of carbon are charcoal, coal, and coke.
Like in Ferro / Charge Chrome, the molten alloy is tapped
from the furnace hearth at regular intervals and then processed
for despatch to the customers who include most of the well
known names.
