Silicon calcium can also be called the calcium silicon alloy, there is an alloy of silicon, calcium, the iron is mainly a component, generally use more extensive place is in the steel industry, because this is a very useful desulfurization, deoxidizer, effect is very good, so the utilization rate is very high, generally in the * * * * * * the production of steel, mild steel, stainless steel is very common.And suitable for use as a warming agent for converter steel workshop;It can also be used as inoculant for cast iron and additive in the production of ductile iron. 

Both calcium and silicon have a strong affinity for oxygen.Calcium, in particular, has a strong affinity not only with oxygen, but also with sulfur and nitrogen.Therefore, silica-calcium alloy is an ideal compound oxygen agent and desulfurizer.Silicon alloy not only has strong deoxidizing ability, deoxidizing product is easy to float up and discharge, but also can improve the properties of steel, plasticity, impact toughness and fluidity of steel.At present, silicon and calcium alloys can replace aluminum for final deoxidation.
