Top Quality Ca28Si60 Silicon Calcium Lump For Steelmaking And Casting
In steelmaking, calcium silicon is added to molten steel to remove impurities such as oxygen and sulfur. It reacts with these impurities to form stable compounds that can be easily removed from the steel. Calcium silicon also acts as an alloying agent, providing the steel with desirable properties such as increased strength and improved castability.
Function
Calcium and silicon have a strong affinity with oxygen. Especially calcium metal has a strong affinity with oxygen and has a strong affinity with sulfur and nitrogen. Therefore, calcium silicon is an ideal composite deoxidizer and desulfurizer. Silicon alloys have a strong deoxidizing ability, which helps the deoxidized products easily float and discharge, but can also improve steel’s performance in the plasticity, impact toughness, and fluidity,ductility. At present, calcium silicon alloy can replace aluminum for final deoxidation.
