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.
It is used in the production of steels with different grades and special alloys. It can also be used as an inoculant and additive in the cast iron industry.
1. Compound deoxidizer and desulfurizer.
2. Heating agent used in converter steelmaking workshop.
3. It can be used as an inoculant for cast iron.
4. As an additive to produce ductile iron.
