What is the use of silicon calcium alloy?

Calcium and silicon have a strong affinity with oxygen. In particular, calcium has a strong affinity not only with oxygen, but also with sulfur and nitrogen. Therefore, silicon calcium alloy is an ideal composite adhesive oxygen agent and desulfurizer. Silicon alloy not only has a strong deoxidation ability, the deoxidation product is easy to float and discharge, but also can improve the performance of steel, improve the plasticity, impact toughness and fluidity of steel. At present, silicon calcium alloy can replace aluminum for final deoxidation. It is used in the production of special steels and special alloys. For example, steel grades such as rail steel, low-carbon steel, stainless steel and special alloys such as nickel-based alloys and titanium-based alloys can all use silicon calcium alloy as a deoxidizer. Silicon calcium alloy is also suitable as a warming agent for converter steelmaking workshops. Silicon calcium alloy can also be used as an inoculant for cast iron and an additive in ductile iron production.
