Calcium Silicon Alloy
Calcium silicon, also known as CaSi, is a type of alloy made from a combination of calcium, silicon, and other trace elements. It is typically used in the steel and foundry industries for a variety of applications.
Silicon-calcium alloy is an ideal composite deoxidizer and desulfurizer. It is used in the production of high-quality steel, low-carbon steel, stainless steel and other special alloys such as nickel-based alloys and titanium-based alloys. It is also suitable as a warming agent for converter steelmaking, and can also be used as an inoculant and Additive in the production of ductile iron. Both calcium and silicon have a strong affinity for oxygen. Especially calcium, not only has a strong affinity with oxygen, but also has a strong affinity with sulfur and nitrogen, so silicon-calcium alloy is an ideal composite deoxidizer and desulfurizer.

Application and Features of Calcium Silicon Alloy
- The iron and steel industry uses calcium silicon alloys as calcium additives, deoxidizers, desulfurizers and denaturants for non-metallic inclusions. It is used as an inoculant and denaturant in the cast iron industry. In steelmaking, calcium silicon is added to molten steel to improve its strength, durability, and corrosion resistance. It also helps to deoxidize the steel and remove impurities, resulting in a higher-quality product. Additionally, it can be used as a desulfurizing agent to reduce the sulfur content of the steel.
- In the foundry industry, calcium silicon is used as a nodulizer in the production of ductile iron. It helps to promote the formation of graphite nodules, which are spherical structures that give the iron its ductility and strength. It can also be used as an inoculant to improve the quality and consistency of cast iron.
- Calcium silicon is also used as a nodulizer in the casting industry, particularly in the production of ductile iron. It promotes the formation of graphite nodules, which are spherical structures that give the iron its ductility and strength. It can also be used as an inoculant to improve the quality and consistency of cast iron.
- In addition to its role as a deoxidizer and nodulizer, calcium silicon can also be used as a desiccant in steelmaking. It is particularly effective in removing moisture from the steelmaking process, which can help to reduce defects in the final product.
- Calcium silicon alloy not only has strong deoxidation ability, and the deoxidized products are easy to float and discharge, but also can improve the performance of steel, and improve the plasticity, boxing toughness and fluidity of steel.
- Calcium silicon alloy can replace aluminum for final deoxidation, and is used in the production of high-quality steel, special steel and special alloys.
- For rail steel, low-carbon steel, stainless steel and other special alloys such as nickel-based alloys and titanium-based alloys, calcium silicon alloys can be used as deoxidizers.
- Calcium silicon alloy is also used as a warming agent for converter steelmaking workshops. And as an inoculant for cast iron and an additive in the production of ductile iron.
