calcium silicon alloy

Calcium silicon alloy is a composite alloy composed of silicon, calcium and iron elements. It is an ideal composite deoxidizer and desulfurizer. In steel making industry, silicon calcium alloy is used as calcium additives, deoxidizers, desulfurizers and non-metallic inclusions. It is used as inoculant and denaturing agent in cast iron industry. In addition, on the basis of silicon calcium alloy, adding other elements to form a ternary or multi-component composite alloy such as Si-Ca-Al, Si-Ca-Mn, Si-Ca-Ba.


There are many calcium silicon alloy advantages in steel making and casting industry. For example, it is widely 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. The Calcium Silicon Alloy Advantages as following:
◆Calcium and silicon have a strong affinity to oxygen, especially calcium, not only has a strong affinity with oxygen, but also has strong affinity with sulfur and nitrogen. Therefore, silicon calcium alloy is an ideal compounding agent and desulfurizer.
◆The silicon calcium alloy not only has strong deoxidation ability, but also the deoxidation product is easy to float and discharge. So it can improve the performance and plasticity of the steel as well as improve the impact toughness and fluidity of the steel.
◆Calcium silicon alloy is also suitable used as warming agent for converter steel workshops; it can also be used as an inoculant for cast iron and an additive in the production of ductile iron.

Because there are so many advantages for calcium silicon alloy, the calcium silicon price will be relatively high compared with other ferro alloys.
