Silicon calcium alloy is a composite alloy composed of elements silicon, calcium and iron, and is an ideal composite deoxidizer and desulfurizer. It is widely used in the production of high-quality steel, low-carbon steel, stainless steel and other steel grades and special alloys such as nickel-based alloys and titanium-based alloys; it is also suitable as a warming agent for converter steel refining workshops; it can also be used as an inoculant for cast iron. and additives in the production of ductile iron.

Advantages of Calcium silicon
1. Calcium silicon has a strong deoxidation capacity, deoxidation products are easy to float and easy to discharge.
2. Ca-Si alloy can improve the performance of steel to improve the plasticity of steel, impact toughness and mobility.
3. Calcium silicon alloy is used to control the shape, size and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility and impact properties of the final product.
4. Ferro silicon calcium has chalking resistance.
5. Si-Ca is not easily deliquescent.
