Product Description
CALCIUM SILICON 58/30 GRAIN 1-3MM
Silicon calcium alloy is mainly used for deoxidization, degassing and sulfur fixation of liquid steel.There is a strong exothermic effect when silicon calcium is added into molten steel. Calcium turns into calcium vapor in molten steel, which stirs the molten steel and is beneficial to the floating of nonmetallic inclusions. After deoxidation, the shape of non-metallic inclusions is easy to change. Therefore, silicon calcium alloy is used to produce clean steel, high-quality steel with low oxygen and sulfur content, and special performance steel with extremely low oxygen and sulfur content.
In the production of cast iron, besides deoxidation and purification,it also plays a role of inoculation, which helps to form fine or spherical graphite, makes graphite evenly distributed in gray cast iron, reduces the tendency of white cast iron, and increases silicon, desulfurizes and improves the quality of cast iron.

In the secondary refining technology of steel,the content of oxygen and sulfur in steel can be reduced to a very low level by using calcium silicon alloy powder or core wire for deoxidation and desulfurization.
The form of sulfide in steel can be controlled and the utilization rate of calcium can be improved.
Available Size of ferro silicon calcium alloy powder:
0-2mm,0-3mm,0-10mm customizable.
Si-Ca alloy is a good Compound Deoxidizer.
Both calcium and silicon have strong affinity for oxygen. Calcium,in particular,has a very strong affinity for oxygen, as well as sulfur and nitrogen.
As a result deoxidation ability of Calcium silicon alloy is strong,and the deoxidation products are easy to float up and discharge.
We also process silicon calcium cored wire, please send us your specific requirements, we can customize according to customer requirements.
Packing:
1mt/1.25mt/25kg/50kg bags
