Calcium Silicon is a potent deoxidizer and desulfurizer utilized in the production of high grade steels. Although Silicon itself is a powerful deoxidizer, Calcium is by far more powerful. In addition, Calcium Silicon 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.

Calcium and Silicon both have a strong chemical affinity for oxygen. Especially calcium, have a strong chemical affinity not only for oxygen, but also for sulphur and nitrogen.
That is why Silicon-Calcium Alloy usually works as an desirable complex deoxidant and desulphurizer.
Silicon-Calcium has a strong deoxydation, separating the deoxidized matters easily from the oxide of calcium and silicon, thus the desired matters are easily discharged and obtained. This method can greatly raise the performance of steel in terms of plasticity, toughness and liquidity.
Currently Silicon-calcium alloy can replaces aluminum to accomplish the task of final deoxydation, and is used in the production of fine steel, special steel and special alloy. For example, to turn out rail steel, mild steel, stainless steel, and special alloys such as nickel-based alloy and titanium-based alloy, which can be adopted Silicon-calcium alloy as deoxidant. Silicon-calcium alloy can also work as temperature-gaining agent in convertor steel making workshop , and as catalyst in production of cast iron, as well as the additive in the production of nodular cast iron.
Calcium Silicon is also utilized in combination with Barium. The Barium increases the density of the alloy, thereby improving efficiency. In cast irons it is used mainly by Pipe Shops for the purpose of coating the inside of each mono cast machine.
Calcium Silicon can be obtained in lump, crushed or powder form. The most widely used method for intergrated steel applications is in the form of cored wire. This is mainly because calcium has a low density and high reactivity in the ladle making it difficult to introduce and retain in the melt. Cored wire eliminates these variables.
