Product Introduction of Calcium Silicon:
1. Calcium Silicon is an alloy composed of calcium, silicon, iron and other elements, and widely used and largely produced of iron alloy.
2. Calcium,silicon and oxygen have a strong affinity. Especially calcium, not only has a strong affinity with oxygen and sulfur, nitrogen, but also has very strong affinity. So the Si Ca alloy is a kind of ideal composite deoxidizer and desulfurization agent.
3.With the traits of easy to float, easy to exhaust, it improves the performance of steel, enhances the ductility, impact toughness and flowability of steel.
4. At present, calcium silicon alloy can replace the aluminum for final deoxidization.
Advantages
1.CaSi ferroalloy is compound alloy which is composed of silicon,calcium and ferro.
2.It is an ideal compound deoxidizer and desulfurizer which can be used in the production of many kinds of steel such as rail steel,low carbon steel,stainless steel and other special alloy like Ni base alloy and titanium base alloy.
3.CaSi ferroalloy also can be applied as the heatraiser in convertor steelmaking workshop and as the inoculant or additive in producing cast iron and nodular cast.
4.Si and Ca can be controlled absolutely.
5.chalking resistance.
6.slightly less content of other impurities such as C,S,P,Al
7.not easy to be deliquesced
Applications
Absorbent for liquids and gases in industrial processes.
In road construction
As a refractory material in industrial furnaces
For the insulation of pipes and conduits, insulation boards
in the manufacture of paints and other types of coating materials
Cosmetics, pharmaceutical products, such as antacids
Fertilizers and insecticides

Other information
Calcium Silicon is also utilized in combination with Barium. The Barium increases the density and reduces the vapor pressure 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 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: CaSi powder is blown deep into the steel melt through immersion of steel tubes.
