Calcium silicon alloy

Specification:

Product Introduce:

Calcium-Silicon Alloys are used as deoxidizer and desulfurizer in the manufacturing of high  steel. Indeed, 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. The steel industry accounts for around 90 % of global CaSi consumption.

The alloy is also used for the modification of non-metallic inclusions. 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 steel 

product. The calcium liquefies the suspended solid inclusions of aluminium oxide), a principal source of fatigue failure in 

highly stressed alloy steels, that are always present in aluminum-killed steels(Al203 is transformed by Ca into CaO:Al2O3). 

Furthermore, the material properties of steel are improved: the calcium aluminates formed are largely undeformable  in the

solidified steel and allow high isotropy of the material properties to be maintained after working of the steel.

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: CaSi powder is blown deep 

into the steel melt through immersion of steel tubes.
