More Details About The Product


Calcium and silicon are both powerful deoxidizers. Therefore, calcium silicon is mainly used in high grade steels production as a deoxidizer and desulfurizer. Calcium Silicon can control size, shape, oxide distribution and sulfide addition, which improves several properties of the resultant products, for instance impact, ductility, machinability and fluidity. Calcium Silicon can be combined with Barium, as this chemical element works to reduce the vapor pressure and increase the density of the alloy, which also improves efficiency. It is mainly provided in powder and lump forms. Steel industry is the largest consumer of calcium silicon. Both, calcium and silicon have chemical affinity for oxygen. Calcium has chemical affinity for nitrogen and sulphur as well. Calcium Silicon alloy as a sulphide former enables sulfides distribution that minimizes chain-type inclusions.

Industries use Ferro Calcium Silicon alloy is also used for the non-metallic inclusions modification. The suspended solid inclusions of aluminium oxide are liquified by calcium. Calcium (Ca) transforms alumoinium oxide (Al203) into CaO: Al2O3). It also improves the material properties of steel. In the solidified steel, the calcium aluminates are undeformable which maintains the high isotropy of the material properties even after steel working.
