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.

  • Ferro silicon Calcium is presently imported to meet the necessities in the country.
  • Ferro silicon calcium alloy is a composite alloy composed of silicon, calcium and iron. It is commonly used as deoxidizer and desulfurizer in steel smelting.
  • Ferro Silicon Calcium can be used as a substitute for Ferro Silicon and Ferro Manganese when added to make different types of steel
  • Calcium and silicon have a strong affinity with oxygen. Especially calcium, not only has a strong affinity with oxygen, but also with sulfur, nitrogen has a strong affinity.
  • So the Ferro calcium silicon alloy is an ideal compound deoxidizer and desulfurizer It is applied to the production of high-quality steel, special steel and special alloy, such as calcium silicon alloy can be used as deoxidizer in the production of rail steel, low carbon steel, stainless steel and other steel and nickel-based alloys, titanium- based alloys and other special alloys.
  • Ferro silicon calcium alloy is also suitable for the converter steel-making workshop as the warming agent, and cast iron's inoculant and additives in the nodular cast iron production.
