Use of SiCa

Weden Metal Co.,Limited | Updated: Jan 19, 2018

Calcium silicon alloy is a composite alloy composed of elemental silicon, calcium and iron, which is produced from about 1907 by electric silicon heating method.


Calcium silicon have a strong affinity with oxygen. Especially calcium, not only has a very strong affinity with oxygen, and sulfur and nitrogen have a strong affinity, so calcium-silicon alloy is a more ideal composite deoxidizer, desulfurizer. Silicon-calcium alloy is not only deoxidizing ability, deoxidation products easy to float, easy to discharge, but also improve the performance of steel and improve the plasticity of steel, impact toughness and fluidity.


Calcium silicon alloy can replace final deoxidation of aluminum and is used in the production of high-quality steel, special steel and special alloy such as steel, mild steel, stainless steel and other special alloys such as nickel base alloy and titanium base alloy. Calcium silicate is also suitable as a warming agent for converter steelmaking plants, as an inoculant for cast iron and as an additive in ductile iron production.
