Description

Calcium silicon alloy is a compound alloy made up of elements silicon, calcium, and iron, is an ideal compound deoxidizer, desulfurization agent. At present calcium alloy can be used instead of aluminum for final deoxidation, is applied to high-quality steel, special steel and special alloys production.

Application

Silicon Calcium (CaSi) is mainly used for deoxidization, degassing and sulfur fixation of liquid steel.There is a strong exothermic effect when silicon calcium is added into molten steel. Calcium turns into calcium vapor in molten steel, which stirs the molten steel and is beneficial to the floating of nonmetallic inclusions. After deoxidation, the shape of non-metallic inclusions is easy to change. Therefore, silicon calcium alloy is used to produce clean steel, high-quality steel with low oxygen and sulfur content, and special performance steel with extremely low oxygen and sulfur content.
