Product description

Silicon calcium powder is widely used in the production of low carbon steel, stainless steel and other steel grades and special alloys such as nickel-based alloys and titanium-based alloys. and additives in the production of ductile iron.

Calcium silicon powder production method:

The method of producing calcium silicon powder is generally the use of electro-silicon thermal method.

Silicon calcium alloy application
Both calcium and silicon have a strong affinity for oxygen. Calcium, in particular, not only has a strong affinity with oxygen, but also has a strong affinity with sulfur and nitrogen. Therefore, silicon-calcium alloy is an ideal composite colloidal oxygen agent and desulfurizer. Silicon alloy not only has strong deoxidation ability, and the deoxidized products are easy to float and discharge, but also can improve the properties of steel, and improve the plasticity, impact toughness and fluidity of steel. At present, silicon-calcium alloys can replace aluminum for final deoxidation. Special steels and special alloys are produced. For example, steel grades such as rail steel, low carbon steel, stainless steel, and special alloys such as nickel-based alloys and titanium-based alloys can all use silicon-calcium alloys as deoxidizers. Silicon-calcium alloy is also suitable as a warming agent for converter steel refining workshop. Silicon-calcium alloy can also be used as an inoculant for cast iron and an additive in the production of ductile iron.
