What is silicon calcium powder

1 Silicon calcium alloy is composed of elements silicon, calcium and iron composite alloy, is a more ideal compound deoxidizer, desulfurization agent. It is widely used in the production of high quality steel, low carbon steel, stainless steel and special alloys such as nickel base alloy and titanium base alloy. It is suitable to be used as a warming agent for converter steelmaking workshop. It can also be used as inoculant of cast iron and additive in ductile iron production. Silicon-calcium alloys have been produced by the electrosilicothermal process since about 1907.

2 Uses

Both calcium and silicon have a strong affinity with oxygen. Calcium, in particular, not only has a strong affinity with oxygen, but also has a strong affinity with sulfur and nitrogen. So calcium-silicon alloy is a kind of ideal compound gel oxygen agent, desulfurization agent. Silicon alloy not only has strong deoxidation ability, deoxidation products are easy to float, easy to discharge, but also can improve the performance of steel, improve the plasticity of steel, impact toughness and fluidity. 

At present, silicon calcium alloy can replace aluminum for final deoxidation. Applied to high quality steel. Special steel and special alloy production. For example, rail steel, low carbon steel, stainless steel and other steel grades and special alloys such as nickel base alloy and titanium base alloy, can be used as silicon calcium alloy as a deoxidizer. Calcium-silicon alloy is also suitable for use as a warming agent for converter steel workshop, calcium-silicon alloy can also be used as inoculant of cast iron and additive in ductile iron production.
