Calcium Silicon

Calcium silicon  Mainly used as inoculant of cast iron. Silicon-calcium alloy has a strong reducing power and is also used as a deoxidizer for high-quality steel. Due to the large activity of calcium in the steelmaking temperature, the effect is not easy to stabilize, it is appropriate to add some kind of slowing agent.As a steel deoxidizer, a silicon-calcium-barium alloy, a silicon-calcium-barium-aluminum alloy, or a silicon-calcium-manganese alloy is often used.

Calcium Silicon alloy is mainly used in steelmaking and cast iron production.Calcium and silicon and oxygen affinity are great, and the deoxidation products are easy to float, easy to discharge, so the use of calcium and silicon alloy deoxidation of the liquid relatively pure, in the refining of high quality steel and special alloys, calcium-silicon alloy commonly used as deoxidizer.

Calcium and sulfur in calcium-calcium alloy to form a stable compound CaS, and CaS insoluble in the molten steel, therefore, calcium and silicon alloy deoxidation, there are desulfurization.

In cast iron production, calcium silicate is more effective than ferrosilicon to improve cast iron performance. Calcium silicate is not only an effective inoculant to promote the formation of spherical graphite, but also play a deoxy, desulfurization, denitrification and silicon effect.
