Silicon Calcium CaSi Alloy

The main components of silicon calcium alloy are silicon and calcium, and different amounts of impurities such as Fe, Al, C, S, P etc. Calcium has a strong affinity with oxygen, sulfur, hydrogen, nitrogen and carbon in molten steel. So, silicon calcium alloys are usually used as a deoxidizer and desulfurizer.

In addition, silicon calcium is added to molten steel to produce a strong exothermic effect, which is beneficial to maintain the temperature of molten steel. The calcium vapor produces a stirring effect on the molten steel, which is beneficial to the floating of non-metallic slag.

Product Features

In the production of cast iron, calcium silicon is more effective in improving the properties of cast iron than ferrosilicon. Silicon-calcium alloy is not only an effective inoculant to promote the formation of spheroidal graphite, but also has the effects of deoxidation, desulfurization, denitrification and silicon increase.
