Calcium silicon use/manufacturers

Jan 25, 2021 / 131 views

Calcium silicon is a binary alloy composed of silicon and calcium, belonging to the category of ferroalloy. Its main components are silicon and calcium, and it also contains different amounts of iron, aluminum, carbon, sulfur and phosphorus. The common granularity is 10-100mm, 10-80mm or custom granularity

Silicon calcium is a kind of ideal compound deoxidizer and desulfurizer, which is widely used in steelmaking, low carbon steel, stainless steel and the production of special alloys such as nickel base alloy and titanium base alloy. The main uses of calcium silicon are:


(1) Both calcium and silicon have a strong affinity with oxygen, which is an ideal compound deoxidizer and desulfurizer. Silicon alloy not only has strong deoxidization ability, deoxidization product is easy to float up, easy to discharge, but also can improve the performance of steel, improve the plasticity, impact toughness and fluidity of steel.

(2) Si-Ca alloy is also suitable for the converter steel workshop with the warming agent, Si-Ca alloy can also be used as cast iron inoculant and ductile iron production of additives.
