What is calcium silicon

Calcium silicon, another name is calcium silicon alloy. It is a binary alloy composed of silicon and calcium. It also contains different amounts of impurities. For example, iron, aluminum, carbon, sulfur and phosphorus.

Calcium silicon manufacturing process:

Silicon calcium is made of quartz, limestone and coal as raw materials. Produced in submerged arc electric furnaces .

CaSi alloy can be obtained in lump or powder form. The most widely used method for intergrated steel applications is in the form of cored wire. This is mainly because calcium has low density and high reactivity in the ladle. This makes it difficult to introduce and retain it in the melt. Calcium silicon cored wire eliminates these variables.
