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.
