Calcium silicon product introduction

Silicon calcium is not called calcium silica. It is a binary alloy composed of silicon and calcium. So, it is also known as silicon calcium alloy.The calcium content is 22%-35%, and the silicon content is 55%-65%. It also contains different amounts of impurities. For example, iron, aluminum, carbon, sulfur and phosphorus.

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.

Silicon calcium is made of quartz, limestone and coal as raw materials. It is produced in submerged arc electric furnaces . It is mainly used as a incubator for cast iron. Silicon calcium alloy has a strong reduction ability and is also used as an oxygen at high-quality steel. As a deoxidizer of steel, SiCaBa alloy or SiAlBaCa alloy, or SiCaMn alloy is mostly used.

Calcium Silicon specifications:

Specification	Chemical Component%

Calcium silicon uses:

1.Composite deoxidizer, desulfurizer. Mainly used for high grade steel. The silicon calcium alloy has strong deoxidation ability. The deoxidation product is easy to float and is easy to discharge. It also improves the properties of steel and improves the ductility of steel.

2.As an additive in the production of ductile iron.

3.Can be used as an inoculant for cast iron.

4.The warming agent used in the converter steel workshop.
