Calcium-silicon

Calcium-silicon , also known as CaSi alloy. It belongs to the category of ferroalloys. The main chemical components are silicon and calcium. It also contains impurities such as iron, aluminum, carbon, sulfur, etc.Calcium silicon(CaSi) is a silicon-calcium alloy obtained from silica, lime, and coke in a strong reducing atmosphere at 1500-1800 degrees.

 Its main components are silicon and calcium, and it also contains impurities such as iron, aluminum, carbon, sulfur, and phosphorus in varying amounts. In the iron and steel industry, it is used as a calcium additive, deoxidizer, desulfurizer, and denaturant for non-metallic inclusions. It is used as an inoculant and denaturant in the cast iron industry.

Calcium-silicon

There are two forms of Calcium-silicon lump and calcium-silicon powder.

The most widely used method for integrated steel applications is in the form of Cored Wire It is the silicon calcium core wire we often say. Calcium has a low density in the ladle and is highly reactive, so it is difficult to introduce and keep in the melt. The core wire eliminates these variables.

Calcium-silicon Features:


1. Calcium silicon has a strong deoxidation capacity, deoxidation products are easy to float and easy to discharge.

2. Ca-Si alloy can improve the performance of steel to improve plasticity of steel, impact toughness, and mobility.

3. Calcium silicon alloy is used to control the shape, size, and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility, and impact properties of the final product.

4. Silicon calcium alloy has chalking resistance.

5. CaSi is not easily deliquescent.
