Calcium silicon production

Silicon calcium, also known as silicon calcium 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.

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

Calcium silicon lump and 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 manufacturing process

1. High-content silicon calcium alloy products, mainly produced by electrode furnace


a : It can produce silicon-calcium alloy products with higher specification content.

b: The product quality is stable and the impurities are less.

2. Medium and low content silicon calcium alloy products, mainly produced by medium frequency furnace.


a : Mainly produces medium and low specification silicon calcium alloy products.

b: The production cost is low, and the output can be flexibly controlled.

Silicon calcium 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. The warming agent used in the converter steel workshop.

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

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