Product Description

High efficiency new composite silicon calcium alloy in steelmaking 

Calcium silicon is also called calcium silicon alloy or ferro silicon calcium. It is a composite alloy mainly composed of silicon and calcium. As a ferroalloy, it also contains different impurities such as iron, aluminum, carbon, sulfur, and phosphorus. It has the form of a lump or powder.
High Efficiency New Composite Silicon Calcium Alloy in Steelmaking
Calcium Silicon is a potent deoxidizer and desulfurizer utilized in the production of high grade steels. Although Silicon itself is a powerful deoxidizer, Calcium is by far more powerful. In addition, Calcium Silicon 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.
Calcium Silicon is also utilized in combination with Barium. The Barium increases the density and reduces the vapor pressure of the alloy, thereby improving efficiency. In cast irons it is used mainly by Pipe Shops for the purpose of coating the inside of each mono cast machine.
Calcium Silicon 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 a low density and high reactivity in the ladle making it difficult to introduce and retain in the melt. Cored wire eliminates these variables: CaSi powder is blown deep into the steel melt through immersion of steel tubes.

Product Applications
Calcium and silicon have a strong affinity with oxygen. Especially calcium metal has a strong affinity with oxygen and has a strong affinity with sulfur and nitrogen. Therefore, calcium silicon is an ideal composite deoxidizer and desulfurizer. Silicon alloys have a strong deoxidizing ability, which helps the deoxidized products easily float and discharge, but can also improve steel's performance in the plasticity, impact toughness, and fluidity,ductility. At present, calcium silicon alloy can replace aluminum for final deoxidation.
It is used in the production of steels with different grades and special alloys. It can also be used as an inoculant and additive in the cast iron industry.
1. Compound deoxidizer and desulfurizer.
2. Heating agent used in converter steelmaking workshop.
3. It can be used as an inoculant for cast iron.
4. As an additive to produce ductile iron.
