Description
Calcium silicon alloy is a compound alloy mainly composed of silicon, calcium and iron,s calcium and silicon has a strong affinity with oxigen, especially calcium, which not only has a strong affinity with oxigen and sulfur, but also with nitrogen, so the calcium silicon is an ideal compound deoxidizer, desulfurization agent and denitrification agent.

Application
1. In the steelmaking industry, calcium alloy can be used instead of aluminum for final deoxidation, is applied to high-quality steel, special steel and special alloys production. Such as rail and low carbon steel, stainless steel, steel and nickel base alloy, titanium alloy and other special alloy.
2. In the foundry industry, it is used as a drainage agent as a tube mold powder, and is generally used as a fine powder.
3. It is used as inoculants and additives in foundries such as cast iron and cast steel. Generally, granules or 10-50mm blocks are used, and some of them are also used as inoculants.Then the block is mixed with other materials to smelt other types of multi-element alloys.
4. In the cored wire industry, it is mainly made of silicon-calcium cored wire and used as a deoxidizing and desulfurizing agent in molten steel in steel mills. This is generally used in 0-1.6mm, 0-2mm, 0-3mm and other specifications of the powder.
5. Some alloy electric furnaces also use silicon-calcium alloys when making converters or opening furnaces.
