CaSi alloy is the compound alloy which is composed by silicon, calcium and ferrum. It' s an ideal compound deoxidizer and desulfurizer which can be widely used in the production of steels such as high-quality steel, low-carbon steel, stainless steel and special alloys such as nickel base alloy, titanium base alloy. CaSi alloy can also be applied as the heat-raiser for converter steelmaking, the inoculant for cast iron production and addictive for nodular cast iron production.
Calcium Silicon Advantages
■ Stable reaction and easy operation
■ Uniform chemical composition and low impurities with high performance
■ Products can meet the needs of most customers with varied specifications.
Calcium-silicon can be used to protect the coatings of foundry pipelines used for centrifuge casting. It is also used in welding powder and pyrotechnics.
It is mainly used in the form of filled cable but also as grains for powder injection.
Calcium Silicon Uses
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.
