99.95% Silicon Calcium Lump Non Ferrous Metal Material For Casting Additives
Calcium Silicon is compound alloy which is composed of silicon, calcium and ferro. It is an ideal compound deoxidizer and desulfurizer which can be used in the production of many kinds of steel such as rail steel, low carbon steel, stainless steel and other special alloy like Ni base alloy and titanium base alloy. CaSi alloy also can be applied as the heatraiser in convertor steelmaking workshop and as the inoculant or additive in producing cast iron and nodular cast iron.
The main components of calcium silicon are calcium (Ca) and silicon (Si). Calcium is a reactive, silvery-white alkaline earth metal, while silicon is a non-metallic element with a grayish color. When combined, calcium and silicon form a compound known as calcium silicide (CaSi2). The composition of calcium silicon can vary depending on the specific requirements of its application, but it typically contains around 30-35% calcium and 55-65% silicon.
Calcium Silicon function
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.
Specification

Applications
Steelmaking: Calcium silicon is added to molten steel to improve its quality and performance. It serves multiple purposes in the steelmaking process:
Deoxidizer: Calcium silicon reacts with oxygen in the molten steel, reducing the oxygen content and removing impurities. This helps enhance the steel's cleanliness and mechanical properties.
Alloying agent: Calcium silicon serves as an alloying agent by introducing calcium and silicon into the steel. This helps modify the steel's composition and improves its strength, castability, and other desired characteristics.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
