ISO9001 Ca28Si60 Silicon Calcium Powder For Steelmaking Additives
Calcium silicon, also known as calcium silicide, is an alloy composed of calcium, silicon, and traces of other elements. It is primarily used as a deoxidizer, desulfurizer, and an alloying agent in the steelmaking industry.
Calcium Silicon function
Calcium Silicon alloy mainly composed of Si and Ca.
It mainly used as calcium additives, deoxidizer, desulfurizer and non-metallic inclusion denaturant in steelmaking. It also can be used as inoculant for cast iron.
Specification
| Grade | Ca(≥) | Si | Al(≤) | C(≤) | S(≤) | P(≤) |
| Ca31Si60 | 31 | 55-65 | 2.4 | 1.0 | 0.05 | 0.04 |
| Ca28Si60 | 28 | 55-65 | 2.4 | 1.0 | 0.05 | 0.04 |
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.
Desulfurizer: Calcium silicon reacts with sulfur in the steel, reducing the sulfur content. It helps control the level of sulfur, which can negatively affect the steel's quality and properties.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
