Fair Price Ca28Si60 Silicon Calcium Lump For Steelmaking Indispensable Raw Materials
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.
In steelmaking, calcium silicon is added to molten steel to remove impurities such as oxygen and sulfur. It reacts with these impurities to form stable compounds that can be easily removed from the steel. Calcium silicon also acts as an alloying agent, providing the steel with desirable properties such as increased strength and improved castability.
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.

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.
Aluminum industry: Calcium silicon is also used in aluminum alloys. It helps refine the structure of aluminum and improves its mechanical properties, such as strength and ductility.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
