99.95% Silicon Calcium Granule For Steelmaking Deoxidizer

99.95% Silicon Calcium Granule For Steelmaking Deoxidizer

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.

Apart from its use in steelmaking, calcium silicon is also utilized in the production of other alloys, including aluminum alloys, as well as in the manufacturing of certain types of batteries. It is a versatile material that plays a crucial role in various industries where the modification and refinement of metals are required.

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.

Si-Ca alloy is mainly composed of silicon and calcium elements. Ca content was 24- 31%, Si content was 55- 65%.

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.

• 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.

• Foundry applications: Calcium silicon can be used in foundry applications, where it acts as a deoxidizer and desulfurizer in the production of cast iron. It helps remove impurities and improve the quality of the castings.

Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
