Market Price Metallurgical Grade Ca31Si60 Ca28Si60 Ferro Silicon Calcium Lump/Powder/Granules

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 alloying agent in the steelmaking industry.

In cast iron production, calcium silicon is more effective than ferrosilicon for improving cast iron properties. This alloy serves as both an effective inoculant for spheroidal graphite formation and provides deoxidation, desulfurization, denitrification, and silicon enhancement benefits.

Calcium and silicon exhibit strong affinity with oxygen, particularly calcium which also bonds strongly with sulfur and nitrogen. This makes calcium silicon an ideal composite deoxidizer and desulfurizer. The alloy's strong deoxidizing capability helps remove impurities while improving steel's plasticity, impact toughness, fluidity, and ductility. Calcium silicon can effectively replace aluminum for final deoxidation.

Available particle sizes: 10-100mm, 10-50mm, 0-3mm, 2-6mm, or custom granularities to meet specific requirements.

Steelmaking: Added to molten steel to enhance quality and performance through:

• Deoxidizer: Reacts with oxygen to reduce impurities and improve steel cleanliness and mechanical properties
• Alloying agent: Introduces calcium and silicon to modify composition, enhancing strength and castability

Aluminum industry: Used in aluminum alloys to refine structure and improve mechanical properties including strength and ductility.

Dark gray luster material packaged in polyethylene plastic bags with 10-100mm granularity. Each bag contains net weight of 1000KG (gross weight 1003KG).
