Casi Powder is a calcium silicon alloy powder used as a deoxidizer, desulfurizer, and alloy additive in steelmaking and foundry applications. It improves steel cleanliness, inclusion modification, and metallurgical efficiency.

Parameter

product-673-383

Applications

Carbon Steel Production – Used as a deoxidizer and desulfurizer to improve steel cleanliness and reduce oxygen content.

Special Alloy Steel Manufacturing – Modifies non-metallic inclusions to enhance mechanical properties and process stability.

Cast Iron Foundries – Functions as an alloy additive to improve melt quality and casting consistency.

Secondary Steel Refining (LF Furnace) – Applied during ladle refining to optimize inclusion morphology and sulfur removal.

Ferroalloy Production – Used as a raw material or alloying additive in selected metallurgical production processes.
