Introduction to Calcium Iron Cored Wire
Calcium Iron Cored Wire, also known as CaFe cored wire, is an alloy cored wire made by mixing 28%-35% calcium particles with 65%-72% iron powder, encased in a cold-rolled low-carbon steel strip. It is widely used in steelmaking for calcium treatment to enhance steel purity and reduce inclusions. This guide covers its specifications, benefits, and why it’s essential for modern steel production.
What is Calcium Iron Cored Wire?
Calcium Iron Cored Wire is designed to address challenges in steel refining. Calcium, a strong deoxidizer, has low density and melting point, causing it to vaporize quickly in molten steel. By combining it with iron powder in a steel sheath, the wire sinks deeper into the melt, ensuring effective deoxidation, desulfurization, and inclusion removal without splashing or furnace damage.

Why Use Calcium Iron Cored Wire?
Calcium Iron Cored Wire solves the issue of calcium evaporation in molten steel. The iron powder increases density and melting temperature, allowing the wire to reach optimal depths for reaction. This method improves steel anisotropy by preventing sulfide inclusion formation, as noted in steelmaking research from sources like the American Iron and Steel Institute (external link). It also reduces costs by enhancing alloy yield and minimizing metal waste.
Advantages of Calcium Iron Cored Wire
- Deoxidation and Desulfurization: Effectively removes oxygen and sulfur from molten steel.
- Inclusion Control: Modifies inclusions to improve steel ductility and toughness.
- Cost Efficiency: Increases rare earth element yield and stabilizes composition, lowering refining expenses.
- Safety: Minimizes splashing and extends furnace life compared to raw calcium addition.
