Calcium metal wire

What is Calcium Metal Wire?

Calcium metal wire is a high-purity metallic product drawn from calcium metal, typically with a minimum purity of 98.5%. It is a silver-white, highly reactive alkaline earth metal used primarily as a powerful deoxidizer and desulfurizer in steelmaking . The wire form allows for precise, automated feeding into molten steel during ladle refining processes .

Key Specifications

Main Applications

Steelmaking – Acts as a deoxidizer, desulfurizer, and inclusion modifier to improve steel cleanliness and reduce nozzle clogging in continuous casting

Cored Wire Production – Serves as the core material for calcium cored wires used in ladle refining

Specialty Steels – Essential for treating silicon-sensitive grades such as electrical steels and certain stainless steels where silicon contamination must be avoided

Alloy Production – Used in the production of calcium alloys and as a reducing agent

Advantages

High Purity – Minimum 98.5% calcium ensures efficient steel treatment

Clean Addition – No silicon or iron introduced into the melt, unlike calcium-silicon alloys

Deep Desulfurization – Achieves ultra-low sulfur levels (below 10 ppm) in specialty steel applications

Automation Compatible – Wire form enables consistent, controlled feeding into ladles
