Pure Calcium Cored Wire
Pure Calcium Cored Wire is a high-performance secondary metallurgy consumable engineered for deep-melt calcium injection. By delivering solid, ultra-pure calcium directly into liquid steel without introducing iron powder or unwanted tramp elements, it optimizes inclusion morphology (turning solid Al₂O₃ into liquid calcium aluminates), minimizes nozzle clogging, and improves castability.

Key Technical Advantages
No Tramp Element Addition: Eliminates iron powder or foreign fillers to maintain strict liquid steel purity standards.
Deep-Melt Penetration: High-density pure calcium core reaches the bottom of the ladle before vaporization, increasing calcium yield over CaFe wires.
Alumina Inclusion Modification: Reacts directly with solid Al₂O₃ inclusions to form liquid calcium aluminates (12CaO·7Al₂O₃), preventing tundish nozzle clogging.
High-Speed Feeding Integrity: Cold-rolled steel sheath prevents wire buckling, breaking, or premature seam opening at feeding speeds up to 250 m/min.
Targeted Applications
Steelmaking Processes: Ladle Refining Furnace (LRF), RH Degasser, Continuous Casting (CC).
Critical Steel Grades: Bearing steel, pipeline steel (API grades), spring steel, high-strength low-alloy (HSLA), and automotive structural steel.

FAQ
Q: What is the calcium recovery rate compared to standard CaFe cored wire?
A: Pure calcium wire offers deeper melt penetration before vaporization, typically delivering a calcium recovery rate between 20% and 30% depending on ladle depth and feeding speed.
Q: What feeding speed is recommended for this cored wire?
A: It operates reliably on standard automatic wire feeders at speeds between 120 m/min and 250 m/min, depending on melt temperature and ladle height.
Q: How do you prevent internal calcium oxidation during ocean transit?
A: Each coil is sealed with a moisture-proof PE inner liner, desiccants, and outer shrink wrapping to eliminate humidity exposure and prevent core degradation.
Q: How is coil dimensional tolerance controlled for automated pay-off systems?
A: Wire diameter tolerance is kept strictly within ±0.2 mm, and coil outer/inner diameters are customized to prevent line jamming in automated feeding cages.
Q: What is the typical lead time for a standard 20ft container order?
A: Standard specifications ship within 10–15 business days following order confirmation and deposit receipt.
