Product Features
High Penetration Depth: Rigid cold-rolled steel sheath allows the wire to pierce through heavy slag layers without premature melting, releasing calcium at the bath floor.
Reduced Splashing: Iron-diluted calcium matrix lowers vapor pressure during injection (2 to 4 m/s), significantly reducing melt turbulence and alloy loss.
Liquid Inclusion Control: Transforms hard alumina (Al2O3) and manganese sulfide (MnS) into low-melting-point liquid calcium aluminates, preventing submerged entry nozzle blockage.
Hermetic Overlap Seam: Precision folded seam locks the powder tight, eliminating feed jams caused by dust leakage and protecting active calcium from humidity.
Applications
Secondary Ladle Refining: Suitable for Ladle Furnace (LF) and RH vacuum degassing units.
Continuous Casting Lines: Designed for long-sequence casting of aluminum-killed steels without tundish nozzle clogging.
High-Grade Steel Alloys: Ideal for pipeline steel (API X70/X80), automotive sheet, bearing steel, and high-strength structural rebar.
Customization Options
Core Ratio: Custom Ca/Fe proportions (Ca28/Fe72, Ca30/Fe70, Ca35/Fe65) or specialized multi-element formulations.
Physical Sizes: Non-standard sheath thicknesses (0.30 mm - 0.60 mm) and wire diameters tailored to unique feeding machines.
Payout Options: Vertical internal decoiling (eye-to-sky) or horizontal axle decoiling setups based on plant mill layout.
Manufacturing & Quality Control
Raw Material Testing: Spectrographic analysis (XRF) on every raw batch to keep impurity levels low (Sulfur, Phosphorus, Carbon ≤ 0.03%).
In-Line Mass Monitoring: Real-time load-cell tracking during powder filling maintains uniform weight distribution (±2.0 g/m).
Seam Integrity Checks: Continuous tensile testing ensures high column strength, preventing sheath splitting inside high-speed feeding equipment.
Batch Traceability: Every coil is tagged with a unique production heat/lot number linked directly to factory quality inspection records.

FAQ
Q: What calcium recovery rate does CaFe Cored Wire achieve compared to pure calcium wire?
A: CaFe Cored Wire typically reaches a 15%–25% calcium recovery rate in ladle refining, compared to 8%–12% for pure calcium wire, thanks to reduced vaporization and deeper bath penetration.
Q: How does this product prevent nozzle clogging during continuous casting?
A: It converts solid alumina (Al2O3) particles into liquid calcium aluminates that remain fluid at steelmaking temperatures (around 1550°C), allowing liquid steel to flow smoothly through the tundish nozzle.
Q: What is the recommended wire feeding speed for 13mm wire?
A: Standard injection speeds range from 2.0 m/s to 4.0 m/s, depending on ladle depth, bath temperature, and slag thickness.
Q: How do you prevent powder leakage and oxidation during sea freight?
A: We combine a cold-rolled double-lock seam for total powder containment with vacuum-sealed PE wrapping, anti-corrosion desiccants, and a protective outer steel cage.
Q: What is the shelf life of the wire in warehouse storage?
A: Stored in its original unopened export packaging in a dry, covered facility, the wire retains full metallurgical activity without oxidation for up to 12 months.
Q: Is this wire compatible with standard automatic feeding machines?
A: Yes. Coil dimensions and payout configurations are standardized to fit major twin-strand feeding systems, including Afansyev, Danieli, and Paubert models.
