Product Description
Seamless Pure Calcium Cored Wire for Steelmaking
Advanced metallurgical solution for efficient calcium treatment in steel production, featuring 9mm diameter and 98% pure calcium core for superior inclusion modification.
Product Overview
Our seamless pure calcium cored wire is engineered to optimize calcium absorption during steelmaking processes. The composite design ensures stable calcium content with minimal evaporation loss, making it ideal for producing high-quality refined steel products.
Key Metallurgical Properties
- Calcium melting point: 850°C
- Calcium boiling point: 1480°C
- Calcium density: 1.55g/cm³
- Core composition: ≥98% pure calcium
- Wire diameter: 9±0.25mm
- Calcium content: 52g/m
Technical Specifications
| Parameter | Specification |
|---|---|
| Main Composition | Ca ≥ 98% |
| Diameter | 9 ± 0.25mm |
| Addition Amount | 0.35-0.4kg/ton steel |
| Feeding Speed | 1.5-2m/s |
| Outer Sheath | 08 aluminum steel strip |
Process Advantages
- High calcium recovery rate with minimal consumption
- Stable residual calcium content with small fluctuations
- Reduced adsorption of harmful gases (H, N)
- Long storage stability without performance degradation
- Bottom feeding capability for deeper molten steel penetration
Inclusion Modification Benefits
Transforms Al₂O₃ inclusions into liquid CaO·Al₂O₃ or CaO·Al₂O₃·CaS compounds that easily float to the surface, reducing nozzle clogging and improving castability.
Optimal Application: Ideal for IF steel, SPHC, SPHD, and other special steel grades requiring precise calcium treatment.
Recommended Usage Parameters
For optimal results: maintain residual calcium content at 30-40ppm, target Ca/Al ratio of 0.13-0.20, and adjust feeding speed based on ladle size and steel composition.
