Global shipping experience – safely delivered to over 20 countries
Case Study: Calcium Cored Wire for a Mid-Sized Steel Mill in Southeast Asia
Background
A steel mill in Vietnam producing construction-grade rebar and billet was struggling with inconsistent calcium recovery and frequent nozzle clogging during ladle treatment. Their existing cored wire supplier delivered varying powder density, leading to:
Calcium yield fluctuating between 12–18%
3–4 clogged injection lances per week
Higher calcium wire consumption per heat
Solution Implemented
Our team recommended switching to Premium Calcium Cored Wire (13mm outer diameter, 230 g/m calcium powder) with stricter quality control and uniform filling. The mill tested the product over a 4-week period on 120 heats.
Adjustments made:
Maintained same injection speed and depth
No change to existing lance equipment
Results
| Metric | Before (Standard Wire) | After (Premium Cored Wire) |
|---|---|---|
| Average calcium yield | 15% | 23% |
| Lance clogging incidents | 3–4 per week | 0–1 per week |
| Wire consumption per heat | 320 m | 210 m |
| Monthly cost savings | - | ~$8,500 USD |
Customer Feedback
"The feeding consistency of Premium Cored Wire is noticeably better. We have reduced our calcium wire usage by more than 30% while achieving cleaner steel. The technical support was also very responsive."
- Production Manager, Vietnam Steel Mill
Conclusion
The switch to Premium Cored Wire resulted in higher metallurgical efficiency, lower operating costs, and improved casting stability. The mill has since placed repeat orders and expanded usage to additional ladle furnaces.
