Hypothesis
The structure of the ladle bottom with ceramic dams influences the mixing process and time required for chemical homogenization.
Conclusion
Using a set of ceramic dams in the ladle bottom can significantly reduce the mixing time of liquid metal by up to 50%.
Supporting Evidence
- Using a semi-circle dam reduced mixing time by 42%.
- Using a set of dams achieved a 50% reduction in mixing time.
- Deeper immersion of the lance also contributed to reduced mixing times.
Takeaway
This study shows that adding special barriers in a ladle can help mix metal faster, making it more uniform without needing more gas.
Methodology
The study used both physical water models and numerical simulations to assess mixing times under various conditions.
Limitations
The study primarily focused on specific configurations and may not account for all industrial variations.
