Slag carry-over in ladle refining operations is most likely one of the last unknowns in metals processing. No-one can for certain tell that the carry over amount is under control and does not influence on processing and product quality.
We know for sure that the variation in sub-sequent processing operations due to uncontrolled slag carry-over is larger thn you would expect with very unfavorable consequences:
- Processing instability increases and targets are missed.
- Product quality suffer.
This paper elaborates on the influence on processing, production, and product quality by slag carry-over in ladle refining operations. You will be surprised that something unknown and usually poorly controlled influences so strongly on your daily operations.
