Resumo
At the end of a ladle draining operation a structure called drain sink forms at the top surface of the liquid steel
allowing slag carry over from the ladle to the tundish and causing metallic losses. On this study, the effect of different
well block configuration on the critical height for drain sink formation (HC) was investigated using numerical and physical
modeling. The modified well block configuration showed lower HC in most of the cases when compared with the standard
design. It could represent almost 50% of metallic lost savings during the continuous casting process. Air injection was
also investigated and increased significantly the HC value. The numerical model showed good agreement with the physical
model and was used to help undertanding this behavior.
