Abstract
In gas stirred steelmaking ladles, entrainment of liquid slag into liquid steel and vice versa takes place. Qualitatively, slag entrainment is known to increase slag-metal interfacial reaction rates. However, it is unknown how the entrainment is quantitatively affected by gas stirring rate and the properties of the slag and metal. In this paper the modelling of slag entrainment is resolved into several sub-models to determine the interfacial reaction rates between slag and metal for the droplets and other interfaces. The model predictions are in line with literature values for refining rates and also rationalize the effects of ladle size and number of gas injection plugs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
