Abstract
An industrial-sized vertical low-head direct chill slab casting process for the aluminium alloy AA-6061 is modelled by taking into account the 3-D turbulent melt flow and heat transfer in the liquid sump and by giving proper consideration of the mushy region solidification aspect of the process. Computed results for the steady-state phase of the casting process are presented for four casting speeds, varying from 60 to 180 mm min−1, for three metal–mould effective heat transfer boundary conditions, varying from 1.0 to 4.0 kW m−2 K−1 and for three inlet melt superheats of 16, 32 and 64 °C. A step-wise change of the cooling water temperature in the mould, impingement and free streaming regions are considered to reflect the actual operations. Detailed results in the form of velocity and temperature fields, solidification shell and mushy region thickness, sump depth and temperature profiles at four critical locations along the caster are provided and discussed.

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
