Abstract
Until recently, analyses and control strategies of the remelting processes assumed that in the high temperature region the process current is completely contained in the path between the electrode and the ingot. It is now generally recognised that there is also a second path, electrode to mould (‘mould current’), which plays a significant role in both the process heat balance and process parameters, hence influencing the ingot structure. This report critically reviews the published experimental evidence and process analyses relating to the effect. In both the main processes, electroslag remelting and vacuum arc remelting, the mould current plays an important part in establishing ingot structure but in the present process operations it is neither measured nor controlled. It is postulated that further work directed towards control of the mould current is necessary for optimising reproducible ingot quality. It is further concluded that valid computational analyses of the processes must allow for the component of mould current.

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
