Abstract
A mathematical model has been developed to simulate the phenomenon of heat transfer occurring during a novel magnesium reduction process - the vertical retort technology. The model was based on the control-volume finite difference approach. The simulations were run to determine the effect of various parameters, such as the diameter and thickness of the compound, and slot angle, on the magnesium reduction cycle time. The model predicted the temperature distributions, the heating curves, and the total process time. The predictions were used to optimize the magnesium reduction process including the dimensions of the retort, shapes of charged materials, and reduction cycle time. The computed results show that the utilization of the optimized process parameters leads to a decrease in reduction time and energy consumption, and an increase in production capacities and recovery rates. Consequently, the magnesium thermal reduction process is significantly improved in the vertical retort. The model has been verified in a demo-plant operation with an annual production capacity of 1200 ton magnesium.

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
