“…Furnace Improvement Scenario 4: Extended Soaking Time A final improvement scenario investigated in this study was the addition of extra soaking time to the annealing cycle. Two cases were examined: two and four additional The solid CFD model temperature profiles showed that the temperatures at the three areas of coil 3 in the small coil case were a lot higher due to the faster radial heat transfer, possibly leading to more uniform coil temperatures and properties and less defects, whereas in the large coil case the outer coil temperature remained almost the same as the current case and the inner coils temperatures were much lower, possibly due to the slower conduction of heat [12,48]. S13 and S14, respectively, and the solid model results are shown in Figures 15 and 16.…”

The present study examines the performance improvement in the batch annealing process used in tinplate manufacturing by enhancing the heat transfer towards the steel coils and altering annealing cycle parameters. Presently, the heat transfer in the furnace is non-uniform, resulting in non-uniform temperature profiles and recrystallisation inside the coils, affecting the final coated steel quality. This study modelled a current furnace and four improvement proposals utilising transient computational fluid dynamics, to produce coil temperature profiles and rank the cases by the highest coil temperature uniformity achieved at the end of soaking. By increasing the soaking temperature and time, as well as the coiling tension before annealing and altering the coil size, the aim was to achieve higher and more uniform coil temperatures that could ensure successful recrystallisation with less defects, especially at the cold spot area in the middle of the coil. Then, a techno-economic analysis compared the cost-effectiveness of the scenarios based on the associated costs and the improvement in the scratching defects of the batch-annealed steel. Overall, most cases exhibited positive results regarding temperature uniformity enhancement, but increasing the coiling tension was considered the most promising option, due to the combination of a large defect reduction potential and cost savings per cycle.
