Cell Preheat/Start-up and Early Operation

  • Ketil Å. Rye

Abstract

The most common methods for preheating industrial aluminum pots are reviewed and advantages and disadvantages of each method are presented. Also, the present industrial trend of reducing pot turnaround times is commented and measurements of deep-lining temperatures at start-up are related to the pot behavior in early operation. In general it is seen that shorter preheating times is unfavorable for pot stability in early operation and this effect may limit the potential for further pot turnaround time reductions or lead to operational problems and/or reduced potlife.
