Managing Potlife through Statistical Analysis
A significant portion of ongoing costs in aluminium smelters comprises of electrolysis cell reconstruction. The cells, also referred as pots, undergo different wear mechanisms and failure modes determining their finite lifespan. Smelters have to carefully manage all aspects determining potlife to maximize it while minimizing reconstruction costs. Pot design, materials and supplier selection, construction quality and electrolysis operations all affect potlife.
