Abstract Scope |
Electrolysis cells can be preheated electrically or thermally, but aluminium industry prefers electrical preheating with Lying-Bed due to economical aspects. Preheating phase has a significant impact on the early cell operation and cell life since it goes through significant thermal, electrical and mechanical changes during this phase. Hence, a successful preheating is crucial for the smelter’s productivity. Thus, it is essential to determine the conditions/parameters for a good cell preheating. In this work, the preheating of an electrolysis cell for various Lying-Bed patterns are simulated using a strongly coupled, thermo-electrical ¼-cell model developed in ANSYS™. The thermal and electrical properties of the coke/graphite Lying Bed are estimated using calibration procedure with in situ measurements and the results are compared in order to determine the better possible Lying-Bed pattern in terms of anodic current distribution, cathode surface temperature distribution, baking level of ramming paste. |
