| Abstract Scope |
Producing Anodes with the highest uniformity and consistent properties is essential to improve the energy efficiency and productivity of the Hall-Héroult process. One of the production parameters which may affect the anode quality is the position of the anodes in the baking furnace on their final properties. During the baking process, the anodes are stacked in the pits of the furnace and baked according to predefined temperature profiles. Stacking the anodes may generate mechanical stress on the lower anodes. This additional stress state could affect the rearrangement of the anode coke particles, leading to internal structure anisotropy. To investigate the effect of this parameter, we measured the electrical resistivity and density of the anodes baked at different positions in the furnace. The results show a statistically meaningful variation of the electrical resistivity as a function of anode position in the furnace. |
