Abstract Scope |
The aluminium smelting industry always seeks ways to increase efficiency and reduce costs. However, the trend towards longer anodes has increased the risk of breakages due to their proximity to crust breakers and feeders. A portion of the carbon area on the top corner and side of the anodes remains unused during electrolysis and is lost due to "Airburn" and "Carboxy" attack. This area is prone to breakage because of its proximity to breakers in the electrolysis cell. To solve this problem, chamfered sides on anodes have been implemented. Chamfering involves beveling the anode edges and has been shown to remove unused carbon areas, offering several potential advantages. Our analysis shows that this design modification can significantly lower raw material, transportation costs, and carbon consumption. This paper comprehensively reviews the chamfered anode design and highlights its economic and environmental benefits while maintaining the anodes' mechanical integrity within aluminium reduction cells. |
