Superstructure for a very high power electrolysis cell for the production of aluminum

摘要

Superstructure for a very high power electrolysis cell for the production of aluminum using the Hall-Héroult process. The cell being formed of a heat-insulated metal casing of elongated parallelepipedic shape. The said superstructure comprising at least one rigid beam disposed along the long length of the casing, resting on supports, and supporting in particular the anodic frame structure to which are connected on the one hand the current risers coming from the preceding cell in the series and on the other hand the anode rods, characterized in that each rigid beam rests only upon supports placed between its ends, termed intermediate gantries. In that each anodic frame structure associated with each rigid beam includes electrical and mechanical connection or connectors to the anode completely fixed to the anodic frame structure and ensuring the contact and the clamping of each anode rod against it following lateral engagement and positioning of each rod in the corresponding connector.
