Anode assembly 1 for aluminium electrolysis cells comprising carbon anodes 2 with stubholes 5 and an anode hanger 3 having stubs 4, whereas the anodes 2 are fixed to the anode hanger 3 by cast iron 6, characterized in that the stubholes 5 are fully or partially lined with an expanded graphite lining 7. Such anode assemblies provide reduced voltage drop across the interface between the cast iron 6 and the carbon anode 7 and thus increase cell productivity significantly. Further, mechanical stresses in the stubhole 5 area are reduced. By further forming a collar 8 from the lining 7, th spilling of cast iron over the anode 2 surface is prevented and optionally a protective shot plug or a protective collar prevent direct contact of the hot electrolytebath with the stub 4 and the cast iron 6.

Ensemble d'anodes 1 destiné à des cellules d'électrolyse d'aluminium comprenant des anodes en carbone 2 ayant des orifices de goujons 5 et un dispositif de suspension d'anode 3 ayant des goujons 4, tandis que les anodes 2 sont fixées sur le dispositif de suspension d'anode 3 par de la fonte 6, caractérisé en ce que les orifices de goujons 5 sont entièrement ou 5 partiellement alignés avec un revêtement en graphite expansé 7. Ces ensembles d'anodes assurent une chute de tension réduite au sein de l'interface entre la fonte 6 et l'anode en carbone 7 et, ainsi, augmentent de manière significative la productivité des cellules. De plus, les contraintes mécaniques dans la zone de l'orifice de goujon 5 sont réduites. En formant en outre un collier 8 à partir du revêtement 7, le débordement de la fonte par-dessus la surface de l'anode 2 est empêché et, optionnellement, une fiche de protection ou un collier de protection empêche tout contact direct du bain d'électrolyte chaud avec le goujon 4 et la fonte 6.
