| description | Anode assembly for aluminium electrolysis cells comprising carbon anodes (2) with stubholes (5) and an anode hanger having stubs (4), whereas the anodes (2) are fixed to the anode hanger 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), the 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 electrolyte bath with the stub (4) and the cast iron (6). |
