  • the anodes are more particularly of the prebaked anode type with prebaked carbon anode blocks, that is to say baked before introduction into the electrolysis tank.
  • the anode blocks are often suspended from an anode support to form with said blocks what is often called the anode assembly.
  • the anode assembly is generally movable relative to the box and can be moved vertically using displacement means in order to compensate for the consumption of the anode blocks during electrolysis and the variations in the level of aluminum accumulating on the cathode.
