  • Method and apparatus for disintegration of solidified bath material on the residues of prebaked anodes from aluminium electrolysis cells
    Patent number: 4469281
    Abstract: The disintegration of solidified bath material on the residues of prebaked anodes is achieved by partially removing the bath material from the anode surface by core drilling which simultaneously initiates disintegration of the remaining bath layer. One or more core drills are moved parallel to the anode surface between steel nipples of the anode rod for disintegration of the bath layers.

  • Means for cooling of self-baking anodes in aluminum electrolysis cells
    Patent number: 4073714
    Abstract: A cooling device for self-baking anodes in electrolytic cells for the production of aluminum includes plural cooling rods extending through openings in a supporting bar and supported thereby in a row covering a band-shaped zone along the center line of the cell anode. Each cooling rod is partly submerged in the anode mix of the cell and has a collar which determines the extent of such submergence. Each cooling rod is an aluminum extrusion having longitudinal ribs radiating from a center section.
