The invention relates to a self-baking carbon electrode produced in direct connection with the furnace wherein it is consumed. The electrode comprises an outer casing made from an electrical conducting material, and having inner radial, vertical ribs. Carbonaceous unbaked paste is supplied to the casing, which paste is being baked to a solid electrode by means of electric current supplied to the electrode. The inner radial, vertical ribs consist of solid carbon sheets being affixed to the inside of the casing, said carbon sheets having a ratio between radial length and thickness of above 5:1.
L'invention concerne une électrode frittée en carbone produite directement dans le four dans lequel elle est consumée. Cette électrode comprend une gaine extérieure en matériau électriquement conducteur possédant des nervures de radiales intérieures verticales. La gaine est alimentée en pâte non frittée à base de carbone, laquelle est frittée afin d'obtenir une électrode pleine, au moyen de courant électrique alimentant l'électrode. Les nervures radiales intérieures verticales sont constituées par des feuilles en carbone résistant fixées à l'intérieur de la gaine et possédant un rapport entre leur longueur radiale et leur épaisseur supérieur à 5:1.
