Title (EN) ELECTROLYSIS CELL, IN PARTICULAR FOR THE PRODUCTION OF ALUMINUM
(FR) CELLULE D'ÉLECTROLYSE, EN PARTICULIER POUR LA PRODUCTION D'ALUMINIUM
(DE) ELECTROLYSIS CELL, IN PARTICULAR FOR THE PRODUCTION OF ALUMINUM
Abstract:
(EN) The present invention relates to an electrolysis cell, particularly for the production of aluminum, which comprises a cathode, a layer of liquid aluminum arranged on the upper side of the cathode, a melt layer thereon and an anode on the top of the melt layer, wherein the cathode is composed of at least two cathode blocks, wherein at least one of the at least two cathode blocks differs from at least one of the other cathode block(s) with regard to at least one of the average compressive strength, the average thermal conductivity, the average specific electrical resistivity and the apparent density.
(FR) La présente invention concerne une cellule d'électrolyse, en particulier pour la production d'aluminium, qui comprend une cathode, une couche d'aluminium liquide agencée sur la face supérieure de la cathode et sur laquelle se situe une couche de métal en fusion, ainsi qu'une anode sur la partie supérieure de la couche de métal en fusion, la cathode étant composée d'au moins deux blocs cathodiques, au moins l'un des au moins deux blocs cathodiques différant d'au moins un bloc parmi le ou les autres blocs cathodiques en ce qui concerne la résistance à la compression moyenne, et/ou la conductivité thermique moyenne, et/ou la résistivité électrique spécifique moyenne, et/ou la densité apparente.
