Abstract

"SISTEMAS CATóDICOS PAPA A PRODUçãO ELETROLìTICA DE ALUMìNIO E MéTODO PARA FABRICAçãO DOS MESMOS". A presente invenção se refere a sistemas catódicos para a fabricação eletrolítica de alumínio que são divididos, no sentido de seu eixo longitudinal, do lado da condução da corrente do catodo, em pelo menos duas partes apresentando resistência elétrica diferenciada, de tal maneira que a resistência elétrica das extremidades do coletor (2) até à parte da região periférica dos catodos voltada para o coletor comporte pelo menos 1,2 vezes a resistência elétrica apresentada das extremidades do coletor até a parte do centro do catodo voltada para o coletor, sendo que seja a massa de contato, seja o coletor são divididos em regiões (13), (14) de resistência diferenciada. Um Método para a sua fabricação e sua utilização para a fabricação eletrolítica de alumínio."CATHODIC SYSTEMS FOR ELECTROLYTIC PRODUCTION OF ALUMINUM AND METHOD FOR MANUFACTURING THE SAME". The present invention relates to cathodic systems for the electrolytic manufacture of aluminum which are divided, along their longitudinal axis, on the conduction side of the cathode current, into at least two parts having differentiated electrical resistance, such that the resistance from the ends of the collector (2) to the part of the cathode peripheral region facing the collector shall be at least 1.2 times the resistance shown from the ends of the collector to the center part of the cathode facing the collector, The contact mass, either the collector, is divided into regions (13), (14) of differentiated resistance. A method for its manufacture and its use for the electrolytic manufacture of aluminum.
