Abstract

ELEMENTO CATóDICO PARA EQUIPAMENTO DE UMA CéLULA DE ELETRóLISE DESTINADA à PRODUçãO DE ALUMìNIO. A presente invenção tem por objeto um elemento catódico, para o equipamento de uma cuba de célula de eletrólise, destinada á produção de alumínio, comportando um bloco catódico (5) em material carbonado que tem pelo menos uma ranhura longitudinal sobre uma de suas faces laterais e uma barra de ligação (6) em aço, que é alojada nessa ranhura, por interposição de um material de chumbamento condutor, entre a barra e o bloco e que contém pelo menos um enxerto metálico, cuja condutividade elétrica é superior àquela desse aço. De acordo com a invenção, o enxerto é disposto longitudinalmente no interior da barra e se situa, pelo menos em parte, nesse trecho (19) da barra de ligação que é destinada a se situar no exterior da cuba e a barra de ligação (6) não é chumbada no bloco catódico em uma zona dita de "não chumbamento" (17) de superfície determinada S situada na extremidade da ranhura na cabeça de bloco. A presença de um enxerto, de acordo com a invenção, permite obter simultaneamente uma redução muito forte da queda de tensão catódica global e da densidade de corrente na cabeça de bloco.
