Abstract

resumo ?coletor de corrente de catodo para uma célula de hall- héroult?. a invenção refere-se a uma célula eletrolítica (1) para a produção de alumínio (2) incluindo modificações de estrutura de barras coletoras (13,14,15,16) sob o catodo (4), ou seja, uma barra coletora de cobre mantida em um perfil em forma de u ou diretamente encaixada no catodo. isto conduz a uma distribuição de corrente optimizada no metal de alumínio líquido (2) e/ou no interior do catodo de carbono permitindo o funcionamento da célula a uma menor tensão. a menor tensão resulta de uma distância menor de anodo para o catodo (acd) e/ou de uma menor queda de tensão no interior do catodo de carbono a partir do metal líquido até a extremidade da barra coletora.
