Abstract

"PROCESSO E APARELHO PARA O POSICIONAMENTO DE ANÈDOS DE SUBSTITUIçãO EM CéLULAS ELETROLìTICAS". Um anódo gasto é substituído por um ânodo novo em uma célula de eletrólise que tem uma barra coletora de anódo e uma haste de anódo contatando a barra coletora. Uma distância desejada (D4) a partir da barra coletora até um ponto de referência em ou adjacente a uma haste de anódo para o ânodo novo é calculada, o anódo gasto é substituído pelo ânodo novo, de modo que o ponto de referência na nova haste de anódo seja espaçado da barra coletora por uma distância real (D5), e a distância real (D5) é medida pelo menos uma vez por meio de um sistema de visão. A distância real (D5) é preferencialmente ajustada usando-se um laço de controle de feedback em um computador, de modo que D5 se aproxime da distância desejada (D4).
