Abstract

"CéLULA DE REDUçãO ELETROLìTICA PARA A PRODUçãO DE UM METAL". Expõe-se uma célula de redução eletrolítica para a produção de um metal. A célula inclui uma pluralidade de barras coletoras (21). Cada barra coletora inclui uma primeira seção alongada (27) que contacta um catodo (15) e pelo menos uma seção extrema (29) que se estende através de uma das paredes laterais (5) da célula e está conectada eletricamente ao condutor de corrente elétrica. A célula é caracterizada pelo fato de que, para o propósito de controlar a distribuição de corrente, a primeira seção de cada barra coletora inclui um núcleo (31) de um material de condutividade elétrica relativamente alta e um alojamento externo (33) de um material que é mecanicamente e quimicamente mais resistente do que o material do núcleo, e a seção extrema de cada barra coletora é formada a partir de material de condutividade térmica relativamente baixa."ELECTROLYTIC REDUCTION CELL FOR METAL PRODUCTION". An electrolytic reduction cell is exposed for the production of a metal. The cell includes a plurality of collecting bars (21). Each collecting bar includes a first elongated section (27) that contacts a cathode (15) and at least one end section (29) that extends through one of the cell sidewalls (5) and is electrically connected to the mains conductor. . The cell is characterized by the fact that, for the purpose of controlling current distribution, the first section of each busbar includes a core (31) of a relatively high electrical conductivity material and an outer housing (33) of a material which is mechanically and chemically stronger than the core material, and the extreme section of each collecting bar is formed from relatively low thermal conductivity material.
