Abstract

"BLOCOS DE CATODO PARA CéLULA DE ELETRóLISE DE ALUMìNIO COM MECANISMO DE DETECçãO DE DESGASTE". A presente invenção refere-se a blocos de catodo para células de eletrólise de alumínio fornecendo uma funcionalidade de detecção para indicar a extensão do desgaste de catodo nas células de eletrólise de alumínio sem interromper a operação da célula pela introdução de materiais residuais no bloco de catodo que escoam pela penetração do alumínio e podem ser detectados pelas técnicas analíticas."CATHODE BLOCKS FOR ALUMINUM ELECTROLYSIS CELL WITH WEAR DETECTION MECHANISM". The present invention relates to cathode blocks for aluminum electrolysis cells providing detection functionality to indicate the extent of cathode wear on aluminum electrolysis cells without disrupting cell operation by introducing waste materials into the cathode block. that flow through aluminum penetration and can be detected by analytical techniques.
