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.
