Abstract

CATODOS PARA CELDAS DE ELECTROLISIS EN FUSION PARA LA OBTENCION DE ALUMINIO. CONSTAN DE ELEMENTOS INTERCAMBIABLES CONSTITUIDOS POR MATERIALES DIFERENTES UNIDOS RIGIDAMENTE Y RESISTENTES A LOS CHOQUES TERMICOS; SU PARTE SUPERIOR SE SUMERGE DESDE EL ELECTROLITO LIQUIDO EN EL ALUMINIO SEPARADO; LA PARTE INFERIOR ESTA COLOCADA DENTRO DEL ALUMINIO LIQUIDO. LA PARTE SUPERIOR DE LOS ELEMENTOS DE COMPONE DE PLACAS COLOCADAS VERTICALMENTE, LAS QUE CON LA SUPERFICIE HORIZONTAL SE EXTIENDEN CON PREFERENCIA POR TODA LA ZONA DE LA SUPERFICIE ACTIVA DEL CORRESPONDIENTE ANODO.
