Abstract

MODIFICACIONES INTRODUCIDAS EN UNA CELDA DE REDUCCION ELECTROLITICA PARA LA PRODUCCION DE METALES POR ELECTROLISIS DE UN ELECTROLITO FUNDIDO MENOS DENSO QUE EL METAL. CONSISTE EN PREPARAR UNA CUBA CON UN SUELO DE CARBON CATODICO QUE TIENE BARRAS COLECTORAS DE ACERO EMPOTRADAS PARA EXTRAER LA CORRIENTE CATODICA. UNOS MIEMBROS DE BARRERA ALARGADOS, NO CONDUCTORES DE LA CORRIENTE ELECTRICA, SE EXTIENDEN HACIA ARRIBA DESDE EL SUELO DE LA CUBA HASTA UNA ALTURA PROXIMA AL NIVEL DE FUNCIONAMIENTO MAXIMO NORMAL DE METAL FUNDIDO. ESTOS MIEMBROS DE BARRERA SON DE MATERIAL RESISTENTE AL METAL FUNDIDO Y ESTAN DISPUESTOS TRANSVERSALMENTE AL FLUJO DE CORRIENTES HORIZONTALES EN EL METAL PRODUCTO EN EL SUELO CATODICO DE LA CUBA. ESTAS CELDAS TIENEN APLICACIONES PARA LA OBTENCION ELECTROLITICA DE ALUMINIO.
