Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE CUERPOS CARBONOSOS, EN PARTICULAR DE ELECTRODOS, CON FORMA PARALELEPIPEDICA, CUBICA O CILINDRICA PARA ELECTROLISIS DEL ALUMINIO, MEDIANTE CALCINACION DE CUERPOS CONFORMADOS CRUDOS, QUE CONTIENEN SUSTANCIAS PIROLIZABLES, EN UN HORNO DE TUNEL. CARACTERIZADO PORQUE HASTA EL ALCANCE DEL REBLANDECIMIENTO COMPLETO DEL LIGANTE EN EL INTERIOR DE LOS CUERPOS CARBONOSOS, UN PESO SUBDIVIDIDO HOMOGENEAMENTE EN FUNCION DEL LIGANTE ACTUA SOBRE LA SUPERFICIE O SOBRE LAS SUPERFICIES DE COBERTURA DE LOS CUERPOS CARBONOSOS; Y PORQUE LOS CUERPOS CARBONOSOS SE CALIENTAN HASTA APROXIMADAMENTE 200 GRADOS, CON UN GRADIANTE TERMICO MAXIMO DE 10 GRADOS POR HORA
