Abstract

L'INVENTION CONCERNE UN PROCEDE POUR LA PRODUCTION D'ALUMINIUM EN DEUX ETAPES: (CF DESSIN DANS BOPI) ET (CF DESSIN DANS BOPI) LA REACTION 2 A LIEU DANS UNE CHAMBRE D'ADDITION DE MATIERES ET LA REACTION 3 DANS UNE CHAMBRE A TEMPERATURE ELEVEE. ON FAIT CIRCULER DE LA SCORIE ENTRE LES CHAMBRES DANS DES CANALISATIONS ET ON PROVOQUE LA CIRCULATION PAR DU GAZ PROVENANT D'UNE SOURCE EXTERIEURE. LE CHAUFFAGE DES CHAMBRES PEUT ETRE EFFECTUE PAR CHAUFFAGE PAR RESISTANCE ELECTRIQUE ENTRE DES ELECTRODES SITUEES DANS LES CHAMBRES ET LE GAZ PEUT ETRE INTRODUIT PAR PASSAGE A TRAVERS UNE OU PLUSIERS ELECTRODES CREUSES. APPLICATION A LA PROTECTION D'ALUMINIUM.
