Abstract
L'INVENTION CONCERNE LA METALLURGIE. LE PROCEDE FAISANT L'OBJET DE L'INVENTION EST DU TYPE CONSISTANT A CREER UN BAIN DE LAITIER DANS UNE LINGOTIERE REFROIDIE 2, A LE CHAUFFER A L'AIDE D'ELECTRODES 5 ET A COULER LE METAL LIQUIDE PAR PORTIONS A TRAVERS LA COUCHE DE LAITIER LIQUIDE 7, LA COULEE DE CHAQUE PORTION ETANT EFFECTUEE APRES SOLIDIFICATION DE PLUS DE 50 DE LA PORTION PRECEDENTE, ET EST CARACTERISE EN CE QU'ON ARRETE LA COULEE DE LA PREMIERE PORTION 9 DE METAL LIQUIDE DANS LE BAIN DE LAITIER QUAND LA MASSE DU METAL DANS LA LINGOTIERE ATTEINT 30 A 50 DE LA MASSE TOTALE DU LINGOT, ET QU'ON EFFECTUE LA COULEE DE CHACUNE DES PORTIONS SUIVANTES JUSQU'A CE QUE SA MASSE DANS LA LINGOTIERE ATTEIGNE 10 A 50 DE LA MASSE DE LA PREMIERE PORTION. L'INVENTION S'APPLIQUE NOTAMMENT A L'ELABORATION DE LINGOTS DE GRANDES DIMENSIONS DESTINES A ETRE EMPLOYES COMME EBAUCHES POUR LA FABRICATION DES ROTORS DE GENERATEURS ET D'AUTRES PIECES DE GRAND ENCOMBREMENT.
