Abstract
L'INVENTION CONCERNE UN PROCEDE DE FABRICATION OU LA BANDE D'ACIER EST REVETUE PAR IMMERSION DANS UN BAIN METALLIQUE APPROPRIE, MAINTENU A UNE TEMPERATURE SUPERIEURE A 500C. LE PROCEDE EST CARACTERISE EN CE QU'A LA SORTIE DU BAIN, LA BANDE EST SOUMISE A UN PREMIER REFROIDISSEMENT JUSQU'A LA TEMPERATURE A LAQUELLE LA COUCHE METALLIQUE DONT ELLE EST RECOUVERTE SE SOIT SOLIDIFIEE, PUIS A UN REFROIDISSEMENT BRUTAL ET RAPIDE, MAIS NE COMPROMETTANT PAS LA PLANEITE DE LA BANDE, JUSQU'A UNE TEMPERATURE INFERIEURE A 475C. APPLICATION DANS LE CAS OU LA BANDE EST REVETUE, PAR IMMERSION, DANS UN BAIN D'UN MELANGE DE ZINC ET D'ALUMINIUM, NOTAMMENT.
