Abstract

SUIVANT CE PROCEDE, ON FABRIQUE UN ACIER FONDU DEGAZE SOUS VIDE CONTENANT MOINS DE 0,025 EN POIDS DE CARBONE, ENTRE 0,1 ET 1,0 DE MANGANESE, ENTRE 0,01 ET 0,15 DE PHOSPHORE, PAS PLUS DE 0,02 DE SOUFRE, PAS PLUS DE 0,007 D'AZOTE, AVEC DU TITANE DANS LA PLAGE DE 0,5 A 0,25, LE RESTE ETANT DU FER ET DES IMPURETES. ON EN LAMINE UNE BRAME A CHAUD AVEC UNE TEMPERATURE DE FIN DE LAMINAGE COMPRISE DANS LA PLAGE DE 900 A 950C, ET ON ENROULE A UNE TEMPERATURE QUI N'EST PAS INFERIEURE A 700C LE FEUILLARD LAMINE A CHAUD OBTENU.
