Abstract

L'INVENTION CONCERNE UN PROCEDE DE PRODUCTION DE FER AU SILICIUM ORIENTE EN BRAMES COULEES EN BARRES. LE PROCEDE COMPORTE LES ETAPES CONSISTANT A FONDRE ET A AFFINER LA CHARGE FERREUSE POUR OBTENIR UNE MASSE FONDUE QUI CONTIENT DES PROPORTIONS, COMPRISES DANS DES GAMMES RIGOUREUSES, DE CARBONE, DE MANGANESE, DE SOUFRE ETOU DE SELENIUM, ET DES TAUX TENUS RIGOUREUSEMENT BAS D'AZOTE, D'ALUMINIUM ET DE TITANE, A COULER EN EPAISSEUR DE BRAME D'ENVIRON 125 A ENVIRON 225MM, A EFFECTUER UN REVENU OU UN RECHAUFFAGE DES BRAMES DE 1330C ENVIRON A 1400C, A LAMINER A CHAUD, A RECUIRE DE 925C ENVIRON A 1050C ENVIRON, A LAMINER A FROID EN DEUX ETAPES AVEC UN RECUIT INTERMEDIAIRE JUSQU'A L'EPAISSEUR FINALE, A DECARBURER ET A SOUMETTRE LA MATIERE A UN RECUIT FINAL EN ATMOSPHERE REDUCTRICE CONTENANT DE L'HYDROGENE POUR EFFECTUER UNE RECRISTALLISATION SECONDAIRE. LES PRODUITS OBTENUS PRESENTENT UNE PERMEABILITE UNIFORMEMENT ELEVEE ET UNE FAIBLE PERTE DU NOYAU. LES PROPRIETES MAGNETIQUES SONT AMELIOREES.
