Abstract

LA PRESENTE INVENTION EST RELATIVE A UNE AMELIORATION DANS LE RECUIT DE PRECIPITATION D'UNE TOLE OU D'UN FEUILLARD EN ACIER LAMINE A CHAUD QUI EST REALISEE IMMEDIATEMENT AVANT LE LAMINAGE A FROID AU COURS DE LA FABRICATION DE TOLES OU DE FEUILLARDS EN ACIER ELECTROMAGNETIQUE A GRAIN ORIENTE. HABITUELLEMENT, LE RECUIT DE PRECIPITATION EST REALISE PAR LE CHAUFFAGE D'UN FEUILLARD EN ACIER A UNE TEMPERATURE COMPRISE ENTRE 750 ET 1200C SUIVI D'UNE TREMPE DE CELUI-CI. LA PRESENTE INVENTION PROPOSE DE CONTROLER LE TAUX DE REFROIDSSSEMENT DURANT LE REFROIDISSEMENT PRIMAIRE, C'EST-A-DIRE D'UNE TEMPERATURE MAINTENUE T COMPRISE ENTRE 1080 ET 1200C A UNE TEMPERATURE INTERMEDIAIRE T COMPRISE ENTRE 900 ET 980C, ET DE CONTROLER LE TEMPS D'ARRET DURANT LE REFROIDISSEMENT PRIMAIRE POUR OBTENIR DES PROPRIETES MAGNETIQUES EXCELLENTES MALGRE LES INEVITABLES VARIATION DE LA TENEUR EN ALUMINIUM ET EN SILICIUM. LA PRESENTE INVENTION PROPOSE EGALEMENT DE CONTROLER LE TAUX D'ELEVATION DE LA TEMPERATURE ENTRE 800C ET LA TEMPERATURE MAINTENUE POUR OBTENIR DES PARTICULES DE A1N PRESENTANT UNE TAILLE OPTIMALE.
