Abstract

L'invention concerne un procédé pour préparer de l'acier électromagnétique au silicium. On prépare une masse fondue d'acier au silicium contenant jusqu'à 0,07 % de carbone, 0,01 à 0,25 % de manganèse, 0,01 à 0,09 % de soufre et/ou de sélénium, 2,5 à 4,0 % de silicium, jusqu'à 1,0 % de cuivre, moins de 0,009 % d'aluminium et moins de 0,0006 % de bore, on coule l'acier, on lamine l'acier à chaud, on lamine l'acier à froid, on normalise l'acier dans une atmosphère contenant de l'hydrogène présentant un rapport PH 2 O/PH2 de 0,015 à 0,3, on applique un revêtement d'oxyde réfractaire contenant un oxyde moins stable que SiO2 aux températures atteignant 1 177 degrés C et on soumet l'acier à un recuit de texturation final. L'invention s'applique en particulier à la préparation d'acier électromagnétique au silicium ayant une orientation cube sur arête.
