Abstract

La présente invention permet la fabrication stable de tôles d'acier au silicium à grains orientés qui possèdent d'excellentes propriétés magnétiques avec une forte productivité en combinant efficacement le traitement par vieillissement au laminage en tandem, au moyen de laquelle le laminage à froid est réalisé jusqu'à ce qu'une épaisseur finale ait été atteinte. Lors de l'étape finale de laminage à froid de la fabrication des tôles d'acier au silicium à grains orientés, le laminage en tandem est d'abord réalisé, puis le traitement thermique continu est effectué, de préférence, en appliquant en même temps une tension.
