Abstract

L'invention se rapporte à l'industrie sidérurgique et peut s'utiliser dans la fabrication d'aciers électrotechniques texturés présentant une perméabilité élevée de flux magnétique. Le procédé consiste à effectuer la fusion du métal, la distribution en continu du métal en fusion, le chauffage de l'ébauche, le laminage à chaud grossier et de finition, deux laminages à froid séparés par un recuit de recristallisation et de décarburation, un recuit haute température et de redressement, le chauffage de l'ébauche s'effectuant jusqu'à des températures assurant la formation d'une structure de ferrite du métal, et le laminage à chaud de finition s'effectuant dans une gamme de températures de recristallisation de phases α->η->α de manière à ce qu'au stade final du laminage à chaud de finition la partie en masse d'austhénite dans l'acier soit inférieure ou égale à 3 %. En outre, avant la distribution en continu du métal en fusion il comprend, en % en masse, 0,020-0,028 de carbone, 3,05-3,15 de silicium, 0,1 0,3 de manganèse, 0,4-0,6 de cuivre, 0,011-0,025 d'aluminium soluble dans un acide, 0,008- 0,016 d'azote, le reste étant constitué de fer. Avant la distribution, la teneur du métal en fusion en carbone est ajustée en fonction de la teneur en silicium; lorsque la teneur en silicium augmente de 0,1 % en masse en dessus de 3,15 % en masse, on augmente la teneur en carbone de 0,003 % en masse en dessus de 0,028 % en masse.
