Abstract

La présente invention ne fait pas qu'améliorer la formation d'une structure cristalline fine et, de ce fait, les propriétés magnétiques ainsi que les propriétés de surface tout en utilisant au maximum les avantages d'un laminoir à bandes à chaud en effectuant un laminage d'ébauche selon les étapes pour la production de feuilles d'acier au silicium à grains orientés, particulièrement l'étape du laminage à bandes à température élevée et une importante réduction, mais elle permet aussi de réaliser de manière stable l'amélioration des propriétés magnétiques avec une fiabilité élevée en contrôlant avec précision la précipitation de l'inhibiteur au stade du laminage de finissage à l'étape du laminage à chaud.
