Abstract

On obtient une tole d'acier électrique à grains orientés d'une épaisseur de 0,10 à 0,23 mm par un procédé caractérisé par une décarburation réalisée après le laminage à chaud et avant le laminage à froid final, après quoi on réalise le recuit de décarburation et le recuit de finissage connus, la composition de l'acier étant ajustée pour induire la recristallisation secondaire par un inhibiteur d'AIN. Les toles d'acier trouvent e.a. une application dans la production de transformateurs.
