Abstract

L'invention concerne un procédé perfectionné de fabrication de feuilles d'acier au silicium à grains orientés ne comportant sensiblement pas de film vitreux, dans lequel une feuille d'acier au silicium laminée à froid ayant l'épaisseur finale est soumise à un recuit de décarburation pour former une sous-couche d'oxydes sous la surface de la feuille d'acier. On applique sur la sous-couche un séparateur de recuit consistant principalement en A12O3 et on soumet ensuite la feuille d'acier à un recuit final. Selon l'invention, on utilise un séparateur de recuit consistant en 5-30 % d'un silicate hydraté en fines particules, 0,2-20 % d'un composé de strontium ou de baryum, calculés en strontium ou en baryum, 2-30 % de CaO de Ca(OH)2 et le reste de Al2 O3 .
