METHOD FOR PRODUCING A GRAIN-ORIENTED ELECTRICAL STEEL SHEET ABSTRACT OF THE DISCLOSURE In the production of a grain-oriented electrical steel sheet, instead of conventional inhibitors a novel (Al, Si)N inhibitor is utilized. This inhibitor is formed by obtaining an incomplete solution of Al and N and then nitriding the decarburization annealed steel sheet prior to initiation of a secondary recrystalliza- tion. The fine inhibitor can be formed in a large amount, thereby enhancing the magnetic flux density.
