GRAIN-ORIENTED ELECTRICAL STEEL SHEET AND PRODUCING METHOD THEREFOR

A producing method of a grain-oriented electrical steel sheet includes forming a preferentially-deformable portion at an end region of a steel sheet so as to be parallel with the rolling direction of the steel sheet; coiling the steel sheet; and performing a final annealing to the steel sheet after...

Summary:A producing method of a grain-oriented electrical steel sheet includes forming a preferentially-deformable portion at an end region of a steel sheet so as to be parallel with the rolling direction of the steel sheet; coiling the steel sheet; and performing a final annealing to the steel sheet after disposing the steel sheet in a manner such that the end region becomes the lower side of the steel sheet.
