PROBLEM TO BE SOLVED: To provide a method for producing a grain oriented magnetic steel sheet attaining low iron loss without the peeling of a forsterite film from ferrite.SOLUTION: Provided is a method for producing a grain oriented magnetic steel sheet where, after finish annealing, in any step before magnetic domain fragmentation treatment, in any position of a forsterite film, Ti strength is measured by fluorescent X-ray analysis, and, thereafter, in the process of magnetic domain fragmentation treatment, based on the measured Ti strength, the heat strain amount to be applied is adjusted.SELECTED DRAWING: None |
