  • Publication number: 20240150875
    Abstract: Proposed is a method for producing a grain-oriented electrical steel sheet that comprises heating a steel material containing a certain composition and inhibitor-forming ingredients to a temperature in a range of 1300 to 1400° C.; performing hot rolling, hot-band annealing, and cold rolling on the material to obtain a cold-rolled sheet; performing decarburization annealing also serving as primary recrystallization annealing on the cold-rolled sheet; subsequently applying an annealing separator to a surface of the steel sheet; and performing finishing annealing followed by applying an insulation coating. In the method, rapid heating is conducted from 500 and 700° C. in a heating process of the decarburization annealing at a rate of 100 to 1000° C./s while gradual heating is conducted from 860 to 970° C. in a heating process of the finishing annealing at a heating rate of 0.5 to 4.0° C./hr for at least 10 hours.
