| description | A method and a device for refining a magnetic domain of a grain-oriented electrical steel sheet are provided. According to the present invention, a method for refining a magnetic domain of a grain-oriented electrical steel sheet stably performs permanent magnetic domain refinement treatment when the electrical steel sheet is processed at a high speed of 2m/s or higher, and comprises: a snaking control step of allowing the steel sheet to move straight without being biased to the left or right along the center of a production line; a tension control step of providing tension to the steel sheet such that the steel sheet is maintained in a flatly spread state; a steel sheet support roll position adjusting step of controlling a vertical direction position of the designated steel sheet while supporting the steel sheet; and a laser emitting step of emitting laser beams so as to melt the steel sheet and form a groove on the surface of the steel sheet.
