DEVICE FOR PRODUCING GRAIN-ORIENTED MAGNETIC STEEL SHEET AND METHOD FOR PRODUCING GRAIN-ORIENTED MAGNETIC STEEL SHEET

摘要

This device (10) for producing a grain-oriented magnetic steel sheet that produces a grain-oriented magnetic steel sheet that has been subjected to magnetic domain control by means of laser beam irradiation has: laser beam radiating devices (20) of which a plurality have been provided in the direction of conveyance of a steel sheet (31); and a conveyance direction motion mechanism (15) that moves the laser beam radiating devices (20) in the direction of conveyance of the steel sheet (31).
