Abstract
Provided is a method for refining magnetic domains of grain-oriented electrical steel plates including: a steel plate supporting roll position adjusting step of controlling a vertical direction position of the steel plate while supporting the steel plate; a laser radiating step of melting the steel plate by radiating a laser beam to form grooves on the surface of the steel plate; and a setting and maintaining step of setting and maintaining an internal operation environment of a laser room in which the laser radiation is performed, so as to increase magnetic domain refinement efficiency and improve workability by optimizing equipment and processes, thereby increasing the processing capacity.
