Beschreibung
Zusammenfassung:	To optimize equipment and processes to enhance magnetic domain refinement efficiency and to enhance workability to improve processing capability, a method of refining a magnetic domain of a grain-oriented electrical steel plate includes zigzag controlling for transferring the steel plate without being inclined in right and left directions along a production line center, steel plate support roll position adjusting for controlling a position of the steel plate in up and down directions while supporting the steel plate, laser beam irradiating for irradiating a laser beam to a surface of the steel plate to melt the steel plate to form a groove in the surface of the steel plate, and removing for absorbing and removing radiant heat due to reflection of the laser beam irradiated to the surface of the steel plate during the laser beam irradiating.
