Method For Refining Magnetic Domains Of Grain Oriented Electrical Steel Plates And Apparatus Therefor
Abstract: Provided is a method for refining the magnetic domains of grain-oriented electrical steel plates so as to optimize equipment and processes and thereby increase magnetic domain refinement efficiency improve workability and increase processing capacity the method comprising: a steel plate supporting roll position controlling step for controlling the vertical position of steel plates while supporting the steel plates moving along a production line; a laser radiation step for radiating a laser beam to the surface of the steel plates so as to melt the steel plates and thereby form grooves in the surface of the steel plates; and a removal step for removing spatters fallen and remaining on the surface of the steel plates after the laser radiation.
