Grain Oriented Electrical Steel Sheet And Method For Refining Magnetic Domain Of Same
Abstract: A grain-oriented electrical steel sheet according to one embodiment of the present invention comprises: linear grooves formed on one surface or both surfaces of the electrical steel sheet in a direction crossing the rolling direction; and linear thermal shock parts formed on the one surface or both surfaces of the electrical steel sheet in the direction crossing the rolling direction. The grooves are formed along the rolling direction, and the distance (D2) between the grooves and the thermal shock parts is 0.2 to 0.5 times the distance (D1) between the respective grooves, and the distance (D3) between the respective thermal shock parts is 0.2 to 3.0 times the distance (D1) between the respective grooves.
