Title (EN) GRAIN-ORIENTED ELECTRICAL STEEL SHEET AND METHOD FOR MANUFACTURING SAME
(FR) TÔLE D'ACIER ÉLECTRIQUE À GRAINS ORIENTÉS ET SON PROCÉDÉ DE FABRICATION
(KO) 방향성 전기강판 및 그의 제조 방법
Abstract:
(EN) A grain-oriented electrical steel sheet according to an embodiment of the present invention comprises: a forsterite layer formed on the surface of an electrical steel sheet; a groove which is formed on the forsterite layer in a direction perpendicular to a rolling direction; and a forsterite calcination layer which is formed in the direction of both ends of the electrical steel sheet on the basis of an upper end of the groove and has a width of 1.1 to 1.3 times the width of the groove.
(FR) Selon un mode de réalisation, la présente invention concerne une tôle d'acier électrique à grains orientés, comprenant : une couche de forstérite formée sur la surface d'une tôle d'acier électrique ; une rainure qui est formée sur la couche de forstérite dans un sens perpendiculaire à un sens de laminage ; et une couche de calcination de forstérite qui est formée dans le sens des deux extrémités de la tôle d'acier électrique sur la base d'une extrémité supérieure de la rainure et présentant une largeur de 1,1 à 1,3 fois supérieure à la largeur de la rainure.
(KO) 본 발명의 일 실시예에 의한 방향성 전기강판은 전기강판의 표면에 형성된 포스테라이트 층, 포스테라이트 층에 압연방향에 수직한 방향으로 형성된 그루브 및 그루브 상단을 기점으로 상기 전기강판의 양 끝단 방향으로 상기 그루브 폭의 1.1 내지 1.3 배의 폭으로 형성된 포스테라이트 하소층을 포함한다.
