Abstract

Un método de formación de ranuras lineales para formar ranuras lineales en una superficie de lámina de acero utilizando grabado puede formar ranuras lineales de forma uniforme mientras que al mismo tiempo se suprime una disminución en la propiedad magnética de una lámina de acero eléctrico de grano orientado causada por irradiación láser para la eliminación de capa protectora. Un método de formación de ranuras lineales incluye: recubrir una superficie de una lámina de acero eléctrico de grano orientado con una capa protectora; llevar a cabo un barrido láser cíclicamente en una dirección de laminación de la lámina de acero eléctrico de grano orientado, el barrido láser es la aplicación de un láser mientras se barre el láser en una dirección que cruza la dirección de laminación para eliminar la capa protectora en una porción irradiada con el láser; y grabar la lámina de acero eléctrico de grano orientado en cada porción en la cual se elimina la capa protectora, para formar una ranura lineal. El espesor de recubrimiento de la capa protectora es de 0.5 µm a 10 µm, y la potencia del láser es de 1500 W o más.
