Abstract
Se proporciona un método de formación de ranuras lineales para formar ranuras lineales en la superficie de una lámina de acero, como una lámina de acero eléctrico de grano orientado, excelente en cuanto al efecto de mejorar la pérdida de hierro y en cuanto a la densidad de flujo magnético. Un método de formación de ranura lineal que incluye un proceso de formación de resistencia de formar una resistencia recubierta en una superficie de una lámina de acero, un proceso de irradiación láser de irradiar dos o más rayos de láser en la superficie de la lámina de acero, mientras que la exploración de los rayos de láser en una dirección de intersección de la dirección de laminación de la lámina de acero cíclicamente en una dirección de laminación de la lámina de acero para eliminar la resistencia recubierta de las porciones irradiadas con los rayos láser, y un proceso de grabado de la formación de ranuras lineales por el grabado de las porciones de la lámina de acero de la que la resistencia recubierta se ha eliminado, en donde, en el proceso de irradiación láser, el material resistente recubierto se elimina de forma continua en la dirección transversal de la lámina de acero utilizando los dos o más rayos láser irradiados desde los respectivos dispositivos de irradiación láser dispuestos en la dirección transversal de la lámina, y cuando el diámetro del punto de los rayos láser se define como F, los rayos láser se irradian desplazando los centros de dos de los rayos láser irradiados desde dos de los dispositivos de irradiación láser adyacentes entre sí en la dirección transversal de la lámina F multiplicados por 0.05 o más y 0.95 o menos en una dirección perpendicular a una dirección de exploración láser.
