Abstract

Un acero al silicio de grano orientado, rayado con láser, resistente al recocido de eliminación de tensiones y su método de fabricación. Se adopta la corrosión con láser para formar ranuras lineales paralelas (20) en uno o ambos lados del acero al silicio de grano orientado (10). Las ranuras lineales (20) son perpendiculares o en ángulo con respecto a la dirección de laminación de la placa de acero. La altura máxima de las protuberancias del borde de las ranuras lineales no es mayor que 5 µm, la altura máxima de las salpicaduras en las áreas no corroídas entre las ranuras lineales (20) adyacentes no es superior a 5 µm, y la proporción del área ocupada por las salpicaduras en la vecindad de las ranuras lineales (20) no es mayor que el 5%. El acero tiene un costo de fabricación bajo, y el efecto de corrosión del acero terminado no desaparece durante el proceso de recocido de eliminación de tensiones. El acero es adecuado para la fabricación de transformadores de núcleo de hierro bobinado.
