Abstract

Proporcionar una lámina de acero eléctrico de grano orientado que pueda conseguir tanto una pérdida en el núcleo del transformador suficientemente baja como un ruido suficientemente bajo. Se describe una lámina de acero eléctrico de grano orientado que tiene un recubrimiento de tensión sobre una superficie de la misma y se somete a un tratamiento de refinado de dominio magnético mediante la generación de dominios de cierre lineales que se extienden en una dirección dentro de 30° de una dirección transversal, en la que un intervalo promedio L entre dominios de cierre adyacentes es de 15 mm o menos, una proporción de profundidad rd de una profundidad de los dominios de cierre a un espesor de lámina, calculado por una fórmula predeterminada, es de 35 % o más, y una fracción de volumen rv de los dominios de cierre, calculado por una fórmula predeterminada, es 0.30 % o más y 3.0 % o menos, y una proporción de área rs de los dominios de cierre, calculada mediante una fórmula predeterminada, es 0.50 % o más y 4.0 % o menos.
