Abstract

Un método de fabricación de acero al silicio no orientado de alta eficiencia con excelente propiedad magnética, que comprende las siguientes etapas: 1) fundir y moldear; composiciones químicas de acero de silicio no orientado, cuyos porcentajes en peso son: C=0.0040%, Si:0.1~0.8, Al:0.002~1.0%, Mn:0.10~1.50%, Sb:0.04~0.08, S=0.0030%, N=0.0020%, Ti=0.0020%, y el resto es Fe y inclusiones inevitables; acero fundido de acuerdo con las composiciones anteriores se funde y luego se moldea en lingotes; 2) laminado al calor y decapado; la temperatura de calentamiento para la plancha es 11000° C~l150° C y la temperatura para finalizar el laminado es 860° C~920° C; después del laminado, el producto laminado al calor se enfría con aire, durante lo cual el tiempo de enfriamiento con aire t es: (2+30xSb%)s =t=7s; después de esto enrollado a una temperatura =720° C; 3) laminado al frío; laminado para formar la placa laminada al frío con espesor objetivo en una relación de reducción de 70~78%; 4) recocción; calentar la placa laminada al frío a 800~1000° C a índice de calentamiento de =15° C/s, y el tiempo de retención es 10~25s. Bajo la precondición para asegurar las propiedades magnéticas, esta invención implementa la fabricación de bajo coste de acero eléctrico de alta eficiencia al agregar elementos ventajosos para textura favorable durante la elaboración del acero, el control de contenidos de elementos adversos y la coordinación del tiempo de enfriamiento con control de aire durante laminado al calor con alta temperatura de enrollado.
