Abstract

Un método para refinar granos de cristal gruesos en la superficie de silicio no orientado, que comprende las siguientes etapas: 1) fundir y moldear; las composiciones de acero al silicio no orientado cuyos porcentajes en peso son: C: 0.001 % ~ 0.005 %, Si: 0.1 % ~ 1.8 %, Mn: 0.10 % ~ 0.80 %, P = 0.04 %, Al: 0.20 % ~ 0.80 %, S = 0.005 %, N = 0.005 %, y el resto es Fe e inclusiones inevitables mínimas; el acero fundido de acuerdo con las anteriores composiciones experimenta fundido y tratamiento de refinación por RH y luego se moldea en lingotes de acero ; 2) se lamina al calor en láminas de acero; 3) normalización, la temperatura de normalización se controla en 800 ~ 900° C, el periodo de reacción de normalización se controla a 15 ~ 30 S, el contenido de oxígeno en el horno de normalización se controla a 0.5 % o menos, un índice de tamaño de grano máximo para promediar el tamaño de grano en la lámina de acero normalizada se controla por debajo de 3; y 4) se lava con ácido frío, se lamina en frío, se recuece, se recubre con el fin de obtener productos de acero al silicio no orientado. La invención, bajo condiciones existentes, puede refinar los granos de cristal gruesos en la superficie de acero al silicio no orientado, sin la adición de procedimientos de tratamiento por calor y sin un trabajo por calor paralelo.
