Abstract

Se proporciona una lámina de acero eléctrico no orientado sin defectos superficiales y un método de fabricación de la misma, el porcentaje en peso de la composición química de la lámina de acero eléctrico no orientado es C no es mayor del 0,005%, Si es 1,2-2,2%, Mn es 0,2-0,4%, P no es mayor del 0,2%, S no es mayor del 0,005%, Al es 0,2-0,6%, N no es mayor del 0,005%, O no es mayor del 0,005% y siendo el resto sustancialmente Fe, puede obtenerse una plancha mediante procesamiento previo del metal en caliente, fundición con un convertidor, refinado RH y colada continua y vertido, en que se controla la cantidad de agua de refrigeración secundaria, el caudal de agua del agua de refrigeración se controla a 100-190 l/min, el supercalentamiento promedio del acero líquido en el proceso de colada continua se controla a 10-45 °C; la plancha se calienta y se lamina en caliente; en que la temperatura de salida de la plancha del horno es 1050-1150 °C, la diferencia de temperatura entre dos puntos aleatorios en la dirección longitudinal cuando la plancha se calienta es menor de 25 °C, el proceso de laminado en caliente incluye un proceso de laminado rugoso y un proceso de alisado, la temperatura de entrada en el proceso de alisado no es menor de 970 °C; la lámina de acero eléctrico no orientado acabada se obtiene por decapado con ácido, laminado en frío, recocido y revestimiento. No se producen defectos de corrugación controlando la velocidad de refrigeración de la plancha en un proceso de colada continua y vertido, la diferencia de temperatura en la dirección longitudinal de la plancha en el horno de calentamiento, y controlando la caída de temperatura antes del alisado de la plancha.
