Abstract

Un procedimiento de fabricación de un acero al silicio de grano orientado que tiene excelente rendimiento magnético, que comprende las siguientes etapas 1) fundir y colar convencionalmente en una pieza en bruto de acero; 2) calentar la pieza en bruto de acero y laminar en caliente la misma dando una banda de acero; 3) procedimiento de normalización; llevando a cabo el procedimiento de normalización que tiene dos etapas, en el que la banda se calienta en primer lugar a 1100~1200°C, luego se enfría a 900~1000°C en el plazo de 50~200 s; y a continuación la banda se enfría rápidamente en agua que tiene una temperatura de 10~100; en este periodo se aplica una fuerza de tensión a la banda de acero, la banda de acero en el intervalo de temperatura de 900°C~500°C tiene un esfuerzo de 1~200 N/mm2; 4) laminar en frío, es decir, llevar a cabo un laminado en frío primario, o un laminado en frío doble con temple intermedio; 5) llevar a cabo un temple por recristalización primaria, luego recubrir un separador de temple cuya principal composición es MgO, para llevar a cabo el temple del producto final que comprende temple por recristalización secundaria y temple por purificación. La invención optimiza el contenido y la distribución de martensita en la placa de acero después de la normalización ajustando la fuerza de tensión aplicada a la placa de acero durante la transformación de normalización, de manera que se haga que el contenido de martensita en el intervalo asegure un mejor rendimiento magnético del producto final y optimice el rendimiento magnético de productos finales.
