Abstract

La invención describe un acero al silicio de grano orientado con excelentes propiedades magnéticas y un método de fabricación del mismo. La presente invención obtiene el acero al silicio de grano orientado con excelentes propiedades magnéticas controlando la relación de áreas de granos de cristales pequeños con D < 5 mm en el producto terminado de acero al silicio de grano orientado para que no sea mayor que 3 %, y controlando la relación µl7/µl5 de la conductividad magnética bajo la inducción magnética de 1.7 T a la conductividad magnética bajo la inducción magnética de 1.5 T en el producto terminado de acero al silicio de grano orientado para que sea de 0.50 o más. Además, al utilizar una placa del acero al silicio de grano orientado con componentes adecuados y un paso de laminación en frío optimizado, la presente invención reduce efectivamente la temperatura de calentamiento de la placa y el costo de producción de la misma, y simultáneamente controla mejor el tamaño y la relación de los granos de los cristales en el producto terminado de acero al silicio de grano orientado y la conductividad magnética en cierto intervalo de inducción magnética, asegura que la recristalización tenga buena orientación de textura de Goss y finalmente obtiene de manera estable el producto de acero al silicio de grano orientado con excelentes propiedades magnéticas.
