Abstract

Un método para fabricar un producto de acero al silicio orientado con elevada densidad de flujo magnético que comprende los siguientes procedimientos: 1) fusión y colada, en que el acero al silicio orientado está formado, en peso, por un 0,035-0,065% de C, un 2,9~4,0% de Si, un 0,05~0,20% de Mn, un 0,005~0,01 % de S, un 0,015~0,035% de Al, un 0,004~0,009% de N, un 0,005~0,090% de Sn, un 0,200~0,800% de Nb, siendo el resto Fe; y tras la fusión, el acero se refina secundariamente y se somete a colada continua para dar lugar a planchas de acero; 2) laminado en caliente; 3) normalizado; 4) laminado en frío; 5) recocido de descarburación; 6) revestido con MgO; 7) recocido a temperatura elevada; se calientan dichas chapas hasta 700~900 °C y posteriormente se calientan secundariamente hasta 1200 °C a una tasa de aumento de la temperatura de 9~17 °C/h y se mantienen a 1200 °C durante 20 h; 8) revestimiento de una capa de aislamiento. De acuerdo con la presente invención, se pueden someter las chapas de acero a nitruración completa durante el recocido a temperatura elevada, lo que puede garantizar que tenga lugar una re-cristalización secundaria de manera perfecta y, de este modo, se pueden conseguir las chapas de acero al silicio orientado con elevada densidad de flujo magnético. La presente invención soluciona el problema de la nitruración que se encuentra en la producción de acero al silicio orientado de alta inducción magnética por la técnica de calentar las planchas de acero a una temperatura más reducida.
