Abstract
La invención se refiere a un procedimiento de fabricación de chapas eléctricas con granos orientados, según el cual un desbaste se caliente a una temperatura inferior a la temperatura de solubilización del sulfuro de manganeso, pero superior a la temperatura de solubilización del sulfuro de cobre, y a continuación se lamina en caliente a una temperatura inicial de al menos 960ºC y a una temperatura final comprendida entre 880 y 1000ºC, hasta la obtención de un espesor final del fleje en caliente comprendido entre 1,5 y 7,0 mm. El fleje en caliente se vuelve a recocer durante 100 a 600 s a una temperatura de 880 a 1150º, enfriado y laminado en frío. _El fleje en caliente se somete entonces a un recocido de descarburación y de recristalización. Después de la aplicación de un agente separador que contiene MgO, el fleje en frío se vuelve a recocer a alta temperatura y se somete a un recocido final después de la aplicación de un revestimiento de aislamiento. La invención se caracteriza porque utiliza un desbaste de estructura de globulito de granos finos, en la que al menos 90% de los granos presentan un diámetro que se eleva como máximo a1/25 del espesor del desbaste y un factor de alargamiento de al menos 0,5.
