Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE CHAPAS ELECTRICAS DE GRANO ORIENTADO CON UN ESPESOR DE BANDA FABRICADA EN LA ZONA DESDE 0,1 MM HASTA 0,5 MM A BASE DE LLANTON CON UNA COMPOSICION DE ALEACION DADA EN LA SOLICITUD DE PATENTE 1. LA INVENCION SE CARACTERIZA, PORQUE EL LLANTON POSEE JUNTO A MANGANESO Y COBRE UN CONTENIDO EN S ELEVADO Y UN CONTENIDO EN AL REDUCIDO, SE CALIENTA EL LLATON ANTES DE LA LAMINACION EN CALIENTE SOBRE UNA TEMPERATURA DESCENDIDA Y EN ESTA TEMPERATURA SE MANTIENE UN TIEMPO SUFICIENTEMENTE LARGO, SIENDO LA TEMPERATURA IGUAL A LA TEMPERATURA DE SOLUCION PARA EL SULFURO DE MANGANESO Y MAYOR QUE LA TEMPERATURA DE SOLUCION PARA EL SULFURO DE COBRE. EL LLANTON A CONTINUACION SE SOMETE EVENTUALMENTE A PROCESO DE LAMINADO EN CALIENTE PREVIO Y DESPUES SE FINALIZA EL PROCESO DE LAMINACION CON UNA TEMPERATURA DE LAMINADO FINAL DESCENDIDA, CON PREFERENCIA EN LA ZONA DESDE 900 HASTA 980 NADA SIENDO SEGUIDA DE UN RECOGIDO DE BANDA EN CALIENTE, CON PREFERENCIA EN LA ZONA DESDE 950 FECTUA LA LAMINACION EN FRIO EN UNA O DOS ETAPAS HASTA EL ESPESOR DE BANDA ACABADA, QUE SE CONSIGUE EN UN RECOCIDO DE RECRISTALIZACION CONOCIDO CON AL MISMO TIEMPO ENFRIAMIENTO, PARA LA APLICACION DE UN MEDIO DE SEPARACION, PARA CONSEGUIR EN EL RECOCIDO DE TEMPERATURA ELEVADA, ASI COMO EN EL RECOCIDO FINAL UNA CHAPA ELECTRICA DE GRANO ORIENTADO CON RECUBRIMIENTO AISLANTE. EN COMPARACION CON EL ESTADO TECNOLOGICO (RGO Y HGO) ESTAS CHAPAS (TGO) POSEEN UNAS PERDIDAS DE MAGNETIZACION MEJORADAS EN IGUALES CONDICIONES DE INDUCCION MAGNETICA.
