Abstract

SE PROPONE UN REFLUJO MAGNETICO PARA UN HORNO DE CRISOL DE INDUCCION, CON UN PAQUETE DE CHAPAS EN FORMA DE VARILLAS (9,19) PARA CONDUCIR EL FLUJO MAGNETICO ADECUADO, PRODUCIDO POR LA BOBINA (3) DEL HORNO DE CRISOL DE INDUCCION (1), EL CUAL SE COMPONE DE NUMEROSAS CHAPAS INDIVIDUALES AISLADAS ELECTRICAMENTE ENTRE SI. EL PAQUETE DE CHAPAS (9,19) PRESENTA EN SU SUPERFICIE PRINCIPAL ORIENTADA HACIA LA BOBINA DEL HORNO (3), UNA CONFIGURACION DIVIDIDA EN TRES PARTES DE TAL MODO QUE, UNA ZONA CENTRAL DEL PAQUETE DE CHAPAS, ES POSICIONABLE MUY CERCA DE LA BOBINA DEL HORNO, MIENTRAS QUE LA DISTANCIA ENTRE LOS CANTOS DE LAS CHAPAS INDIVIDUALES Y DE LA BOBINA DEL HORNO, CRECE HACIA LOS BORDES DE LAS ZONAS LATERALES DEL PAQUETE DE CHAPAS CONTIGUAS A LA ZONA CENTRAL, DE MODO QUE SE FORMAN PARALELOS AL EJE DEL HORNO, SECTORES DE ANGULO AGUDO EXENTAS DE CHAPAS, EN LOS DOS MARGENES DE LOS BORDES DEL REFLUJO, ORIENTADOS HACIA LA BOBINA DEL HORNO. CONSECUENTEMENTE ES EVITADA UNA INDUCCION PUNTUAL DE ALTA CAPACIDAD ESPECIFICA EN LOS MARGENES DE LOS BORDES DEL REFLUJO MAGNETICO, Y LA DISTRIBUCION TERMICA ES IGUALADA DENTRO DEL REFLUJO MAGNETICO.
