Abstract

UN HORNO DE CALENTAMIENTO POR INDUCCION (10) QUE CONSTA DE UN CONJUNTO DE BOBINA DE INDUCCION (16) Y DE UN CUCHARON (12) QUE TIENE UNA CUBIERTA METALICA (14) QUE SOPORTA METAL DE SOSTEN DE CRISOL A CALENTAR POR EL HORNO. EL CUCHARON (12) SE SEPARA FACILMENTE DEL CONJUNTO DE BOBINA DE INDUCCION (16) DE MODO QUE EL METAL CALENTADO SE PUEDA MOVER DE FORMA CONVENIENTE Y FIDEDIGNA ENTRE LAS ESTACIONES OPERATIVAS. EL CONJUNTO DE BOBINA DE INDUCCION (16) TIENE UNA LONGITUD PRESELECCIONADA QUE ES MENOR QUE LA LONGITUD DE LA CUBIERTA (14). EL CONJUNTO DE BOBINA DE INDUCCION (16) RODEA, PERO NO TOCA, LA CUBIERTA (14) Y GENERA UN CAMPO DE INDUCCION ELECTROMAGNETICO. EL CONJUNTO DE BOBINA DE INDUCCION (16) CONSTA DE UNA BOBINA (10), UNA CULATA SUPERIOR Y OTRA INFERIOR (28 Y 34) Y UNA CULATA INTERMEDIA (40) QUE SE PUEDE EXTENDER JUNTO CON LA BOBINA (20) LAS CULATAS SUPERIOR E INFERIOR (28 Y 34) SE ENCUENTRAN SEPARADAS UNA DE LA OTRA Y ACOPLADAS ELECTROMAGNETICAMENTE ENTRE SI A TRAVES DE LA CULATA INTERMEDIA (40). CADA CULATA SUPERIOR, INFERIOR E INTERMEDIA (28, 34 Y 40) CONTIENE PREFERENTEMENTE UNAS LAMINAS APILADAS (72 Y 74) FORMADAS DE HOJAS DE MATERIAL FERROSO.
