Abstract

UN CARGADOR DE HORNO CON ALIMENTACION POR GRAVEDAD DE UN FLUJO DE MASA QUE COMPRENDE UN CONDUCTO (51) HUECO ALARGADO ORIENTADO VERTICALMENTE QUE ESTA ASOCIADO CON UNA CUBIERTA (30) PERFORADA RESISTENTE AL CALOR ADAPTADA PARA ESTAR SITUADA ESENCIALMENTE EN CONTACTO CON LA SUPERFICIE SUPERIOR DE UN BAÑO DE METAL FUNDIDO (23) EN UN POZO DE CARGA (10) DE UN HORNO DE FUSION DE METAL (11). LA CHATARRA (80) CARGADA EN EL CONDUCTO (51) SE ACUMULA ENCIMA DE LA SUPERFICIE DEL BAÑO DE METAL FUNDIDO (23), DADO QUE LA APERTURA INFERIOR (52) DEL CONDUCTO SE COMUNICA CON LA APERTURA DE LA CUBIERTA DEL POZO DE CARGA (33) Y PERMITE QUE LA CHATARRA CAIGA POR GRAVEDAD DIRECTAMENTE DENTRO DEL METAL FUNDIDO DE EL POZO DE CARGA (10).
