Abstract
LA INVENCION TIENE COMO OBJETO UNA INSTALACION PARA LA PRODUCCION DE ACERO POR FUSION DE CHATARRA QUE COMPRENDE UN HORNO ELECTRICO (2''), MEDIOS DE SUMINISTRO DE LA CHATARRA EN FORMA DE CARGAS INDIVIDUALES DESTINADAS A SER INTRODUCIDAS, UNA TRAS OTRA, EN EL HORNO, Y UNA CAMARA DE PRECALENTAMIENTO (4) PARA PRECALENTAR CADA CARGA DE CHATARRA QUE CONSTITUYE EN SI MISMA UN RECIPIENTE DE CARGA ABIERTO EN SUS DOS EXTREMOS Y PROVISTO DE UN FONDO DESMONTABLE. ADEMAS, LA CAMARA ESTA MONTADA EN UN DISPOSITIVO TRANSPORTADOR QUE PERMITE SU DESPLAZAMIENTO ENTRE UNA POSICION DE PRECALENTAMIENTO EN LA QUE ESTA CONECTADA A UN CIRCUITO DE CIRCULACION DE GASES CALIENTES Y UNA POSICION DE VACIADO DE LA CARGA DE CHATARRA PRECALENTADA EN EL HORNO. SEGUN LA INVENCION, LA PARTE INFERIOR DE LA PARED LATERAL DE LA CAMARA (4) DE PRECALENTAMIENTO FORMA UNA FALDILLA (43) CON UNA ABERTURA AMPLIA DESCENDENTE Y LA CAMARA (4) ESTA ASOCIADA, EN LA POSICION DE PRECALENTAMIENTO, A UN DISPOSITIVO MOVIL (54) PARA ENGANCHAR OBTURADORAMENTE EL EXTREMO INFERIOR (42) DE DICHA FALDILLA (43) EN UNA PLACA DE BASE FIJA (3) CON UNA FORMA QUE SE ADAPTA A LA DEL EXTREMO INFERIOR, PARA CERRAR HERMETICAMENTE DICHA FALDILLA EN LA POSICION DE PRECALENTAMIENTO.
