Abstract

UN METODO Y APARATO PARA ALIMENTAR PARTICULAS QUE CONTIENEN HIERRO EN UN HORNO METALURGICO COMO ES UN HORNO DE ARCO ELECTRICO, QUE COMPRENDE UN RECIPIENTE QUE CONTIENE HIERRO FUNDIDO (10), QUE TIENE UNA PARED (12) QUE SE EXTIENDE SOBRE DICHO HIERRO FUNDIDO, UN ALIMENTADOR PREFERENTEMENTE DE TIPO TORNILLO (40) MONTADO EN EL EXTERIOR DE DICHO RECIPIENTE (10), UNA SALIDA DE ALIMENTACION (50) EN DICHA PARED PERFILADA PARA PERMITIR EL PASO DE DICHO ALIMENTADOR AL INTERIOR DE DICHO RECIPIENTE (10) Y SITUADO A UNA ALTURA TAL DE DICHO HIERRO FUNDIDO DE MANERA QUE LOS MATERIALES NO FUNDIDOS NO SE SALGAN DE DICHO HORNO A TRAVES DE DICHA SALIDA DURANTE EL FUNCIONAMIENTO NORMAL Y LA MANIOBRA DE DICHO HORNO; Y MEDIOS DE ACCIONAMIENTO (44) PARA EXTENDER DICHO ALIMENTADOR DE TIPO TORNILLO (40) DESDE UNA POSICION RETRAIDA FUERA DEL RECIPIENTE A UNA POSICION EXTENDIDA DENTRO DEL RECIPIENTE. DICHAS PARTICULAS QUE CONTIENEN HIERRO SE CARGAN EN UN PUNTO PROXIMO A DICHO HIERRO FUNDIDO Y A LA VEZ SON EMPUJADAS ENERGICAMENTE AL INTERIOR DE LA CAPA DE ESCORIA (20) EN LA DIRECCION DEL HIERRO FUNDIDO Y TAMBIEN DE LA ZONA MAS CALIENTE POR LO QUE SE INCREMENTA LA PRODUCTIVIDAD GLOBAL DEL HORNO.
