Abstract

SE DESCRIBE UN PROCEDIMIENTO DE PRODUCCION DIRECTA DE HIERRO COLADO, A PARTIR DE UN MINERAL DE HIERRO, EN UN APARATO QUE TIENE DOS CAMARAS COMUNICADAS Y COMPRENDIENDO LAS SIGUIENTES FASES: PRERREDUCCION Y PRECALENTAMIENTO HASTA EL PUNTO DE MOLDEO DEL MINERAL FERRUGINOSO, EN UNA PRIMERA CAMARA PRACTICAMENTE CILINDRICA; REDUCCION FINAL, CEMENTACION Y MOLDEO DEL HIERRO RESULTANTE, EN UNA SEGUNDA CAMARA DISPUESTA POR DEBAJO DE LA PRIMERA, EN DONDE EL CARBON Y EL OXIGENO INYECTADOS EN LA SEGUNDA CAMARA PRODUCEN UN GAS REDUCTOR, SIMULTANEAMENTE EN LA PRIMERA Y EN LA SEGUNDA CAMARAS. DICHO PROCEDIMIENTO SE CARACTERIZA PORQUE EL MINERAL FERRUGINOSO Y EL OXIGENO SE INTRODUCEN EN DICHA PRIMERA CAMARA A TRAVES DE LAS PAREDES LATERALES DE LA MISMA, SIMULTANEAMENTE PERO POR SEPARADO; EL OXIGENO SE INTRODUCE A UNA VELOCIDAD INFERIOR O IGUAL A LA VELOCIDAD DE INTRODUCCION DEL MINERAL FERRUGINOSO; Y EL OXIGENO, EL CARBON Y EL FUNDENTE SON INTRODUCIDOS SIMULTANEAMENTE, PERO SEPARADAMENTE, POR LAS PAREDES LATERALES DE LA SEGUNDA CAMARA, DE FORMA INCLINADA HACIA EL FONDO Y EN DIRECCION HACIA EL CENTRO DE DICHA SEGUNDA CAMARA.
