Abstract

SE INTRODUCEN OXIDOS DE HIERRO REDUCIDOS PREVIAMENTE EN UN RECIPIENTE DE FUNDICION (1) PARA PRODUCIR HIERRO O ACERO DIRIGIENDO UN GAS LIBRE REDUCTOR Y CALIENTE DESDE EL RECIPIENTE (1) A UN CONDUCTO ELEVADOR VERTICAL (8) SIN UN ENFRIAMIENTO SUSTANCIAL DEL GAS LIBRE Y, POR MEDIO DE UNA ENTRADA (16), EL OXIDO DE HIERRO EN PARTICULAS QUE CONTIENE EL MATERIAL ES ARRASTRADO EN EL GAS LIBRE REDUCTOR Y CALIENTE CONFORME EL GAS ES LLEVADO HACIA ARRIBA A TRAVES DEL CONDUCTO (8). EL AIRE CALIENTE CALIENTA EL MATERIAL ARRASTRADO A UNA TEMPERATURA A LA QUE TIENE LUGAR LA REDUCCION PARCIAL DEL OXIDO DE HIERRO, EL AIRE CALIENTE PIERDE ASI BASTANTE CALOR. PUEDEN INTRODUCIRSE MATERIALES ADICIONALES EN EL CONDUCTO (8) PARA EL ARRASTRE EN EL GAS. EL MATERIAL EN PARTICULAS SE SEPARA DEL GAS EN UN CICLON (9) Y EL MATERIAL SEPARADO REDUCIDO PARCIALMENTE SE INTRODUCE EN EL RECIPIENTE DE FUSION POR MEDIO DE UN CANAL (12). EL MATERIAL EN PARTICULAS, O PARTE DE EL, PUEDE RECICLARSE POR MEDIO DE UN CANAL (15) A TRAVES DEL CONDUCTO ELEVADOR VERTICAL ANTES DE QUE EL MATERIAL REDUCIDO PARCIALMENTE SE INTRODUZCA EN EL RECIPIENTE DE FUSION Y SOLO PARTE DEL GAS LIBRE REDUCTOR Y CALIENTE EMITIDO POR EL RECIPIENTE PUEDA DIRIGIRSE AL CONDUCTO.
