Abstract

EN UN METODO DE PRODUCCION DE HIERRO Y ACERO, DE MINERALES DE HIERRO COMPUESTOS EN GRAN PARTE DE OXIDOS DE HIERRO, EN DONDE SE UTILIZA UN PROCESO DE REDUCCION DIRECTA PARA PRODUCIR UN PRODUCTO INTERMEDIO PARTICULADO SOLIDO, GENERALMENTE CONOCIDO COMO ESPONJA DE HIERRO O HIERRO REDUCIDO DIRECTO (DRI); TRANSPORTANDO NEUMATICAMENTE EL DRI EN UNA TUBERIA CERRADA DESDE EL REACTOR DE REDUCCION DEL PROCESO DE REDUCCION DIRECTO A LOS HORNOS METALURGICOS DONDE SE PRODUCE EL HIERRO LIQUIDO O EL ACERO, POR EJEMPLO HORNOS DE ARCO ELECTRICOS, HORNOS DE INDUCCION, HORNOS DE OXIGENO BASICO, ETC. O A PRENSAS BRIQUETADORAS PARA FORMAR BRIQUETAS DE DRI, O SIMPLEMENTE A UN SILO O A UN DEPOSITO DE ALMACENAMIENTO, O EN GENERAL A UNA FASE DE PROCESAMIENTO POSTERIOR DE DICHO DRI. CUANDO EL GAS PORTADOR VUELVE A CIRCULAR PARA SU REUTILIZACION, SORPRENDENTEMENTE SE PREFIERE EL AIRE COMO LA FUENTE DE DICHO GAS, ESPECIALMENTE PARA EL DRI DE CALOR DE REACCION. ESTE METODO TIENE UNA EFICACIA Y PRODUCTIVIDAD SUPERIOR YREDUCE EL CONSUMO DE ENERGIA TOTAL RELATIVA A LAS PLANTAS DE FABRICACION DE ACERO DE DRI ACTUALMENTE UTILIZADAS.
