Abstract
SE REFIERE A UN METODO Y SISTEMA PARA EL SUMINISTRO DE UNA CORRIENTE CONTINUA DE HIERRO ESPONJA CALIENTE DESDE UN HORNO DE CUBA DE REDUCCION DIRECTA O UN HORNO DE RECALENTAMIENTO DE HIERRO ESPONJA HASTA UN PUNTO FUERA DEL HORNO DE CUBA DE REDUCCION DIRECTA O EL HORNO DE RECALENTAMIENTO DE HIERRO ESPONJA, EN DONDE LA CORRIENTE DE HIERRO ESPONJA CALIENTE SE DIVIDE AL MENOS EN DOS CORRIENTES DE HIERRO ESPONJA CALIENTE. EL METODO COMPRENDE: A) PROPORCIONAR UNA PRIMERA CORRIENTE DE HIERRO ESPONJA CALIENTE QUE SE ENVIA CONTINUAMENTE A UNA PLANTA DE BRIQUETEADO EN CALIENTE POR GRAVEDAD EN UN SISTEMA DE DUCTO CERRADO; Y B) PROPORCIONAR UNA SEGUNDA CORRIENTE DE HIERRO ESPONJA CALIENTE QUE SE ENVIA CONTINUAMENTE A UN HORNO DE FUSION CONTIGUO, YA SEA POR GRAVEDAD EN UN SEGUNDO SISTEMA DE DUCTO CERRADO O, POR UNA COMBINACION DE GRAVEDAD EN EL SEGUNDO SISTEMA DE DUCTO CERRADO Y UN TRANSPORTADOR DE SOLIDOS DE CARGA GENERALMENTE HORIZONTAL. DE MANERA OPCIONAL UNA TERCERA CORRIENTE DE HIERRO ESPONJA CALIENTE SE EMPLEA PARA ALIMENTAR CONTINUAMENTE MULTIPLES RECIPIENTES DE TRANSPORTE CALIENTE. EL SISTEMA COMPRENDE LOS MEDIOS PARA PROPORCIONAR LAS DOS CORRIENTES DE HIERRO ESPONJA CALIENTE
