Abstract
METODO Y APARATO PARA REDUCIR OXIDOS DE HIERRO A ESPONJA DE HIERRO, USANDO UN MATERIAL CARBONOSO SOLIDO COMO COMBUSTIBLE Y COMO REDUCTOR. EL PROCESO CONSISTE EN ALIMENTAR MATERIALES QUE CONTIENEN OXIDOS DE HIERRO A REDUCIR Y MATERIAL CARBONOSO SOLIDO EN UN HORNO GIRATORIO. DE LOS PRODUCTOS SOLIDOS OBTENIDOS EN LA DESCARGA DEL HORNO SE SEPARA EL AGENTE REDUCTOR COQUIZADO Y SE HACE REGRESAR AL HORNO DE NUEVO, DESCARGANDOSE SOBRE EL LECHO DE SOLIDOS FORMADO POR LOS OXIDOS DE HIERRO Y EL MATERIAL CARBONOSO. EL APARATO CONSTA DE UN HORNO GIRATORIO (6) DE REDUCCION PROVISTO DE UN EXTREMO DE ALIMENTACION (6A); DE UN ENFRIADOR ROTATIVO (15) AISLADO DE LA ATMOSFERA AMBIENTE; DE SEPARADORES MAGNETICOS (19,20) DONDE SE RECOGE EL AGENTE REDUCTOR COQUIZADOR.
