Abstract

Método para producir material metálico de reducción directa, que comprende las etapas: a) cargar material metálico (142) a reducir en un espacio de horno (120); b) proporcionar calor y un gas reductor al espacio del horno (120), de manera que el gas reductor calentado caliente el material metálico cargado (142) a una temperatura suficientemente alta para que se reduzcan los óxidos metálicos presentes en el material metálico cargado (142), a su vez provocando la formación de vapor de agua; y c) condensar y recoger el vapor de agua formado en el paso b) en un condensador (280); El método se caracteriza porque, en el paso a), el material metálico (142) se carga sobre un piso permeable a los gases (151), porque el gas reductor circula en circuito cerrado hacia arriba a través de dicho piso (151), a través del material metálico cargado (142), y además a través de dicho condensador (280) y un dispositivo de circulación forzada de gas (250), y porque el método comprende además el paso d) suministrar gas reductor adicional para lograr y/o mantener una presión predeterminada en dicho espacio del horno (120). La invención también se refiere a un sistema.
