A direct reduction process is disclosed for iron oxide-containing materials. Synthesis gas is mixed with top gas produced during direct reduction of the iron oxide-containing materials and is used as reduction gas for directly reducing iron oxide-containing materials. In order to avoid or reduce metal dusting caused by an increased CO content of the reduction gas with a simple technique and equipment, the CO/CO2 ratio of the reduction gas is set at a predetermined value from 1 to 3.

Selon un procédé de réduction directe de matériaux contenant de l'oxyde de fer, on mélange du gaz de synthèse avec le gaz de gueulard produit pendant la réduction directe des matériaux contenant de l'oxyde de fer et on l'utilise comme gaz réducteur pour réduire directement les matériaux contenant de l'oxyde de fer. Afin d'éviter ou de réduire la décomposition des pièces métalliques causée par la teneur accrue en CO du gaz réducteur au moyen d'une technique et d'un équipement simples, le rapport CO/CO¿2? du gaz réducteur est réglé à une valeur prédéterminée comprise entre 1 et 3.
