Zusammenfassung:A direct reduction process comprises providing a shaft furnace of a direct reduction plant to reduce iron oxide with reducing gas; providing a direct reduced iron melting furnace; and coupling a discharge chute between a discharge exit of the direct reduced shaft furnace and an inlet of the direct reduced iron melting furnace; wherein direct reduced iron and the reducing gas from the shaft furnace flow through the discharge chute and the reducing gas controls the melting furnace atmosphere to reducing environment.
