Abstract: The present invention relates to an apparatus for injecting gas into a vessel. The apparatus may include a 5 gas flow duct and a central body within a forward end region of the duct. The central body and the gas flow duct form an annular nozzle for the discharge of gas from the duct. A plurality of flow directing vanes are disposed about the central body to impart swirl to a gas flow 10 through the nozzle. The flow directing vanes have substantially straight leading end portions radiating outwardly from the central body and extending along the duct. The vanes also have substantially helical trailing end portions extending helically about the central body 15 toward the front end of the duct and transition portions joining the leading end portions to the trailing end portions. The transition portions are shaped so as to merge smoothly with both the leading end portions and the trailing end portions and to smoothly and progressively 20 change shape between them.

Abstract: A direct smelting plant for producing molten metal from a metalliferous feed material using a molten bath based direct smelting process is disclosed. The plant includes a gas delivery duct assembly extending from a gas supply location away from the vessel to deliver oxygen-containing gas to gas injection lances extending into a direct smelting vessel. The gas delivery duct assembly includes a single gas delivery main connected to the gas injection lances to supply oxygen-containing gas to the gas injection lances. The gas delivery main is located at a height above a lower half of the vessel.
