    Abstract: A lance (5) for injecting a feed material, preferably a solid feed material, into a metallurgical vessel, is disclosed. The lance comprises: an inlet (21) for introducing the feed material into the lance; an outlet (23) at a forward end of the lance (5) for discharging the feed material from the lance (5); a hollow elongate member (25) that defines a passageway (33) for the feed material between the inlet (21) and the outlet (23) and is adapted to be cooled by a first cooling fluid; and an outer jacket (35) positioned around a section of the length of the member (25) and is adapted to be cooled by a second cooling fluid.

    Abstract: A procedure for starting up a direct smelting process for producing iron from a metalliferous feed material in a metallurgical vessel is disclosed. The vessel is of the type which includes a plurality of feed material injection lances/tuyeres (11, 13). The start-up procedure includes the steps of: (a) preheating the vessel; (b) supplying a charge of molten iron to the vessel and forming a molten bath in the vessel, (c) supplying carbonaceous material and flux to the molten bath and injecting oxygen-containing gas through one or more than one feed material injection lance/tuyere and combusting carbon and bath derived gas (if present) and thereby heating the molten bath and generating slag; and (d) suppling metalliferous feed material to the vessel while continuing supply of carbonaceous material and flux and injection of oxygen-containing gas and smelting metalliferous feed material and producing molten iron and thereby completing the start-up procedure.

    Abstract: A vessel which produces metal from a metalliferous feed material by a direct smelting process is disclosed. The vessel contains a molten bath having a metal layer (15) and a slag layer (16) on the metal layer and has a gas continuous space (31) above the slag layer. The vessel includes a hearth formed of refractory material having a base (3) and sides (55) in contact wi th the molten metal and side walls (5) which extend upwardly from the sides (55 ) of the hearth and are in contact with the slag layer and the gas continuous space. The side walls that contact the gas continuous space include water cooled panels (57) and a layer of slag on the panels. The vessel also includ es one or more than one lance/tuyere (13) extending downwardly into the vessel and injecting an oxygen-containing gas into the vessel above the metal layer and a plurality of lances/tuyeres (11) injecting at least part of the metalliferous feed material and a carbonaceous material with a carrier gas into the molten bath so as to penetrate the metal layer.
