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 direct smelting process for producing iron and/or ferroalloys is disclosed . The process operates on a commercial scale in a metallurgical vessel that ha s a hearth, side walls, and a roof, and a minimum width dimension of the interior of the hearth of at least 4 meters. The process is a molten bath- based process and includes supplying ferruginous material, carbonaceous material, and fluxes into the vessel and smelting ferruginous feed material to molten metal in the molten bath and generating gases in the bath. The proces s also includes injecting jets of oxygen-containing gas being air or air with up to 50% oxygen through 3 or more lances into a space above the quiescent surface of the molten bath (the "top space") and combusting gases generated in the process and generating upward movement of molten material from the molte n bath into the top space to facilitate heat transfer to the bath and to minimise heat loss from the vessel. The process is characterised by entraini ng a volume of top space gas into the jets of oxygen-containing gas injected in to the vessel that is 2-6 times the volume of the injected gas.

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.
