Abstract: A direct smelting vessel which is adapted to contain a molten bath of metal and slag is disclosed. The vessel includes an off-gas duct that has: (a) a first section which has a relatively slight upward inclination to the horizontal from an inlet end of the first section; and (b) a second section which extends upwardly from an upper end of the first section at a relatively steep inclination to the horizontal.

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 (13) 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.(FIG 1)

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 (2 3) 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 jack et (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 provided, which involves forming a molten bath in a metallurgical vessel, supplying feed materials, injecting oxygen containing gas, generating upward movement of the molten material from the molten bath, wherein the oxygen-containing gas is injected by three or more lances, and entraining into the jets of oxygen containing gas a volume of top space gas 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.
