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 direct smelting plant that includes an effective and reliable solids feed means for injecting solid feed materials, particularly carbonaceous material, into a direct smelting vessel of the plant is disclosed. The solid feed means is characterised by independent supply of carbonaceous material to injection lances. The independent supply of carbonaceous material minimises the possible adverse impact of a a breakdown of one or more than one lance or a breakdown of the carbonaceous material injection means for that lance or lances.

Abstract: A molten-bath based direct smelting process and apparatus for producing metals from a ferrous material is disclosed. The process includes injecting feed materials being solid material and carrier gas into a molten bath at a velocity of at least 40 m/s through at least one downwardly extending solids injection lance having a delivery tube of internal diameter of 40-200 mm that is located so that a central axis of an outlet end of the lance is at an angle of 20 to 90 degrees to a horizontal axis. The feed materials injection generates a superficial gas flow of at least 0.04 Nm 3 /s/m 2 within the molten bath at least in part by reactions of injected material in the bath. The gas now causes molten material to be projected upwardly as splashes, droplets and streams and form an expanded molten bath zone, with the gas flow and the upwardly projected molten material causing substantial movement of material within the molten bath and strong mixing of the molten bath. The feed materials are selected so that, in an overall sense, the reactions of the feed materials in the molten bath are endothermic. The process also includes injecting an oxygen-containing gas into an upper region of the vessel via at least one oxygen gas injection lance and post-combusting combustible gases released from the molten bath.

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 with 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 includes 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.
