    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.

    Abstract: The present invention relates to a direct smelting plant and a direct smelting process for producing molten metal from a metalliferous feed material, such as ores, partly reduced ores, and metal-containing waste streams, the latter of which comprising the steps of (a) pretreating metalliferous feed material in a pretreatment unit and producing pretreated feed material having a temperature of at least 200~C, (b) storing pretreated metalliferous feed material having a temperature of at least 200~C under pressure in a hot feed material storage means, (c) transferring pretreated metalliferous feed material having a temperature of at least 200~C under pressure in a hot feed material transfer line to a solids delivery means of a direct smelting vessel, and (d) delivering pretreated metalliferous feed material into the direct smelting vessel and smelting metalliferous feed material to molten metal in the vessel.

    Abstract: A process and apparatus for supplying solid feed materials for a direct smelting process to solids injection lances of a direct smelting vessel is disclosed. The feed materials supply apparatus includes a supply line (L) for conveying iron-containing material and solid carbonaceous material under pressure to solids injection lances ( 7 ), and the supply line includes a main feeder line section ( 15 ) and a plurality of branch line sections ( 17 ) extending from the main feeder line section. Each branch line section is connected to one solids injection lance for supplying iron-containing material and carbonaceous material to that lance. The apparatus further includes an assembly for dispensing iron-containing material under pressure into the main feeder line section of the supply line and an assembly for dispensing carbonaceous material under pressure into the main feeder line section of the supply line.

    Abstract: A direct smelting plant for producing molten metal from metalliferous feed material includes a pretreatment unit for pretreating metalliferous feed material and producing pretreated feed material, a direct smelting vessel for smelting pretreated metalliferous feed material to molten metal and a hot feed material transfer apparatus for transferring pretreated metalliferous feed material from the pretreatment unit to a solids delivery device of the direct smelting vessel. The transfer apparatus includes a hot feed material storage device, a hot feed material transfer line, device for unblocking the hot feed material transfer line and a pressurising device. The hot feed material transfer apparatus includes a device for returning pretreated metalliferous feed material to the pretreatment unit.
