摘要： A molten bath-based process for direct smelting metalliferous material and producing molten metal in a direct smelting vessel that contains a molten bath that has a metal layer that is at least 900 mm deep. The process includes selecting operating parameters of the process so that feed material (solid material and carrier gas) is injected from above the metal layer into the metal layer via at least one solids injection lance with sufficient momentum to penetrate to a depth of at least 100 mm below a nominal quiescent surface of the metal layer to cause upward movement of molten material and gas from the metal layer.

摘要： A method of cold starting a molten bath-based direct smelting process for producing molten iron in a vessel (3) is disclosed. The method includes a step of preheating the vessel before supplying solid feed materials into the vessel. The method also includes a subsequent step of supplying an oxygen-containing gas and solid feed materials including material for forming slag, iron-containing feed material, and carbonaceous material into the vessel and generating heat and forming a bath of molten material that includes molten iron and molten slag in the vessel. This step includes supplying feed materials to promote formation of molten slag over molten iron in an early stage of developing the molten bath

摘要： A molten bath-based direct smelting process for producing metals from metal oxides (including partially reduced metal oxides) is disclosed. The process includes causing upward movement of splashes, droplets, and streams of molten material from a metal layer (15) of the molten bath which:(i) promotes strong mixing of metal in a slag layer (16) of the molten bath so that the slag layer (16) is maintained in a strongly reducing condition leading to FeO levels below 8 wt % based on the total weight of the slag in the slag layer (16); and(ii) extends into a space above a nominal quiescent surface of the molten bath to form a transition zone (23).

摘要： A process and apparatus for direct smelting metalliferous material is disclosed. The invention concentrates injection of solid feed materials comprising metalliferous material and carbonaceous material into a direct smelting vessel during the course of the process into a relatively small region within a metal layer in a molten bath in the vessel in order to generate a substantial upward movement of molten material and gas from the metal layer into a region in the vessel that is above the molten bath. In particular, the invention injects the solid feed materials with sufficient momentum and/or velocity via an opposed pair of lances that are oriented within the vessel and arranged to form overlapping plumes of injected material in the molten bath.

摘要： A direct smelting plant for producing molten metal from a metalliferous feed material is disclosed. The plant includes a fixed smelting vessel to hold a molten bath of metal and slag and a gas space above the bath. The plant also includes means for supplying solids and gas feed materials to the vessel and for tapping molten material from the vessel. The plant also includes at least two platforms for supporting plant operators at different heights of the vessel. The metal tapping means and the slag tapping means are located so as to be accessible by plant operators on a cast house platform and the end metal tapping means and the end slag tapping means are located to be accessible by plant operators on an end tap platform that is at a lower height than the cast house platform.

摘要： A direct smelting process for producing metals from a metalliferous feed material is disclosed. The process includes forming a molten bath having a metal layer (15) and a slag layer (16) on the metal layer in a metallurgical vessel, injecting metalliferous feed material and solid carbonaceous material into the metal layer via a plurality of lances/tuyeres (11), and smelting metalliferous material to metal in the metal layer. The process also includes causing molten material to be projected as splashes, droplets, and streams into a top space above a nominal quiescent surface of the molten bath to form a transition zone (23). The process also includes injecting an oxygen-containing gas into the vessel via one or more than one lance/tuyere (13) to post-combust reaction gases released from the molten bath, whereby the ascending and thereafter descending splashes, droplets and streams of molten material in the transition zone facilitate heat transfer to the molten bath, and whereby the transition zone minimises heat loss from the vessel via the side walls in contact with the transition zone. The process is controlled by maintaining a high slag inventory and by reducing the heat loss from the vessel through the side walls being continuously splashed by the transition zone.
