摘要： An apparatus for injecting gas into a metallurgical vessel is disclosed. The apparatus comprises a gas flow duct, an elongate central tubular structure extending within the gas flow duct, a plurality of flow directing swirl vanes, inflow and outflow cooling water passages within the central structure, and a nose portion provided with one or more water cooling passages. The flow directing vanes are provided with internal water cooling vane passages. In use, water flow is communicated through the vane passages from the water inflow passage in the central structure to the water flow passage in the nose portion of the central structure such that at least some of the inflowing water will pass successively through the vane passages and the nose passage or passages and thence to the outflow passage.

摘要： A molten bath-based direct smelting process for producing ferrous metal from a ferrous feed material is disclosed. The process is characterised by injecting pre-heated air downwardly into metallurgical vessel at an angle of 20 to 90 DEG C relative to a horizontal axis and at a temperature of 800-1400 DEG C and at a velocity of 200-600 m/s via at least one lance (27). This step forces molten material in the region of a lower end of the lance away from the lance and forming a "free" space around the lower end of the lance that has a concentration of molten material that is lower than the molten material concentration in the raised bath. The process is further characterised in that the lance is located so that: (i) the lance extends into the vessel a distance that is at least the outer diameter of the lower end of the lance; and (ii) the lower end of the lance is at least 3 times the outer diameter of the lower end of the lance above a quiescent surface of the molten bath.

摘要： 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 40m/s through at least one downwardly extending solids injection lance having a delivery tube of internal diameter of 40-200mm 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 Nm3/s/m2 within the molten bath at least in part by reactions of injected material in the bath. The gas flow 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.

摘要： A direct smelting process for producing iron and/or ferroalloys is disclosed. The process operates on a commercial scale in a metallurgical vessel that has 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 process 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 molten 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 entraining a volume of top space gas into the jets of oxygen-containing gas injected into the vessel that is 2-6 times the volume of the injected gas.

摘要： Method of constructing and installing a direct smelting unit comprising a smelting vessel (11). The vessel is prefabricated off site in three modules (11A, 11B, 11C) which are then transported to the installation site where they are hoisted by a crane and deposited sequentially on top of one another and joined together by welding to form a unitary vessel. The vessel modules are prefabricated so as to be internally lined with water cooling panels connected to water inlet and outlet connectors (62) on the exterior of the circumferential wall sections of those modules. A vessel access tower is formed in modules brought together to envelop the tower and carrying water supply and return piping which is connected to the water inlet and outlet connectors (62) of the cooling panels.
