摘要： Direct smelting plant for producing molten metal from a metalliferous feed material induces a smelting vessel (11) to hold a molten metal and slag bath beneath a hot gas space. Solids injection lances (27) extend downwardly and inwardly through side walls of the vessel and hot oxidising gas is directed downwardly into the gas space by a central vertical gas injection lance (26). The plant layout is divided into four functional zones spaced circumferentially around vessel (11) and radiating outwardly from the vessel. Zone 1 contains an overhead hot gas delivery duct (31) supplying gas to lance (26) and an offgas duct (32); Zone 2 contains a forehearth (19) and forehearth tapping launder (34); zone 3 contains slag notches (45) and slag launders (46); and Zone 4 contains a primary slag drain taphole and launder (48). This layout minimises the potential for interference between the transport of the hot gases, the metalliferous feed material, and the molten metal and slag.
摘要翻译：用于从含金属进料产生熔融金属的直接冶炼厂诱导熔融容器（11）将熔融金属和渣槽保持在热气体空间之下。固体注射枪（27）通过容器的侧壁向下和向内延伸，并且热氧化气体通过中心垂直气体喷射喷枪（26）向下指向气体空间。植物布置被分为在容器（11）周围周向隔开并从容器向外辐射的四个功能区域。区域1包括向喷枪（26）和废气管道（32）供应气体的塔顶热气体输送管道（31）; 区域2包含前炉（19）和前炉排水槽（34）; 区域3包含炉渣槽（45）和炉渣清洗器（46）; 第4区包含一个主要的排渣口和流槽（48）。这种布局最小化了热气体，含金属进料和熔融金属和炉渣的输送之间的干扰的可能性。
