DIRECT REDUCED IRON DISCHARGE SYSTEM

摘要

A method and apparatus for simultaneously supplying varying proportions of hot and cold direct reduced iron (DRI) material from a source of hot DRI for melting, storage, briquetting or transport. The system uses gravity to transport hot DRI material from a reduction furnace (10) to a furnace discharge section (12), which transports desired amounts to a cooling receptacle (20), and to a hot DRI vessel (30). The cooling section (20) of the apparatus is connected to the furnace discharge section (12) through a dynamic seal leg (14). The hot section (30) is also connected to the furnace discharge section (12) through a separate dynamic seal leg (14) and can feed a surge vessel (6), a briquetter (72), a storage vessel (60) or a melting furnace (70). The method of operation is also disclosed.
