Abstract: The invention relates to a sealing valve arrangement for a shaft furnace charging installation comprising a shutter (12) that cooperates with a valve seat (10) and a shutter-actuating device for moving the shutter (12) between a closed position in sealing contact with the valve seat (10) and an open position remote from the valve seat (10). According to the present invention, the shutter-actuating device comprises a tilting shaft (24) connected to the shutter (12), an electric motor (26) with an output shaft connected to the tilting shaft (24), and a braking device (30) associated with the electric motor (26). The braking device (30) is configured for, when engaged, preventing the output shaft of the electric motor (26) from rotating. The shutter-actuating device further comprises a transmission means (28) arranged between the output shaft of the electric motor (26) and the tilting shaft (24), wherein the transmission means (28) is configured for transmitting rotational movement of the output shaft of the electric motor (26) to the tilting shaft (24). The transmission means (28) comprises a backlash configured for having a predetermined amount of allowed rotation between the output shaft of the electric motor (26) and the tilting shaft (24).

Abstract: A charging system for a shaft smelt reduction furnace, comprising:a frame structure (30) for mounting on a top charge opening of a shaft smelt reduction vessel(12);a center shaft arrangement (32) supported by said frame structure (30) and configured to remove off-gasgases from the furnace and to introduce granular charge materials in order to form a stack (40) of materials in the furnace, the center shaft arrangement comprising: a center hood (34) for off-gas extraction; a pair of first feed channels (36, 36') for a first material, one on each side of said center hood;and a pair of second feed channels (38, 38') for a second material arranged on respective sides of thefirst feed channels; The center hood comprises a pair of facing off-gas panels (44, 44') defining an off-gas channel (46), each off-gas panel cooperating with a respective partition wall (48, 48') to define a respective first feed channel (36, 36'); and each partition wall (48, 48') cooperates with a respective outer wall (50, 50') to define a respective second feed channel (38, 38'). The partition walls (48, 48') comprise lower portions (54, 54') that extend towards each other below said center hood (34) to define a center feed passage (56), whereby material descending through the first feed channels may, before flowing through said center feed passage, accumulate on the lower portions (54, 54') according to the angle of repose of said material, thereby permitting self-adjustment of the first material stock-line in the shaft arrangement.

Abstract: The invention relates to a charging system (1) for a metallurgical furnace (100) that is elongate along a horizontal length direction (X) in that it has a longer dimension in the length direction (X) than in a horizontal width direction (Y) perpendicular thereto, the charging system (1) being adapted for feeding a plurality of materials to the metallurgical furnace (100). In order to provide a space-saving, simplified charging system for a furnace with an elongate cross-section, the invention provides that the charging system comprises: - a lock hopper (10) for receiving material, having an inlet sealing element (11) and an outlet sealing element (12), the lock hopper (10) being adapted to receive material through the inlet sealing element (11) when the inlet sealing element (11) is open, and being adapted to discharge material through the outlet sealing element (12) when the outlet sealing element (12) is open, the sealing elements (11, 12) being adapted to gas-tightly seal the lock hopper (10) when they are closed; - at least one process hopper (30) having a plurality of material chambers (31, 32, 33); - a transfer system (20) connecting the lock hopper (10) to each material chamber (31, 32, 33) and adapted to receive material from the lock hopper (10) through the outlet sealing element (12) and selectively transfer the received material from the lock hopper (10) to at least one selected material chamber (31, 32, 33) whereby different materials are transferable to different selected material chambers (31, 32, 33); and - a feeder system (40) connecting each material chamber (31, 32, 33) to the furnace (100), wherein the sealing elements (11, 12) are adapted to be opened alternatingly, so that the at least one process hopper (30) and the transfer system (20), downstream of the lock hopper (10), are separated by the sealing elements (11, 12) from an outside atmosphere, upstream of the lock hopper (10).
