摘要： A charging device for a shaft furnace, which comprises at least one charging hopper having a discharge orifice arranged in a position off-centre with respect to the central axis of the shaft furnace, and a material distribution device arranged below this hopper. The material distribution device comprises a feed channel coaxial with the central axis of the furnace and a rotatable, pivotable chute, which is arranged below the feed channel for distributing a charge in the shaft furnace. The charging device also comprises a connecting box in the shape of a funnel, arranged between the material distribution device and the charging hopper. The connecting box possesses a lower central outlet communicating with the charging hopper and at least one upper inlet which is arranged off-centre with respect to the central axis of the furnace and communicates with the discharge orifice of the hopper. According to the invention, the charging device comprises at least one spreader situated upstream of the distribution device, on the trajectory of the material discharged from the discharge orifice. The spreader enables a flow of material to be dispersed to both sides of the feed channel.

摘要： The invention concerns a lower sealing valve assembly for a shaft furnace charging installation. It comprises a lower sealing valve housing (1) with a lower outlet (7) through which charge material can freely drop onto a distribution device. The housing has at least one upper inlet (4, 6) for communicating with an outlet of a hopper arranged above the housing. Each inlet has an associated valve seat (12, 14) that is arranged inside the lower sealing valve housing and turned towards the interior of the housing (1). A shutter (40) is operatively connected to an actuation mechanism (46, 50) for moving the shutter into and out of sealing contact with the valve seat. The valve actuation mechanism comprises a turn-slide cylindric joint (50) having a typically vertical joint axis (51) for swiveling the shutter (40) in a plane perpendicular to the joint axis (51) inside the lower sealing valve housing and for translating the shutter (40) up and down along the joint axis (51). According to the invention, the cylindric joint comprises a shaft (52) that is axially fixed and rotatably in a hollow sleeve (54), which in turn is axially slideable in an outer shell (56) that is fixed to the housing. Further according to the invention, the mechanism comprises: a first hydraulic cylinder (72), which is connected on one side to the shell (56) and on the other side to the hollow sleeve (54) to impart axial translation to the sleeve and therewith to the shaft along the joint axis (51); and: a second hydraulic cylinder (74), which is hinged on one side to the sleeve and on the other side to the shaft, to impart rotation to the shaft (52) and about the joint axis (51).

摘要： A multiple hopper charging installation (10, 10') for a shaft furnace comprises a rotary distribution device (14) for distributing bulk material in the shaft furnace (12) by rotating a distribution member about a central axis (A) of the shaft furnace and at least two hoppers (20, 22) arranged in parallel and offset from the central axis above the rotary distribution device. Each hopper has a lower funnel part (76) ending in an outlet portion (78) and each hopper has a material gate valve (82) with a shutter member (84) associated to its outlet portion. According to the invention, each funnel part (76) is configured asymmetrically with its outlet portion (78) being eccentric and arranged proximate to the central axis (A), each outlet portion (78) is oriented vertically so as to produce a substantially vertical outflow (140) of bulk material and each material gate valve (82) is configured with its shutter member (84) opening in a direction pointing away from the central axis (A) such that any partial valve opening area is located on the side of the associated outlet portion (78) proximate to the central axis (A).

摘要： The invention relates to a novel preheating device and a method for preheating an iron scrap mixture before delivering the scrap iron into a metallurgical furnace. The invention primarily makes use of heat which is recovered from hot waste gasses that have been emitted from the furnace outlet. The invention is also provided for simultaneously reducing contaminated substances from the scrap iron and from the waste gasses with a downward stream comprised of the hot waste gas and of the downward falling scrap iron which flow in the same direction. The invention has a chamber comprising an upper compartment having a cold scrap iron feed provided for dumping cold scrap iron into the upper compartment and a hot gas inlet which is flow-connected to the furnace outlet. The chamber also has a lower compartment with an unloading mechanism for the heated scrap iron in order to forcibly deliver the heated scrap iron into the furnace and has a waste gas outlet which is flow-connected to a vacuum outlet and provided for evacuating the used waste gas. Gates which allow gas to pass through are arranged between each chamber compartment and sequentially operate between a closed gate position and an open gate position for receiving a scrap iron charge which is delivered in a closed gate position from the cold scrap iron feed in the same direction by means of gravity. During a predetermined hold period, the scrap iron charge is stored while hot waste gas flows downward out of the hot gas inlet in the upper compartment, penetrates through the scrap iron charge and through the closed gate, and flows out of the waste gas outlet in the lower compartment. The gates mix the scrap iron when it falls and serve to control the gravitational downward movement of the scrap iron charge from the upper compartment to the lower compartment after the hold period has elapsed.

摘要： Facility for producing steel by melting scrap comprises an electric furnace (2'), means for supplying individual batches of scrap for charging one at a time into the furnace, and a preheating chamber (4) for preheating each batch of scrap and forming a batch container open at both ends and having a releasable bottom. Moreover, the chamber is mounted on a transporting device for movement between a first, preheating position, in which it is connected to a hot gas circulating circuit, and a second position in which it empties the batch of preheated scrap into the furnace. The lower portion of the side wall of the preheating chamber (4) forms a skirt (43) with a wide downwardly-directed opening, and said chamber (4) is combined, in the preheating position, with a movable device (54) for sealably engaging the lower end (42) of said skirt (43) with a stationary base plate (3) shaped to match said lower end (42), whereby said skirt is sealed in the preheating position.
