摘要： The invention relates to a distribution chute (100) for a charging device of the rotary pivotal type, e.g. for a shaft furnace. The chute has an upstream mounting head (114) and a chute body (112) having an elongated downstream chute portion (116) with a longitudinal axis (L). It further includes at least two lateral suspensions (130) at the mounting head for mounting the chute to at least two corresponding support flanges of the charging device, the support flanges (140) being pivotable about the pivoting axis (B) in a raising sense (R) for raising the outlet (120) to a radially outermost charging position and in an opposite lowering sense for lowering the outlet to a radially innermost charging position with respect to the rotational axis. The suspensions (130) define a first and a second tilt points, which define, in turn, a tilt axis (T), about which the weight of the chute exerts torque onto support flanges of the charging device when the chute is mounted. The suspensions are configured in such a way that the ratio of the distance between the tilt axis and the pivoting axis to the distance between the first and second tilt points (which corresponds at least approximatively to the distance between the suspensions) amounts to 0.25 at most. According to the invention, the suspensions (130, 230, 330) are arranged so that an acute angle (a) from the longitudinal axis (L) to a virtual plane (P) through the tilt axis (T) and the center of gravity (G) of the chute has an angular measure in the raising sense (R) that has a small positive or a negligibly negative value.

摘要： The invention relates to an airlock with shutters (1), each shutter (2, 6) comprising at least one flap (3) and an electrically powered geared motor unit (10) to open and close said flap (3). This geared motor unit (10) comprises an output shaft capable of back-and-forth rotary movement associated with the opening and closing movement of said flap (3). The invention also relates to a method of operating an airlock with shutters (1), each shutter (2, 6) comprising at least one flap (3) arranged, in the closed position (3b), on a support frame (9), and an electrically powered geared motor unit (10). Said method comprises, in this order, the following steps: rotating the geared motor unit (10) in a first direction of rotation to generate the movement of the flap (3) for the opening thereof, blocking the rotation of the geared motor unit (10) at the end of the travel intended for opening the flap (3), rotating the geared motor unit (10) in the opposite direction to generate the movement of the flap (3) for the closing thereof, and blocking the rotation of the geared motor unit (10) at the end of the travel intended for closing the flap (3).

摘要： The invention concerns a charging installation for a shaft furnace, in particular for a blast furnace, and especially the lower sealing valve assembly thereof. The installation comprises at least two hoppers (22, 24) acting as lock hoppers for intermediate storage of charge material to be charged into the furnace. The lower sealing valve includes a lower sealing valve housing (100) arranged below the hoppers. The lower sealing valve housing (100) has at least two inlets (104, 106) respectively communicating with one of the hoppers and an outlet (107) for passing charge material into the furnace. Each inlet has a respective associated valve seat (112, 114) providing gas-tight sealing of the hoppers downstream. The lower sealing valve assembly further includes a sealing valve mechanism (140, 146, 150) for sealing the inlets, more specifically for closing the seats in technically gas-tight manner. According to the invention, the sealing valve mechanism (140, 146, 150) comprises a one-sided shutter (140) having a single sealing face (142) that cooperates with both of the at least two valve seats (112, 114), by virtue of the sealing valve mechanism being configured to bring the sealing face (142) of the one-sided shutter (140) into sealing contact in turn with each of the at least two valve seats (112, 114) for sealing the associated inlet (104, 106).

摘要： In a charging process of a shaft furnace, in particular of a blast furnace, batches of charge material are typically discharged in cyclical sequence into the furnace from a top hopper using a flow control valve. A method and system is proposed for adjusting the flow rate of charge material in such a process. According to the invention, a respective set of plural valve settings is stored for each batch, each valve setting of a set being associated to a different stage in the discharge of the batch. The method and system are configured to discharge a given batch so that, at each stage in the discharge of the given batch, the flow control valve operates at a constant valve opening according to the valve setting associated to that stage and so that an actual average flow rate at which charge material is discharged is determined for that stage. Further according to the invention, the method and system are configured to correct the plural valve settings offline and in function of the actual average flow rate determined for the associated stage.

摘要： The present invention proposes a charge distribution apparatus for a furnace comprising a charge distribution chute and a drive mechanism (12) with a first rotary drive shaft (14) for rotating the charge distribution chute and a second rotary drive shaft (16) for changing the angle of inclination of the charge distribution chute. The first and second drive shafts (14, 16) are coupled to respective first and second motors (18, 22) via a planetary gear mechanism (20) for driving the first and second drive shafts (14, 16). Each of the first and second rotary drive shafts (14, 16) have a first end (24, 24') with a first pinion (26, 26') interacting with the planetary gear mechanism (20) and a second end (28, 28') with a second pinion (30, 30') interacting with the charge distribution chute, the second end (28, 28') of the rotary drive shaft (14, 16) extending through a furnace wall (32) into the furnace, a primary sealing element (46, 46') being arranged between the furnace wall (32) and the rotary drive shaft (14, 16). The first rotary drive shaft (14) has a first rotation axis and the second rotary drive shaft (16) has a second rotation axis arranged parallel to and at a certain distance from the first rotation axis. A hollow socket (34, 34') is provided in the furnace wall (32) for each of the rotary drive shafts (14, 16), the socket (34, 34') comprising a first end (36, 36') outside the furnace and facing the drive mechanism (12) and a second end (38, 38') inside the furnace and facing the second pinion (30, 30'), the rotary drive shaft (14, 16) extending through the socket (34, 34'). The second end (38, 38') of the socket (34, 34') comprises a second end-wall (42, 42') wherein the primary sealing element (46, 46') is arranged between the socket (34, 34') and the rotary drive shaft (14, 16), so as to face the second pinion (30, 30'), the second pinion (30, 30') being removably connected to the rotary drive shaft (14, 16).
