摘要： A device (10), for moving a runner (12) of a shaft furnace between an upper tapping floor level (42), where the runner is in an operational position in front of a taphole of the furnace, and a lower service level (40), where the runner is accessible for replacement. The device (10) comprises a first support (28) and a second support (34) forming a base member (38), a carrier member (20) for bearing the runner, the carrier member having a first and a second longitudinal portion, a first lifting member (22) connected via a first articulation (26) to the first longitudinal portion and via a second articulation (30) to the first support, and a second lifting member (24) connected via a third articulation (32) to the second longitudinal portion and via a fourth articulation (36) to the second support. The base member (38), the carrier member (20) and the first and second lifting members (22, 24) together with the four articulations (26, 30, 32, 36) form a four-bar equivalent mechanism. According to the invention, the device further comprises a traction link (90) connected via a fifth articulation (92) to the first lifting member (22) and via a sixth articulation (94) to the second lifting member (24). The axes of rotation of the fifth and sixth articulations (92, 94) remain above the plane defined by the axes of rotation of the second and fourth articulations (30, 36) when the carrier member (20) is in a lower position reached by approaching, taking or traversing a change point configuration.

摘要： A shaft furnace bleeder valve for controlling a gas outflow from the interior of a pressurized furnace to the ambient atmosphere through an exhaust conduit is proposed. The bleeder valve comprises a valve seat associated with the exhaust conduit, a movable closure member having a central closure surface and a peripheral sealing surface cooperating with the valve seat, the closure surface comprising a convex surface at least in proximity to the sealing surface. The valve further has an actuating mechanism, which is connected to the closure member for moving the closure member between a closed position on the valve seat and an open position distant from the valve seat. According to the invention, the closure member comprises a recurved deflection portion at the periphery of the peripheral sealing surface, the recurved deflection portion comprising a deflection surface inclined against the convex surface by an angle in the range of 30° to 70° for imparting to a gas outflow passing between the valve seat and the closure member a velocity component which is opposite to the initial opening movement of the closure member.

摘要： The invention relates to a hopper-loading method and installation. The inventive hopper-loading method comprises the following steps consisting in: emptying a lateral curtain of loose material above the hopper; dividing the aforementioned curtain into at least two partial flows, said division being made transversely to the lateral length of the curtain; and diverting each of said partial flows towards a different area of the hopper. According to the invention, a loose material distributor is intended to be disposed in the curtain of loose material being emptied from a loose material-routing means. The loose material distributor comprises: a casing with an upper opening; at least one wall which extends transversely in relation to the aforementioned curtain of material inside said casing, such as to sub-divide the casing into at least two compartments; and at least two emptying means, one of said emptying means being associated with each of the compartments of the casing. Moreover, the emptying means are directed such as to divert the material received in the respective compartments into a different area of the hopper.

摘要： The preliminary cleaning stage of a dust extraction installation for blast furnace gas consists of a large-size cyclone (10) which comprises a vertical pressurized tank (14). A blast furnace gas line (12) arriving from the blast furnace is connected to an axial delivery device (34, 26, 28, 50) situated at the upper end of the pressurized tank (14). The delivery device (34, 26, 28, 50) is configured such that it introduces the blast furnace gas into the pressurized tank (14) in an axial direction. A swirl device (58) with guide vanes (66) is positioned below the axial delivery device (34, 26, 28, 50) and causes the blast furnace gas which is axially introduced into the pressurized tank (14) to swirl about the axis (30) of said pressurized tank (14).

摘要： The invention concerns a device for distributing bulk materials comprising a suspension rotor (20) mounted in an outer frame (14). A chute (32) is provided with two suspension arms (34, 34'), each of which is connected to said suspension rotor by a suspension pin (36, 36'), so as to define on the suspension rotor (20) a pivot pin for the chute (32). A control lever (52, 52') is connected by an articulation (54, 54') to the suspension rotor (20). A driving mechanism transmits to the control lever (52, 52') a pivoting torque. A stop element (56, 56') of the control lever (52, 52') is supported on a counter-stop (58, 58') of the suspension arm (34, 34') so as to transmit the pivoting torque to the latter.

摘要： The invention concerns a device for dispensing bulk materials through a rotary chute with variable angle of inclination comprising an underslung rotor (22) mounted in a supporting frame (34) so as to rotate about a substantially vertical axis of rotation. The chute (14) is suspended to the rotor (22) so as to pivot about a substantially horizontal axis of suspension. A mechanism for pivoting the chute (14) comprises a hydraulic motor (64) mounted on the underslung rotor (22). A hydraulic connecting device (68) comprises a sleeve fixed in rotation (70) and a rotary sleeve (72) driven in rotation by the rotor (22). Said sleeves (70, 72) co-operate to connect the hydraulic motor (64) to a control hydraulic circuit fixed in rotation. A duct feeding (20) the chute (14) passes through the two sleeves (70, 72). The device can advantageously equip a shaft furnace.
