Definitions

  • the present invention relates to a device for supplying and exchanging a pouring tube for a metal pouring container from below, having a bottom wall furnished with a seat brick and an internal nozzle in refractory material, device in which a pouring tube, or an end of casting plate attached to an upper flange, is mounted on guides capable of transmitting an upward thrust force and of guiding their movement from a loading position to a service or closing position in the axis of the taphole of the container and from the service position to a release position, so as to allow the exchange of the tube without lifting the container.
  • the bottom of such a container generally comprises a seat brick in which is housed an internal nozzle delimiting a tap hole through which the molten steel contained in the container flows continuously in a casting mold.
  • the guide rails are parallel to each other and form at the entrance a slightly inclined plane with an angle which can be between 2 and 10 ° relative to the reference plane.
  • the reference plate and the internal nozzle constitute two separate contiguous parts mounted separately in the pouring channel.
  • the reference plate is locked in the frame of the device for supplying and exchanging a pouring tube before the latter is placed under the metallurgical container.
  • the locking is effected under the pressure exerted on the underside of the reference plate by a system of levers via the upper flange of the tube, so as to firmly apply its perfectly flat upper face to the lower face of the reference plate.
  • the assembly of a device for supplying and exchanging a pouring tube, against the bottom of the container is carried out by placing the device against the bottom of the container and fixing it with eyelet bolts. engaged in anchors attached to the container or centering bolts and sleeves.
  • the supply and exchange device does not yet carry the internal nozzle but the bottom of the container is equipped with a seat brick.
  • the internal nozzle is placed from the inside of the metallurgical container, through the opening in the seat brick, on the reference plate, in line with the annular groove left exposed by the central opening in the upper plate of the supply and exchange device fixed under the container.
  • the lower end of the internal nozzle is provided with a circumferential lip which is placed in the annular groove possibly covered with a binder not yet taken.
  • the present invention aims to remedy this drawback. It proposes a device for supplying and exchanging a pouring tube similar to that described in the first paragraph of this memo.
  • This device is characterized in that it comprises a seat formed by two fixed strips which are strictly rectilinear and parallel to each other, which seat is intended to receive the flat underside of a reference plate and to receive on either side of the latter, portions of plates intended to serve as extensions of the reference plate.
  • the reference plate has a length and a width higher than those of the upper flange of a pouring tube.
  • the reference plate is a flange of the internal nozzle projecting from the tap hole.
  • the supply and exchange device comprises a U-shaped frame, consisting of two legs which are engaged in stirrups arranged in the same vertical plane parallel to the direction of movement of the tube pouring and that is locked by tightening the base of the U connecting the two tabs, against the frame of the device using two eyelet bolts fitted with spring cartridges engaged in fixing notches.
  • the device for supplying and exchanging a pouring tube according to the present invention differs from the device described in the first paragraph of this specification by the fact that the internal nozzle integral with the reference plate is mounted in the front device. its attachment to the bottom of the metallurgical container.
  • the reference plate is locked under the pressure exerted on its upper face by shoulders of the frame which are folded around an axis parallel to the direction of movement of the pouring tube, so as to firmly apply the perfectly flat underside of the reference plate on the seat consisting of two perfectly straight and parallel strips.
  • the legs of the frame are provided with stiffeners. They transmit a push downwards, in line with shoulders, on the upper face of the flange of the internal nozzle which protrudes from the tap hole.
  • the perfectly flat underside of the flange of the overflowing internal nozzle rests on the seat of the supply and exchange device, seat made up of two perfectly rectilinear and parallel strips. On these two strips are fixed on either side of the seat reserved for the reference plate, the plate portions intended to serve as extensions of the reference plate.
  • the mounting of the device against the bottom of the metallurgical container is similar to that described in the first paragraph with the particularity that at the time of mounting the device is equipped with the internal nozzle and the bottom of the container does not include a seat brick.
  • a device for supplying and exchanging 1 of a pouring tube 2 comprises a frame 3 on which is mounted a base plate 4 provided, opposite the tap hole 5, with a square window 6 and a U-shaped frame 7.
  • the frame 7 comprises two parallel legs 8 which are introduced into stirrups 9 fixed on the plate 4, in the same vertical plane parallel to the direction of movement of the tube casting 2 along guide rails 10.
  • the legs 8 are reinforced by stiffeners 34.
  • the frame 7 is foldable upwards and can pivot around the stirrups 9 forming hinges. It is intended to lock a reference plate, in particular a flange 11 of an internal nozzle 12, which flange projects beyond the tap hole 5.
  • the flange 11 or reference plate is applied downwards against a seat formed in the supply and exchange device 1 of a pouring tube 2. This seat is formed by two fixed strips 15 and 16, strictly rectilinear and parallel between they. ( Figure 4)
  • the guide rails determine the trajectory of the pouring tubes 2, 2 ′ moved by the action of pneumatic cylinders 29, 30 in a direction perpendicular to the axis (I, I ′) of the tap hole 5, from a position of loading towards a service or closing position in the axis (I, I ′) of the tap hole 5 and from the service position towards a release position, so as to allow the exchange of the tube 2 without lifting the container or container 19.
  • Figure 3
  • the upper flanges 37 of the pouring tubes are moved in translation along the reference plate by a pair of pneumatic cylinders 29 and 30 arranged parallel to each other, in order to provide the force necessary for allow rapid loading of the pouring tube 2 by making the best use of the small space available in height.
  • the rods 27 and 28 of the jacks 29 and 30 are interconnected by a movable frame 33 carrying a retractable pusher arm 25.
  • the internal nozzle 12 is mounted on the supply and exchange device before the latter is detachably mounted under a container 19.
  • the flange 11 of the internal nozzle 12 is embedded in the window 6 provided in the base plate 4 carried by the chassis 3 of the supply and exchange device and rests by its strictly planar lower face on the two strips 15, 16 strictly rectilinear and parallel so as to form a reference plane.
  • a folding frame 7 makes it possible to lock the flange 11 of the internal nozzle 12 in the window 6 of the base shelf 4, by the application of a downward thrust, by means of shoulders 24 acting on the upper face of the flange 11 of the internal nozzle 12 so as to apply it firmly against the seat consisting of two strips 15 and 16 perfectly rectilinear and parallel.
  • This supply and exchange device is detachably fixed under the container 19. For this purpose, it is applied upwards under the container so as to introduce the internal nozzle 12 into a wide opening in the bottom wall of the container 19.
  • the supply and exchange device is fixed under the container 19 using eyelet bolts 31 which are engaged in anchoring lugs 22 fixed to the container 19 as illustrated in figure 5.
  • the bottom of the container 19 thus comprises the internal nozzle 12 but not yet of a seat brick.
  • a seat brick 32 by having on each side of the internal nozzle 12 a refractory block constituting one half of the seat brick 32. Instead of putting in place half-blocks, we can also prepare a formwork and grout the refractory concrete around the internal nozzle 12.
