Definitions

  • the present invention relates to a device for supplying and exchanging a pouring tube with a movable attached plate for a closable steel or metallurgical container lined with a bottom plate of refractory material provided with a pouring orifice, by another pouring tube for the manufacture of blooms and small slabs, in particular in continuous casting distributors.
  • French patent N ° 2065592 (SCHLOEMANN AKTIENGESELLSCHAFT) describes a device making it possible to place in the extension of a pouring orifice of a metallurgical container interchangeable pouring tubes.
  • the pouring tubes intended to lead the molten metal into a mold or an ingot mold are wear parts highly stressed. They are so so that their service life limits the casting time.
  • British Patent No. 1,563,955 proposes a metallurgical container provided with a closure device and a pouring tube, through from which the molten metal flows to an intermediate container or to a mold having only a small section opening for introducing the pouring tube there.
  • a handling machine comprising guide means making it possible to move the tube along a substantially horizontal path and to rotate it from a substantially horizontal position to a vertical position so as to allow placement in a casting line without having to raise the intermediate distributor.
  • the pouring tube is put in place by fitting the mouth of the tube onto an insert constituted by an outer rim of the inner nozzle.
  • This operation requires the complete interruption of the pouring jet.
  • the connection thus obtained has the drawback of adversely affecting the tightness of the pouring channel and consequently the quality of the metal.
  • an inerting device for example with argon.
  • French patent No. 1 478 778 discloses a shutter in refractory material for metallurgical containers intended for continuous casting. It comprises a movable refractory plate capable of sliding, under the action of a jack, along an upper plate fixed in a position for closing the pouring orifice. Levers on which act at one end, springs apply, in sealed contact, the movable plate against the upper plate. Such a device makes it easy to replace the movable refractory plate with a sliding closure but does not allow the pouring tube to be replaced without raising the distributor.
  • the pouring tubes are applied tightly against the distributor by a lever arm articulated on a common cart.
  • Each lever is provided at its free end with a roller guided by a rail which is pushed down by a spring bearing against the casting enclosure.
  • the present invention aims to avoid having to interrupt the casting due to the raising of the intermediate distributor.
  • It relates to a device for supplying and exchanging a pouring tube with a movable added plate for a closable steel or metallurgical container lined with a bottom plate of refractory material provided with a pouring orifice, by another tube.
  • movable insert plate casting essentially characterized in that the plates mobile can be joined to each other by a common transverse rim perfectly united, so as to form a perfectly flat surface.
  • the guides are mounted at the end of levers intended to transmit the force provided by a spring acting on the opposite end in order to obtain a sealed contact between the reference plate and the movable plate - pouring tube assembly.
  • the reference plate and the attached movable plate intended to slide along a rectilinear trajectory along the reference plate advantageously form an inclined plane determined by the above-mentioned trajectory constituting the straight line of greatest slope.
  • the hydraulic cylinders ensuring the linear movement of the movable plates attached to the tubes and / or of obturation are arranged parallel to the path of the plates, behind the guide rails.
  • FIGS. 1 to 4 show a supply and loading device designated as a whole by the reference notation 1 of a reserve pouring tube 2 attached to a movable plate 3, replacing a worn tube 2 ′, attached to a movable plate 3 ', in the service position, and consisting of a main chassis 4 intended to be mounted under a tundish 5 in the vicinity of a tapping hole 7.
  • the distributor can possibly already be fitted with a sliding closure. This closure does not constitute not an obstacle to the direct attachment of the device 1 according to the invention.
  • the shutter is simply a stopper 7 '.
  • the pouring tubes 2, 2 ′ each attached to a movable plate 3, 3 ′, slide along a lower plate of the sliding closure device.
  • the reference plate 6 along which the supply and loading device 1 slides is a bottom plate of the distributor 5 or of the ladle.
  • the movable plate 3, 3 'attached to the pouring tube 2, 2' then serves to seal between the lower nozzle 8 and the reference plate 6 applied against the seat brick 8 'and the sealing collar.
  • the reference plate 6 is possibly formed of several independent refractory elements.
  • Two guide rails 9, 9 ′ having an inclined stroke relative to the reference plate 6, so as to approach the pouring orifice 7 make it possible to obtain a progressive tightening of the movable plate 3 of a tube of casting 2 against the reference plate 6.
  • the upward thrust is obtained by springs 10, 10 ', mounted at a respectable distance from the orifice of casting 7.
  • the guide rails 9, 9 ' are mounted at the end of levers 12, 12' each subjected to the end opposite to the action of the springs 10, 10 'moving it away ci of the enclosure 11 of the container 5.
  • the force exerted by the guide rails 9, 9 'on each of the movable plates associated with a pouring tube 2 moving along said rails 9, 9' supported increases as and as these come closer to the pouring orifice, 7.
  • This upward push applies in a sealed manner, the movable plates 3, 3 ′ of the worn pouring tube 2 ′ and respectively of the reserve tube 2 against the sliding plane of the reference plate 6.
  • the slope of the guide rails 9, 9 ' causes the pressure to increase when any one of the pouring tubes 2, 2' approaches the pouring orifice and decreases when it moves away from it, allowing a easy removal of the above-mentioned plate in the standby position 14 away from the tap hole 7.
  • the reserve pouring tube 2 pushes the pouring tube into service 2 '.
  • the device 1 according to the invention makes it possible to replace a pouring tube 2 ′ in a continuous casting installation, without perceptibly interrupting the pouring jet.
  • the used tube 2 ' is loosened and moved away from the pouring zone towards a standby position 14 and the reserve tube 2 is brought simultaneously under the pouring channel.
  • the linear displacement of the two pouring tubes 2, 2 ′ can also be carried out using a device of the threaded rod-nut type.
  • the assembly of the pouring tube consists of a flat connection which has the property of having an excellent seal and of being able to be easily inertized.
  • the supply device is a handling device which makes it possible to supply the reserve tube 2, cast horizontally.
  • the plunging end 17, is introduced into a well 18 of an ingot mold 19 by rotating the pouring tube around an axis substantially horizontal.
  • the tube is made to slide transversely along the opening of the mold well thanks to the two jacks 16, 16 ′ shown in FIG. 4, so as to align the neck of the pouring tube on the pouring orifice.
  • the reference plate 6 is arranged obliquely, so that its slope follows the path of supply of the tubes from their standby position to that of continuous casting.
  • An inclined arrangement of the reference plate 6 aims to facilitate the introduction of the plunging end 17 of the tube because it allows the tube to occupy a higher position than if the plate 6 was arranged horizontally.
  • This tube 6 is therefore less inclined than if it had been introduced into a supply and exchange device conventional comprising a horizontal reference plate 6.
  • An inclined arrangement of the reference plate 6 also makes it possible to reduce the distance between the bottom of the distributor and the mold, without encroaching on the diving height of the tube.
  • the casting operation is started as soon as the pouring tube is moved towards the pouring orifice. Under the thrust of the pusher arm 15, a rim of the attached plate 3 of the tube 2 is applied sealingly against the juxtaposed rim of the shutter plate 3 ".
  • the added plate 3 forms with the shutter plate 3" a united surface sealingly applied against the reference plate 6. It is therefore sufficient to put the pouring tube in place by sliding under the thrust of the jacks 16, 16 '.
  • the feeding of the shutter plate 3 8 is performed on the push of a second pusher arm 15 'rigidly fixed to the rods of the hydraulic cylinders 16,16 double effect.
  • the used tube 2 ' is moved towards the standby position 14 under the thrust of the closure plate 3 ".
  • the used tube 2 ′ is loose and can be easily removed from the supply device and be replaced by a new tube since the pusher arm 15 is retractable.
  • the new pouring tube 2 can be quickly put in place under the pouring channel.
  • the total duration of the operation for replacing a worn tube 2 'with a new tube is therefore very short. It does not exceed ten seconds for experienced operators. In addition, it can be carried out without being hindered by the other pouring lines connected to the same distributor, since it is carried out in the longitudinal direction, in the extension of the trajectory determined by the rails 9, 9 '.
