Definitions
- the invention relates to a device for controlling a stopper of a metallurgical vessel, in particular a distribution channel of a continuous casting installation, with a liftable and lowerable stopper, which is supported in a support frame which is movable relative to the metallurgical vessel and which can be releasably locked to the metallurgical vessel is.
- a device of the type mentioned in the introduction can be found, for example, in EP-Al-439 681.
- the stopper in order to adjust a stopper of a distributor channel in a controllable manner, the stopper is connected to a crossbar arranged above the distributor channel or the metallurgical vessel.
- This traverse is in turn connected to a support rod that can be moved up and down in a vertical guide, the vertical guide of the support rod being designed as a roller guide.
- the known design is fixed on the outside of the distribution channel, so that the mobility relative to the metallurgical vessel or to the distribution channel is only given within the guide on the outside of the distribution channel or the metallurgical vessel.
- This fixed and rigid connection between the plug mechanism and the distributor trough means that the control or the stuffing rods also during a refurbishment of the lining Distribution troughs are usually not removed, since the fixed attachment to the distribution trough requires too extensive and complicated removal work.
- the stuffing rod which is usually equipped at one end with a metal part for attachment to a holding boom and with a channel used for cooling, is knocked off after a predetermined number of trough empties, since on the one hand it is used up and on the other hand it is used for non-destructive removal would be connected with a relatively large outlay.
- swivel mechanisms have also already been proposed, but these have also not become established.
- the invention now aims to provide a device of the type mentioned at the outset with which the plug mechanism can be separated from the metallurgical vessel or the distributor trough of a continuous casting installation without high operating effort and which makes it possible, for example, to change the distributor, without having to dismantle the entire plug mechanism for this purpose.
- the design according to the invention aims to enable such a brickwork replacement without being affected by the plug mechanism.
- the design according to the invention is essentially characterized in that the support frame for the liftable and lowerable stopper is slidably supported outside the metallurgical vessel transversely to the stroke direction of the stopper.
- the support frame can now be releasably locked to the metallurgical vessel, on the one hand creates the possibility of unlocking the frame from the metallurgical vessel or distributor for a distributor change and, on the other hand, ensures an exact and relatively tolerance-free operating mode in the working position .
- the design according to the invention is advantageously made such that the supporting frame is supported or suspended from a portal frame which can be moved outside the metallurgical vessel.
- a portal frame can accommodate one or more support frames for lifting or lowering plugs in order in this way to enable the rapid attachment of one or more plug guides to a distribution trough.
- the portal frame can be mounted either stationary on the casting platform or, for example, traveling with the distribution trolley, whereby in the case of a stationary arrangement of the portal frame, the metallurgical vessel or the distribution channel must naturally be movable or displaceably mounted in a corresponding manner.
- the training according to the invention is further developed in such a way that the plug which can be raised and lowered or the supporting frame thereof is guided so as to be displaceable transversely to the direction of displacement of the portal frame.
- a high degree of flexibility and displaceability can be achieved when the running rail is laid stationary for the portal trolley. If the portal frame can be moved on a running rail in the manner of a carriage, the desired adjustment can be achieved in a simple manner by displacing the supporting frame relative to the portal frame relative to the metallurgical vessel or to the distribution channel.
- the support frame is advantageously guided so that it can be raised and lowered.
- the releasable locking relative to the metallurgical vessel is advantageously designed such that the support frame is designed with a coupling member, in particular a claw. which cooperates with a complementary coupling member on the outside of the metallurgical vessel in the operating position of the stopper.
- a coupling member in particular a claw.
- Such a claw requires little design effort and the locking member to be arranged in this way on the distribution channel or on the metallurgical vessel for the engagement of the claw does not constitute a hindrance of any kind in masonry work.
- a counter-locking mechanism can be used to remove the Distribution channel or the metallurgical vessel may be useful for the purpose of carrying out brickwork.
- the design is such that a plurality of supporting frames, in particular three supporting frames, for lifting and lowering plugs are supported on the movable portal frame, the constructional effort being able to be kept relatively low by the common portal frame .
- the supporting frames can be raised and lowered relative to the portal frame by means of a common drive, in particular a chain drive.
- FIG. 1 shows a view of a first embodiment of a device according to the invention for controlling a stopper of a metallurgical vessel in the operating or casting position
- 2 shows, in a representation similar to FIG. 1, the embodiment according to FIG. 1 in the inoperative position, in which manipulation of the metallurgical vessel or the distributor trough is possible
- 3 shows, on an enlarged scale, in a representation analogous to FIG. 1, a modified embodiment of a device according to the invention for controlling a stopper of a metallurgical vessel, the device comprising a movable portal frame
- 4 shows, in a representation analogous to FIG. 2, the inoperative position of the device according to FIG. 3
- FIG. 5 shows a rear view of the embodiment according to FIGS. 3 and 4.
- 1 and 2, 1 denotes a metallurgical vessel, such as a distribution channel, which is mounted on a casting platform 2.
- the casting platform 2 can be moved, as is indicated schematically by wheels 3.
- the distributor trough has pouring openings 4 at regular intervals, which are closed by a stopper 5 in the pouring position shown in FIG.
- the stopper or stopper rod 5 has, in a known manner, an essentially longitudinal channel for cooling, as indicated schematically by 6, and can be fixed to a holding boom 8 via a metal part 7.
- This holding boom 8 is part of a stopper guide, generally designated 9, which is mounted in a support frame designated 10.
- the stopper guide 9 with the holding gallows 8 can be moved in a manner known per se for an upward and downward movement of the stopper rod 5 in the sense of the double arrow 11.
- the support frame 10 for the stopper or stopper guide 9 is supported on a guide 12 by means of a corresponding holder 13, with an elevating and lowering of the entire support frame 10 can also take place in the sense of the double arrow 11 and in addition the Entire support or the hoist 14 can be moved along the guide 12 in the sense of the double arrow 15.
- the entire stopper control and the support frame 10 for the stopper can be brought into a position in which the metallurgical vessel or the distributor trough 1 can easily be moved from the position on the casting platform can be lifted off, for example to carry out brickwork.
- the support frame 10 for the stopper guide 9 can thus be moved in a direction which is essentially normal to the direction of movement of the stopper and the stopper mechanism, with the adjustment in the direction of movement as determined by the Double arrow 15 is indicated, normal direction, in the sense of the longitudinal direction of the distributor trough 1, is carried out by adjusting the distributor trough 1 on the casting platform.
- the supporting frame is designed with a clamping device, generally designated 16, the clamping device comprising a claw 17 which has a correspondingly complementary coupling member 18 on the outside of the metallurgical Vessel interacts to ensure correct and stable positioning of the stopper guide relative to the metallurgical vessel during operation. It is immediately apparent that this mutual coupling can be easily released.
- a hand lever 19 is indicated, which enables manual actuation of the gallows 8 of the stopper guide.
- a metallurgical vessel or a distribution trough 1 is arranged essentially stationary on a casting platform, again designated 2, and the casting or operating position is again shown in FIG. 3, while the position of the stopper guide or the support frame is shown in FIG the same is shown, in which a simple removal of the distribution channel 1 is possible without hindrance.
- the opening 4 at the distribution channel 1 opens into a mold 20.
- the support frame 10 for the plug guide 9 or the plug 5 connected thereto via the holding gallows 8 is mounted in a portal carriage 21, this portal carriage 21 being movable on a running rail 23 by means of schematically indicated wheels 22 and thus essentially longitudinally the longitudinal extent of the distribution channel 1 is displaceable.
- the portal trolley 21 has a guide 24 corresponding to the fixed guide 12 of the previous embodiment, along which, in turn, the lifting frame 10 in the sense of the double arrow 15 transversely to the direction of movement of the stopper indicated by 11 via a hoist or a support 14 or the plug guide is displaceable.
- the support frame 10 is fixed in a stable manner by means of the clamping device, generally designated 16, via the claw 17 on a corresponding coupling piece 18 on the outside of the distributor channel 1.
- a guide 25 indicated in the upper area of the portal carriage 21 is also shown. Timing chains for the Movement of the support frame 10 in the portal frame and the lifting and lowering of the plug guide are indicated by 26.
- FIG. 5 From the rear view according to Figure 5 it can be seen that in the portal trolley 21 three ge on a common support frame 10 mounted plug guides 9 are arranged, the support frame 10 via a schematically indicated lifting and lowering drive 27 can be raised and lowered. Furthermore, the guides 24 on the gantry car can be seen, the position or the support on this in turn being generally designated with 14 be. A plurality of plug guides can thus be positioned exactly in relation to one another in the portal carriage 21, so that with appropriate positioning of the portal carriage by a method along the rail 23 relatively z a distributor vessel by a simultaneous lowering of the supporting frame, several plug guides are precisely adjusted.
