Definitions
- the invention relates to a device for control a stopper of a metallurgical vessel, in particular a tundish of a continuous caster, with a lifting and lowerable stopper, which is in a relative to the metallurgical Vessel movable support frame is supported, which is releasably lockable with the metallurgical vessel.
- a device of the type mentioned is, for example can be found in EP-A1-439 681.
- this known device is for the adjustable adjustment of a plug of a distribution channel the plug on one above the distribution channel or connected to the metallurgical vessel traverse. This traverse is in turn with one in a vertical guide connected up and down movable support rod, the Vertical guide of the support rod is designed as a roller guide is.
- the known design is on the outside of the distribution channel set so that the mobility relative to metallurgical vessel or to the distribution channel only inside the guide on the outside of the distribution channel or metallurgical vessel is given.
- GB-A-1 247 238 is a guide for a stopper became known in which the stopper from a metallurgical Vessel can be swung out.
- the stopper is hung on a trolley, which on rails on a mast can be moved upwards to remove the stopper from the Lifting vessel. Then the stopper is fixed around a Axis swiveled to the side, in this position Maintenance work can be carried out.
- the stuffing rod usually at one end with one Metal part for attachment to a holding boom and with is equipped with a channel used for cooling knocked off a predetermined number of tub empties, because on the one hand it is used up and on the other hand one non-destructive acceptance associated with relatively great effort would.
- swivel mechanisms have been proposed, but which is also have not prevailed.
- the invention now aims to provide a device of the beginning to create the kind with which a separation of the Plug mechanics from the metallurgical vessel or the distribution channel a continuous caster without much effort and which makes it possible, for example, a distributor change to make without the entire To have to dismantle the plug mechanism.
- the invention Training aimed at such a lining renewal without being impaired by the plug mechanism.
- the invention Training essentially characterized in that the Support frame for the lifting and lowering plug on an outside of the metallurgical vessel movable portal frame slidable transversely to the stroke direction of the stopper outside the metallurgical vessel is supported.
- the support frame is releasably lockable with the metallurgical vessel.
- the possibility is created for a distributor change the frame from the metallurgical vessel or distributor unlock and on the other hand in the working position an exact and ensure relatively tolerance-free operation.
- the support frame on an outside of the metallurgical Vessel movable gantry frame supported or suspended is such a portal frame one or more Support frame for lifting or lowering plugs to take on in this way the rapid attachment of one or more plug guides to enable a distribution pan.
- the portal frame is either stationary on the casting platform or, for example, mounted to move with the distribution wagon be, in the case of a stationary arrangement of the portal frame naturally the metallurgical vessel or the distribution channel movably or displaceably mounted in a corresponding manner have to be.
- the inventive design is particularly advantageous further developed in that the liftable and lowerable Plug or the supporting frame of the same transverse to the direction of displacement of the portal frame is slidably guided.
- Such training can be highly flexible and movable with stationary installation of the running track for the gantry car can be achieved. If the portal frame according to Art a carriage can be moved on a track, succeeds by moving the support frame relative to Portal frame in a simple way, the desired adjustment relative to the metallurgical vessel or to the distribution channel to make.
- a releasable locking relative to metallurgical vessel designed so that the support frame with a claw is formed, which with a complementary trained coupling member on the outside of the metallurgical Vessel interacts in the operating position of the stopper.
- a claw requires little constructive Effort and that in this way on the distribution channel or locking member to be arranged on the metallurgical vessel for the claw's intervention does not constitute a disability of any kind in brickwork.
- a counter lock of this type for the removal of the distribution channel or the metallurgical vessel for the purpose of making it of brickwork can be very useful.
- the support frame can be common drive, especially chain drive, relative to Portal frames can be raised and lowered.
- FIG. 1 shows a view of a first embodiment a control device according to the invention a plug of a metallurgical vessel in the Basic, Casting position; Fig.2 in a representation similar to Fig.1 1 in the inoperative position, in which a manipulation of the metallurgical vessel or the distribution pan is possible; Fig.3 on an enlarged scale in a similar to Fig.1 Representation of a modified embodiment of an inventive Device for controlling a plug metallurgical vessel, the device being a movable Gantry frame includes; Fig.4 in a to Fig.2 analog representation of the decommissioning of the device according to Figure 3; 5 shows a rear view of the embodiment 3 and 4.
- 1 is a metallurgical vessel, such as for example, a distribution channel, which refers to a casting platform 2 is mounted.
- the casting platform 2 can be movable, as indicated schematically by wheels 3 is.
- the distributor trough has pouring openings at regular intervals 4, which is shown in Fig.1 Casting position are closed by a plug 5.
- the Plug or the plug rod 5 has in a known manner a substantially longitudinal channel for Cooling on, as indicated schematically at 6, and can be fixed to a holding boom 8 via a metal part 7.
- This holding boom 8 is part of a generally designated 9 Plug guide, which in a designated 10 Support frame is stored.
- the plug guide 9 with the holding boom 8 is for up and down movement of the plug rod 5 in the sense of the double arrow 11 in a known per se Way movable.
- the support frame 10 is for the plug or the plug guide 9 on a guide 12 a corresponding bracket 13 is mounted, for example electromechanical hoist 14 lifting one hand and lowering the entire support frame 10 also in The sense of the double arrow 11 can take place and in addition the entire support or the hoist 14 in the sense of the double arrow 15 can be moved along the guide 12. So it works it, as can be seen particularly from FIG entire plug control and the support frame 10 for the Bring the plug into a position in which the metallurgical Vessel or the distribution pan 1 from the position the casting platform can easily be lifted off, for example Brick work to be carried out.
- the Support frame 10 for the plug guide 9 in one on the direction of movement of the plug and the plug mechanism in the essentially normal direction movable the adjustment in the direction of movement as indicated by the double arrow 15 is indicated, normal direction, in the sense of the longitudinal direction the distribution channel 1 by adjusting the distribution channel 1 is made on the casting platform.
- Relative positioning of the plug mechanism to ensure metallurgical vessel 1 in the foundry is the support frame with a generally designated 16 Clamping device formed, the clamping device a Claw 17 includes which with a corresponding complementary trained coupling member 18 on the outside of the metallurgical
- the vessel interacts to operate correct and stable positioning of the plug guide relative to the metallurgical vessel. It is immediate it can be seen that this mutual coupling is easy is solvable.
- a hand lever 19 is indicated, which is a manual Actuation of the gallows 8 of the plug guide enables.
- the support frame 10 for the Stopper guide 9 or that connected to it via the holding boom 8 Stopper 5 stored in a gantry 21, wherein this gantry car 21 via schematically indicated wheels 22 is movable on a running rail 23 and thus in essentially along the longitudinal extent of the distribution channel 1 is movable.
- the portal car 21 has one of the fixed Guide 12 corresponding to the previous embodiment Guide 24, along which in turn over a Hoist or a support 14 of the support frame 10 in the sense of Double arrow 15 transverse to the direction of movement indicated by 11 of the stopper or the stopper guide is.
- the Support frame 10 on the generally designated 16 clamping device via the claw 17 on a corresponding coupling piece 18 stable on the outside of the distribution channel 1 fixed.
- Stopper guide 9 or a stopper 5 in essentially three allows normal directions, so that a exact positioning relative to a metallurgical vessel 1 is easily possible.
