Definitions
- the invention relates to a device for Control of a stopper of a metallurgical vessel, in particular a tundish of a continuous caster, with a lifting and lowering stopper, which is in a relative to the metallurgical vessel movable support frame is supported, which is detachable can be locked with the metallurgical vessel.
- a device of the type mentioned is for example, EP-A1-439 681.
- This Traverse is in turn with one in a vertical guide connected up and down movable support rod, wherein the vertical guidance of the support rod as roller guidance is trained.
- the well-known training is at Outside of the trough set so that the Movability relative to the metallurgical vessel or to the distribution channel only within the guide on the Outside of the distribution channel or the metallurgical Vessel is given.
- GB-A-1 247 238 is a guide for one Plug became known, in which the plug swung out of a metallurgical vessel can be.
- the stopper is hung on a cart which up on rails on a mast can be driven to remove the stopper from the Lifting vessel. Then the stopper is turned around a fixed axis pivoted to the side, in maintenance work is carried out in this position can.
- the stuffing rod usually at one end with a metal part for attachment to a holding boom and with a cooling channel is equipped after a predetermined number knocked off from bathtub empties, because on the one hand is used up and on the other hand non-destructive Decrease associated with relatively great effort would.
- further are already Swivel mechanisms have been proposed which but also did not prevail.
- the invention now aims to provide a device of the type mentioned at the beginning with which a separation of the plug mechanics from the metallurgical Vessel or the distribution channel of a continuous caster is possible without high operating effort and which makes it possible, for example, to change the distributor to carry out without the having to dismantle the entire plug mechanism.
- the training according to the invention aims to such a renovation of the lining without impairment through the plug mechanism.
- the invention Training essentially characterized by that the support frame for the lifting and lowering plug on an outside of the metallurgical vessel movable portal frame transverse to the stroke direction of the Stopper slidable outside of the metallurgical Vessel is supported.
- the support frame on an outside of the metallurgical vessel movable portal frame is supported or suspended, such portal frame one or more supporting frames for lifting or retractable plugs to accommodate this way the rapid attachment of one or more plug guides to enable a distribution pan.
- the portal frame can either be stationary the casting platform or, for example, with the distribution wagon be mounted on the move, in the case of a stationary Arrangement of the portal frame naturally the metallurgical vessel or the distribution channel in the corresponding Movable or slidably mounted have to be.
- the invention is particularly advantageous Training to the extent that the lifting and lowering plug or the support frame the same transverse to the direction of displacement of the portal frame is guided. With such training can be highly flexible and movable with stationary installation of the running track for the portal trolley be achieved. If the portal frame after Type of a carriage to be moved on a track can, by moving the support frame relative to the portal frame in a simple way, the desired adjustment relative to the metallurgical Vessel or to the distribution channel.
- the releasable locking is advantageous to reduce relative to the metallurgical vessel like this trained that the support frame is formed with a claw is which is trained with a complementary Coupling link on the outside of the metallurgical vessel in the operating position of the Stuffing works together.
- a claw requires only little design effort and that on this way on the distribution channel or on the metallurgical Vessel to be arranged locking member for the Intervention of the claw does not constitute a disability of any kind in brickwork.
- a counter lock for the Removal of the distribution channel or the metallurgical Vessel for the purpose of carrying out brickwork be quite useful.
- the support frame via a common drive, in particular Chain drive, can be raised and lowered relative to the portal frame his.
- FIGS. 3 to 5 schematically show the basic elements of a Device for controlling a stopper 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 distributor trough possible is; 3 in an enlarged scale in a to Fig.1 analog representation of the invention
- Control device a stopper of a metallurgical vessel, wherein the device has a movable portal frame includes; 4 in a representation analogous to FIG Inoperative position of the device according to Figure 3; 5 shows a rear view of the embodiment 3 and 4.
- 1 and 2 with 1 is a metallurgical Vessel, such as a distribution channel, which is mounted on a casting platform 2.
- the Casting platform 2 can be moved, as shown schematically is indicated by wheels 3.
- the distribution pan points out at regular intervals Pouring openings 4, which in the shown in Fig.1 Casting position closed by a stopper 5 are.
- the plug or the plug rod 5 points in known manner a substantially in the longitudinal direction extending channel for cooling on like this is indicated schematically at 6, and is over a Metal part 7 can be fixed to a holding boom 8.
- 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 an up and down movement the plug rod 5 in the sense of the double arrow 11 movable in a conventional manner.
- the support frame 10 for the plug or the plug guide 9 a guide 12 via a corresponding bracket 13 stored, for example via an electromechanical Hoist 14 on the one hand lifting and Lowering the entire support frame 10 also in The meaning of the double arrow 11 can be done 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 is. So it succeeds, like this in particular Fig. 2 shows the entire plug control and the support frame 10 for the plug in one position to bring in which the metallurgical vessel or the distributor trough 1 from the position on the casting platform can be easily lifted off, for example Brick work to be carried out.
- Fig. 1 and 2 is thus the support frame 10 for the plug guide 9 in one on the direction of movement of the stopper as well the plug mechanism in a substantially normal direction movable, the adjustment in the on 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.
- a hand lever 19 is indicated, which a manual actuation of the gallows 8 the Plug guide enables.
- the support frame is 10 for the plug guide 9 or over the holding boom 8 associated plugs 5 in a gantry 21 stored, this gantry car 21 schematically indicated wheels 22 on a running rail 23 is movable and thus essentially along the The longitudinal extent of the distribution channel 1 is displaceable.
- the portal carriage 21 has one of the fixed guides 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 the double arrow 15 transversely to 11 indicated Direction of movement of the plug or Plug guide is slidable.
- Operating position is the support frame 10 on the generally designated by 16 clamping device the claw 17 on a corresponding coupling piece 18 stably fixed on the outside of the distribution channel 1.
- FIG. 5 shows that in the gantry 21 three at 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 are the guides 24 can be seen on the gantry car storage and support for these in turn in general is designated by 14. It can therefore be used in the gantry 21 a plurality of plug guides exactly can be positioned relative to each other, so that when appropriate Positioning the gantry car through a move along the rail 23 relative to one Distribution vessel by simultaneously lowering the Carrier frame precisely adjusted several plug guides are.
- the plug guide 9 or a plug 5 in essentially three normal directions enables so that an exact positioning relative to a metallurgical vessel 1 without further ado is possible.
