    State of the art
    From CH 373869 A a continuous casting plant with a 20 automatic trigger device is known. The system has two independently movable stages 4 and 10. The upper stage 4 can clamp the strand and remove it from a mold. The lower stage 10 can separate the strand and also clamp the strand. A disadvantage of this system is that the construction of the platforms 4 and 10 is complex and requires a large number of clamping members 12 to be controlled. Due to the construction of the stages of the carriage of the stages is heavily loaded by the clamping forces of the clamping members 12 and thus must be very stiff and difficult to be out 30 leads. Since the separator is arranged on the first stage, the continuous casting plant has a large overall length.
    Summary of the Invention 35
    The object of the invention is to overcome the disadvantages of the prior art as well as to provide an apparatus and a method for the continuous casting of a large-sized extruded strand, with which in particular very large and heavy casting strands can be inexpensively produced by means of a simple, robust and uncomplicated system or a simple method to be performed can be generated. 5
    This object is achieved by a device according to claim 1. Advantageous embodiments are the subject of the dependent claims. Specifically, the solution is provided by an apparatus for the continuous casting of a large-sized strand of steel, preferably with a round or square cross section, comprising - a vertically oriented mold for forming an at least partially solidified strand in a vertical
    Casting direction / vertical strand guide with a plurality of strand guide elements for supporting and guiding the strand, wherein the strand guide of the mold is downstream in the casting direction; a gripper carriage with a clamping device, a separating device and a first drive, wherein the clamping device clamp the strand, the separating device separate the strand, and the first drive can move the gripper carriage in a vertical direction in order to pull the strand out of the mold; a holding carriage with a holding device and a second drive, wherein the holding carriage is disposed downstream of the tong carriage in the casting direction, wherein the holding device hold a lower end of the strand, and the second drive can move the holding carriage in the vertical direction; - A discharge for discharging a severed strand. In the vertical continuous caster according to the invention, molten steel is continuously fed in the vertically oriented, i. a vertical or vertical longitudinal axis having, mold shed to an at least partially solid strand.

    Strand is supported and guided in the subsequent vertical Strangftihrung by a few (typically two or three in the casting direction consecutive strand guide rollers, so-called casters, or even a Führungskufe) strand guide elements 5. Unlike conventional
    Continuous casting machines, however, the strand is not pulled out by driven strand guide rollers but by the gripper carriage from the mold. In this case, the solidified strand or nearly solidified strand is clamped by the clamp truck with a clamping device and pulled out in the casting direction with the casting speed from the mold. The advantage of this is that the internal quality of the solidified or almost solidified strand is not adversely affected by the terminals. Moreover, the gripper carriage is moved by a first drive associated with the gripper carriage, which is supported on a roadway arranged outside the strand guide. Thus, the pressure acting on the strand pressure can be significantly reduced, which has a favorable effect on the inner quality of the strand. After the strand 20 has been further extended, the strand is supported by a holding carriage having a holding device and a second drive. Since the holding carriage supports the lower end face of the strand only in the vertical direction, the lateral surface of the strand is not exposed to any further 25 pressing. Then the holding car is moved with the casting speed in the casting direction, which is generally effected by the weight of the strand. Subsequently, the gripper carriage is moved by the first drive against the casting direction upwards, typically 30 to the gripper carriage has a distance to the holding car, which corresponds to the desired length of the strand. Then, the strand is re-clamped by means of the clamping device of the tong carriage, wherein a separating device on the tong carriage begins with the separation of the strand. During the separation 35, the separator is moved with the strand. Finally, the severed strand is discharged by a discharge device. 4/24 22-03-2012 5Printed: 23-03-2012 ,,, zuizuö341 E014.1 10 2012/50094
    In order to cool the strand quickly, it is advantageous if the strand guide comprises a plurality of cooling nozzles for cooling the strand. 5 A simple one. Embodiment is that the system has a common lane on which the holding carriage and the clamp truck are movable. For good accessibility, the roadway is preferably arranged outside the strand guide. 10. According to a simple embodiment, the roadway is designed as a, preferably with an internal cooling listed, drive rod or a guide column. Of course, those skilled in the art also other equivalent lanes be-15 known, for example, a threaded spindle, a ball screw, a rope or chain drive or a hydraulic cylinder.
    According to a further embodiment, the clamping device 20 is designed as a pair of pliers, which by a clamping drive from an unclamped, i. open, position in a clamped position and vice versa can be brought.
    According to a simple embodiment, the clamping drive 25 is designed as a fluid-loaded cylinder, such as a hydraulic or pneumatic cylinder.
    In a simple embodiment, the Ausfördereinrich-device is designed as a Ausfahrwagen comprising a Aufnahmeein 30 unit for receiving the strand and a third drive for moving the Ausfahrwagens, preferably in the horizontal direction.
    A simple replacement of the drives is possible if the first drive and the second drive have at least one, preferably a plurality, identical drive module. As a result, the numbers of individual drive modules can be increased and their prices are reduced. In addition, 5/24/2012 6Printed: 23-03-2012 ζυΐζυο341 E014.1 10 2012/50094 drive forces can be easily achieved by using multiple drive modules.
    According to an advantageous embodiment, the Halteein-5 direction on a retaining lug for supporting the strand in the vertical direction. As a result, the strand can be supported in the vertical direction without a pressure being applied to the lateral surface of the strand. In an embodiment analogous thereto, the receiving unit is designed as a retaining lug for supporting a severed strand in the vertical direction.
    In order to ensure a relative distance between the holding device and the severed strand during the outfeed of the strand, it is advantageous if the outward carriage has a lifting drive for lifting and lowering in the vertical direction of a severed strand. Preferably, the device has a tilting drive for tilting the severed strand. 20
    The object of the invention is also solved by the subject matter of claim 10. Advantageous developments are the subject of the dependent claims. Specifically, the solution is carried out by a process for the continuous casting of a large-sized strand, preferably made of steel with a round cross section with a diameter > 500 mm or a square cross-section with one side length > 500 mm, by means of a device according to one of the preceding claims, comprising a vertically oriented mold, a vertical strand guide, a gripper carriage and a holding car, comprising the following process steps: - continuously casting a molten steel to an at least 35 teilerstarrten strand in the mold; Clamping and withdrawing the strand from the mold by means of the clamp carriage, the strand being clamped and closed in a vertical casting direction is pulled out of the mold at a casting speed; - Supporting the continuously produced strand in the vertical direction by the holding car; 5 - dissolving the clamp of the clamp car from the strand; - Procedure of the clamp car against the casting direction; - Clamping and extracting the strand from the mold by means of the clamp carriage; - Separating the strand by a separator which is moved 10 during the separation with the strand; and - discharging the severed strand.
    In order to reliably prevent the continuously produced strand from falling, the holding carriage is typically moved counter to the casting direction at the start until the holding carriage supports the strand; Subsequently, the holding carriage is moved in the casting direction with casting speed, so that the holding the strand constantly supported. 20 A rapid discharge of the severed strand is achieved when the separated strand taken during removal by a Ausfahrwagen, the holding car is lowered relative to the severed strand or the severed strand is raised relative to the support car, the separated-te strand te from the vertical position tilted in the horizontal direction, and then extended in a horizontal direction.
    When separating, it is advantageous if the separating device 30 is moved synchronously with the gripper carriage. This can be realized in a particularly simple manner if the separating device is arranged on the gripper carriage and is moved therewith. A particularly simple device without a conventional oscillation device can be achieved when the extraction of the strand from the mold takes place in an oscillating manner, wherein the oscillation cycle comprises a plurality of phases, and the oscillation cycle comprises a plurality of phases
    Strand in a phase with a first pull-out speed. vi and in another phase with a second pull-out speed V2, where Vi > v2. As illustrated above, the different pull-out speeds are realized by the gripper carriage, wherein in particular v2 = 0 but v2 can also have negative values.
    In order to increase the energy efficiency in continuous casting, it is advantageous to convert the potential energy of the strand by at least one drive, which is assigned to the Ziegenwagen or the holding car, into electrical energy or hydraulic energy. In electric drive technology dies.als referred to as feedback; in hydraulic drive technology, this can e.g. by a secondary controlled hydraulic motor (see for example http://www.hawe.de/sl/fluid-iexicon/s/sekundaerregelung-von-hydromotoren).

    Downstream of the gripper carriage 6 in the casting direction 3 is the holding carriage 8, which serves to lower the lower end of the strand 2 in the casting direction 3, i. vertical direction, shore. For this purpose, the holding vehicle has a holding device 9 designed as a holding nose or holding anvil. The holding carriage 8 is designed to be movable via a second drive not shown here, in the illustrated case, both carriages 6 and 8 on a roadway 12, as. Rack out-10 leads is traversable. In principle, however, it would also be possible that the gripper carriage 6 and the holding carriage 8 are movable on separate lanes.
    Finally, the continuous casting machine 15 according to the invention comprises a discharge device 10 designed as an exit carriage, which has a receiving unit 11 designed as a quiver for a severed strand 2 ', and a third drive not shown here for horizontal movement of the trolley in the removal plane 14. The quiver 20 in turn has a retaining lug, so that the severed strand 2 'rests on the retaining lug by its own weight.
    Overall, the continuous casting plant is very compact and has an overall height of only 27.8 m between the casting platform 13 and the lowest level of the bottom 15, which is 8.5 m lower than the bottom of the casting hall. The metallurgical length of the plant is 19.5 m. 30 The process steps in the 'continuous casting operation of a round steel strand with 0 800 mm are shown in the subfigures 2a ... 2j.
    In FIG. 2 a, molten steel is continuously poured into a divisional strand 2 in the mold 1, which is drawn out of the mold 1 in the casting direction 3. In this case, the lateral surface of the strand 2 by a pair of pliers carriage clamped and the tongs carriage 6 with the casting speed in the clamped 11:24 22-03-2012 12Printed: 23-03-2012., 'Ζυιζυο341 E014.1 10 2012/50094 6 Casting 3 moves down.
    In Fig 2b it is shown how the lower end face of the strand 5 2 is supported by the holding carriage 8 in the casting direction. Since to the holding trolley against the casting direction 3 is moved vertically upwards.
    In Fig. 2c, another phase of the casting operation is shown. After the weight of the strand 2 has been taken up by the retaining device 9 designed as a holder, the clamp of the clamp carriage 6 is released and the clamp carriage 6 is moved upwards against the casting direction 3 until a distance between the clamp carriage 6 and the lower end 15 of the Strangs 2 is set, which corresponds to the desired length of a strand 2 'to be separated. Meanwhile, the strand 2 continues to be pulled out at casting speed.
    In Fig 2d, the gripper carriage 6 is again clamped to the strand 2 20 and with the separation of the strand 2 by means of
    Separator 7 started. Since the separation of the strand 2 takes a considerable amount of time, the gripper carriage 6 with the separator 7 and the holding carriage 8 are moved synchronously. 25
    In FIG. 2e, the discharge device 10, which is designed as an exit carriage, travels in the horizontal direction on the roadway 12 of the removal plane 14 to the strand 2. The Ausförderwagen has a retaining lug 11 to receive the separated-30 th strand 2 '.
    In FIG. 2f, the extension carriage 10 has received the completely severed strand 2 'by means of the retaining lug 11. The Ausfahrwagen has a lifting drive for lifting the strand 2 '35, so that the strand section 2' is lifted from the retaining lug 9 of the trolley 8. This would be possible in an embodiment not shown but also by the vertical lowering of the trolley 8. 12/24 22-03-2012 13 1Printed; 23-03-2012 ^ '' ZUiZUb34 E014.1 10 2012/50094
    In FIG. 2g, the severed strand 2 'is conveyed out by means of the trolley 10 on the roadway 12. In this case, the Ausfahrwagen 10 is moved by means of a third An-5 drive, not shown in the horizontal direction. Here it would be possible for the strand 2 'to be tilted from the vertical position into a horizontal or inclined position before or during the method. As a result, the strand could be passed directly to a roller table, not shown. 10
    Finally, in FIG. 2h, analogously to FIG. 2b, the holding carriage 8 is again moved counter to the casting direction 3 in order to support the strand 2. FIGS. 2i and 2j correspond to FIGS. 2c and 2d. 15 The process steps when casting the continuous casting plant according to the invention are shown in the subfigures 3a... 3j.
    FIG. 3 a shows how a cold strand 16 terminates the outlet-side end of the mold 1 in a fluid-tight manner. In order to prevent falling of the cold leg 16, the holding car 8 can additionally be used to support the lower end side of the cold leg. The cold leg 16 is clamped by the pliers of. Zangenwagens 6 and pulled out after casting the continuous casting machine in the casting direction 3 from the Ko-25 kille 1. In this process, molten steel is continuously poured into the mold 1 via a SEN, so that the level of the melt in the mold - the so-called meniscus - is kept approximately constant. FIG. 3b shows how the cold strand 16 and the forming strand 2, which is sealed with the cold strand, are pulled further out of the mold 1. In this case, the holding carriage 8 is moved counter to the casting direction vertically upwards, so that the dummy bar 16 is supported on the retaining lug of Haltwa-35 gene.
    In Fig. 3c, the clamping of the pliers of the pincer carriage 6 has been solved and the gripper carriage opposite to the casting direction 3 after 13/24 -03-2012 14Printed: 23-03-2012 * .. * ζυιζυο341 E014.1 10 2012/50094 proceed above. The pliers cheeks were positioned so that the cutting nozzles of the separator 7 come to lie slightly above the joint plane between the dummy bar 16 and the strand 2. 5
    In FIG. 3d, the cold strand 16 is then separated from the strand 2 by the separating device 7 during the continuous casting operation. In any event, the clamping between the forceps 6a of the tong carriage 6 and the strand 2 is restored before severing the strand 10, but typically already at the beginning of the separation.
    FIG. 3 e shows how the outfeed device 10, which is designed as an exit carriage, is moved on the roadway 12 to the cold strand 15 16.
    In FIG. 3f, the cold strand 16 has been separated from the strand 2 and the cold strand 16 has been received by the extension carriage 10. Subsequently, the cold strand is raised by the Ausfahrwagens, 20 or as shown, the holding carriage 8 moved down so that a distance between the retaining lug 9 of the trolley 8 and the lower end face of the dummy bar 16 sets. 25 in FIG. 3g, the severed cold strand 16 is conveyed out, wherein the outward carriage 10 is moved in the horizontal direction on the roadway 12. After the cold strand 16 has been discharged from the strand guide, it can be taken over by a cold strand manipulation device, for example an elevator system or from a hall crane, so that the outfeed carriage is available for the outfeed of strands 2 '.
    Finally, in FIG. 3h, the holding carriage 8 is set against the strand 2 35, so that the lower end face of the strand is supported on the retaining lug 9. 14/24 22-03-2012 15 201206341

    Design details of the continuous casting machine of Figure 1 are shown below:
    In Fig 4a, an elevation of a tong carriage 6 is shown.
    In the upper part of the car there is a pair of pliers 6a, which can be actuated by a clamping drive 6c, which is designed as a hydraulic cylinder. In the lower part of the car is the separator 7, which is designed as a flame cutting machine. The car is supported on two lanes 12, which are connected on both sides of the car with the hall structure. On the lanes 12 is ever a 15 rack 18 on which the three superposed pinion 19 of the drives can move the carriage 6.
    The drive of the clamp carriage 6 can be seen better in FIG. 4b. About three identical drive modules 6b per side 20 having an electric motor, a drive shaft and a pinion 19, which rolls on the rack 18, the tong carriage 6 along the lane 12 is moved. To guide the clamp carriage 6, this has two guide wheels 17 in the upper and in the lower region of the carriage, which are supported on the roadway 12 designed as a support column.
    The clamping device 6a designed as a forceps is shown in more detail in FIG. 4c. The strand 2 can be clamped by the two pivotally connected pliers arms, wherein the actuation is effected by a hydraulic cylinder 6c. In addition, in this illustration, the guide column 12, which is formed of three adjacent carriers, shown. The leftmost box girder is the support for the rack 18 in which the pinions 19 of the drives 6b engage. The rightmost carrier only serves to support the guide wheels 17. 35 16Printed: 23-03-2012 ζυιζυο341 E014.1 10 2012/50094
    The separator 7 designed as a flame cutting machine is shown in more detail in FIG. 4d. The flame cutting machine has a setting and supply mechanism 7a for supplying the lances 7b, wherein the lances are adjustable to the strand 2 5 (see arrows indicating the possibilities of movement). In order to protect the racks 18, the pinions 19 and the drives 6b from slag, three inner sides of the clamp carriage 6 have protective shields 7c in the area of the flame cutting machine 7. 10
    An elevational view of the trolley 8 is shown in Fig 5a. The drive of the holding carriage 8 is carried out substantially identical to the drive of the clamp carriage 6 and need not be further explained; however, the drives of the trailer 8 are referred to as second drives 8a in order to emphasize that both carriages 6, 8 can be moved independently of one another. Instead of the clamping device, the holding carriage on a holding device 9, which can support the strand 2 in the vertical direction as a retaining lug. Since the strand has a considerable potential energy, the drives 6b, 8a of the forceps and the holding car 6,8 are designed as so-called 4-quadrant drives, so that this electrical energy can be fed back into a network. 25
    FIG. 6 shows an illustration of the holding carriage 8, from which the drive situation can be clearly seen, similar to FIG. 4d. The discharge device 10 designed as an exit carriage is shown in FIGS. 7a and 7b. By means of the carriage 10, the separated strand 2 'can be picked up, raised by the retaining lug formed receiving unit 11 of the Ausfahrwagens 10, tilted from the vertical to the horizontal position and 35 are finally extended. For clarity, the third drives were not shown. 16/24 22403-2012
