Definitions
- the invention relates to strand guide rollers of a strand guide device for guiding a cast strand, for. B. a slab, after leaving a continuous casting mold.
- Prior art strand guide rollers are also single or multiple split strand guide rollers, as e.g. in US Pat. No. 5,279,535.
- Such a strand guide roller comprises a plurality of axially adjacent sub-rollers, each sub-roller has two roller pins at its two ends.
- the two opposing roller journals of two juxtaposed sub-rollers are each mounted in their own axial bearings, which are typically combined in a split center bearing.
- such a center bearing may additionally have a curved tooth coupling between the two opposing roller pins for transmitting a torque between the two adjacent partial rollers.
- Such split center bearings in the form of two separate axially adjacent bearings with optionally interposed Bogenzahnkupplung are disadvantageously quite wide and therefore form a particularly wide storage window in which the strand to be led or supported can not be supported by the sub-rollers.
- such center bearings are quite expensive due to the majority of their parts.
- the present invention seeks to provide an at least easily divided strand guide roller with improved strand guidance.
- This object is solved by the subject matter of patent claim 1.
- This article is characterized in that between the second part of the role and the roller journal of the first part of a roller role connector is formed for plugging the first and the second part of the role with each other and that the center bearing is designed as undivided single bearing.
- the center bearing serves to support the first part of the role by receiving their roller pin.
- the center bearing must be designed only as an undivided single bearing.
- the second part of the role with the first part of the role is connected such that the second part of the role can be supported on the first part of the role. Due to the connector with the first part of the second roller role does not require its own bearing; Rather, the second part of the role is stored on the connector in or on the first part of the role.
- the customary in the art second bearing within the center bearing for the second part of the role can therefore account for the same as the curved tooth coupling in the inventive design of the strand guide roller.
- the center bearing therefore only has a single bearing, the width of the center bearing and thus the width of the window between the two adjacent sub-rollers over the prior art can be reduced.
- This has the advantage that the bearing surface is increased for the slab, whereby the Füh- tion and support function of the strand guide device for the slab is improved.
- center bearing formed as a single bearing preferably in the form of a standard bearing, is less expensive than a split center bearing.
- the sub-roles in the inventive design of the strand guide roller are easy to assemble and disassemble.
- the plug connection can be realized by inserting a roller journal of a partial roller into a recess of the adjacent partial roller.
- the connector is then not in the form of an additional component, e.g. a separate coupling formed; this has the advantage that the cost of such a component omitted.
- An embodiment of the cross section of the roller journal and of the cross section of the associated recess, each in the form of a polygonal shaft profile, has the advantage that the two adjacent partial rollers are then connected to one another in a positive and non-positive manner for transmitting a torque.
- the transmission of torque between the sub-rollers is particularly interesting when not driven by a motor part rollers.
- the positive and non-positive connector has the advantage that even if only a part of the roll is rotated by contact with the transported slab, the adjacent part rolls are rotated, even if they themselves have no contact with the slab. This has the advantage that excessive heating and thus distortion and jamming of this partial role is avoided.
- the recess is subjected to very high loads, in particular in the case of polygonal-shaped formations for transmitting a torque, and can therefore wear out quickly, as the corners and flanks are increasingly rounded during operation; a transmission of torque would then only insufficient or not possible.
- the recess is not provided directly in the end faces of one of the sub-rollers, but instead is defined and limited by an annular insert element, which is inserted into a bore in the end face of a sub-roll.
- the insert element has the advantage that it can be exchanged cost-effectively at any time as a wearing part.
- cooling channels in the sub-rollers has the advantage that the sub-rollers do not overheat; the extent of possible cooling can be influenced by the number of cooling channels provided.
- a cooling passage has an inner tube whose outer diameter is smaller than the inner diameter of the cooling passage, the inner tube represents a first cooling passage and the space between the inner tube and the cooling passage represents a second cooling passage. In the first and the second cooling line, a coolant can be guided in opposite directions.
- the invention relates to driven and non-driven strand guide rollers alike.
- FIG. 1 shows a first embodiment of the strand guide roller according to the invention.
- FIG. 2 shows a cross section through the strand guide roller according to the first embodiment
- 3 shows a second embodiment of the strand guide roller according to the invention
- Fig. 5 is a detail view of the strand guide roller according to the second
- FIG. 1 shows a first exemplary embodiment of the strand guide roller 100 according to the invention.
- the strand guide roller is here divided by way of example in duplicate and accordingly comprises a total of three partial rollers 110-1, 110-2, 110-3.
- the two-fold division is represented by two center bearings 120-1, 120-2, which are arranged in the transition regions between in each case two of the said partial rollers.
- the center bearings ensure an axial arrangement of the sub-rollers side by side.
- the first partial roller 110-1 is mounted in the first center bearing 120-1 and the outer bearing 120-0, in which these two bearings each receive a roller journal 112-1, 112-0 of the first partial roller 110-1.
- the second partial roller 110-2 is not supported directly in the center bearing 120-1. Instead, it has a recess 116-2 on its front side 114-2 facing the first partial roller 110-1.
- the recess 116-2 is formed or contoured in accordance with the cross section of the roller journal 112-1 or the extension of the roller journal.
- the first and the second partial rollers 110-1, 110-2 are then connected in such a way that the roller journal 112-1 is inserted in an accurately fitting manner into the correspondingly shaped recess 116-2.
- the roller journal 112-1 and the recess 116-2 form insofar a plug connection for the two partial rollers.
- a second bearing for receiving and supporting the second part of the roll 110-2 is therefore unnecessary in the inventive design of the strand guide roller. Therefore, the center bearing 120-1, 120-2 may be formed as an undivided single bearing, which has the advantage of a significantly narrower window width B compared to a split center bearing.
- the second part of the roll 110-2 has at its first part of the roll facing end face 114-2 no recess, but also a roller pin, which has a smaller diameter than the roller journal 112-1 of the first part of the roller 110-1.
- the plug-in connection could then be realized in that this roller journal of the second partial roller is inserted into a recess in the end face of the roller journal 112-1 of the first partial roller.
- the formation of the connector in the form of a separate component between the two sub-rollers 110-1 and 110-2 outside of the center bearing 120-1.
- the connector may be formed in the strand guide roller according to the invention as a clutch for transmitting a torque between the two adjacent sub-rollers or only as a pivot bearing, which does not allow transmission of torque.
- a design as coupling is also useful in the case of a strand guide roller 110 which is not driven externally by a drive device 150 (see FIG. 3).
- a coupling function may be included the embodiment described above, in which a roller pin is inserted in a recess, can be realized simply by not forming the recess in a circular shape but, for example, in the form of a polygonal shaft profile. An example of this is shown in FIG.
- Figure 3 shows a second embodiment of the strand guide roller 100 according to the invention, which differs from the first embodiment only in the configuration of the connector.
- this embodiment of the connector is shown enlarged; It will therefore be described below with reference to Figure 4 in more detail.
- the recess 116-2 in the second partial roller 110-2 and the roller journal 112-1 in the first partial roller 110-1 are not precisely matched to one another, but rather the cross-section of the roller journal 112-1 or 112-1. whose extension is much smaller than the cross section of the recess 116-2.
- the recess 116-2 - even if the connector is realized as a coupling - for simplicity, preferably not limited polygonal wave, but realized as a simple bore.
- a preferably annular insert member 130 is inserted, which is locked by means of clamping pins 132 against rotation in the bore.
- the insert element 130 now has in turn a recess 134, which is adapted precisely to the cross section of the roller journal 112-1 or its extension 113-1. If this recess 134 is circular, no torque between the two sub-rollers 110-1 and 110-2 can be transmitted. However, if it is polygon-shaped and in particular, for example, square, as shown in Figure 5, it can also transmit a torque in cooperation with the correspondingly shaped cross section of the roller journal 112-1 or 113-1.
- FIGS. 1 to 5 show a central axial cooling channel in the strand guide roller 100, which is also continuous across partial rollers.
- an inner tube 142 whose outer diameter is smaller than the inner diameter of the cooling channel 140, can be inserted into this cooling channel 140.
- cooling medium in one direction in the inner tube 142 and To transport the cooling medium in the space between the inner tube and the wall of the cooling channel 140, for example in the opposite direction.
- a larger required cooling capacity and a plurality of cooling channels can be formed axially parallel, for example in the form of a turret role in the individual sub-roles.
- These cooling channels in the individual sub-rollers can then optionally be sealed against each other or not.
