    Chilled, multi-layered strand-guiding roller 5 Field of the art
    The present invention relates to a cooled, multi-layered strand guide roll for guiding a metallic strand in a continuous casting machine and a method for cooling a multi-layered strand guide roll.
    In continuous casting, it is known to guide a metallic strand formed in a mold (for example made of steel) in a strand guide, to support and to cool further. Usually, the supporting and guiding of the partially solidified or solidified strand takes place by strand guiding rollers; In addition, the strand can be cooled by cooled strand guide rollers. Due to the high temperature of the strand and the high ferrostatic pressures 20 in the strand, the strand guide rolls are in any case exposed to high thermal and mechanical stresses.
    Specifically, the invention relates on the one hand a strand guide roller for guiding a metallic strand in a continuous casting machine, comprising - at least a first and a second single role, wherein the first single role rotatably connected to the second single role, the individual roles have a channel for internal cooling and a cooled strand guide role Train 30; - At least three bearing blocks, wherein the outer regions of the strand guide roller and at least a portion between two adjacent individual rollers are rotatably mounted on a bearing block.
    Moreover, the invention relates to a method for cooling a multi-stranded strand guide roller. 28/09/2012 16:27

    Specifically, the invention relates to a method for cooling a multi-layered strand guide roll, comprising: - the at least one first and one second single roll, the first single roll being non-rotatably connected to the second single roll, and the single rolls having a channel for internally cooling the strand guide roll; - At least three bearing blocks, wherein the outer regions of the strand guide roller and the area between the individual rollers are rotatably mounted on a bearing block; 10 - a header for supplying the
    Strand guide roller with cooling water comprising a plurality of consoles and each between two successive consoles at least one coolant tube, wherein an outer console each having a first terminal for internal cooling of the strand guide roller 15 and a second connection for cooling the bearing blocks, and the first connection with the channels of the individual roles and the second connection is fluidly connected to the bearing blocks. 20 State of the art
    Multi-layered, internally cooled strand-guiding rollers are already known from the prior art (see, for example, the publication Strandguide Roller - Preconfigured Products for Precision Applications, Siemens VAI, 2007). One embodiment of a so-called CSR (Compact Split Roller) strand guide roller is composed of a plurality of individual rollers connected to one another in a rotationally fixed manner. In order to reduce the thermal load on the bearings, the bearing blocks are also cooled in one embodiment of a CSR roller. In this case, the underside of each bearing block has two connections for introducing and removing cooling water. Since the strand guide rollers are subject to wear and thus the diameter of the lateral surface of the roller changes, it is necessary to be able to adjust the height position of the strand guide roller. For this purpose, a supplement is enclosed between a crossbar of the strand guide and a bearing block (engl., Shim), whereby the supplement however recesses for the 28/09/2012 16:27 N r 3/3365 P.006 / 027 28.

As a result, the side dishes are very delicate and it is the setting of the altitude complex. How a multi-layered, internally cooled strand guide roller can be made simple, robust and reliable in operation, which is also easy to adjust in height, is not apparent from the prior art.
    Summary of the invention 10
    The object of the invention is to overcome the disadvantages of the prior art and to provide a multi-layered, internally cooled strand guide roller, which is simple, robust and reliable. Furthermore, the 15 roll should be easily and quickly height adjustable.
    Another object is to provide a method for cooling a multi-strand strand guide roll. The first object is achieved by the strand-guiding roller according to claim 1. Advantageous embodiments are the subject of the dependent claims.
    Specifically, the solution is carried out in a strand guide roller of the type mentioned above in that a collecting bar for
    Supply of the strand guide roller is provided with cooling water, which comprises a plurality of consoles and each between two successive consoles at least one coolant pipe for fluidic connection of the consoles. An outer console has at least one first connection for cooling the cooled strand guide roller and at least one second connection for cooling the bearing blocks, wherein the first connection is fluidically connected to the channels of the single rollers and the second connection is via the consoles to the bearing blocks.
    The strand guide roller according to the invention has two separate cooling circuits. The first cooling circuit represents a 28/09/2012 16:28

    Internal cooling of the strand roll composed of individual roles and the second circuit an internal cooling of the bearing blocks safely (the second circuit connects the bearing blocks together and causes a cooling 5 of the camp or the bearing blocks). This has the great advantage that the cooling water quantities for both circuits and thereby also the temperatures of the strand guide roller and the bearings can be set completely independently of each other.
    Thus, the surface temperature of the strand guide roller 10 can be adjusted independently of the temperature of the bearings. This allows a targeted cooling of the strand by the strand guide roller, especially during hot or dry casting, without causing the bearings overheat. Thus, inexpensive bearings, e.g. 15 temperature-sensitive plain bearings, can be used.
    The construction according to the invention has a so-called collecting bar, which is detachably connected to the bearing blocks of the strand guide roller. The header bar 20 is composed of several outer brackets and at least one inner console. Between two successive consoles, at least one coolant tube is provided in each case for the fluidic connection of the brackets. The header bar makes it easy to adjust the 25 height position of the strand guide roller; In addition, the two cooling circuits are supplied with cooling water by the collecting bar.
    In this case, cooling water is introduced into the inner channel of the strand guide roller via a first connection of an outer console 30 of the collecting beam. In addition, cooling water is introduced into the outer console via a second connection. The connection between two consecutive (adjacent) consoles is made by at least one coolant tube. Furthermore, each console is fluid-tightly connected to a bearing block, wherein the bearing block has at least one channel for cooling. At the same end or at the opposite end of the collecting beam, cooling water will be removed from the 28/09/2012 16:28 N r 5/3365 P.008 / 027 28. Sep. 2012 16:25 201222317

    In one embodiment, each outer console has first and second ports. Here, cooling water is introduced on one side in the strand guide roller 10 and on the opposite side of the
    Strand guide roller discharged again. The flow of the bearing blocks is the same. In this embodiment, the supply of the coolant in the two cooling circuits can be done either on the same side or on opposite 15 sides.
    In an alternative embodiment, an outer console has two first terminals and two second terminals. The supply and removal of the cooling water takes place in both 20 cooling circuits on the same side of the manifold. Here, cooling water is introduced at one end into the strand guide roller, then the roller is flowed through in the longitudinal direction, at the opposite end of the strand guide roller, the flow direction is reversed, flows through the roller in the longitudinal direction, and the cooling water discharged at the same end of the strand guide roller. The flow through the bearing blocks is the same. For example, the cooling water is supplied from console to console through a first series of coolant tubes, reversed the flow direction of the cooling water at the last console and finally discharged the cooling water from console to console through a second series of coolant tubes again.
    In an advantageous embodiment, the header bar between two successive consoles comprises two coolant tubes for connecting the consoles. As a result, first, the brackets are secured against each other against rotation; secondly, e.g. the coolant through a coolant pipe in 28/09/2012 16:29

    It is useful if a first connection of a 5 external console via a line and a
    Rotary inlet is connected to a channel of the single role. The pipe can be a pipe or a hose. 10 For a uniform cooling of a bearing block, which is divided by a horizontal plane passing through the axis of rotation of the strand guide roller in a lower part and a top, the lower part has at least two holes which are offset in the casting direction. As a result, thermal stresses of the bearing 15 are prevented. In this embodiment, it does not matter whether the upper part and the lower part are releasably connected to each other, or whether it is a component (so-called monoblock). 20 A bearing in the bearing block is cooled evenly when the
    Upper part has a water channel, which can lead cooling water from a first bore in the lower part to the bearing around in a second bore in the lower part. In addition, the lower part may also have an annular water channel. 25
    A simple, robust and fluid-tight connection between two individual rollers can be achieved if one end of the first single roller has a pin and one end of the second single roller has a recess for receiving the pin 30, and the pin is rotatably connected to the recess.
    In one embodiment, the fluidic connection between a console and a bearing block is accomplished by a plug-in tube. Alternatively, the console can be sealed to the bracket by an O-ring. 28/09/2012 16:29 N / a 7/3365 P. 010/027 28. Sep. 2012 16:26 201222317

    The production of an external console can be greatly simplified if the console, preferably on its underside, comprises an aligned parallel to the casting direction intermediate plate. The intermediate plate has at least 5 a first terminal and at least one second terminal. Thus, cooling water can be introduced from a strand guide segment via a plug pipe and a port into the intermediate plate, whereby the cooling water from the intermediate plate via a seal (eg., An O-ring) is continued to a pipe or a coolant pipe.
    Furthermore, it is expedient if a strand guide segment is releasably connected to a console of the collecting beam, wherein the strand guide segment is the fluidically connected to an outer console by a plug-in tube. Through a
    Plug pipe is a fluidic connection even with a relative displacement between two components (for example, in the height adjustment) ensured. For easy height adjustment of the console relative to a strand guide segment, it is advantageous if a console has a screw for height adjustment of the console relative to the strand guide segment, wherein between the bracket and the strand guide segment an insert is arranged. 25
    The second object of the invention is achieved by a method according to claim 13.
    Specifically, the solution is carried out in a method of the type mentioned 30 in that cooling water is introduced via a first connection of the collecting beam in the strand guide roller, the cooling water flows through the individual roles in succession, and the cooling water via a further first connection of the collecting beam derived from the 35 strand guide roller becomes; and that cooling water is introduced into the header via a second port, the cooling water is sequentially routed to the pedestals, and the pedestals are cooled, and the cooling water is passed through to the header 28/09/2012 16:29

    5 10 15 20 25 30 another second connection is derived from the collecting bar. This solution is advantageous because the two cooling circuits for the internal cooling of the strand guide roller and the cooling of the bearing blocks are separately adjustable.

    or a press fit between a pin 16 and a recess 17 in the individual rollers 2 rotatably connected to each other. In order to be able to withstand the high mechanical loads caused by the symbolically represented steel strand S, the strand guide roll 1 is rotatably mounted both in the outer regions 5 of the roll and in each case in the region 6 between two individual rolls 2a, 2b. In this case, the strand guide roller 1 is supported on the 10 bearing blocks 4 via the bearings (not shown in detail) (for example a ball bearing or a sliding bearing). In order to withstand the high thermal loads, the individual rollers 2a, 2b each have an internal cooling water channel 3. As a result, the surface temperature of the strand guide roller 1 is limited or specifically set; In addition, the strand S is cooled over the 15 lateral surface of the roll 1. In order to prevent overheating of the bearings in the bearing blocks 4 (in particular in a Gießstopp or a slowdown of the casting speed), the lower parts 4a of the bearing blocks 4, each with two holes 14 are executed. The lower part 4a of the bearing block 4 is releasably connected to the upper part 4b. Each bracket 4 is in each case fluid-tightly connected to a console 10, wherein the two outer brackets 10 a, the inner console 10 b and the coolant tubes 11 between each two successive consoles 10, the collecting bar 7 25 form. About the collecting bar 7 is the
    Strand guide roller 1 supplied with cooling water.
    On the one hand, cooling water (in this application, the liquid cooling fluid, which besides H2O may also have other components 30, also referred to as cooling water) via the first port 8 in the outer console 10a shown on the right and from the console 10a via the line 12 in the Coolant channel 3 of the strand guide roller 1 introduced. After the cooling water has flowed through the channels 3 of the two individual rollers 2 35, it is discharged from the strand guide roller 1 via the line 12 to the first terminal 8 in the outer bracket 10 a shown on the left.

On the other hand, cooling water is led to the bearing blocks 4 via the second connection 9 in the sweeter console 10a shown on the right. Here, each console 10a, 10b fluid-tightly connected to a bearing block 4. The connection between two adjacent consoles 10a-10b and 10b-10a takes place via two coolant tubes 11. The heated cooling water is discharged via the second connection 9 in the outer console 10a shown on the left.
    For cooling, the lower parts 4a of the bearing blocks 4 each have two bores 14, which have an offset in the casting direction R. In the case of rollers 1 which are even more highly loaded thermally, the upper parts 4b of the bearing blocks 4 can also have an annular water channel 15, so that the cooling water flows from a first bore 14 in the lower part 4a into the upper part 20b and from the upper part 4b over the water channel arranged concentrically with the pin 16 15 in a second bore 14 in the lower part 4a can flow (see Figure 8). As a result, the bearing block 4 and the bearing is effectively protected against overheating or specifically set a storage temperature. 25
    The first and second terminals 8,9 of the outer brackets 10a of the bus bar 7 can be as shown on the underside of the brackets 10a or also e.g. located on the side of the console. A lateral arrangement is advantageous because the height adjustment bracket 10a of FIG
    Strand guide roll 1 simply inserts 19 (see Figures 2, 3, 5, 6 and 8) can be enclosed without the inserts would affect the tightness of the fluid connection. 35 A second embodiment of an inventive
    Strand guide roller is shown in FIGS. 2 to 8. In contrast to FIG. 1, the strand-guiding roller 1 is formed by three individual rollers 2a... 2c. The two outer areas 28/09/2012 16:30

At the other end of the 20 busbar, the cooling water is discharged in an analogous manner. Cooling water is fed via the second connection 9 in the outer console 10a on the one hand into the lower part 4a of the bearing block 4 and on the other hand via the coolant tubes 11 to the following consoles. 25
    The cooling water guide in an outer console 10a is shown in more detail in FIGS. 7 and 8. As already described, cooling water is introduced via a plug pipe 18 and the first port 8 into the outer bracket 10a 30 and guided from the outer bracket 10a via the line 12 to the strand guide roller 1. In addition, there is a separate cooling water circuit for the cooling of the bearing blocks 4, wherein cooling water is also introduced via a plug pipe 18 and the second port 9 in the outer console 10a 35 and from this one hand, the bearing block 4 cools, which is connected to the outer console 10a, and supplied via the two coolant tubes 11, the inner brackets 10b.
