Description
:
~137~45 The invention relates to a strand guide in a continuous casting plant with rollers or rolls, respectively, having -distributed over their longitudinal extension - a number of bearing pins mounted in bearing housings, which bearing housings are supported by a stationary supporting construction.
In modern continuous casting plants, in particular in casting plants for slabs, the strand is cast with great speed.
Therefore the strand has a thin strand skin immediately upon leaving the mould, which strand skin must be carefully sup-ported by supporting rollers or rolls, respectively, arrangedclosely behind one another. In order to be able to arrange the axes of the supporting rollers particularly closely behind one another to prevent an all too pronounced bulging of the strand skin, supporting rollers having as small a diameter as possible are used. An undue bending of these relatively long, thin rollers is prevented by a number of bearing places distributed over the longitudinal extension of a roller.
The installation of this multiply supported roller into the strand guide is a problem, in particular when individual rollers have to be installed into the strand guide to replace damaged rollers. Hitherto these rollers have been installed into the strand guide according to two different methods.
Either the bearing housing lower parts have been mounted in the strand guide stand, and then the rollers have been in-serted therein and fixed with the bearing lids, or the rollers have been inserted in the bearing housings at first and then installed in the strand guide together with the bearing housings, wherein the bearing housings have been fixed on the strand guide stand. Since, however, together with the rollers in most cases also the bearings are worn and have to be exchanged, the ;:
, -10;~7~f ~5 latter described installation ~ethod has been preferred, since with thls method the period of standstill of the continuous casting plant necessary for exchanging the rollers and bearings can be kept much shorter than with the first described method.
Difficulties arise, however, insofar as it is necessary to get all the bearing housings of a roller rotating freely around the roller axis into the position necessary for an installation.
Thus, shortly before inserting the roller into the strand guide, it is necessary to rotate the bearing housings into a position, in which the bearing faces of the bearing housings are directed towards the bearing places in the strand guide stand and maintain them in this position during the installation. This procedure .
is especially disadvantageous when very wide rollers are used having a correspondingly great number of intermediate bearings, as well as when rollers are used that have to be inserted into the roller path supporting the upper side of the strand. In order to get to the inwardly arranged bearing places, it used to be necessary to get the two roller paths, supporting the strand apart, i.e. to take the strand guidestand apart.
The invention aims at preventing these disadvantages and difficulties and has as its object to create a strand guide of the above defined kind, in which all the bearing housings of a roller or roll, respectively, can be brought into and kept in the position necessary for an installation by means of the two bear-ing housings arranged at the ends of the roller or roll, respect-ively, so that manipulations at the inwardly arranged bearing housings, which are difficult to get at, are no longer necessary during the installation of the roller or roll, respectively.
According to the invention a roller or roll assembly is used in a continuous casting plant strand guide arranged in a stationary supporting construction and comprises a roller or roll having a number of bearing pins distributed over its longitudinal .: :

extension; bearing housings provided to accommodate said bearing pins, the bearing housings being supported on the stationary ~ supporting construction, and connecting means extending parallel - to the axis of said roller or roll and interconnecting said bear-ing housings to secure said bearing housings against rotation relative to one another around the axis of said roller or roll ; . . .
independent of the arrangement of the assembly on the supporting construction.
Preferably the bearing housings are interconnected by rigid pipe conduits acting in addition for supplying the coolant and/or lubricant. Thus, when cooled or lubricated rollers are ~, .
used, respectively, one needs no longer connect and disconnent the coolant or lubricant conduits, respectively, with each in-dividual bearing housing of a roller during installation and re-moval thereof. The roller and its bearing housings and coolant or lubricant conduits, respectively, constitute an integral con-struction unit kept on store in assembled condition and installed in the strand guide stand when needed, with a great time advan-tage relative to other constructions.
One preferred embodiment is especially well suited for supplying the bearing places of a roller with lubricant. A sep- -arate pipe conduit is connected to each bearing housing, the pipe conduits of the bearing housings inwardly arranged along the lon-gitudinal extension of the roller being quided towards the out-side through bores of the outer bearing housings.
Therein, suitably, the pipe conduits are guided to one of the roller or roll ends, respectively.
One embodiment which is especially advantageously used when a roller ls to be provided with a closed coolant circuit, consists in that two neighbouring bearing housings of a roller or roll, respectively, are connected by one pipe conduit each ., .

and one or both of the outer bearing housings is (are) provided with a pipe conduit leading outside and the pipe conduits are interconnected by the coolant flow.
Furthermore it is advantageous for a time-saving roller exchange when the ends of the pipe conduits guided outside are connectable to a lubricant or coolant supply conduit, respec-tively, by means of a detachable quick lock.
These and further features of the invention shall now ~' be described in more detail by way of example only and with reference to the accompanying drawings, wherein:
Fig. 1 shows a schematically illustrated front view, Fig. 2 is a pertaining horizontal plan of a roller according to one embodiment of the invention multiply supported in a strand guide stand, Fig. 3 is a view analogous to Fig. 1 on a larger scale and partly in section, Fig. 4 is a view of a section along line IV-IV of Fig. 1 also on a larger scale, Figs. 5 and 6 are views analogous to Figs. 1 and 2 of another embodiment of the invention, Fig. 7 is a view according to Fig. 5 on a larger scale and partly in section, and - Fig. 8 is a view of a section along line VIII-VIII of Fig. 5, also on a larger scale.
With 1 the roller is denoted which - distributed over its longitudinal extension - has a number of bearing pins 2 and 2' mounted in bearing housings 3 and 3', the two bearing pins and bearing housings, respectively, arranged at the ends of the roller being denoted with 2' and 3', respectively. The bearing housings 3 and 3' are supported via bearing supports 4 on "
~3~745 carriers 5, backing the rollers, of a stationary strand guide stand. Pipe conduits 6, 6' arranged parallel to the axes of the roller 1 serve for supplying lubricant in the direction of the arrow to the individual bearing places of the roller 1, the pipe conduits 6' supplying the outer bearing pins 2' and the pipe conduits 6 supplying the inwardly arranged bearing pins 2 with lubricant. The pipe conduits 6 are guided outside through bores 7 of the bearing housings 3' arranged at the ends of the roller, whereby the bearing housings 3 and 3' are each secured against mutual rotation around the roller axis. Thus when a roller is inserted into the strand guide stand, only the outwardly arranged bearing housings 3' need be turned into the correct position, the inwardly arranged bearing housings 3 are turned together with and by the pipe conduits 6. Thus manipula-tions at the inwardly arranged bearing housings 3 can be omitted.
Quick locks 8 at the pipe conduits contribute to an even faster roller exchange.
All the pipe conduits 6, 6I can also be guided to one end of the roller only, for an even easier handling of the roller, and can there be collected in a central connection, so that for a roller exchange only one lubricant connection need be disconnected or connected, respectively. It is a further advantage that the lubricant supply conduits mounted in the stand need only be provided near one of the roller ends.
Figs. 5 to 8 are an embodiment of the strand guide according to the invention as it is advantageously applied when a cooling of the bearing places with a closed coolant circuit is installed. The coolant enters through a pipe socket 9 at one of the bearing housings 3' arranged at the ends, flows through the bearing housing des gned hollow in this case in the ..

direction of the arrow, the thin-walled bearing lid 3" of the ~ bearing housing 3' allowing for an intensive cooling of the ; side of the bearing housing facing the surface of the strand as well as of the bearing pin, and reaches the next bearing housing through the pipe conduit 6" connecting the bearing housings. After flowing therethrough, the coolant reaches the following bearing housings 3 up to the last bearing housing 3' in the same manner as described above, which bearing housing 3' again is equipped with a pipe socket 9' having a quick lock 8, which is connectable to the drain conduit. In a roller according to this embodiment, all the bearing housings are secured against mutual rotation by the pipe conduits 6", and when the roller is being inserted into the strand guide stand, only one of the bearing hausings need be aligned.
In order to arrange the coolant supply and drainage at one side of the roller, it is possible to lead the coolant drain conduit from the last bearing housing back to the roller end arranged opposite, to which end the coolant supply conduit is connected, the return conduit also being arranged axis-parallel to the roller and penetrating the bearing housings inthe manner illustrated in Fig. 1.
For rollers subjected to an especially great wear the embodiment shown in Fig. 1 can be combined with the embodiment according to Fig. 5~ whereby the bearing places of the roller are supplied with lubricant as well as with coolant.
The bearing housings 3 and 3' suitably are divided into bearing housing lower part and bearing housing lid. When using rollers that are divided at the bearing pins perpendicular relative to the axis, the parts of which are held together by ` 30 a centrically arranged bracing anchor, it is possible to use .

undivided bearing housings.
For a better conveying of the strand as well as for safe~
guarding that no standstill of a roller does occur during the continuous casting - this would lead to a destruction of the roller - the rollers 1 can also be connected at one end there-of with a drive, such as a slip-on hydraulic motor.
According to a further embodiment of the invention, each one of the hollow bearing housings is provided with its own coolant supply and coolant return conduits, the coolant conduits of the inwardly arranged bearing housings penetrating the outer bearing housings in the manner shown in Fig. 1, whereby, again, the bearing housings are secured against being rotated relative to one another.
