Definitions
- the invention relates to a strand guide roller with at least one roller shell and at least two support shafts, wherein in each case two support shafts are rotatably connected to a roller shell and each support shaft is rotatably supported in a support bearing.
- a strand guide roller of this type is already known from DE-A 24 23 224.
- adjacent roller shells are connected by a support shaft in the axial direction, which is rotatably supported in a support bearing and engages with mutually away stub shafts in axial recesses of the adjacent roller shells.
- a non-positive connection between the support shaft and the respective roller shell is effected by a screw connection between the two components and by cooperating radial support surfaces on the support shaft and the roller shell, whereby an additional safeguard against loosening during plant operation is achieved.
- this constructive solution has not been proven in practice, since this distortion of the components does not withstand the rough metallurgical plant operation.
- a one-piece strand guide roller is known in which a roller shell is permanently connected by a peripheral weld with two support shafts.
- the roller shell is covered with an abrasion-resistant, corrosion-resistant protective layer. Damage to individual components of the strand guide roller usually lead to their total loss and high spare parts costs.
- the coolant is distributed over predominantly radially or inclined to the roller rotation axis inclined coolant channels from the roller center to the periphery of the strand guide roller, there via ring lines , guided by parallel to the roller axis rechtrechtete coolant channels near the roller shell surface and collected in an analogous manner and directed back to the center.
- usually ring or pf ropfenförmige sealing body are screwed or welded to the roller shell end faces. Due to the high thermal and material stress in the strand guide roller these sealing methods are complex, very sensitive and prone to failure.
- multi-layer roller shells for example, by a keyway, rotatably and releasably secured to the core shaft.
- the multilayer structure of the roller shell is effected by individual cylinder sleeves, which are rotatably connected by a full-surface shrinkage connection of the opposite cylinder jacket surfaces.
- At the contact surfaces of the cylinder sleeves are the easy to produce coolant channels (WO 2005/016578, WO 02/02253).
- the present invention aims to avoid these difficulties and disadvantages and has as its object to propose a strand guide roller, which consists of a plurality of easy-to-manufacture components, which are interconnected so that the compound withstands the intense thermal and mechanical stresses during the casting operation, the consists of easy to manufacture components and the disassembly and possibly the reuse of expensive components, such as preferably roll coats and bearing housings enabled.
- This object is achieved in that the roller shell is rotatably connected to him on both sides supporting support shafts by shrink connections or press-fit connections.
- the intermediate support bearing takes place in principle on Rolleneinschnürungen, which takes place through the shrunk into the roller shells support shafts with a smaller diameter.
- the shrink-fit or press-fit connection is designed so that stationary and nonstationary roller loads and drive torques can be reliably transmitted in the case of driven strand guide rollers and sealing functions for the coolant guide are reliably ensured.
- the design of the shrink or press-fit connection takes into account special operational load cases, such as
- the described assembly arrangement with shrink-fit or press-fit connection results overall in the following advantages:
- the simple plug-in design allows easy assembly of the long strand guide rollers and cost-effective production of the individual components.
- Multi-part strand guide rollers do not require split intermediate support bearings.
- the strand guide roller is suitable due to the particularly economical production as a cheap one-way roll.
- the sealing of the coolant guides can be done largely without sensitive, synthetic sealing elements or without welds.
- Each support shaft comprises at least one stub shaft whose outer circumferential surface with an inner circumferential surface of a recess in a roller casing forms the shrink fit or press-fit connection.
- the basic structure of the components forming the shrink or press-fit connection is the same both at the end regions of the strand guide roller and in the regions between adjacent roller shells.
- two adjacent roller shells are non-rotatably connected by a support shaft centrally supported by a support bearing.
- the strand guide rollers are equipped with an internal cooling, two embodiments are particularly useful:
- the roller cooling of the roller shell is penetrated by at least one coolant channel and this coolant channel is arranged at a constant distance from the cylindrical roller shell outer surface of the roll shell.
- the coolant channel forms, for example, a circumferential annular space.
- the roller shell is penetrated by a plurality of coolant channels, which are arranged at a constant distance from the cylindrical roller shell outer surface.
- the essentially radial feed and discharge lines for the cooling medium enforce the shrink connection between the support shaft and roller shell.
- the supply and discharge lines can also be arranged inclined to the axis of rotation of the strand guide roller.
- a distributor sealing ring is arranged between the roller shell and the support shaft, which forms a coolant distribution line with the roller shell into which the substantially radial supply or discharge lines and paraxial coolant channels open and wherein this distributor sealing ring with the roller shell and with the support shaft forms a rotationally fixed shrink connection or a press connection.
- roller cooling passes through a centrally guided in the axial direction coolant channel with a constant cross section, the alternately successive support shafts and roller shells.
- This Achkühlung is characterized by its simplicity and cheap construction particularly.
- the described shrink or press-fit connection can be used in the connection to the drive elements by a drive shaft connection of a driven strand guide roller with a support bearing centrally supported support shaft is rotatably connected by a shrink connection or by a press-fit connection.
- the sealing of the coolant channels and coolant distribution lines via distribution or sealing rings introduced by shrinkage or interference fit into the roller shell eliminates the need for sensitive, self-contained sealing elements and welded connections.
- designed as a floating bearing support bearings of the strand guide roller are formed by rolling bearings whose rolling elements can compensate for operational axial displacements and misalignments.
- toroidal bearings can be used, as described for example in German Utility Model DE 200 21 514 U1.

- FIG. 2 shows a strand guide roller according to the invention with three roller shells and a central roller cooling
- FIG. 3 shows a cross section through the strand guide roller with a representation of the coolant supply along the section line A-A in Figure 1,
- Fig. 4 is a partial section of the strand guide roller with the involvement of a distributor sealing ring for coolant passage.
- FIG. 1 The figure representations show strand guide rollers according to the invention in a schematic representation, as they are suitable, for example, for use in a strand guide of a continuous casting for the production of metal strands of large strand width with slab or thin slab cross-section.
- Identical or equivalent components in different embodiments are identified by the same reference numerals.
- the non-driven, two-part strand guide roller shown in Figure 1 in a longitudinal section comprises two roller shells 1, 2 and three support shafts 4, 5, 6, wherein the support shafts are rotatably supported in support bearings 8, 9, 10.
- the support shaft 5 arranged between two roller jackets 1, 2 terminates in two stub shafts 12, 13 which are directed away from one another in the axial direction and project into cylindrical recesses 14, 15 of the adjacent roller jackets 1, 2.
- the non-positive connection between the Stub shafts 12, 13 and the roller shell 1, 2 is produced by a shrink fit or a press-fit connection, which takes into account the prevailing thermal and mechanical loads during the transport of a steel strand through the strand guide.
- Two at the ends of the strand guide roller, the roller shells 1, 2 supporting support shafts 4, 6 each have only one stub shaft 16, 17, which in recesses of the roll shells 1, 2, forming a shrink or press-fit connection, are used.
- the strand guide roller is equipped with a peripheral cooling designed as internal cooling, which is shown in Figures 1 and 3.
- the coolant inlet into the support shaft 4 is effected by a rotary inlet 21 coupled to the front side.

- the coolant feedthrough for the roller casing 2 is repeated analogously to the described coolant feedthrough in the roller casing 1.
- the centric coolant channel opens into a rotary inlet 21a through which the coolant flowing through the strand guide roller is discharged again.
- the coolant lines are guided so that they extend in the region of the shrink connection of the support shaft in the roller shell or back, so that the dense shrink joint simultaneously acts as a seal against coolant leakage.
- FIG. 2 shows a diagrammatic view of a three-part strand guide roller which comprises three roller shells 1, 2, 3 supporting shafts 4, 5, 6 carrying these roller shells and support bearings 8, 9, 10, 11 rotatably supporting these support shafts.
- the roller shells and the support shafts are, as previously described with respect to the strand guide roller according to Figure 1, by a shrink or Press fit connection positively connected.
- the coolant feedthrough takes place through a centric coolant channel 28, which passes through the successive support shafts and roller shells in the axial direction.
- rotary feedthroughs 21 are provided for the supply and discharge of the coolant, of which only the rotary feedthrough for the coolant supply is shown.
