  • a roller device comprising a traverse and at least one roller element mounted on the traverse roller element, wherein in the traverse at least one conduit means for conducting at least one medium is provided and the roller means is provided for forming a strand-guiding segment of a casting machine.
  • roller traverses (traverse with mounted roller) were used only in foundries and not in segments. In cast sheets, the rollers with traverse must be separately removable, since the removal of the pouring arc always means a longer downtime and thus loss of production. Since the support braces are arranged to support the rollers in a casting in the casting direction, the roller traverses have a comparatively large moment of resistance (high height) for the support of the rollers, which is significantly greater than the moment of resistance of the media used in segments.
  • Casting arc (strand guide): The casting arc is an old design, the z. B. was used in vertical turn-off systems (and will), wherein the entire arc lying in the arc of the proportion of the strand guide is summarized in terms of mechanical engineering in the pouring arc, i. the number of pairs of rolls is typically on the order of 25-45 pairs of rolls; the support of the casting roll for the rollers with roller traverses via support braces, which are arranged in the casting direction; when using roller traverses they are designed to support the roller with a comparatively high resistance moment (high height, for example at Arcelor Mittal Steel Eisendazzlingnstadt 100mm thick) (very robust construction).
  • Segment (strand guide) Newer design of strand guides: The number of pairs of rolls max. 10 in the bow section and max. 14 - 16 in the vertical part or bent part of the strand guide (especially for smaller roll diameters); in the arch part there are always several segments; the support braces for the rollers in the segment are located under the roller bodies, ie the support braces are perpendicular to the casting direction. The leadership of the pipes for a role is usually along the support braces; the rollers are not replaced in the system, but in the segment workshop; To do this, the entire segment is replaced. The upper frame and lower frame of the segment form a unit; The removal of the segments from the strand guide always takes place upwards.
  • Arc segment (strand guidance): Like segment with max. 10 roller pairs, wherein the roller pairs are geometrically arranged on a circular arc section.
  • the conduit means are provided for the media in the form of bores, in particular deep hole drilling, in the traverse, in the form of closable with lids channels in the traverse and / or in the form of laid within the traverse piping.
  • the roller device can be constructed as a complete module and the corresponding guided in the Traverse conduit means for the media can be fully tested and pre-adjusted already in this pre-assembled state.
  • a segment can be repaired in less time and with less effort.
  • a possibly damaged roller device for example within a segment comprising 14 roller devices, can be easily exchanged. Since the roller device is preassembled, pre-tested and pre-adjusted, the replacement of the reel unit in the segment can proceed swiftly. Accordingly, the repair effort and repair times in the segment workshop compared to conventional segments can be reduced.
  • the roller device can be constructed so that in the traverse additional conduit means are provided for at least one other medium, in particular for the conduction of a cooling medium of a secondary cooling (single or two-fluid cooling), a power supply and / or signal routing for sensors or switching elements.
  • additional conduit means are provided for at least one other medium, in particular for the conduction of a cooling medium of a secondary cooling (single or two-fluid cooling), a power supply and / or signal routing for sensors or switching elements.
  • the respective media connections communicating with the conduit means in the crossbeam are provided at one end face, longitudinal side or rear side of the crossbeam.
  • the respective inlets and outlets for example for the cooling medium circuits, the grease circuit, the power supplies and the sensor and switching devices merely by simply connecting coupling devices at the appropriate media connections with the Traverse to connect.
  • the Traverse can be designed so that the media connections are automatically coupled by placing the Traverse on a segment frame with the respective leads.
  • An efficient connection device can for example also be provided via suitable coupling elements, such as hybrid connectors, water retaining plates with flat seals, connecting pipes with double-sided O-rings, etc., so that the connection of the respective inlets and outlets to the roller device can easily and reliably take place.
  • suitable coupling elements such as hybrid connectors, water retaining plates with flat seals, connecting pipes with double-sided O-rings, etc.
  • the plug, coupling and coupling elements are designed so that they can lead at least two media simultaneously. In this way, the respective connection can be carried out more efficiently, since the number of coupling operations can be reduced.
  • the respective media channels in the traverse can be provided as milled channels, which is closed, for example, on the back of the traverse, so the side facing away from the slab of the crosshead with a lid, so that for maintenance or cleaning only this lid must be opened to service the respective cooling media channels.
  • it can also open channels or provided with silicone sealed channels be in which the conduit are laid. Open or sealed with silicone channels are preferably provided on the side facing away from the slab of the crosshead, so the "back" of the traverse.
  • extending along the traverse and firmly connected to this conduit means are provided.
  • An advantage of the design of the trusses in the proposed form is that by placing the trusses on the segment frame support bars can be omitted in the segment frame, as these are then formed by the traverse. Accordingly, every 2nd or 3rd support can be omitted in the segment frame.
  • segment frame structure in which a plurality, for example seven, roller devices are to be received becomes clear is simplified, since separate pipe connections for coolant circuits or signal lines need not be provided, or at least not in the hitherto necessary extent, when the trusses are coupled in the casting direction one behind the other.
  • Various signal lines for different measuring tasks can be recorded in the media supply and distribution devices within the crossbar. These measurement signals can then be tapped at a central location, for example at the front, at a portion of the long side, or at the rear of the crossbar, for example, via a multi-function plug, intelligent terminal, data bus connection, or other efficient manner without signal lines would have to be relocated to the respective sensors outside the housing of the traverse. Accordingly, the routing can be made more efficient here and the corresponding signal lines are no longer in the thermal and mechanical danger zone of the casting line.
  • Another advantage of this is that the sensors of the roller device already in the modular state, ie before the roller device is installed in a segment, can be completely pre-assembled, pre-tested and preset or adjusted, since the roller device can form a self-contained system.
  • the individual conduit means for the different media can also be fully tested for function. Due to the modular design and the complete functional test, the installation times in the respective segments can be significantly reduced.
  • a media circuit for the secondary cooling can also be accommodated in the traverse.
  • water distribution chambers are advantageously provided for the nozzles in the roller line and it can also be provided switching valves in or on the traverse to turn on and off individual nozzles, for example, to provide a secondary cooling for different strand widths.
  • a cooling circuit can be continuously produced from a first roller unit to the last roller unit, quasi in a series connection, without requiring separate piping of the traverses located in the segment to take place.
  • a coolant supply line can be connected to the first roller device, the coolant then flows through all adjacent roller devices and the coolant outlet is connected to the last roller device. In this way, the number of externally supplied terminals can be further reduced dramatically.
  • Such a construction is of course also conceivable for measuring signals which can be transferred by means of a media connection between the respective roller devices, so that a single connection of a measuring bus to one side of a segment can be sufficient to be able to pick up the signals of all the roller units of the segment.
  • the individual roller devices can be connected in series with respect to one or more of the media circuits.
  • the traverses can be formed by the geometric configuration so that they replace at least part of the tunnel cooling chamber plates.
  • This can be achieved, in particular, by designing the formations of the cross members in their transverse direction, that is, in the casting direction (perpendicular to the respective roller axis), such that the distances between the individual roller assemblies become small. Accordingly, the water vapor generated by the secondary cooling can be efficiently withdrawn via the respective suction devices and the corresponding blowers must not be oversized because the proportion of false air that is drawn through the gaps between the trusses, remains moderate. In this way, it is also possible to dispense with providing separate weld-in plates between the traverses, in order to form the respective cooling chamber. Also, this can be significantly increased in the maintenance process and during the assembly of respective segments, the efficiency in assembly.
