Roller device

Abstract

A roller device assembly, in particular for forming a strand guiding section ( 100 ) of a casting machine includes at least two roller devices each having a cross beam ( 30 ) and at least one roller element ( 10 ) supported on the cross beam ( 30 ) by means of roller bearings ( 20, 22 ), wherein guiding means for at least three different media are provided in the cross beam ( 30 ).

What is claimed is: 
     
         1 . Roller device assembly, comprising two roller devices ( 1 ) for forming strand-guiding segments ( 100 ) of a caster and mountable in a segment frame of the caster as a pre-assembled module adjacent to each other, each roller device comprising a cross-beam ( 30 ), at least one roller element ( 10 ) supported on the beam; roller bearings ( 20 ,  22 ) for supporting the at least one roller element, and conduit elements ( 310 ,  320 ,  330 ,  340 ,  350 ) provided on the cross-beam ( 30 ) of each roller device for at least three different media, wherein at least one of the conduit elements is provided in the form of a channel ( 52 ) on a rear side  38  of the cross-beam ( 30 ), wherein the cross-beams ( 30 ) of the adjacent roller devices extend side-by-side along their longitudinal extent, and wherein cover means in form of a reclosable roof or silicone is provided for closing respective channels ( 52 ). 
     
     
         2 . A roller device assembly according to  claim 1 , wherein each roller device comprises at least one medium connector ( 40 ,  42 ,  44 ) communicating with the at least one of the conduit elements and provided on an end side ( 32 ) of the cross-beam, on a longitudinal side ( 36 ) of the cross-beam, or on a rear side ( 38 ) of the cross-beam ( 30 ). 
     
     
         3 . A roller device assembly according to  claim 2 , wherein the at least one medium connector ( 40 ,  42 ,  44 ) is formed as one of a socket, a coupling, a connector element, a hybrid socket, a water board with a gasket, a connection pipe with O-rings on both sides, or a data bus socket. 
     
     
         4 . Roller device assembly according to  claim 2 , wherein the at least one medium connector is arranged on the longitudinal side ( 36 ) of the cross-beam ( 30 ) and is so arranged that it can communicate with a corresponding medium connector ( 42 ,  44 ) in the cross-beam of an adjacent roller device ( 1 ), providing a direct connection of the medium connectors in both cross-beams of the corresponding roller devices. 
     
     
         5 . A roller device assembly according to  claim 1 , wherein the conduit elements comprise at least two conduit elements ( 310 ,  320 ,  330 ,  340 ,  350 ), respectively, for conducting at least two of the following media:
 cooling medium for inner cooling of the roller, cooling medium for secondary cooling, hydraulic medium for a hydraulic control circuit ( 342 ), compressed air medium for a pneumatic control circuit, power medium for an electrical power supply, power medium for electrical control signals, power medium for electrical measurement signals, power medium for optical measurement signals or electrical and/or optical bus system ( 352 ), and wherein medium connectors ( 40 ,  42 ,  44 ) are provided on an end side ( 32 ) of the cross-beam ( 30 ), a longitudinal side ( 36 ) of the cross-beam ( 30 ), and/or a rear side ( 38 ) of the cross-beam ( 30 ) for communicating with respective conduit elements, wherein the medium connectors ( 40 ,  42 ,  44 ) are formed as a socket, a coupling, or a connector element, and wherein a single socket, a single coupling, or a single connector element communicates at least two media with the cross-beam.   
     
     
         6 . A roller device assembly according to  claim 1 , wherein the roller device and the adjacent roller device are provided in the segment frame. A roller device assembly according to  claim 1 , wherein at least one of the cross-beams ( 30 ) has an extension in a cast direction that forms, with the cross-beam of another adjacent roller device, a roof of a cooling chamber, and contacts the cross-beam of the another adjacent roller device substantially without any clearance.
