Definitions

  • the invention relates to a support roller frame for metal, in particular Continuous steel casting plants according to the preamble of claim 1.
  • a generic supporting roller frame is known from DE 196 06 308 B1.
  • This support roller stand is in straight or curved segments with roller carriers divided, with several roles combined on a role carrier.
  • Each two as a rigid frame element in the form of a sheet metal welded construction
  • Trained roller supports for parallel faces are on both sides attached next to the casting strand cross-section holding elements.
  • the Roles are stored on both sides in bearings, the housing of which in turn matches the Roller carriers are connected.
  • Both frame elements face each end a cantilevered continuation, between which one in the form of a sheet metal welded construction formed side element pressed in and releasable via Expansion screws are connected to the two frame elements. That so
  • the bending and torsion-resistant support roller segment formed is smooth and flat Inner surfaces.
  • Both frame elements are in the same direction as the strand extending and T-shaped supports provided on which releasable the respective bearing housing is attached.
  • the coolant supply and removal is integrated in the frame element and the also cooled bearing housing is over a passage arranged in the T-shaped support with the cooling medium supply or -delivery connected.
  • the object of the invention is to provide a support roller frame for metal, in particular Steel continuous casting systems to specify that with the same bending and Torsion resistance in the sense of simplified maintenance easier accessible and usable for a dry and wet driving style.
  • a further task is to guide the coolant in the Simplify frame element.
  • this is achieved by a frame element which as Carrying element at least two parallel at a distance from each other and transverse to Strands running tubes. There is a between the tubes stiffening web plate welded in. On the outer surface of the external pipes are each a holding plate pointing to the strand attached, between which the support carrying the rollers is welded. At internally cooled rollers, the pipes act as coolant supply or removal provide a connection spigot on the outer surface are.
  • connection of the frame elements thus formed with the side elements takes place via the cantilevered continuation known per se, which is adapted to the Pipe construction a cone-shaped, press-fit into the pipe Section and then a flat, on the frame elements has facing narrow sides of the side elements lying section.
  • the frame element advantageously has three symmetrical spacings arranged tubes as a support element, the middle tube with a Connection socket for the splash water is provided. So it can also be easier Optionally, a wet driving style of the support roller frame can be selected.
  • Tubes have a coaxially arranged displacement tube, the one has a smaller outside diameter than the inside diameter of the Support element.
  • Figure 1 is a section and in Figure 2 in a side view Segment of a support roller stand designed according to the invention is shown.
  • This embodiment is a curved segment for one Continuous sheet caster shown.
  • This segment has three as a supporting element the upper or lower frame element forming symmetrically arranged tubes 1 - 6 on.
  • the pipes 1 - 6 are transverse to the direction of the strand.
  • Figures 3 and 4 show web plates 7-10 arranged.
  • External tubes 1, 3 and 4 6 are on the outer surface for Strand-pointing holding plates 11, 12, 13, 14 attached.
  • a carrier is attached, the three sections 15.1, 15.2, 15.3, 16.1, 16.2, 16.3.
  • At each support section are means Screws attached three pairs of rollers.
  • the respective frame element is therefore formed by three pipes 1 - 3 or 4 - 6, intermediate web plates 7, 8 or 9, 10, external holding plates 11, 12 or 13, 14 and carrier 15.1-15.3 or 16.1 - 16.3.
  • the pipes 1 - 3 and 4 - 6 are with at both ends projecting extensions 26, 26 '- 28, 28' or 29, 29 '- 31, 31'.
  • Each Continuation has a peg-like, which can be fitted into the respective pipe 2, 5 Section 32, 32 ', 33, 33' and then a flat running Section 34, 34 ', 35, 35'.
  • the latter section 34, 34 ', 35, 35' is like this formed that a side element designed as a sheet metal welded construction 36 and 37 between the upper and lower frame member Expansion screws 38 - 43 is releasably attached.
  • the inner surfaces of the side elements 36, 37 are smooth, so that no dirt nests can form at this point.
  • Around the segment in the supporting structure of the support roller frame (not shown here) to be able to hang on the side elements 36, 37 two to the outside extending pins 44, 44 ', 45, 45' arranged. There is a spigot as losund the other pin is designed as a fixed bearing.
  • the lower part shows the bearing 46 ', 47', 48, 49 of a split roller 21.1 ', 21.2'. This is intended to make it clear that this is according to the invention trained support roller frame for the installation of one-piece continuous Support rollers, as well as for divided support rollers.
  • Splash water line 50, 50 ', 51, 51' provided ( Figure 4).
  • the middle tube 2, 5 For this purpose, each has two connecting pieces 52, 52 ', 53, 53' on the outer surface of the tube 2, 5 are arranged.
  • all pipes 1 - 6 are included a coaxially arranged displacement tube 54-59, this Displacement tube 54-59 has a smaller outer diameter than that Inner diameter of the respective pipe 1 - 6.
