Definitions

  • the invention relates to a strand guide of a continuous casting plant for thin slabs, wherein guide rollers are mounted on opposing frames, which are braced against stop surfaces by tie rods.
  • a strand guide is known in which the frame supporting the bearings of the guide rollers are connected by several tie rods, the mutual spacing of the frame parts being determined by an annular bracket and spacers located on a tie rod.
  • two bushes supported with inclined helical surfaces are rotated by a pressure medium cylinder. In the event of strand jamming, the bushings are turned in the relieving direction.
  • a strand guide of a continuous casting plant for casting thin slabs is known, the frames of which are connected by piston-cylinder units, a hydraulic ring cylinder and a spacer being arranged between stop faces of the upper and lower frames.
  • the guide rollers mounted on the frame are set in three defined positions during casting rolling.
  • the known strand guides are complex and prone to failure.
  • the invention is based on the following problem:
  • the actual spacing of the guide rollers which determines the strand cross section, depends on the alignment state during the casting operation
  • Strand guidance depends on the tension of the tie rods and the temperature.
  • wedge-shaped cross-sectional shapes can result from the thin slabs emerging from the strand guide, since the strand cross-section is determined by the distance between the rollers in the area of final solidification.
  • the object of the invention is to provide a strand guide with a frame mechanically clamped against one another by tie rods, in which an inaccurate alignment or uneven thermal expansion or wear of the guide rollers mounted on the frame can lead to variations in thickness over the slab cross-section during casting operation.
  • the invention is based on the knowledge that the dimensional differences to be compensated for can be fully compensated for by the achievable expansion of the tie rods.
  • the invention proposes that hydraulic ring cylinders enclose the tie rods between the stop faces of the frames.
  • the hydraulic ring cylinders are connected to a hydraulic pressure source via a valve, to which a control signal is fed from a control system consisting of slab thickness measuring device and computer.
  • the distance between the opposite rows of rollers of the frame is corrected by continuously measuring the thickness of the slab sides to determine an undersize side of the slab, determining the required expansion of the tie rods on the undersize side from the dimensional difference and applying the pressure required to the hydraulic cylinders.
  • a continuous casting mold 1 for thin slabs 2 is followed by a strand guide consisting of a first section 3 and a second section 4.
  • the cast slab strand 2 is conveyed by a drive device 5 through the strand guide 3, 4 formed from support guide rollers 6, a liquid core as a result of the cooling until it emerges from the section 4 is completely frozen.
  • the thickness profile of the slab 2 is determined by measuring devices 7.
  • the slab 2 is then deflected by a bending roller 8.
  • the support guide rollers 6 of the second section 4 of the strand guide are mounted on opposite frames 9, 10.
  • the frames 9, 10 have on both sides approximately cylindrical end pieces 11, 12 with through openings 13 for tie rods 14, 15.
  • the tie rods 14, 15 are provided with nuts 16 at their ends projecting outside the frames 9, 10, as a result of which the desired spacing of the support guide rollers 6 and thus the thickness of the solidified slab strand 2 is determined.
  • the tie rods 14, 15 enclosing hydraulic ring cylinders 17, 18 are arranged between mutually associated end faces of the end pieces 11, 12.
  • the frames 9, 10 are prestressed against the hydraulic ring cylinders 17, 18 by the tie rods 14, 15 with nuts 16 with a force which is greater than the ferrostatic force acting on the strand guide from the proportionate section of the strand which has not solidified.
  • the hydraulic ring cylinders 17, 18 is assigned a control device shown in FIG. 4, which consists of the components measuring devices 7, computer 19, hydraulic pressure source 21, pressure relief valve 22 and multi-way valve 20. From a dimensional difference determined by the measuring devices 7, the computer forms signals for the pressure relief valve 22 and the multi-way valve 20, as a result of which the hydraulic ring cylinders 17 and 18 located on the undersize side of the slab 2, in order to achieve a uniform cross-sectional profile corresponding to the required expansion of the tie rods 14 and 15, respectively be charged and a uniform slab cross section is achieved.
