Definitions

  • the invention relates to a strand guide of a continuous casting plant for thin slabs, comprising guide rollers, which are mounted on opposite frames and through Tie rods are braced against stop surfaces, being assigned between each other Stopping surfaces of the frame designed hydraulic cylinders to stretch the tie rods are arranged.
  • Such a strand guide has become known from DE-A1 26 12 094, in which the frame supporting the bearings of the guide rollers by means of several tie rods are connected, the mutual distance between the frame parts by one each an annular bracket and spacer located a tie rod is intended.
  • the frame will be two with inclined helical surfaces bushings supported against each other twisted by a pressure medium cylinder. At a strand jamming, the bushings are rotated in the relieving direction.
  • DE-A1 43 06 853 is a strand guide of a continuous caster for Casting rolls of thin slabs are known, their frames by piston-cylinder units are connected, between the abutment surfaces of the upper and lower Frame a hydraulic ring cylinder and a spacer are arranged. With this device, the guide rollers mounted on the frame Casting rolls set in three defined positions.
  • the known strand guides are complex and prone to failure.
  • the invention is based on the following problem: With the generic Strand guidance depends on the actual strand cross section determining Distance of the guide rollers during the casting operation apart from Alignment state of the strand guide from the pretension of the tie rods and the Temperature. As a result, the strand guide emerging thin slabs result in wedge-shaped cross-sectional shapes, 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 create a strand guide with mechanical Tie rods against one another tense frame, in which a simple to Thickness deviations across the slab cross section lead to inaccurate alignment or uneven thermal expansion or wear of those mounted on the frame Guide roles in the casting operation can be compensated.
  • the invention proposes that hydraulic ring cylinders wrap the tie rods between the stop surfaces of the frame.
  • Fig. 1 In the continuous casting plant shown in principle in Fig. 1 is a continuous casting mold 1 for thin slabs 2 one from a first section 3 and a second section Subordinate 4 existing strand guide.
  • the cast slab 2 becomes by a driving device 5 formed by the support guide rollers 6
  • Strand guide 3, 4 promoted, with a liquid core due to cooling to Exit from section 4 is completely frozen.
  • the thickness profile is below the strand guide 3, 4 the slab 2 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 on opposite Frame 9, 10 stored.
  • the frames 9, 10 have approximately on both sides cylindrical end pieces 11, 12 with through openings 13 for tie rods 14, 15.
  • the tie rods 14, 15 are on their outside the frame 9, 10 projecting ends with nuts 16 provided, whereby the target distance of the support guide rollers 6th and thus the thickness of the solidified slab strand 2 is determined becomes.
  • the tie rods 14, 15 enclosing hydraulic ring cylinders 17, 18 arranged.
  • the Frame 9, 10 through the tie rods 14, 15 with nuts 16 with a Biased force that is greater than from the proportional section of the non-solidified strand acting ferrostatic Force on the strand guide.
  • the hydraulic ring cylinders 17, 18 is shown in FIG. 4 Assigned control device, the measuring devices from the links 7, computer 19, hydraulic pressure source 21, pressure relief valve 22 and multi-way valve 20 exists. From one of the measuring difference 7 determined forms the Computer signals for the pressure relief valve 22 and the multi-way valve 20, whereby the on the undersize side of the slab 2 located hydraulic ring cylinder 17 or 18 to achieve a uniform cross-sectional profile according to the required Expansion of the tie rods 14 and 15 are applied and a uniform slab cross section is achieved.
  • the invention is not based on the illustrated embodiment limited.
  • you can change the format known interchangeable spacers between the frame surfaces be arranged interchangeably, with usual hydraulic cylinders outside of the tie rods separate from the tie rods 14, 15 between the frames 9, 10 are arranged.
