Definitions

  • the invention relates to a strand guide, in particular for a steel slab caster, with a plurality of support segments supporting rollers, wherein a plurality of support segments are attached to a longitudinally integral longitudinal member, in particular an arcuate longitudinal member, and two adjacent support segments are jointly attached to each other by means of support elements arranged at their ends a support bracket supported on the side member are mounted.
  • the support straps are of the type To balance the balanciers on the one-piece side member and to provide a swivel drive, which engages the swivel bracket via a swivel lever, to compensate for roll dislocations between adjacent support segments.
  • This has the advantage that it is not necessary to pay attention to an exact positioning of the support straps on the one-piece side member, but it is very difficult or almost impossible to ensure an arcuate roller track of the rollers of all the support segments by pivoting the support straps and at the same time to avoid a roller offset.
  • pivoting the support tabs By pivoting the support tabs, a support segment is lowered and the second support segment mounted on this support tab is raised, causing kinks in the roller conveyor.
  • the pivoting mounting of the support straps is structurally very complex; in particular, it is difficult to ensure the function of the pivot drives after the continuous casting system has been in operation for a long time, since the arcuate strand guide belongs to the part of the continuous casting system which is most stressed by heat, cooling water, scale and rust.
  • Another disadvantage is the fact that longitudinal strains of the support segments cannot be taken into account by the support straps, especially since the positions of the support straps are not precisely defined from the outset, but only after actuation of the swivel drives, which are actuated until a possible roller offset disappeared, more or less randomly.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to create a strand guide of the type described in the introduction, in which a roller offset between adjacent support segments with certainty and in particular a deviation of the roller conveyor from the ideal circular arc path can be avoided, but simple manufacture of the one-piece longitudinal members carrying the support segments is ensured, measurement work can be reduced to a minimum and quick and easy installation and removal of the support segments is possible.
  • each support bracket is rigidly attached to the side member by means of two parallel fitting bolts, the fitting bolts of all the support straps are approximately in the neutral fiber of the side member and each support segment against the side member can be tensioned by means of a clamping device.
  • the production of the longitudinal beams is extremely simple, since the holes provided in the longitudinal beams for the dowel bolts can be produced on a coordinate boring machine with great accuracy and without great effort.
  • the manufacture of the carrier straps is particularly simple. In the event of a general overhaul of the system, the one-piece side members do not have to be removed. Rather, it is sufficient to remove and overhaul the support segments and the brackets.
  • each support bracket expediently has a recess which immovably receives the support element of a support segment and a recess which receives the support element of the adjacent support segment, which is preferably designed as a sliding block, with play, the play parallel to the strand guideway at the transition point from the one support segment is directed to the adjacent support segment.
  • the arcuate strand guide In order to ensure an offset-free connection of the arcuate strand guide to the adjacent strand guide parts of the continuous casting plant, advantageously engages in the support tabs provided at one end of the arcuate side member form a support segment adjacent to the arcuate strand guide part, such as a support segment of the bending zone and / or the straightening zone.
  • FIG. 1 shows a side view of a strand guide according to the invention and FIGS. 2 and 3 each show sections along lines II-II and III-III of FIG. 1.
  • a strand guide 1 of a continuous sheet casting installation has continuous, arc-shaped and parallel longitudinal beams 3, 4 for receiving a plurality of support segments 2, each of which is supported on the foundation 7 by means of bearings 5 and brackets 6, etc. at the lower end directly on the bearing 5 and at the upper end and in the center via hinge plates 6.
  • Each side member 3, 4 is formed from two parallel cheeks 8, between each of which support plates 9 are arranged to support the support segments 2, the support plates 9 on each side member 3, 4 are arranged in the longitudinal direction at a distance from one another, which corresponds to the longitudinal extent of the support segments 2 plus the distance between adjacent support segments 2.
  • Each support bracket 9 is rigidly fastened to the longitudinal beams 3, 4 by means of two fitting bolts 11 arranged approximately in the neutral fiber 10 of the longitudinal beams 3, 4.
  • each support bracket 9 has two U-shaped recesses 13, 14 which are arranged one behind the other in the longitudinal direction of the longitudinal supports and which receive support elements 15, 16 which are designed as bolts and are arranged laterally at both ends of the support segments 2 .
  • the recesses 13, 14 are open approximately in the radial direction to the center of the strand guide track 17, so that the support segments 2 can be removed in the direction of the center from the side members, the support elements 15, 16 sliding out of the recesses 13, 14.
  • the side walls of the recesses 13, 14 are directed in the direction of removal of the respective support segment 2, so that the side walls of the recesses 13, 14 receiving a support segment 2 are directed parallel to each of the support brackets 9, whereas the side walls of the recesses 13, 14 of a support bracket 9 are at an angle are directed towards each other.
  • each support bracket 9 receives a support element 15 of each support segment 2 immovably, whereas the adjacent U-shaped recess 14 of the same support bracket 9 receives a support element 16 of the adjacent support segment 2 to enable thermal expansion with play 18.
  • the support elements 16, which in this case are designed as sliding blocks, are located approximately in the center of the recess 14, so that there is play 18 in the longitudinal direction of a support segment 2 in front of and behind the support element 16.
  • the play 18 and thus the bottom of the recess 14 is directed parallel to the strand guide track 17 at the transition point 19 from a support segment 2 to the adjacent support segment 2.
  • clamping devices 20 For fixing the support segments 2 to the side members 3, 4 serve clamping devices 20. These clamping devices are formed by clamping screws which on the one hand connect the longitudinal beams 3, 4 and the cheeks 8 and the longitudinal beams 3, 4 mutually clamping bolts 21 and on the other hand tabs 22 welded to the support segments 2.
  • the support segments of the bending zone 23 and the straightening zone 24 adjacent to the arcuate strand guide 1 likewise have support elements 15, 16 which engage in the recesses 13, 14 of the support tabs 9 arranged at the ends of the arcuate longitudinal supports 3, 4, again the lower support element 16 of the bending zone 23 is designed as a sliding block and is displaceable in the recess 14 in the direction of the strand guide track 17.
  • the recess 14 is directed parallel to the strand guide track 17 and is open towards the mold.
  • the strand guide 1 described above can be manufactured with great accuracy without great effort by making the bores for the fitting bolts 11 in the side members 3, 4 on a coordinate boring machine.
  • the production of the support straps 9 is just as easy.
  • the support straps can also advantageously be provided in the horizontal rectilinear part of the strand guide 1, the adjacent support segments 2 'forming a rectilinear roller conveyor via the support elements 15', 16 'designed as bolts on support straps 9' on one rectilinear side members 3 'are attached.
  • the mounting of the brackets 9 ' is also accomplished here via dowel bolts 11, which have their axis in the neutral fiber 10' of the side member 3 '.
  • the invention is not limited to the exemplary embodiment shown, but can be modified in various ways.
  • a wedge connection can be provided instead of the clamping screws 20.
