Definitions

  • the invention relates to a supporting and guiding element for a continuous casting installation, in particular for a steel slab continuous casting installation, with two frame parts supporting the strand on opposite sides and having rollers, one of these frame parts being supported on a stationary support frame and the other frame part against the first Frame part can be adjusted or clamped with the interposition of intermediate pieces determining the roller spacing by means of at least one tensioning device, and wherein the frame parts are guided against one another by means of guides arranged on them and in which other frame part engaging.
  • Support and guide elements of this type are known for example from AT-PS 343 303.
  • the frame parts are connected to one another by means of tie rods, the tie rods also serving to accommodate the intermediate pieces which determine the roller spacing, and the tensioning devices for attaching or tightening the one frame part against the other are fastened to the tie rods. If you want to remove the frame parts, the media connections for the clamping devices must be disconnected. Furthermore, it is disadvantageous that, due to the fastening of the tensioning devices on the support and guide element, the tensioning devices must also be exchanged when the support and guide element is replaced. Furthermore, the tensioning devices in the known construction must be arranged within the area at risk of strand breakdown or within the area of the continuous casting system affected by the cooling water, so that the tensioning devices are heavily stressed and accordingly susceptible to failure.
  • the invention aims to avoid these disadvantages and difficulties and has as its object to develop a support and guide element of the type described in such a way that the tensioning device is not removed or replaced when the support and guide element is removed or replaced must and can be arranged outside the area at risk from a strand break or from the cooling water. Furthermore, when removing or changing the support and guide element, loosening of media connections for the tensioning device should be avoided.
  • the support frame surrounds the support and guide element in a frame-like manner, the tensioning device being fastened to a support of the support frame which engages behind the adjustable frame part and engaging on the rear side of the adjustable frame part.
  • the tensioning device lies loosely on the adjustable frame part, which ensures particularly simple and rapid removal of the support and guide element.
  • the tensioning device is connected to the adjustable frame part by means of a hook connection that is open in the direction of removal of the support and guide element.
  • the tensioning device advantageously has a sleeve which can be displaced along a bolt and has a preferably cambered base which bears against the adjustable frame part, the sleeve being expediently able to be pressed against the frame part by means of a self-locking screw tensioning device.
  • the sleeve projects through a protective wall covering the screw clamping device.
  • the sleeve of the tensioning device is expediently surrounded peripherally by a protective tube arranged at a distance from the sleeve.
  • FIG. 1 shows a view of the support and guide element in the direction of the strand axis
  • FIG. 2 shows a section along line 11-11 of FIG. 1 according to one embodiment in a schematic representation.
  • FIG. 3 shows a schematic illustration according to a further embodiment.
  • a strand 3 is supported and guided between the roller conveyors 1 and 2.
  • the rollers 4 of each of the two roller conveyors 1, 2 are fastened with their holders 5, 6 to a frame part 7, 8 in each case.
  • Each frame part 7, 8 is composed of longitudinal and cross members 10.
  • the two frame parts 7, 8 are guided to one another by means of bolts 12 extending transversely to the longitudinal axis 11 of the strand web, intermediate layers 13 being provided on the bolts, the number and thickness of which are selected according to the desired roller spacing 14 and which after pressing the two frame parts 7, 8 against one another Determine roller distance 14.
  • One 7 of the frame parts 7, 8 is supported by a hook 15 and a stop 16 on a stationary support frame 17, whereas the other opposite frame part 8 is movable relative to this fixedly suspended frame part 7 and can be adjusted or tightened against it.
  • the stationary support structure 17 surrounds the support and guide element composed of the two frame parts in a frame-like manner, which can be seen in particular from FIG. 1.
  • the stationary support structure 17 is formed from two cross beams 18, 19 arranged parallel to the rollers and from two further beams 20 which connect them and absorb tensile forces.
  • This tensioning device is essentially composed of a guide pin 23 rigidly mounted on the cross member 19, the axis 24 of which is approximately is directed at right angles to the roller conveyors 1, 2, two bushings 26, 27, which are adjacent to one another with threaded surfaces 25 and are rotatably mounted about these guide bolts 23, and a sleeve 28, which bears against the bush 26, which is closer to the adjustable or clampable frame part 8, into which the guide bolt 23 protrudes.
  • a lever 29 is mounted on one of the bushes and is connected in an articulated manner to the piston 30 of the pressure medium cylinder 22.
  • the inclination of the threaded surfaces 25, with which the sleeves abut one another, to the axis 24 of the guide pin 23 is chosen to be less than the friction angle corresponding to the associated coefficient of friction, so that the sleeves 26, 27 are also caused by forces caused by the strand 3 in the direction of the guide pin 23 Unloading the pressure cylinder 22 can not be rotated.
  • the sleeve 28 projects through a recess 31 in the cooling chamber wall 32, so that the actual tensioning device, ie the pressure medium cylinder and the two bushings, are arranged outside the cooling chamber receiving the support and guide elements.
  • the sleeve 28 is provided at its end abutting the adjustable frame part 8 with a cambered bottom 33 which lies loosely against this frame part.
  • the entire supporting and guiding element can therefore be removed immediately after loosening the tensioning device 21 without any connection with the tensioning device 21 having to be released.
  • the clamping device 21 remains in place when the support and guide element is removed. After installing a new intact support and guide element, it is only necessary to apply the tensioning device 21, as a result of which the support and guide element is fixed again to the support frame 17. The entire tensioning device 21 does not need to be taken into account when mounting the support and guide elements.
  • a protective tube 34 is drawn over the sleeve, which surrounds the sleeve at a distance 35.
  • This protective tube absorbs thermal, mechanical and corrosive stresses, which means that the sleeve is well protected against any deformation resulting from these stresses.
  • a hook 37 which extends over an extension 36 of the sleeve 28, is provided on the frame part 8 that can be adjusted or tightened, so that this frame part participates in displacement movements of the sleeve in the direction of the axis 24 of the guide bolt. Since the hook is open in the direction of removal of the support and guide element, which is indicated by the arrow 38, the fast interchangeability of the support and guide element is also given in this embodiment.
  • clamping device for example a pressure medium cylinder, which acts directly on the frame part that can be adjusted or tightened, can be provided.
  • the support and guide element described here can not only be used as a straight vertical element, as shown in the illustrated exemplary embodiments, but can also be used for curved strand guide elements, for example for the bending zone or for a support and guide element with an arcuate roller conveyor come.
