Definitions

  • the invention relates to a continuous caster with a mold mounted on a frame-like lifting table that oscillates with respect to a supporting frame and is guided by guides relative to the supporting frame in the axial direction of the mold cavity, two eccentric shafts being provided parallel to one another and each being arranged on a frame side of the lifting table , which each extend approximately over the entire frame side of the lifting table and on which the lifting table is supported close to one of its corners by means of supporting means articulated on the eccentric shafts.
  • a continuous caster of this type is known from DE-A 3000117.
  • the support means are formed by leaf springs in this known system.
  • the disadvantage here is that the movement of the leaf springs can cause the lift table movement to deviate from the strand guideway, which causes skewing or tilting of the mold relative to the ideal strand guideway.
  • the lifting table is more or less raised at the point at which the one support means is articulated on the eccentric shaft than at the point at which the second support means belonging to this eccentric shaft is provided.
  • the occurrence of vibrations which disturb the movement of the mold cannot be avoided.
  • the invention aims to avoid these disadvantages and difficulties and has as its object to provide a continuous caster of the type described in which an exact lifting and lowering of the lifting table is ensured, but with few moving parts the sufficiency is found and the movements of the Disturbing vibrations can be avoided.
  • the support means are designed as connecting rods, two connecting rods arranged at the ends of one of the eccentric shafts being rigidly connected to one another and supported together on a support axis which in turn is supported at the corners of the lifting table.
  • the solution according to the invention allows, in addition to the rotation of the two eccentric shafts at the same angle, also an exact four-point mounting of the frame-like lifting table, so that the lifting table remains evenly guided even under locally changing loads due to friction occurring between the mold and the strand. This is particularly important in the case of lifting tables for molds, with which strands with a slab cross-sectional format are cast.
  • connecting rods as support means is known per se (EP-B 0073160, EP-A 0124362), but in the continuous casting systems in which connecting rods are provided, the connecting rods can be moved independently and independently of the adjacent connecting rod, so that an exact one Synchronization of the connecting rods is not guaranteed.
  • An advantageous, particularly robust construction is characterized in that two connecting rods arranged at the ends of an eccentric shaft are rigidly connected by means of a tube arranged concentrically to the support axis, which is pivotally mounted on the support axis, and that the support axis is rigid at the corners of the frame-like lifting table , preferably by means of trestles.
  • each eccentric shaft preferably has two cranks which are arranged at the ends of a cylindrical shaft part and are rotatably mounted on the supporting frame and the shaft part of each eccentric shaft is surrounded by a tube which is supported at both ends of the shaft part via eccentric bushings, wherein the eccentric sleeves are non-rotatable and rotatable with respect to the tube, the tube is releasably attached to the eccentric sleeves and can be fixed in different angular positions with respect to the cranks, and the connecting rods are articulated on the tube near the ends thereof.
  • a flange is expediently fastened to the end of the tube and a counter flange abutting against this flange on the cranks and the flange can be fixed to the counter flange by means of connecting pieces passing through the flange and the counter flange.
  • FIG. 1 shows a plan view of a lifting table with the mold lifted off
  • FIG. 2 shows a section along line 11-11 of FIG. 1
  • FIG. 1 shows a section along line 111-111 of FIG 2 show.
  • FIG. 4 shows a modified embodiment in a representation analogous to FIG. 3.
  • a mold 2 shown with dashed lines in FIG. 2 can be placed on a frame-like lifting table 1 which is rectangular in plan, the mold 2 partially projecting downwards through the lifting table 1.
  • the lifting table 1 which is designed as a hollow box girder, coolant supply and discharge pipes, not shown, open.
  • the lifting table 1 serves as a support for the mold 2, the mold being supported on the lifting table 1 with laterally arranged brackets 3 and being connected in line with the corresponding coolant supplying and discharging cavities of the lifting table.
  • the lifting table 1 performs an oscillating movement with respect to a stationary support frame 4, this movement being intended to oscillate exactly vertically in the case of a mold 2 with a straight axis 5 of the mold cavity 6.
  • An important prerequisite for good strand quality is the exact observance of the desired oscillation; in particular, misalignments of the lifting table 1 (and thus tilting of the Kokil le 2) and unintentional vibrations are avoided, since such misalignments and vibrations can damage the extremely thin strand shell of the strand emerging from the mold.
  • each eccentric shaft 7, 7' has a shaft part 12 which is rotatably mounted at the end on the support frame 4 by means of bearing blocks 11 and at the ends of which a crank 13 is provided.
  • Each of the cranks 13 is mounted in its own bearing bush 15 by means of a roller bearing 14.
  • the bearing bushes 15 assigned to an eccentric shaft 7, 7 ' are each attached via connecting rods 16 to the ends of a tube 17 which has approximately the length of an eccentric shaft 7, 7'.
  • Each tube 17 is penetrated by an axis 18 on which the tube is pivotally mounted by means of roller bearings 19 arranged in the plane of the connecting rods.
  • roller bearings 14 and 19 plain bearings could also be provided.
  • the ends 20 of the axis 18 protrude beyond the tube 17, which is sealed with respect to the axis 18 by means of a closure cover 21, and are rigidly inserted into support brackets 22 which are fastened to the underside 23 of the lifting table 1 at the corners 24 thereof.
  • a drive motor 25 is arranged symmetrically between them, just to the side of the lifting table 1 on the supporting frame 4, which is coupled to both eccentric shafts 7, 7 ' via drive shafts 26, 26 ' and corner gears 27, 27 ' . Due to the symmetrical arrangement of the drive motor 25 centrally between the eccentric shafts 7, 7 ', an identical angular position is always ensured for both eccentric shafts 7, 7' with the least effort, so that the lifting table 1 oscillates in a precisely horizontal position - without any misalignment.
  • the eccentric shafts 7, 7 ' are supported on the end side, ie by means of the cranks 13 via bearing blocks 11 on the supporting frame 4, and the connecting rods 16 are rotatably supported on the shaft part 12 of the eccentric shafts arranged between the cranks 13.
  • Each shaft part 12 is surrounded by a tube 28 which is supported at the ends of the shaft part 12 via eccentric bushes 29.
  • the connecting rods 16 are rotatably supported on the tube 28 by means of roller bearings 30, in the vicinity of the eccentric bushes 29 arranged at the ends.
  • the eccentric bushes 29 are fixed non-rotatably on the shaft part 12, but can be rotated relative to the tube 28, as a result of which the eccentricity 31 between the axis 32 of the tube 28 and the axis 33 of the cranks 13 can be changed.
  • a flange 34 is fastened to the tube 28 at one end and bears against a counter flange 35 mounted on the adjacent crank 13.
  • the two flanges 34, 35 are releasably connected to one another by connecting pins 36 passing through them.
  • the two flanges 34, 35 are rotated against each other after loosening the connecting pins 36 by the amount which corresponds to the desired eccentricity 31 and fixed in this new position against one another by inserting the connecting pins 36.
  • a key extension is expediently provided on a drive shaft 26, 26' extending from the drive motor 25 to the eccentric shaft 7 or 7 'or to the corner gear 27 or 27 ' .
  • the lifting table 1 is guided through the connecting rod 16 in the axial direction of the eccentric shafts 7, 7 '.
  • a guide formed from spring bands 37 is arranged symmetrically to the central plane 38 arranged, the spring bands 37 are attached with their ends 39 to the lifting table 1 and in the center on a bracket 40 rigidly arranged on the stationary support frame 4.
  • these spring bands 37 are only shown in FIG. 2.
