Definitions

  • the invention relates to a starting strand for continuous casting plants, in particular steel slab continuous casting plants, with link bodies which are articulated to one another by means of articulation pins, wherein one articulation pin in each case passes through aligned bores of comb-like intermeshing end parts of adjacent link bodies.
  • different strand thicknesses can be used in certain thickness ranges and the same starting line are used, the starting head corresponding to the respective casting thickness being connected to the link body of the starting line.
  • the difference in thickness between the starting head and the link bodies is very large, there must be a plurality of transition link bodies which widen in a wedge shape to the starting head and which must be replaced together with the starting head. Up to now, these transition links have also been replaced by removing the link pins connecting the link bodies.
  • the starting head is designed as a "permanent head", i.e. the starting head is in a direct cast connection with the cast strand and can be detached from the cast strand by means of a separating device arranged in the strand guide. After loosening, the start-up strand is conveyed out of the strand guide by means of a lifting device, for example by means of a crane or a seesaw.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to create a starting strand of the type described above, which is divided into two or more parts transversely to its longitudinal axis easily, quickly and without great effort, in particular without destroying a limb body can be.
  • a permanent head it should also be possible to avoid casting termination if the permanent head cannot be separated from the cast strand, and both the start-up strand and the cast strand should always be able to run separately from the separation point provided in the system.
  • end parts of a link body are provided with laterally projecting collars against the end parts of the adjacent link body and peripherally surrounding the bore, the collars resting on support surfaces from recesses open to the top of the approach line at the end parts of the adjacent link body .
  • the laterally projecting collars are formed by bushings inserted into the end parts of the link body and the recesses are U-shaped.
  • hinge pin passes through the bores of the end parts of the two adjacent link bodies with radial play.
  • an outwardly widening conical extension is expediently provided on the hinge bolt at one end and a conical hole corresponding to this conical extension is provided in the bore of an end part of a link body, the conical bore advantageously being a conical inner bore a holding sleeve inserted in an end part of the link body is formed.
  • the collars arranged on the outside have centering shoulders for the articulation pin.
  • Fig. 1 '2 show a side view
  • Fig. I a plan view of a starter bar in a schematic representation
  • Fig. 3- represents a section along the line III-III of Fig. 2
  • Fig. 4 illustrates the process of releasing the starting head from the starting line.
  • the starting head is designated by 1, which is connected by means of a transition link body 2 to a link chain 3 which is composed of further link bodies 4 which are connected to one another in an articulated manner.
  • Two adjacent link bodies 1, 2, 4 each have comb-like intermeshing end parts 5, 6.
  • One of the limb bodies, etc. the one on the first limb body, the start Head 1, adjoining transition member body 2, has at its end parts 6 laterally projecting, against the end parts 5 of the start head 1 collars 7.
  • These bundles 7 are formed by bushes 8 inserted into the end parts of the link body, the length 9 of which is greater than the thickness 10 of the end parts 6.
  • Each of the bundles 7 projects into a recess 11, which is provided on each of the end parts 5 of the starting head 1 are.
  • These recesses 11 are U-shaped in cross section and open toward the top 12 of the start-up line.
  • the bundles 7 lie on support surfaces 13, which are provided at the base of these recesses 11, in the end parts 5 of the starting head, so that there is no or almost no play in the longitudinal direction 14 of the starting strand.
  • the intermeshing end parts 5, 6 of the two adjacent link bodies 1, 2 have mutually aligned bores 15, 16, the bores 16 penetrating the sleeves 8 centrally.
  • a hinge pin 17 is inserted, which has a radial clearance 18, 19 compared to the bores 15, 16.
  • One end 20 of the hinge pin 17 is tapered towards the end for easier insertion into the bores 15, 16; the other opposite end 21 of the hinge pin has a shoulder 22 which widens conically towards the end 21 of the hinge pin 17.
  • the hinge pin fits into a conical inner bore of a holding bush 23 inserted at a lateral end part of the start-up head 23 on, which, however, to allow easy loosening of the hinge pin, only extend over a short length 25 of these bushings.
  • the hinge pin 17 is to be loosened by hitting and then axially pulled out of the bores 15, 16, which can be done easily by hand, since the hinge pin 17 only rests on the two centering lugs 24 and on the holding bush 23 with friction.
  • the starting strand can be easily detached from the starting head 1 by moving the starting strand approximately perpendicular to the upper side 12, the bundles 7 sliding out of the recesses 11. During this separation process, there is only a line contact between the collars 7 and the recesses 11, so that the frictional forces that occur are only slight and cannot hinder the separation process even after prolonged use of the starting strand.
  • the hinge pin 17 itself does not need the starting strand. absorb forces as tensile forces when pulling out of the strand guide; these are transferred from the bundles 7 of the link body 2 to the starting head 1.
  • the hinge pin 17 only has the function of preventing the inadvertent removal of the starting head 1 from the link body 2.
  • Fig. 4 the separation process of the starting strand from the starting head is illustrated.
  • the start-up line is conveyed onto a rocker 26.
  • the start head 1 is still connected to the cast strand 27 during this process, it being assumed that the connection between the start head 1 and the cast strand 27, although it is a permanent start head, cannot be broken due to a defect.
  • the hinge pin 17 is knocked out and the rocker is pivoted from the position A shown in full lines in FIG. 4 into the position B shown in dash-dotted lines.
  • the collars 7 slide out of the recesses 11, so that the cast strand 27 undisturbed along the roll transition can be discharged in the direction of arrow 29 and 28 of the casting g Anfahrstran not further obstructed.
  • the easily removable hinge pins 17 and the bundles 7 sliding out of the start head thus make it possible to separate the cast strand from the start strand without a flame cutting device for the cast strand being required in front of the rocker 26 receiving the start strand (or other lifting device for the start strand).
  • the flame cutting device can be provided after the device 26 receiving the start-up line, which results in shorter conveying paths for the start-up line.
  • connection of the starting head 1 shown in the drawing to the adjacent link body 2 can also be provided between any other link bodies 2, 4 of the starting line.
