Definitions

  • the invention relates to a device for the continuous casting of steel, consisting of a continuous casting mold that oscillates in the casting direction and is held in a lifting table and at least one oscillation drive acting on the lifting table.
  • Hydraulic oscillation drives for lifting tables are from the prior art Continuous caster known, the mold oscillation with any speed curves allow, for example, according to an asymmetrical Sinusoid.
  • the technical background for influencing the oscillation movement of the lifting table and thus the mold is the lubrication time extend between the mold wall and the strand skin and the To optimally design negative strip time.
  • an oscillation device for a continuous casting mold is from the prior art known with a so-called parallelogram lever system.
  • On one Warehouse stands are pivoted parallel to the handlebars that connect the mold table with the Wear a mold.
  • Servo hydraulic cylinders are used to oscillate the continuous casting mold intended.
  • the servo cylinders are anchored in place with their base plate and articulated with its piston rod to the mold table. The side shift the mold table becomes an elastic connecting element balanced.
  • a disadvantage of the parallelogram lever system is the high space requirement for it Installation of such an oscillation device in existing continuous casting plants is required.
  • the object of the invention is therefore to create a continuous caster of the type mentioned, with who can drive almost any speed curve of the lifting table and that is both compact and compact
  • the task at a facility of the type mentioned solved in that the lifting table with extending below its table level Guide blocks is formed, between which a stationary clamping block is arranged, and along the mold narrow sides below the table level both sides of the clamping block between or in this and that to it adjacent guide block at least two individual, one above the other, compliantly soft leaf springs in each other as well as in relation to the respective at the opposite leaf springs arranged parallel leaf springs in a parallel position are clamped.
  • the mold table can, for example, consist of two arranged on the mold narrow sides, U-shaped saddle bars that are parallel to the mold broadsides trusses are interconnected, exist.
  • the down In this case, pointing legs of the saddle carrier form the guide blocks of the Lift table, in the middle of which the stationary clamping block is arranged.
  • the saddle carrier can be designed with the U open at the top and upright upstanding legs, i.e. provide the other way round; the saddle carrier on one spanning fixed support frame could the hydraulic cylinder of the Oscillation drive can then be arranged hanging.
  • a preferred embodiment of the invention provides that the oscillation drive There are four hydraulic cylinders, two on each side of the mold arranged and with one end on the guide blocks and with the other End are attached to a stationary support frame. So possibly occurring different frictional forces on the mold sides over the preferably position or force-controlled hydraulic cylinders can be intercepted. moreover can with two cylinders arranged on each side a clean and achieve controlled lifting table movement because the forces or moments of force always are in equilibrium and are not due to the spring pairs made of individual leaf springs to be commuted.
  • the support frame serves both as Fixed storage for the hydraulic cylinders as well as the clamping blocks.
  • the entire The system is thus fixed in a single, fixed position relative to the oscillating lifting table Frame stored.
  • the Hydraulic cylinders and the clamping blocks each on different, however fixed storage areas are arranged.
  • the hydraulic cylinders are in one cross-sectional planes placed by the guide blocks to the side of the guide blocks arranged.
  • the hydraulic cylinders are with a End at a lower section of the guide block and the other end attached to the fixed support frame above this linkage.
  • the lifting table designated overall by 1, consists of on the narrow sides of the in 1 not shown mold arranged U-shaped saddle bars 2, the two guide blocks 3.1, 3.2 and one running horizontally in table level 4 Narrow side cross member 5 are formed.
  • a clamping block 7 is located in the middle between the guide blocks 3.1 and 3.2 is anchored on a foundation support 8.
  • Two, one above the other, thin leaf springs are as leaf spring pairs 9.1, 10.1 and 9.2, 10.2 on the Clamping block 7 attached.
  • Each leaf spring 9.1, 9.2 or 10.1, 10.2 is on one side with the guide block 3.1 or 3.2 and on the other side on the stationary Clamping block 7 attached.
  • the main difference of the embodiment of FIG. 2 is that the Clamping block 7 and the hydraulic cylinders 14.1, 14.2 do not have their abutments Foundation supports, but find in a unitary support frame 18, the one hanging arrangement of the lifting table allowed.
  • the Bearing flanges 12.1, 12.2 for receiving the piston rods 13.1, 13.2 (see. Fig. 1) in The embodiment shown is arranged at the bottom of the guide blocks 3.1, 3.2.
  • the support frame 18 has one through the guide blocks 3.1.3.2 laid cross-sectional plane upwardly extending support arms 19.1, 19.2, which are in each case delimited above by transverse legs 21.1, 21.2.
  • the hydraulic cylinders are articulated via their cylinder bottoms attached.
  • the bottom open U-shaped saddle carrier and the fixed support frame in the drawing plane 2 folded upwards by 180 °, i.e. in reverse order with upwards open U the saddle carrier and this bridging support frame 18 is provided become; in this case the cylinders hang from the fixed support frame.
