Definitions

  • the invention relates to a device for continuous casting of metals, in particular of steel, by means of a continuous casting mold, which is mounted in an oscillating drivable in casting direction swing frame, the stroke of the oscillatory motion and / or the frequency are adjustable and the swing frame arranged symmetrically on both sides of the cast iron Spring packs for guidance and weight compensation is stored.
  • the invention has for its object to improve compared to simply rectangular slab cross-sections and casting into more complicated G devisqueritese.
  • the monitoring of the surface of the solidifying cast strand is carried out in such a way that a hydraulic drive is provided for the oscillating frame, to which a measuring device for determining the pressures in the drive cylinder is connected, due to which the frictional force between the cast strand and the continuous casting mold is calculated.
  • the strand surface can in principle be improved by the oscillation movement being variable by means of the drive in the oscillation stroke and / or in the frequency and / or in the oscillation curve.
  • the reduction of Friction can be calculated via calculation models and the values obtained can be entered into the control of the respective drive.
  • the frictional force can be influenced via the lifting height of the oscillatory movement of the oscillating frame.
  • the continuous casting mold operated in the resonance method can obtain a low frictional force value such that the lifting height of the oscillation movement of the oscillating frame can be adjusted to approximately 0.3-6 mm.
  • the storage of the continuous casting mold for the resonant oscillation method is designed to an effect that in a base frame at an acute angle to each other on both sides paired leaf spring assemblies are resiliently attached at both ends and that the continuous casting mold supporting swing frame means centrally between the ends of each on the Leaf spring packs and the swing frame attached and stored with these bearing blocks is stored.
  • This storage achieves the desired precise guidance with the lowest possible mass of the components.
  • the upper leaf spring packet pair is mounted horizontally extending horizontally or inclined base frame.
  • the continuous casting mold 1 is a device for continuous casting of metals, in particular of steel, by means of a continuous casting mold 1, which is mounted in an oscillating drivable in casting direction 2 oscillating frame 3, wherein the stroke of the oscillatory motion and / or the frequency are adjustable and the swing frame. 3 by means of leaf spring packets 4a, 4b arranged symmetrically on both sides of the cast iron; 5a, 5b is mounted for guidance and weight compensation.
  • the continuous casting mold 1 has a profiled casting cross-section 1a, wherein the leaf spring-mounted oscillating frame 3 is operated together with the continuous casting mold 1 in the resonant oscillation method.
  • a dog-bone mold is shown, with which starting material for double-T profile rails is cast.
  • a homogeneous surface without major errors is generated by the fact that the oscillation movement by means of a drive 6 in the oscillation and / or in the frequency and / or in the oscillation curve is variable.
  • This oscillatory movement can be transmitted by means of a hydraulic or an electric or electro-mechanical drive 6 on the swing frame 3.
  • the frictional force on the lifting height of the oscillatory movement of the swing frame 3 to influence, that is to keep as small as possible.
  • the frictional force and the surface quality can be influenced in particular by smaller lifting heights of the oscillatory movements, for example in the form that the lifting height of the oscillation movement of the oscillating frame is adjusted to about 0.3-6 mm.
  • the drive 6 engages the in Fig. 2, indicated on the left attack point 6a.
  • FIG. 2 The structure of the mold oscillation apparatus is shown in more detail in FIG. 2: in a base frame 7, leaf spring assemblies 4a, 4b, below and 5a and 5b extend at an acute angle to each other on both sides in pairs.
  • the drive 6 for the oscillatory movements consist of a hydraulic drive 9 with a drive cylinder 9a, the drive rod 9b penetrates the swing frame 3 with a screw and is stored in this.
  • the swing frame 3 is supported on a cross member 10 for the drive 6.
  • the leaf spring assemblies 4a, 4b and 5a, 5b are each clamped by means of a spring clamp 11 at their ends, which is clear in Fig. 2.
  • a base frame 7 carries the swing frame 3, which holds a bearing block 8 at a lower beam.
  • the swing frame 3 is connected via a lower plate 12 by means of bearing brackets 13 (each consisting of a screw, a threaded nut and a washer) with the base frame 7 while clamping the leaf spring assemblies 4a, 4b (5a, 5b).
  • the movement of the swing frame 3 is limited by a safety stop 14 down.
  • leaf spring assemblies 4a, 4b (on the other side 5a, 5b) are secured by means of a respective lower holding plate 15 and screw 16 on the base frame.
  • the arrangement of the leaf spring assemblies 4a, 4b is spatially completed by a respective guard plate 17. Furthermore, a centering rod 18 and lateral connecting screws 19 are present.
  • the leaf spring assemblies 5a, 5b are mounted by means of upper holding plates 20 and upper screw 21.
  • the upper bracket 8 by means of upper bearing brackets 22 and an upper stop 23 is provided.
  • a base frame part 24 is also provided for delimiting from the leaf spring package 5b. Furthermore, connecting elements 25 are visible.
