Definitions

  • the invention relates to a device for the continuous casting of metals, in particular steel materials, into long products in a multi-strand casting installation, with a plurality of continuous casting molds, each of which is mounted separately in an oscillating frame which can be driven in an oscillating manner in the casting direction and which has leaf spring pairs arranged on both sides of the casting wire , which extend transversely to the casting direction, is mounted on a foundation frame for guidance and weight compensation.
  • EP 0 468 607 B2 discloses a liquid-cooled mold for the continuous casting of metals, with which billet, bloom and round strands are cast by means of a tubular mold.
  • the mass of the mold for the individual strand formats is taken into account and it is found that for slab formats the weight of the mold is approx. 30 1 and the weight of a mold for round and rectangular strands is 1, 3 to 2.5 1.
  • the proposal then deals with the reduction of the mold weights in order to achieve higher vibrations with the least possible power consumption.
  • the present invention relates to so-called multi-strand casting plants in which a plurality of casting strands are produced side by side at the same time.
  • multi-strand casting plants efforts are made to achieve the smallest possible strand spacing from the casting vein to the casting vein, that is to say from the center of the mold to the center of the mold.
  • a stirring coil that influences the liquid core of the casting strand can be retrofitted.
  • the invention is based, to achieve structurally the smallest possible strand spacings between the casting wires even with so-called resonance molds, which are designated at the beginning and whose essential feature is leaf spring packages.
  • the object is achieved according to the invention in that, in the device described at the outset, two housings arranged one behind the other and in the form of compact flat boxes are fastened on an elongated foundation frame in the direction of the strand, in which upper and lower leaf spring pairs run transversely to the casting line and that on the Leaf spring pairs attack oscillation drives, whereby a front oscillation drive works synchronized to the rear oscillation drive.
  • the advantage of such a transverse arrangement by crossing the casting strand compared to the previous longitudinal arrangement is a considerable space and space saving, so that the distance from strand to strand can be kept as small as possible.
  • the arrangement of the flat boxes with the oscillation drives one behind the other in the casting direction with a crossing transverse course of the leaf springs, transversely to the strand axis or strand vein, makes it possible to create a sufficiently large space for the continuous casting mold to be installed between the two flat boxes. At the same time, enough free space is gained for the installation of the so-called zero support roller segment. Almost the entire strand spacing "A" can be used.
  • the front oscillation drive is set with different strokes in relation to the rear oscillation drive for an arc of the casting strand.
  • the rear oscillation drive must be set to a higher stroke than the front oscillation drive.
  • the oscillation drives consist of hydraulic drive units.
  • the oscillation drives can be arranged in protected rooms below the foundation frame.
  • the flat box consists of two rectangular frames, one behind the other in the direction of the strand, for two pairs of leaf springs each with leaf springs spaced apart in height, and that a mold support frame is arranged so as to be oscillatable between the rectangular frames.
  • the two rectangular frames for the mold support frame simultaneously form a guide.
  • the special protection for the drives is achieved in that the oscillation drive units are each arranged in the center plane of the strand vein below the two rectangular frames and between the longitudinal bars of the foundation frame. In addition to the protected location, the attachment points are advantageous.
  • suspension elements for the suspension of a support roller segment are mounted in the foundation frame between the longitudinal bars. This favors installation prior to assembly of the continuous casting mold.
  • the suspension elements consist of a two-armed lever, which is rotatably mounted on the longitudinal bars, with a suspension trough formed on one lever end and adjustment means connected to the other lever end.
  • the design of the device is further developed in that a water clamping plate for supplying the continuous casting mold with cooling medium is arranged on the rear flat box and that the cooling medium supply and the cooling medium discharge run away from the casting strand to the rear.
  • a water clamping plate for supplying the continuous casting mold with cooling medium is arranged on the rear flat box and that the cooling medium supply and the cooling medium discharge run away from the casting strand to the rear.
  • FIG. 1 shows a perspective view of the device in overall view
  • FIG. 2 shows the perspective view according to FIG. 1 without protective covers
  • FIG. 3 shows a side view in the plane without the first casting strand
  • FIG. 4 shows a top view of the device
  • Fig. 5 is a front view against the device when removed
  • Protective cover and Fig. 6 is a bottom view against the device.
  • FIG. 1 In a multi-strand casting plant (FIG. 1) with a plurality of casting strands 3 running in parallel in the casting direction 1 for the casting veins, each of which is formed by a continuous casting mold (not shown) and supporting roller stands in segment form (not shown) are for long products such as billets, Bloom (Bloom), round or profile cross-sections, the continuous casting molds individually arranged next to each other.
  • Each of the continuous casting molds is mounted separately in an oscillating frame 2 which can be driven to oscillate in the casting direction 1.
  • a swing frame 2 is connected to the continuous casting mold or the mold table by means of leaf springs 4 (FIG. 2).
  • the oscillating movements take place in casting direction 1 as a sinusoidal movement.
  • each foundation frame 5 is designed as an elongated rectangle in the direction of strand 1.
  • the foundation frame 5 is in each case formed from longitudinal spars 5a and 5b.
  • each flat box 6 which extends transversely to the casting line 3 in its longitudinal extension and bridges the gap between the two longitudinal bars 5a and 5b.
  • Each flat box 6 consists of a closed housing 6a, a rear flat box 6b and a front flat box 6c being formed with the required spacing for installing a continuous casting mold.
  • Each flat box 6 forms the housing 6a together with protective covers 7 on both sides.
  • the base frame 8 two of which are parallel and spaced apart, the leaf springs 4. to be described in more detail as upper and lower leaf spring pairs 4a and 4b transverse to the direction of strand 1, forming joints, attached.

  • each flat box 6 is shown in FIG. 2 with the housings 6a open, ie with the protective cover 7 removed.
  • the resultant front oscillation drive 11 a and the rear oscillation drive 11 b are synchronized and thereby cause an arc shape 13 when the strokes are the same but have the same frequency.
  • the oscillation drives 11 a and 11 b are designed, for example, as hydraulic oscillation drive units 14 and are therefore via Hydraulic lines 15 fed.
  • a flat box 6 is made up of two parallel rectangular frames 16 lying one behind the other in the strand running direction 1 (FIG. 1), each for a leaf spring pair 4a, 4b with leaf springs 4 spaced apart in height formed and between the rectangle frame 16, a mold support frame 17 is arranged to swing.
