Definitions

  • the invention relates to a device for continuous casting of metals, in particular of steel materials, to long products in a multi-strand casting, with several continuous casting molds, which are each stored separately in an oscillating drivable oscillating frame in the casting, arranged by means of both sides of the cast strand leaf spring pairs, the extending transversely to the casting direction, is mounted for guidance and weight compensation on a foundation frame.
  • a device for continuous casting of steel which consists of a casting mold oscillating in the casting direction, which is mounted transversely to the casting direction extending, clamped at both ends clamped and connected to a fixed to a support frame, designed as a servo hydraulic cylinder Oszillatlonsantrieb.
  • the servo-hydraulic cylinders are arranged in a laid-by the continuous casting mold longitudinal side plane laterally adjacent to the continuous casting mold with the support frame firmly connected, the continuous casting mold is attached to the springs in one point and the free ends of the springs are in firm connection with the support frame.
  • it is a so-called resonant mold, in which the spring force is adjusted to the mass of the mold such that the device oscillates in the resonance range.
  • the present invention relates to so-called multi-strand casters, in which several casting strands are produced side by side at the same time.
  • multi-strand casters efforts are made to minimize the strand spacing from cast strand to cast strand, i. from mold center to mold center.
  • the costs are thereby reduced and, in the case of conversions of existing plants, changes can still be made subsequently.
  • a stirring coil which influences the liquid core of the cast strand, can subsequently also be installed.
  • the invention is based on the object, even in so-called.
  • Resonant molds which are referred to at the beginning and whose essential feature is leaf spring packages to achieve structurally least possible strand spacing between the casting strands.
  • the stated object is achieved in that in the initially described device on an elongated foundation frame In Strand running direction two successively arranged, formed in the form of compact flat boxes housing are fixed, in which run upper and lower leaf spring pairs transverse to the strand direction and that attack on the leaf spring pairs Oszillationsantriebe, wherein a front oscillating drive to the rear oscillating drive operates synchronized.
  • the advantage is in such a transverse arrangement by crossing the cast strand or the strand running direction relative to the previous longitudinal arrangement a significant space and space savings, so that the distance from cast strand to cast strand, can be kept as small as possible.
  • the sequential arrangement of the flat boxes with the oscillating drives in the casting direction in a crossing transverse course of the leaf springs, transverse to the strand running or strand, allows to create a sufficiently large space for the continuous casting mold to be installed between the two flat boxes. At the same time sufficient space for the installation of the so-called. Zero support roller segment is obtained. Almost the entire strand spacing "A" can be exploited.
  • the front oscillation drive is set to the rear oscillation drive for a curved course of the casting strand with different strokes.
  • the rear oscillating drive is to be set to a higher stroke compared to the front oscillating drive.
  • oscillating drives consist of hydraulic drive units.
  • the oscillation drives can be arranged in protected areas below the foundation frame.
  • the flat boxes consists of two in line running direction behind one another rectangular frame for each two leaf spring pairs with the height spaced leaf springs and that between the rectangular frame Kokillenauflage a frame is arranged swinging.
  • 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 casting strand below the two rectangular frame and between longitudinal beams of the foundation frame. In addition to the protected position, the fastening points are thereby advantageous,
  • the suspension elements consist of a rotatably mounted on the longitudinal beams, two-armed levers with formed at one end of the lever attachment trough and connected to the other end of the lever Justiermittein.
  • the design of the device is further developed in that a water chuck 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 backwards away from the cast strand.
  • a multi-strand caster ( Fig. 1 ) with a plurality of casting strands 3 running parallel in the casting direction 1 for the casting strands by a continuous casting mold (not shown) and support roll scaffolds in segmental shape (not shown) are for long products such as billets, bloom (pre-block), round or profile cross sections, the continuous casting molds einzein arranged side by side.
  • Each of the continuous casting molds is stored separately in an oscillatingly drivable oscillating frame 2 in the casting direction 1.
  • a swing frame 2 is by means of leaf springs 4 ( Fig. 2 ) is connected to the continuous casting mold or the mold table. The oscillatory movements take place in the casting direction 1 as a sinusoidal movement.
  • the oscillation frequency and the oscillation height are coordinated.
  • the leaf spring pairs 4a and 4b extend transversely to the casting direction 1, crossing the cast strand 3, and serve for guidance and for Gewiohtskompensation on a foundation frame fifth
  • each foundation frame 5 is executed in strand direction 1 as an elongated rectangle.
  • the foundation frame 5 is formed in each case from longitudinal bars 5a and 5b.
  • each flat box 6 which extends transversely to the cast strand 3 in its longitudinal extent and bridges the gap between the two longitudinal bars 5a and 5b.
  • Each flat box 6 consists of a closed housing 6a, wherein a rear flat boxes 6b and a front flat box 6c is formed with the required distance for installation of a continuous casting mold.
  • the leaf springs to be described in more detail 4 are on the base frame 8, of which two are in each case parallel and spaced, the leaf springs to be described in more detail 4 as upper and lower leaf spring pairs 4a and 4b transverse to the strand direction 1, joints forming attached.
  • a water tensioning plate 9 is provided for cooling the continuous casting mold with a cooling medium feed 10 formed from below.
  • each Flachkestens 6 Is with open housings 6a, ie with removed protective cover 7 in Fig. 2 represents.
  • Each flat box 6, ie always two pairs of upper leaf spring pairs 4a and lower leaf spring pairs 4b is associated with an oscillating drive 11 which is fastened via a connection bridge 12.
  • the resulting front oscillating drive 11 a and the rear oscillating drive 11 b are synchronized and thereby cause unequal strokes but the same frequency a curve course.
  • the oscillation drives 11 a and 11 b are designed for example as hydraulic oscillation drive units 14 and therefore via hydraulic lines 15 fed.
  • a flat box 6 of two in strand direction 1 ( Fig. 1 ) arranged one behind the other, parallel rectangular frame 16 for each leaf spring pair 4a, 4b formed with height-spaced leaf springs 4 and between the rectangular frame 16 each a mold support frame 17 is arranged swingably.
  • Each of the mold support frames 17 carries two mold support surfaces 18 disposed in the ends.
