Definitions

  • the invention relates to a continuous casting plant for steel with an oscillating continuous mold and at least partially curved support guide for the strand, the support guide following a first zone of the support guide being fastened to a machine base frame
  • first zone of the support guide is held by a carrier attached to the machine base frame and sliding against the mold.
  • the support guide following the first zone is also attached to the machine base frame.
  • the mold and the first zone can be removed upwards. Repairs to the moving parts of the oscillation mechanism, such as bearings of the steering lever or mold saddle, must be carried out in the system itself or by removing several bearing bolts of the handlebars that determine the oscillation movement. Such work is time-consuming and increases the downtime of such systems.
  • the aim of the invention is a continuous caster which overcomes the disadvantages mentioned and in which both individual machine parts, such as a mold with or without a first support guide zone, and an entire machine group, consisting of mold, first support guide zone, mold table and oscillation support, are quickly removed from one unit - and can be installed again. Furthermore, this continuous caster should be precisely aligned at the transition points between the mold and the first zone or between the first zone and the subsequent zone when the machine is hot and cold.
  • this object is achieved in that an upper section of the machine base frame and a support frame for the mold and the first zone of the support guide are arranged at least partially overlapping and on their undersides each is supported on a common foundation for both and that the upper section of the machine base frame in the upper end region and the support frame for the mold are movably supported at a common support point in the strand running direction.
  • the continuous caster according to the invention allows in one Failure trap, such as breakthrough, the removal of the mold with or without the first zone. Without significant additional work, however, all elements of the oscillation mechanism and the mold table can be removed and overhauled in the workshop. If there are appropriate replacement sets, repair work on the oscillation mechanism can be carried out without significant downtimes of the system.
  • Another advantage of this construction is that the clearly defined attachment points, both of the support frame for the mold and the first zone, as well as the upper section of the machine base frame ensure dislocation-free transitions in the strand guide, so that such continuous casting plants are also suitable for casting sensitive steels are.
  • the support at the common support point can be selected in various ways.
  • a preferred solution is seen according to a feature of the invention in that the upper section of the machine base frame is connected in its upper end region to the support frame for the mold via sliding block guides movable in the direction of the strand and that the common support point is provided with further sliding block guides arranged on the raised foundation.
  • the upper section of the machine base frame is supported indirectly via the support frame at the common support point.
  • the upper section of the machine base frame and the support frame can be individually supported directly on a concrete foundation.
  • the invention proposes to pivotally support the upper section of the machine base frame and the support frame for the mold on the undersides of the foundation on axes arranged transversely to the strand running direction and parallel to the curved support surfaces of the strand web.
  • the invention recommends that the swivel axes provided as foundation parts on the upper section of the machine base frame and on the support frame are aligned with one another.
  • the arrangement of a common swivel axis represents an economical and precise solution for a foundation design. Instead of a direct arrangement of the swivel axis on the foundation, they can advantageously be supported indirectly on the foundation via the machine base frame.
  • the invention recommends that they be articulated at both ends and arranged at approximately the same height. This results in a statically clearly defined bracket of high accuracy.
  • 1 and 2, 3 shows an oscillating continuous mold of a continuous casting plant for steel.
  • the mold sits on a mold table 4 which is connected on each side via two links 5 and 6 to a support frame 7 for the mold 3 and a first zone 10 of the support guide, which frame is attached to the outside of the curved support guide.
  • 1'-e oscillation path of the mold 3 is determined by the pivoting movement of the links 5 and 6.
  • the link 6 is connected via an extension to a drive lever 9 of the oscillation drive.
  • the first, fixed support guide zone 10 is suspended from the support frame 7 by means of supports 11 and guided relative to the mold 3 via slide guides 13 attached to the mold table 4.
  • the support guide segments 14 following the first support guide zone 10 are fastened to an upper section 15 of a machine base frame 16 or to the machine base frame 16 itself.
  • the machine base frame 16 is supported on a foundation 19 via axes 18.
  • the support frame 7 and the machine base frame 16 each consist of two interconnected side walls.
  • the support frame 7 and the upper section 15 of the machine base frame 16 are likewise pivotable on an axis 22 arranged transversely to the strand running direction 20 and parallel to the curved support surface of a strand track 21 supported bar. It is immaterial to the invention whether the support frame 7 and the upper section 15 of the machine base frame 16 rest directly or indirectly on the foundation 19 via the machine base frame 16.
  • the axes 22 are provided continuously for the support frame 7 and for the upper section 15 of the machine base frame 16.
  • separate axes for the support frame 7 and the upper section 15 of the machine base frame 16 are also conceivable, which are arranged approximately in alignment with one another. Instead of the axes 22, other rigid or pivotable support devices can also be used.
  • Anchor rods 23 connect the support frame 7 and anchor rods 24 connect the upper section 15 of the machine base frame 16 to a common support point 17 which has support points 25 and 26 which are raised from the foundation.
  • the support frame 7 and the upper section 15 of the machine base frame 16 are thus mutually independently connected to the foundation.
  • the links 5 and 6 are attached to the outside of the arched support guide. But it is also possible to mount the support frame 7 and the upper section 15 of the machine base frame 16 on the inside of the arcuate support guide. Alternatively, this guide concept can be used for the oscillation movement of the mold, but also for straight molds and subsequently only partially bent support guides. Instead of the oscillation guide shown in this example by means of links 5, 6, other known oscillation guides and oscillation drives can also be used.
  • the support points 25 and 26 attached to the raised foundation can also be attached to a correspondingly strong, vertical support beam of the machine or hall structure. It is essential that all anchor rods are articulated to the common support point 17, so that there is no relative movement between the support point 17 or the support points 25 and 26.
  • the mold 3, the first zone 10, the mold table 4 or the support frame 7 can be exchanged either as a complete exchange unit or as individual parts. Also, only the mold 3 and the first zone 10 can be removed and reinstalled together.
  • a crane suspension 31 is advantageously used to remove the entire exchange unit.
  • the anchor rods 23 and the link 6 are designed at their ends for rapid engagement and disengagement of the connecting bolts 32 and 33, respectively.
  • the oscillation lever 9 is held in the working position, for example, by a spring 35.
  • a force device (not shown) can be used to press against the force of the spring 35.
  • a common change of the parts mentioned by means of the crane suspension 31 can take place in 3 to 5 hours, for example.
  • FIG. 3 shows a further example of a fastening of the upper section 15 of the machine base frame 16 in the upper end region and of the support frame 7 for the mold 3 the common base 17 shown.
  • the mold, first support guide zone and support guide segment have been omitted from FIG. 3.
  • the common support point 17 consists of a bracket 30 attached to the raised foundation or to a steel frame, to which a sliding block 34 is articulated.
  • This sliding block 34 interacts with the support frame 7 so that it can expand and contract freely between its two attachment points when the temperature changes.
  • the two frames 7, 15 are movable in the strand running direction at the common support point 17 and are supported without play transversely to the strand running direction.
  • the upper section 15 of the machine base frame 16 is supported indirectly via the support frame 7 by means of a further sliding block guide 36 at the common support point 17.
  • the sliding block guide 36 also allows an expansion movement in the direction of the strand.
  • the support frame 7 is generally longer than the upper section 15 of the machine base frame 16 and overlaps the upper section 15 with part of its length. This upper section 15 is usually overlapped in its entire length.
  • the two frames 7 and 15 are each individually supported on a foundation 19 common to both frames 7, 15, the axes 22 being considered as part of the foundation, although in the example shown they rest on the machine base frame 16.
  • the frame parts 7 and 15 could also be supported directly on the concrete foundation 19.
