Definitions

  • the invention relates to a device for lifting and pivoting a metallurgical vessel, in particular a tundish arranged above a mold in a continuous casting plant, said device having a hollow vertical column, being liftable, lowerable and rotatable about its axis, to which column the vessel is secured and on which there acts a pivot drive actuated by a pressure medium.
  • a swivel drive comprises a cylinder and a piston hinged to two levers.
  • One of the levers is rigidly fastened to the column and the other lever is pivotable about a stationary axis.
  • the other lever has a guide rod hinged to it, which is pivotably secured to a follower that is rotatable relative to the column.
  • the hollow column may have the form of a cylinder with a pressure chamber and a piston forming the axis of the rotatable column.
  • FIG. 1 is a schematical side view of a liftable and lowerable, as well as pivotable, tundish of a continuous casting plant;
  • FIGS. 2 and 3 illustrate details of the lifting and swivel drive according to a first embodiment, i.e. FIG. 2 is a vertical section and a side view, respectively, and FIG. 3 is a pertaining horizontal section along line IIIIII of FIG. 2;
  • FIG. 4 is an illustration similar to FIG. 2 for a second embodiment of the invention.
  • a liftable and lowerable hollow column 1 is rotatable in a bearing 6 of a casting platform 7. It carries a refractorily lined tundish 2 with a casting tube 3. The tundish is also displaceable horizontally by means of a mechanism not illustrated in detail.
  • the axis of the casting tube 3 is in alignment with the axis of a water-cooled continuous casting mold 4 oscillating in the vertical direction, and having a cavity or opening 5.
  • a cylindrical cavity or pressure chamber 10 that is closed on the top and open on the bottom, receives a stationary piston and rod 8, whose lower end is supported against a supporting plate 9.
  • the column 1 is lifted when the pressure chamber 10 (FIG. 2) is actuated by the injection of a hydraulic medium that applies a force between a pressure face 23 of the piston and an upper surface 24 of the pressure chamber.
  • a lever is secured, to which the piston rod 13 of a hydraulic cylinder 14 is hinged; the hinge bearing is denoted with 12.
  • the cylinder 14 is connected with a horizontal lever 16 via a further hinge bearing 15 and the lever 16 is pivotable about a vertical trunnion 17.
  • a hinge bearing 18- slightly offset is provided for a guide rod 19.
  • the guide rod 19 is connected via a swivel bearing 20 with a follower ring 21, which is freely rotatable about the column 1. In the operating position according to FIG.
  • the hydraulic cylinder 14 is actuated, so that the lever 11 may be pivoted about an angle of approx. in direction of the arrow 22.
  • the function of the device according to the invention results from the drawings as follows.
  • the tundish is to be lifted by the distance h, e.g. by 400 mm, from the operating position illustrated in FIGS. 2 and 3 by actuating the pressure chamber 10 with a pressure liquid. If the lever 16 were rigidly secured to the platform and no guide rod 19 were present, a pivot movement of the lever 11 would occur during the lifting phase, first in the direction of the arrow 22 and then in the direction of the arrow 22", back into the original position, whereby the casting tube 3 would move in direction of the wall of the mold 4 and back again.
  • the lever 16 is arranged to be pivoted about the vertical axis 17 and due to the arrangement of the guide rod 19, this pivot movement is, however, fully compensated.
  • the casting tube 3 does not change its position in relation to the mold walls and eccentric casting and/or breaking of the casting tube, while the tundish is being changed, is eliminated.
  • the axisof the guide rod 19 remains in a plane laid through the vertical axis of the column 1. Only the position of this plane changes slightly.
  • FIG. 4 is a schematic illustration of another solution according to the invention, which consists in that the lever 16 is arranged in a substantially vertical position and is pivotable about a horizontal axis 17', wherein the hydraulic swivel device (14, 13') is arranged above the guide rod 19.
  • Reference numerals 12, and, 18 denote hinge bearings and 20 denotes a swivel bearing.
  • the lever fastened rigidly to the column 1 on to which the swivel device (14', 13') is hinged, is denoted with 11 and the follower ring, freely rotatable about the column 1', is denoted with 21. Therefore, with this embodiment the pivot movements are also fully compensated, i.e. a deviation of the casting tube 3 is impossible.
  • the practising of the invention is of value not only in continuous casting plants, but also everywhere, where it is important to 'move pivotable construction units or vessels in an exactly vertical direction without actuating the swivel device.
  • a device for lifting and pivoting a metallurgical vessel, in particular a tundish arranged above a mold in a continuous casting plant comprising:
  • a swivel drive for rotating said vertical column about its axis, said swivel drive comprising a cylinder and a piston actuated by a pressure medium, one end of said swivel drive being hingeably connected to the other end of said first lever and the other end of said swivel drive being hingeably connected to the other end of said second lever;
