Definitions

  • the invention relates to a continuous casting plant for slabs comprising a water-cooled casting mould which is releasably connected to a vertically movable lifting table so that the mould may be caused to oscillate, and a short, vertical bar guiding means arranged below the casting mould.
  • the invention is aimed at avoiding the described disadvantages and difficulties by creating a continuous casting plant for slabs in which an excellent oscillation of the mould and the lifting table, respectively, is obtained, and in which, at the same time, any displacements in relation to the adjoining vertical bar guiding means and secondary cooling zone are avoided.
  • This aim of the invention is achieved in a plant of the kind defined in the introduction, in that the lifting table is formed as a rectangular, closed, water-cooled, box-type frame which preferably in the middle of each of its narrow sides is provided with a vertical ledge engaging into guiding means fixed to the pouring platform and adjustable to be exactly vertical.
  • each ledge is guided without play on its three free sides by two pairs of rollers arranged one above the other and by a further roller arranged perpendicularly in relation to said pairs of rollers.
  • each two pairs of rollers and the rollers arranged perpendicularly to the pairs of rollers are arranged in common housing fixed to said pouring platform.
  • rapid connections for the supply of cooling water are provided between the frame and the mould, said rapid connections being formed by bushings of the frame and hollow pins of the mould.
  • the inner cross section of the frame is greater than the outer dimensions of the vertical bar guiding means arranged below the casting mould so as to permit the insertion and removal of the bar guiding means in vertical direction after the mould has been released from the frame.
  • FIG. 1 is a vertical sectional view of a lifting table or frame according to the invention, along the line [-1 of FIG. 2.
  • FIG. 2 is the ground plan for FIG. 1.
  • FIG. 3 is a vertical sectional view along the line lll-lll of FIG. 2, and in FIG. 3 also the lifting device is shown.
  • numeral 1 denotes the casting mould whichis indicated in broken lines.
  • the mould is releasably connected to the lifting table by means of keyed joints 3, 4, 5, 6 which may easily be released; the lifting table has the form of an oblong, closed frame 2 and is water-cooled.
  • the frame 2 comprises supply ducts 7, 8, 9, l0 and drains l1, 12 for the cooling water.
  • rapid connections 13, l4, 15, 16 which are formed by bushings in the frame 2 and hollow pins on the mould 1.
  • Further rapid connections 17, 18 are provided for the outflow of water flowing through conduits installed in the frame but not shown in the drawing. Owing to these provisions the mould l and the frame 2 are uniformly and effectively cooled so that no distortions will occur as a result of differential heat influences, and favorable conditions are created for an exact and accurate guiding of the frame.
  • Levers 19, 20 act upon the narrow sides of the frame 2. These levers are articulated to a lifting and shifting device 30 by means ofejoumals 22 and rods 28 so that the frame 2 is oscillated when the rotatory movement of the eccentric disc 35 is transferred to the frame via the crankshaft 34 in the direction indicated by the double arrow (FIG. 3).
  • the levers 19, 20 are hingedly connected to angle levers 24 which are pivotable around a common-connection shaft 23.
  • the angle levers 24 are fixed to 'a baseplate 27 via an articulately mounted prestressed spring member 26.
  • Numeral 25 denotes a further baseplate for the connection shaft 23.
  • the lifting and shifting device 30 comprises a spindle 31, a nut 31' and a driving motor 32.
  • This driving motor serves to move the spindle 31 and to shift the nut 31 towards the right-hand side so that the crankshaft 34 which is hingedly connected to the nut 31' assumes the position 34' which is indicated in broken lines. This position corresponds to the lift minimum.
  • Numeral 29 denotes a connection shaft and numerals 33 and 36 denote baseplates.
  • the frame 2 is guided by means of two ledges 37, 38 which are arranged on the narrow sides of the frame 2 and are each engaged on two sides by pairs of rollers 41, 42; 43, 44 and 45, 46; 47, 48, respectively.
  • the ledges 37,38 are very narrow so that even the smallest expansions caused by heate.g. by changes of the cooling water temperature-cannot affect the precision of the lifting movement.
  • rollers 49,50 are provided which are arranged perpendicularly to the above-mentioned pairs of rollers to engage the ledges 37,38; the ledges are thus guided by rollers from three sides.
  • All rollers may be reset so that despite the fact that the ledges 37,38 will be worn the frame will always be accurately guided.
  • the rollers are mounted in sheet housings 51,52 which are connected to the steel construction 53 of the pouring platform or supported by crosspieces 54,55.
  • the ledges 37,38 are fixed to the bearing plates 39.40 which in turn are releasably connected with the frame 2 so as to permit the exchange of worn ledges.
  • a continuous casting apparatus for slabs comprising a lifting table arranged on a pouring platform said guiding means for each ledge comprising a set of adjustable rollers for play-free engagement of said ledge on its three free sides in a vertical direction, a water-cooled casting mould releasably connected to said lifting table, said lifling table being designed as a rectangular, closed, water-cooled, box-type frame having oppositely disposed vertical ledges mounted in engagement with guiding means supported on said pouring platform and adjustable to be exactly vertical said guiding means for each ledge comprising a set of adjustable rollers for play-free engagement of said ledge on its three free sides.
