Definitions

  • the apparatus according to the invention applies essentially to the preparation of metallic tubular products, in particular cast iron tubes of circular section, but said apparatus can also be used for the preparation of other products of elongated shape.
  • tubular products can be produced using an upward continuous casting technique.
  • Such a technique is for example described in patent FR-A-2 352 612, on the basis of which the preamble of claim 1 is formed; in this patent the tubular product is obtained by continuous casting; liquid iron exiting from bottom to top of an ingot mold, subjected to pressure, enters a cylindrical enclosure in which it is calibrated, using a magnetic field, and cooled, and the solidified tubular product is drawn towards the high while the base of said enclosure is continuously supplied by liquid iron.
  • the technical problem consists in using an apparatus capable of pulling, in optimal conditions, upwards the elongated (tubular) product thus obtained.
  • Patent FR-A-2 375 936 discloses a device for horizontal extraction, step by step, of an ingot from an ingot mold, of the type comprising a body, capable of moving along the axis of the ingot to extract, in which jaws, in contact by their internal face with the external face of the ingot to be extracted, are connected to the body of the device by return members elastically mounted and producing a force in the opposite direction to that of the extraction of the ingot, the jaws being in contact by their external surface with rollers, perpendicular to the axis of the ingot, bearing on corners situated on the internal face of the body of the device.
  • this device provided for the horizontal extraction of an ingot from an ingot mold, is not applicable to the ascending vertical extraction of a long product from an ingot mold.
  • the use of return members provided with elastic means means that the jaws are not immediately released from the ingot when the extraction device returns to its starting position, since it is necessary to reach a certain compression ratio of said elastic means so that the jaws no longer clamp the ingot to be extracted.
  • a tube 1, of axis XX ′ is produced by continuous vertical ascending casting in a mold 2 from which it is extracted vertically upwards.
  • the mold itself is surmounted by a device making it possible to shape, calibrate and cool to a sufficient degree the elongated article (tube) so that the level 2 ′ represents the upper exit surface of this together.
  • the rise of the ring 6 from a height h causes, by wedging the balls 5 of the ring 6 between the outer surface of the tube 1 and the internal frustoconical surface of said ring 6, the rise of the tube 1.
  • the ring 6 descends, which provides a release of the balls 5 from this ring 6, while the balls 5 from the ring 3 then prevent the descent of the tube 1 to 1 inside the mold 2.
  • a new cycle can begin when the ring 6 has returned to its starting position.
  • This device therefore allows a step-by-step extraction of the tube 1 from an ingot mold 2 in an ascending vertical continuous casting process.
