Definitions

  • the apparatus according to the invention applies essentially to the preparation of metallic tubular products, in particular of 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 French patent 7616285 (published under the number 2 352 612); 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, by using a magnetic field, and cooled and the solidified tubular product is pulled upwards then that 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 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 be extracted, in which of the 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 mounted elastically and producing a force in the opposite direction to that of the extraction of the ingot, the jaw being in contact by their external face with rollers, perpendicular to the axis of the ingot, bearing on corners located 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.
  • the present invention therefore relates to an apparatus for the extraction step by step, from an ingot mold, of an elongated solid product obtained by continuous ascending casting, conformation, calibration and solidification in a suitable enclosure, said apparatus being characterized in that 'it consists : - a first fixed device, located in the immediate vicinity of the outlet orifice of said enclosure, consisting of a ring, surrounding said solid, having an internal face in the form of a truncated cone opening of between 10 and 20 ° and having its small base downwards, the space situated between the external surface of said solid and the internal face of said ring being provided with balls of several diameters capable of ensuring the jamming of said solid in the event of initiation of movement upstream of this solid; - And a second mobile device having the same structure as the first device and also comprising balls, this second device being driven in a longitudinal movement back and forth along the axis of said solid.
  • 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 apparatus according to the invention consists - a ring 3 located in the immediate vicinity of level 2 'and which can even be made integral with the ingot mold-forming-cooling device; this ring 3 has any external surface but internally has an internal face 4 of frustoconical shape; the opening of this frustoconical shape is oriented upwards (towards X ′), the small base of this shape therefore being towards the bottom of this ring; the shape of this internal face 4 is obviously adapted to the external shape and to the dimension of the tube 1, most often the truncated cone therefore has circular straight sections; the inclination of the frustoconical internal face of the ring 3 relative to the axis of the tube 1 (vertical) is between 10 and 20 ° and is preferably 15 °; the space between the internal face of the ring 3 and the external surface of the tube 1 is filled with balls 5 of several diameters, these balls are distributed, according to their size, in two or more successive beds, each bed being formed of balls of the same size which are
  • the operation of the apparatus according to the invention is as follows: the rise of the ring 6 from a height h causes by the jamming of 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. Once the extraction of the tube 1 carried out from a height h , 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 the inside of 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.
