Definitions

  • the present invention relates to the vertical upward continuous casting of a spheroidal graphite cast iron pipe, without the use of a core to form the pipe cavity.
  • the invention relates more particularly to a device for supplying liquid iron to a tubular die giving the external shape of the pipe, either from a siphon block (source supply), or from a ladle. under low gas pressure.
  • the problem is posed of rotating a mass of liquid cast iron, at a speed lower than the centrifugation speed, with the aim of homogenizing and regulating the supply, inside a cooled tubular die. and fixed, giving the external shape of the tube to be generated, without the use of a core.
  • the problem is to maintain a permanent movement of rotation of the liquid iron in the fixed and cooled tubular die in order to regularize the thickness of the iron tube obtained on each circular section of this tube and thus obtain inner walls and completely concentric exterior.
  • the invention relates to a device for feeding a fixed tubular die, which solves this problem.
  • This rotary feeder of the invention of the type comprising a cooled die constituting a reservoir crucible for liquid cast iron, crucible from which a spheroidal graphite cast iron pipe must be generated, is characterized in that it comprises less at the lower part of the crucible-reservoir of the impulse or rotation means with a horizontal component of the speed of rotation of the mass of liquid iron contained in said crucible-reservoir.
  • said impulse or rotation means are hydraulic means.
  • the device of the invention is then characterized in that it comprises at the base of the crucible-reservoir at least one tangential inlet conduit for liquid iron which opens into the crucible-reservoir for liquid iron.
  • This tangential supply of liquid iron can be subjected to rhythmic pulsations which favor a slow rotation of the liquid iron.
  • These means for rotating can also be gaseous, with the use of a gaseous fluid chemically inert with respect to the cast iron (argon, nitrogen).
  • said means are magnetic.
  • the supply device of the invention is characterized in that it comprises magnetic means housed inside a hollow central relief providing, with the cooled die, an annular chamber of liquid iron, on a height greater than that of the annular volume of liquid iron, in order to create a magnetic field rotating around the axis of the die and of the central relief over the entire height of the annular mass of liquid iron.
  • the impulse or rotary drive means are mechanical.
  • the rotary feeding device of the invention is characterized in that it internally has a hollow central relief, in the axis and through the cavity thereof, a vertical rotating shaft carrying at its part upper vertical arms of refractory material immersed in the annular mass of liquid iron in order to cause it to rotate.
  • the invention is applied to the continuous ascending casting of a cast iron pipe T, said pipe being thin because the thickness / diameter ratio is low, less than 10%.
  • the thickness of the barrel, i.e. tubular part adjacent to the socket does not exceed 15 mm for a diameter of 1000 mm, 8 mm for a diameter of 300 mm and 5 mm for a diameter of 80 mm.
  • the mannequin M is introduced into the die 11 from above. While the die 11 is not cooled at its lower end, it is instead cooled over most of its height, to its upper end, by the cooling jacket 13.
  • the cast iron therefore solidifies at contact of the die 11, according to an increasing thickness up to the mannequin M in contact with which it solidifies and on which it is hooked by the notch Ml.
  • the mannequin M is then pulled upwards by rollers or rollers E for driving and guiding.
  • the rollers E driven by a stepping motor, cause the dummy M to rise in stages.
  • the mannequin M drives the solidified part of the iron upwards, step by step.
  • the temperature of the liquid cast iron contained in the crucible-reservoir 11-12 is homogenized and the thickness of the pipe T is regulated on the circular section of the barrel of the pipe T in training.
  • Said circular section therefore has perfectly concentric inner and outer walls.
  • the upward extraction of the solidified T pipe is carried out discontinuously, step by step, as described in patent application 84 00 382.
  • the barrel start of the T pipe lengthens with each printed climb stroke by the rollers or rollers E according to a constant thickness over the entire circular section of the barrel, thanks to the slow rotation due to the tangential supply of liquid iron by the vertical chimney 9 and the tangential orifice 18.
  • the homogenization of the bath temperature is to a certain extent linked to the regularization of the thickness of the barrel formed with slow rotation of the liquid iron due to the solidification process of the liquid iron: the iron is a eutectic liquid whose solidification is very different from that of steels: during solidification, cast iron does not undergo the phenomenon of segregation and does not comprise a solid and liquid mixture. Cast iron is a eutectic liquid which suddenly passes from the liquid phase to the solid phase, without mixing the two phases and without dendrite.
  • the Applicant has found that smaller thicknesses were obtained where the bath was warmer and greater thicknesses by homogenizing and regulating the temperature of the bath by rotation of the liquid iron. By this rotation it also obtains a more regular thickness on a circular section.
  • a central relief 34 blind at its upper part replaces the central relief 17 of FIG. 1. It comprises a cavity 35 for housing electromagnets or magnets 36 carried by a rotary shaft 37 of vertical axis XX which is that of the central relief 34 and of the crucible and reservoir 11-12. Inside the cavity 35, the magnets 36 and the shaft 37 are protected from any contact with the molten iron. The magnets 36 extend over the entire height of the mass of liquid cast iron F.
  • the rotary shaft 37 is rotated by a geared motor group 38.
  • Liquid cast iron is supplied by siphon block with vertical chimney 9, horizontal duct 7, opening at the lower part of the annular volume of liquid cast iron comprised between the central relief 34 and the die 11, possibly by a tangential orifice 18 as in fig. 1. But, in this case, due to the use of magnetic means such as electromagnets or rotating magnets 36, the tangential orifice 18 is optional.
  • the liquid iron supply duct can simply open out at the bottom 12 of the crucible-reservoir 11-12.
  • the barrel of the pipe T is formed in the same way as in the previous example of FIGS. 1 to 3 with the only difference that the liquid cast iron, from the start only comes from the siphon block with vertical chimney 9 and that the slow rotation of the liquid cast iron is carried out either only by the rotation of the electromagnets 36 or by the combined action of driving the electromagnets in rotation 36 and the tangential arrival of the liquid iron by a tangential orifice 18 if one is provided, as in FIG. 4.
  • Gaseous fluidic means for rotating the liquid iron at low speed in rotation can also be used according to different exemplary embodiments illustrated in FIGS. 6 to 11:
  • the liquid cast iron is supplied by siphon block 7-9-10.
  • the duct 7 opens out at the bottom 12 of the annular volume comprised between the central relief 17 and the die 11 by a non-tangential orifice 8.
  • an inert gaseous fluid such as, for example, nitrogen or argon is brought tangentially near the bottom of the annular volume of liquid iron comprised between the die 11 and the central relief 17.
  • the gaseous fluid for rotating the liquid iron is brought for example by two horizontal nozzles 45 mounted tangentially to the cylindrical cavity of the crucible-reservoir and to the cylindrical cavity 46 of the die 11, in the extension of the cylindrical internal wall of the die 11, in the mass of the base 6 and in the vicinity of the bottom 12.
  • Each of the two nozzles 45 comprises a plug or a porous frustoconical nozzle 47 mounted at the bottom of an orifice also frustoconical which opens tangentially into the cavity 46, the nozzle porous 47 being made of refractory material, for example silico-aluminous (a sort of rammed earth with a large particle size to have a suitable porosity), a cylindrical sleeve 48 of the same diameter as the large base of the porous nozzle 47, the sleeve 48 being made of material refractory and passing through the wall thickness of the base 6, coaxial with the nozzle 47, and, in the axis of the cylindrical sleeve 48, a conduit 49 for supplying gaseous fluid to the porous nozzle 4 7, the duct 49 being connected to a source of gaseous fluid under pressure, not shown.
  • a plug or a porous frustoconical nozzle 47 mounted at the bottom of an orifice also frustoconical which opens tangential
  • a closure plate 50 is applied on the outer end edge of the cylindrical sleeve 48 and on a boss 51 coming from the body with the base 6 or else attached to the latter.
  • the closing plate 50 is crossed by the conduit 49.
  • Variant of Fig. 8 the device for rotating the liquid iron F by a pair of tangential nozzles 45 for blowing an inert gaseous fluid, is the same as in FIGS. 6 and 7. The only difference is the mode of supply of liquid iron which is carried out by teapot bag 1 under gas pressure and pouring tube 4 vertical in the axis XX, as in FIG. 1. There is no siphon block. There is also no central relief 17, so that the volume of liquid iron F contained in the crucible-reservoir 11-12 is no longer annular but cylindrical, the bottom 12 no longer being annular itself . The frustoconical nozzle 5 and the upper edge of the ascending pouring tube 4 therefore open at the bottom of the tank 12 of the crucible-reservoir 11-12. The removal of the central relief 17 is justified when it comes to pouring a tube T of small diameter.
  • the central relief 17 can also be omitted to pour a tube T of small diameter.
  • the central relief 34 is essential to serve as a housing for an electromagnet 36 or more electromagnets 36 used to create a rotating magnetic field in the annular volume of liquid iron contained in the crucible-reservoir 11-12, over any the height of said crucible-reservoir.
  • the central relief 39 is also necessary in the example of FIG. 5 for the passage of the shaft 31 for rotating the refractory bars 44 for rotating the cast iron.
  • the injection nozzles 52 inject large gas bubbles into the liquid iron. But as the nozzles 52 open at the bottom 12 of the crucible-reservoir 11-12, instead of opening on the cylindrical wall of the crucible-reservoir 11-12, they reduce the friction of the liquid cast iron in rotation on the bottom 12. In addition , if the gas bubbles are injected at high speed, the kinetic energy for rotating the liquid iron is higher.
  • the level of liquid pig iron in the crucible-reservoir 11-12 can vary between an upper level N situated at the upper part of the die 11 and a lower level N1 situated below the level N, not far from the top of the die 11 ; these upper N and lower Nl levels in the die 11 correspond to the same upper N and lower Nl levels in the well 61 of the skimmer bag 58, by effect of communicating vessels through the orifice 63 and the pouring chute 64. On the other hand, these upper N and lower N1 levels in the die 11 correspond to a lower level N2 in the chamber 60 and an upper level N 3 which are different from N and N1.
  • a maximum gas pressure P1 is required while for obtain the lower level N1 in the die 11, corresponding to the upper level N3 in the chamber 60 of the pocket 58, a minimum gas pressure P2 is required.
  • the level of N2 to N is raised in the crucible tank 11-12, by introducing liquid iron following the arrow f into the well 61 of the skimmer bag 58.
  • the gas pressure in the chamber 60, via the conduit 32 is varied periodically and regularly between the maximum value P1 and a minimum value P2 while continuing to renew the liquid iron in the well 61 during step-by-step extraction.
  • a gas pressure pulse is made according to the sinusoidal curve of FIG. 14 which is a diagram of the variation in gas pressure P admitted by the conduit 32 into the chamber 60 as a function of time t.
