Definitions

  • the present invention relates to a continuous metal casting apparatus for casting tubes or the like.
  • the present invention mainly consists in a metal casting apparatus for casting tubes or the like, which apparatus includes mold means deining an upwardly extending annular space having a central axis and inner and outer upper edges and being adapted to receive molten metal.
  • Inner and outer annular molten metal supply means are provided for supplying molten metal to the annular space.
  • These supply means are arranged above the mold means, concentric with the annular space and rotatable about the above-mentioned axis, and the inner supply means has an outer peripheral portion adjacent the inner edge of the annular space Aand formed with opening means therethrough and the outer supply means has an inner peripheral portion adjacent the outer edge of the annular space and formed with opening means therethrough.
  • Fig. 1 is an elevational view, partly in section, of a preferred embodiment according to the present invention taken substantially along line I-I of Fig. 2;
  • Fig. 2 is a plan view of the embodiment illustrated in Fig. 1;
  • Fig. 4 is a plan view of the embodiment illustrated in Fig. 3.
  • a continuous casting apparatus which includes an outer substantially cylindrical mold member 1 and an inner cylindrical core member 2, which members together constitute a mold means and define between themselves an upwardlyextending annular space 3 which is adapted to receive molten metal.
  • a tube or the like may thus be continuously cast in the space 3 by maintaining the annular liquid level 4 of the molten metal substantially at the level indicated in Fig. l, in a manner well known in the art.
  • suitable cooling means (not shown) may be provided for cooling the members 1 and 2.
  • Inner and outer annular molten metal supply troughs 5 and 6 are provided for pouring molten metal into the space 3.
  • the troughs 5 and 6 are connected to each other by .a plurality of radial ribs 7, are arranged concentrically with the space 3 and are rotatable about the central axis thereof.
  • the arrangement of the parts is such that the inner trough 5 is arranged above and adjacent to the inner edge of the space 3 and the outer trough 5 is arranged above and adjacent to the outer edge of the space 3, as is clearly shown in the drawing.
  • the outer peripheral edge of the inner trough 5 has a diameter approximately equal to the inner diameter of the space 3 and is therefore substantially above inner edge thereof
  • the inner peripheral edge of the outer trough 6 has a diameter approximately equal to the outer diameter of the space 3 and is therefore substantially above the outer edge thereof.
  • Suitable drive means 8 are provided for rotating the troughs 5 and 6, so that both may rotate together about the central axis of the annular space in the direction shown by the arrows in Fig. 2.
  • a bifurcated supply trough 9 is arranged above ⁇ the troughs 5 and 6.
  • the free ends of the arms of the trough 9 are provided with bottom openings 10 and 11 which are arranged above the annular troughs 5 and 6, respectively, so that when molten metal is poured into the supply trough 9 by means of a ladle 12, shown fragmentarily in Fig. l, the metal may flow into the annular troughs 5 and 6.
  • the outer peripheral side wall portion of the trough 5 is provided with a plurality of inner opening means, three of which are shown at 13, 14 and 15.
  • These opening means may be constituted by slots or bores passing through the inner peripheral side wall and are angularly displaced from each other, as shown in Fig. 2.
  • the opening 13 is fashioned so that a stream of molten metal issuing therethrough will impinge upon the liquid level 4 in the region of its inner edge adjacent the core member 2, the opening 14 so that the stream of molten metal issuing therethrough will impinge upon the liquid level 4 in the region of its central annular portion, i. e., approximately midway between the members 1 and 2, and the opening 15 so that the stream of molten metal issuing therethrough will impinge upon the 'liquid level 4 in the region of its outer edge adjacent the outer mold member 1.
  • Suitable ba'le means may be provided for deecting streams of molten metal issuing through the -openings 13 to 18 so as to prevent such streams from impinging directly upon the mold members 1 and 2.
  • the architect means may take the form of an inner annular baflle member 19 which is mounted on or integral with the inner trough and extends downwardly into the annular space 3, as well as an outer annular baffle member 20 which may be mounted on or integral with the outer trough 6 and which also extends downwardly into the annular space 3. In this way, direct impingement of streams of molten metal onto the mold members 1 and 2 is prevented as may best be seen in Fig. l.
  • annular ABC members 19 and 20 may be replaced by downwardly extending ABC portions arranged opposite the opening means of the opposite trough, i. e., the annular baille member 19 may be replaced by three baille portions which are opposite the outer openings 16, 17 and 13, respectively, and the'annular baffle member 20 may be replaced by three baflle portions which are opposite the inner openings 13, 14 and 15, respectively.
  • bafe portions may be replaced by two baffle portions, one on the outer trough 6 and located opposite the inner opening 15 and the other on the inner trough 5 and located opposite the outer opening 18 inasmuch as the streams of molten liquid issuing through these two openings and 18 are particularly likely to impinge directly upon the mold members 1 and 2, respectively, as may readily be seen in Fig. l.
  • awless and uniformly cast thick-walled tube or pipe 1 may be obtained.
  • FIG. 3 and 4 The embodiment illustrated in Figs. 3 and 4 is similar to that illustrated in Figs. 1 and 2 except that the innerA and outer troughs 21 and 22 may be rotated independently of each other about the central axis of the an* nular space 3. Accordingly, separate drive means 23 and 24 kare provided, which drive means are adapted to rotate the troughs 21 and 22 in opposite directions, as indicated by the arrows in Fig. 4.
  • the outer peripheral side wall portion of the inner trough 21 is provided with similar openings 25 and inner peripheral wall portion of the outer trough Z2 is provided with similar openings 26.
  • the openings 25 and 26 are fashioned so that the streams of molten metal issuing therethrough will impinge upon the liquid level 4 approximately midway between the mold members 1 and '2, it being understood, however, that the opening means 25 and 26 may be fashioned Yso that the several streams of molten metal issuing therethroughV will impinge the annular liquid level While molten metal is supplied to the inner and outer supply means being rotatable about said 4 4 at dilerent places, i. e., near the inner or outer edges thereof.
  • the inner and outer baffle members associated with the embodiment shown in Figs. 3 and 4 are preferably annular ones so as to be adapted to prevent any streams of molten metal from impinging directly upon the mold members 1 and v2, irrespective of the relative position of .the troughs Z1 and 22.
