  • the arrangement for delivering the'ingot from the plant comprises a curvilinear guide 8. Mountedfon said guide in its upper portion are rests 9 and 10 intended for bending the ingot fore-end and for separating the dummy bar respectively.
  • a pressure roller 12 Provided in the lower portion of the curvilinear guide 8 from the side of fibers tensioned in the process of bending is a pressure roller 12 imparting an active force for straightening the ingot.
  • the curvilinear guide 8 is suspended and secured on an articulated support 13 arranged between the rests 9 and 10 of the curvilinear guide, which support is rotated in the vertical plane by means of a hydraulic cylinder 14mounted on journals 15.
  • the rotation of the curvilinear guide 8 is required for displacing the pressure roller 12 when straightening the ingot and for moving the rests 9 and I0 effecting at the moment of rotating the curvilinear guide 8 the bending of the ingot foreend and separating the dummy bar respectively.
  • a stationary frame 16 Disposed above the pressure roller 12 of the curvilinear guide 8 is a stationary frame 16 provided with supporting rollers 17, 18, arranged at both sides of the pressure roller 12.

  • withdrawal roll table 20 (FIG. 2) is mounted on journals 25,
  • a roll table 28. (FIG. 5) is intended for maintaining the dummy bar in the horizontal position.
  • a roll table 29 (FIG. 4) is provided for withdrawing the straightened ingot.
  • the plant operates as follows:
  • molten metal is supplied to the plant in the main pouring ladle 1 (FIG. 1) and through the tundish 2 is brought to the mold 3'.
