Definitions

  • aspects of the present invention relate to high speed rod rolling mills, and more particularly to improvements to the laying heads employed in such mills to form the hot rolled product into a helical series of rings.
  • a conventional laying head 10 includes a housing containing a rotatably driven hollow quill 12.
  • the quill is subdivided into a tubular body 12a journalled for rotation between axially spaced bearings 14, 16, and a nose 18 detachably secured by means of a mounting flange 20 to the tubular body 12a.
  • the nose projects axially and forwardly in cantilever fashion from the tubular body.
  • the quill 12 carries a product guide, typically in the form of a three dimensionally curved laying pipe 22.
  • the laying pipe has an entry end 22a aligned with the rotational axis "X" of the quill 12, and a curved intermediate section 12b leading to a delivery end 12c spaced radially from axis X.
  • Hot rolled steel rod is directed into the entry end 22a of the laying pipe 22 along axis X, and exits from the delivery end 22c as a helical formation of rings (not shown).
  • the rings are additionally confined and moved forward by a helical guide trough 24 surrounded by a cylindrical shroud 26.
  • the guide trough 24 is configured and dimensioned to coact with the shroud 26 in providing an axially and radially confined helical extension of the guide path defined by the laying pipe 22.
  • the curved intermediate portion 22b of the laying pipe 22 is supported on the nose 18 by radially projecting struts 28, whereas the guide trough 24 is carried on a separate disc-shaped trough support 30 detachably mounted on the end of the cantilevered nose 18.
  • the disc-shaped trough support 30 may be seen as including a hub 32 at the center of a helical plate 34 on the outer rim of which are attached channel-shaped trough segments typically indicated at 24'.
  • the helical plate 34 is typically welded to the hub 32, with the resulting structure of the trough support 30 being robust and consequently heavy in order to withstand the stresses resulting from high speed operation of the laying head. Moreover, difficulties are encountered in accurately aligning the trough support 30 with the rotational axis X of the laying head, with even slight misalignments causing disruptive vibrations at high speeds.
  • WO 03/051553 A1 shows a laying head for forming an axially moving hot rolled product into a helical series of rings, said laying head comprising a quill rotatable about an axis, said quill having a tubular body journalled for rotation between axially spaced bearings, and having a nose projecting axially and forwardly from said body; a product guide carried by said quill, said product guide having an entry and aligned with said axis and arranged to receive said product; a guide trough providing a helical extension of said product guide.
  • aspects of the present invention include supporting both the product guide, which may comprise a laying pipe, and the guide trough, on a continuous helical support formed as an integral component of the nose projecting axially and forwardly from the tubular body of the quill.
  • the guide trough segments are subdivided into a continuous bottom comprising the outer rim of the helical support, with the side walls being segmented, detachably secured to the trough bottom, and readily replaceable when worn.
  • the conventional assembly of the nose 18 and separate disc-shaped trough support 30 depicted in Fig. 1 is replaced by a unitary nose 36, an exemplary embodiment of which is depicted in Fig. 4 .
  • the unitary nose 36 has a central tubular body 38 provided at one end with a mounting flange 40 adapted to be connected to the tubular body 12a of the conventional laying head quill 12 shown in Figs. 1-3 .
  • a helical support which may comprise a continuous auger plate 42 configured as an unwinding spiral scroll, is permanently joined to the central body 38.
  • the auger plate 42 extends continuously from the mounting flange 40 to the distal end of the central body 38.
  • a segment of the plate 42 carries brackets 44 on its rim.
  • the brackets 44 coact with clamps 46 to secure the laying pipe 22 in its operative position.
  • the remaining rim of the auger plate 42 is defined by a continuous collar serving as the bottom 48 of a channel-shaped guide trough 50.
  • the sides 52 of the guide trough 50 are segmented and detachable secured to the bottom 48 by conventional fasteners which may comprise bolts 54 and nuts 56.
  • An exemplary embodiment of a trough side wall segment 52 is depicted in Figs. 9A and 9B .
  • the side wall segments 52 are identical.
  • the side wall segments may be cast or fabricated from light weight wear resistant materials, illustrative examples including aluminum, aluminum alloys, carbon fibers, thermoplastics, etc.
  • the interior surfaces 52' of the side wall segments 52 may comprise or be coated with a wear resistant material, for example, a nano metal.
