Definitions

  • a further aspect of the present invention is to provide rigid shims inserted between the supporting frame and carriage to vary the height of the supporting frame.
  • the shims are constructed and arranged to be inserted and removed when the carriage mounting the supporting frame is removed from the roll housings. This method of adju'sting the height of the supporting frame and, thus, of the vertical rolls affords an extremely simple means of setting the pass line elevation.
  • lifting or tilting tables I are usually employed to convey the stock traveling on the approach roller table into the rolling mill passesi'ljifting tables are essential because, on the one hand, the level of the transporting surface of the approach table is fixed and, on the otherhand, the height of the pass line will be determined and fixedjn relation to the surfaceofthe rollertablebythe largest structural shape to Abe rolled.
  • lifting or tilting tables I are usually employed to convey the stock traveling on the approach roller table into the rolling mill passesi'ljifting tables are essential because, on the one hand, the level of the transporting surface of the approach table is fixed and, on the otherhand, the height of the pass line will be determined and fixedjn relation to the surfaceofthe rollertablebythe largest structural shape to Abe rolled.
  • the present invention is particularly useful in a universal rolling mill having a supporting frame (cassette) carried and retained in the windows of the roll housings.
  • the frame receives betweenits vertical walls both the vertical rolls and, in the same plane, the horizontal rolls complete with chocks.
  • the solution taught by the invention is substantially to mount the supporting frame or cassette on a traversable carriage that is vertically adjustable in relation to the housing windows.
  • a universal mill embodying the features of this invention can be adjusted to height, by simple means, so that the beams or sections are transferred directly from the approach table at accurate right angles into the roll gap;
  • FIG. 2 illustrates the same universal mill shown in FIG. lvexcept arranged for rolling narrow beams
  • FIG. 3 is a detailed view of a universal mill, viewed in the direction of rolling, illustrating the supporting frame mounting the horizontal and vertical rolls removed from the mill housings;
  • FIG. 7 illustrates a fourth embodiment of means for adjusting the height of the supporting frame.
  • the height of the roll pass x-x of the universal mill 3 does not coincide with the height of the conveying surface y-y of the roller tables 4.
  • the supporting frame 8 is adjustably mounted on the carriage 9 to enable the pass line xx of the universal mill 3 to be brought into a proper relation with the level of the conveying surface yy of the approach table 4 so that the oncoming beam or section enters the universal mill 3 in a straight line.
  • this height adjustment is effected by the use of shims 10 inserted between the carriage 9 and supporting frame 8.
  • the number and thickness of the shims 10 inserted will depend on the width of section to be rolled by the set of rolls installed in the supporting frame 8.
  • the shims 10 are placed on the carriage 9 before the supporting frame 8 is lowered thereon. I
  • FIGURE illustrates a second embodiment of the present invention wherein in place of shims 10, threaded spindles 11 are arranged between the support frame 8 and carriage 9.
  • FIGURE 6 illustrates a further embodiment of the 1 assemblies 13 arranged between the support frame 8 and the carriage 9.
  • the above additional embodiments of adjusting means have the advantage of permitting the height of the supporting frame 8 to be practically infinitely varied in relation to the carriage 9.
  • a univarsal rolling mill according to claim 1 wherein said means for adjusting comprises:
  • a universal rolling mill according to claim 1 wherein said means for adjusting comprises:
  • a universal rolling mill according to claim 1 wherein said means for adjusting comprises:
  • a universal rolling mill according to claim 1 wherein said adjusting means comprises:
