Definitions

  • the preliminary reduction of the stock, as received from a heating furnace, not shown, is preferably eifectedin a roughing mill consisting asihere shown of fourstands of reducing rolls 1, 2,
  • the broadside transfer mechanism 17 may be rendered inoperative, and in this case the said stock, asrun out on conveyor rollers 18, is presented longitudinally .to a single stand of rolls 19, which constitutes part of another finishing mill, here shown as a staggered duo mill consisting of four stands of separated rolls- 19, 20, 21'and- 22, of which the rolls 19 and 21 are operated in the same direction as the rolls 15, while the rolls 2O thisstaggered duo finishing train, the stockand 22 are operated in the same direction as the alined stands of rolls 1 to 7 inclusive.
  • a staggered duo mill consisting of four stands of separated rolls- 19, 20, 21'and- 22, of which the rolls 19 and 21 are operated in the same direction as the rolls 15, while the rolls 2O thisstaggered duo finishing train, the stockand 22 are operated in the same direction as the alined stands of rolls 1 to 7 inclusive.
  • the stands of rolls 19 and 20 are. driven by suitable gearing 23 and 24 respec tively from the same motor 12 which operates the previously described roll stands, while the stands of rolls 21 and 22 are preferably driven from the independent motors 25 and 26 respectively.
  • a Y-transfer conveying mechanism 27 of well known construction which of reversible skewed conveyor rollers 28, 28 for alining the stock with the next roll stand 20 of said finishing train, and for presenting thereto that end of the stock which lastfemerged from the rolls 19; a similar Y- t'ransfer conveying mechanism29 is interposed between the stands of rolls 20 and 21 of the finishing mill and a third Y-transfer conveying mechanism 39 islikewise interposed between the stands of rolls 21 and.
  • a suitable runout 31' is adapted to deliver the stock to a cooling bed 32 of any desired construction.
  • the rolling is accomplished by four stand roughing mill, a two-stand infat rolls '5 and 15 and thereby constitutes an termediate mill, and a four stand finishing mill making in all, a ten-stand combination- Furthermore, according to the invention,
  • thebroadside transfer mechanism 17 may, if desired, be operated in a direction opposite to that previously described, whereby it will intercept the stock as delivered by the rough- ⁇ ing train 1, 2, 3, 4, and-transfer it broadside to the conveyor rollers 18, the latter, as befbre, serving for delivery of said stockto the staggered duo finishing mill 19, 20, 21 and 22.
  • This mode of operation cuts out from the passage of the stock, the'two stands of eight-stand arrangement, as distinguished from the ten-stand arrangement described immediately above. N
  • alined stand mill arrangement for example, is well suited for large angle, fiat and round sections, while the other mill arrangements are well adapted for agreat variety of smaller sections of angles, flats androunds.
  • the stock, .upon emergence fromvstand 15 may if deanother finishing train comprising roll stands in tandem arrangement, disposed insubstantial alinement with said roughing train and spaced apart therefrom, a series of intermediate. roll stands common to both of said 'finishing trains, one of said intermediate stands being. substantially alined with and interposed between said roughing train and said 9- second-mentioned finishing train and means selectivelyoperable in the passage of the stock from said roughing train to either of said finishing trains for making as many passes through said intermediate stands as ⁇ 1 may be required.
  • a series of stands of I rolls in substantial alinement comprising a plurality of stands of roughing rolls, a stand of finishing rolls, with provisiomfor open rolling between the roughing and the intermediate stands, iifcombmation with a group of additional finishing stands at one side of said substantially alined stands, means for broadsiding the stock as delivered by said intermediate roll stand, to aline it with the first stand. of said additional finishing rolls, a second stand of intermediate rolls preceding said first stand of additional finishing rolls,'means for passing the stock so broad sided repeatedly through the first and second stands of intermediate rolls, and means selectively op-- erable to finish the stock so broadsided in said additional finishing rolls, or in the firsti mentioned finishing rolls of said mill.
  • an offset finishing roll train comprising a. plurality of pairs of staggered roll ately adjacentto said roughing train, two
