Definitions

  • the presentinvention relates generally to rolling mills.
  • the invention resides in a novel disposition and arrangement of rolling mill apparatus, especially applicableto a general-purpose or jobbing mill, which is adapted to the rolling of a large variety of different sizes and sections.
  • the preliminary reduction of the stock as received from a heating furnace is preferably effected in a continuous roughing mill, here shownas constituted by two groups or trains of rolls, the first group, for example, comprising't'our stands of rolls 1, 2, 3 and 4, and thesecond group, for example,-comprising the stands of rolls 5, 6, 7 and 8.
  • the number of stands of 'rolls in these roughing trains may be varied at will without dcparting frpm the spirit and scope.
  • the continuously arranged roughing stands 1, 2, 3 and 4 are preferably driven each from an independent'source of power, as for instance, an adjustable speed electric motor 20, having interposed reduction earing 21 to obtain the low speeds require for said rolls.
  • the second train of roughing rolls constituted by the continuously arranged stands 5, 6, 7 and 8, are driven from another independent'source of power, name- 1y, as here shown, a separate and. distinct adjustable speed electric motor 22.
  • the several stan s ofsroughing rolls 1 to 8 inclusive, arranged for continuous operation, are each preferably provided with a plurality of independent rows of differently shaped passes, to give such variety as may be desired inthe cross section of the, reduced material emerging from the roughing mill. Said material as thus brought into condition for further f'ai'n-ication by rolling may be handled. in intermediate and finishing roll trains, in a variety of ways, as will now be described in detail.
  • the gearing for the rolls 9, 10 and 11 is arranged, as shown, to rotate them at progressively increasing speeds, thus to compensate for the elongation of the stock, due to its passage through said rolls.
  • a Y-transfer conveying mechanism 23 of well known construction is disposed in position to receive the stock from the roughing mill, and this mechanism provides the usual means, in the form of skewed conveyor rolls 24, 24:, for effecting the travel of each piece as received thereon in. the opposite direction, so as to present the rear end of said piece to the pass of the rolls 9.
  • a mill operator may seize the front end of each piece emerging from the rolling mill and enter it between the rolls 9, the stock in this instance forming a loop, as shown at 2'5.
  • the stock as it leaves the rolls 9 of the intermediate mill is susceptible of a variety of selective different dispositions, to meet the varying requirements that arise in a general-purpose or jobbing mill.
  • an operator may seize the first end of the stock emerging from the rolls 9 and enter itbetween the rolls 10, the stock, under these conditions, forming a loop, as shown at 26; then, after passage of the stock through the rolls 10, its'first end may be seized and entered stance forming a loop, as shown at 27.
  • the stock in this i61- r if desired, the stock as it leaves therolls 9 may be diverted from any further interme diate reduction, by being entered by an. operator between a pair of rolls 12, the stock in this instance forming a loop, as shown at 28.
  • said rolls l2 in addition to receiving the stock direct from the rolls 9 of the intermediate train may likewise receive the stock from the rolls ll of said intermediate train, the stock in this lastnamed instance forming a loop, as shown at 29.
  • the rolls 12 constitute, in the present arrangement, a part of the finishing mill which is made up additionally of the alined stands of rolls 13, 14 and 15, all of said finishing stands of rolls being here shown as driven from a third independent source of power, for example, a variable speed electric motor 30, from which a belt drive asindicated at 31, is taken to each of said finishing stands.
  • a third independent source of power for example, a variable speed electric motor 30, from which a belt drive asindicated at 31, is taken to each of said finishing stands.
  • Any one of the stands of rolls 1'2, 13, 14 or 15 is selectively available for finishing the stock, in advance of its projection onto a suitable runout, not shown, for delivery to a cooling bed or other receiving device, not shown.
  • stand 15 alone being the only one removed or rendered inoperative. Again, if the mill is operating for the production of strip material, such material may be finished either in the stand 12, or the stand 13,01 the stand 15; if finished in stand. 13, the space between,
  • stands 12 and 13 is sufiicient for the formation of a loop,'as shown at 32, and if finished in stand 15, the removal of stand 14 gives suflicient space between stands 13 and 15 for the formation of a loop, as shown at 33.
  • stand 14 gives suflicient space between stands 13 and 15 for the formation of a loop, as shown at 33.
  • the apparatus as above described possesses many of the advantages of a specialty mill, for the rolling of a relatively limited number of different sections, while at the same time eliminating the limitations on flexibility and other disadvantages that such a mill must usually work under.
  • the invention makes possible the selective rolling of a large variety of different sizes and sections with a minimum number of changes required in the apparatus to adapt it to the rolling of the various products required.
  • said stands of finishing rolls being spaced apart for the formation of free loops in said material between'said stands, when desired.
