Definitions

  • This invention relates to a continuous rolling mill and more particularly to apparatus arranged to produce elongated metal strip or sections by the rolling method.
  • Another object of this invention is the provision of a continuous rolling mill having two different sets of finishing trains, one for flat strip and the other for sections, in which the mill including one finishing train may be operated, while the rolls and guides in the other finishing train are being changed or adjusted.
  • a further object of the present invention is the provision of a continuous rolling mill in which the finishing stands of one type of product may be changed while prodnot from another set of finishing stands continues to be produced.
  • a still further object of this invention is the provision of a continuous rolling mill having two parallel finishing passes which are relatively close together, so that the angle of deflection from the roughing and intermediate pass is very small.
  • FIG. 1 is a side elevational view of the continuous rolling mill embodying the principles of the present invention
  • FIG. 2 is a plan view of the rolling mill
  • FIG. 3 is a sectional view of the mill taken on the line lllIll of FIG. 2.
  • the rolling mill is mounted on a floor 11 of a steel mill.
  • the rolling mill consists of a roughing train 12, an intermediate train 13, a first finishing train 14, and a secondary finishing train 15. All of the roll stands, particularly those in the roughing train and the intermediate train, are shown very schematically and in improper spacing for the sake of simplicity.
  • the first finishing train 14- consists of a vertical stand 16 driven by a motor 17 followed by a horizontal stand 18 driven by a motor 19 operating through a gear box 21. Following the stand 18 is another horizontal stand 22 driven through a gear box 23 by an electric motor 24. Next is mounted a vertical stand 25 driven by a motor 26.
  • a horizontal loop repeater 27 is interposed between the stands 22 and 25 and a forward uphill repeater 28 is also so interposed and extends toward the drive side.
  • a horizontal stand 29 driven through a gear box 31 by an electric motor 32.
  • a horizontal repeater 33 is mounted between the stands 25 and 29.
  • the horizontal stand 34 driven through a gear box 35 by a motor 35, there being a horizontal repeater'37 interposed between the stands 29 and 34.
  • a vertical stwd 38 driven by a motor 39, there being a horizontal repeater 41 interposed between the stands 34 and 33.
  • the last stand in the finishing train 14 is a horizontal stand 42 driven by a motor 43 and preceded by a horizontal repeater 44. Suitable guides are interposed between the stands and at the entrance and exit of each stand in the usual manner.
  • an upward forward repeater 46 similar in nature to the repeater 28. Both the repeater 28- and the repeater 46 terminate in a passline of the secondary finishing train 15 which begins with a horizontal repeater 4'7 which delivers stock into a vertical stand 43 driven by a motor 49.
  • a horizontal stand 51 driven through a gear box 52 by a motor 53.
  • a horizontal repeater 54 is interposed between the stands 48 and 51.
  • a vertical stand 55 which is driven by a motor 56 and is preceded by a horizontal repeater 57.
  • a horizontal final stand 58 driven by a motor 59.
  • the stands, motors, gear boxes, and repeaters of the secondary finishing train 15 are all mounted on the upper surface 61 of a monolithic reinforced concrete platform 62, the said upper surface being a substmtid distance above the surface of the floor l1.
  • the platform is generally rectangular and extends laterally across both of the roll passes including the main roll pass and'the secondary roll pass and is provided with suitable Stairways 63 for gaining access to the upper surface from the floor 1i.
  • Extending from the platform in line with the finishing train 15 is an inclined runout table 63 which inclines from a high end adjacent the platform to a low end on a level with the runout table 45 leading to the cooling bed.
  • a passage 64 Extending through the platform 62 in line wtih the main roll pass is a passage 64 having a bottom on a general level with the main pass line and carrying the runout table 45 Over'lying the passage 64 and forming its roof is a slab 65 of insulating material and overlying this is a metal cover plate 65.
  • a pipe s7 Embedded in the material of the platform in the area close to the surface 61 and on either side of the passage 64 are pipes s7 carrying a cooling fiuid, such as water.
  • a fan 63 Also introduced into the center or" the passage 64 is a fan 63 which introduces cooling air into the passage so that it fio-ws in both directions to cool the platform and the surfaces of the passage. This protects the operators from the heat radiating from the roll stock passing over the runout table 45.
  • the material to be rolled passes, first, through the roughing stands 12 where it receives its initial deformation and elongation, and then through the intermediate train 13 where its form is further changed.
  • the final (formation of the material takes place either in the finishing train '14 or the finishing train 15, depending upon the product which is desired.
  • the finishing train 14 is intended to form flat strip material, while the finishing train 15 is intended to form angles and other material of irregular cross section known as sections, including channels, I-beams, and the like.
  • the mill may be operated in any one of several ways. First of all, a strip may be finished in the finishing train 14 and passed over the runout table to the cooling beds, while no material goes through the finishing train 15.
  • the repeaters 46 and 28 are each provided in the usual manner with a switching means to cause the material being rolled to pass over into the finishing train 15 or to go straight ahead into the finishing train 14, depending upon the desired roll product. In some cases, before material is finished in the finishing train 15, it is desired to give it several more deformations and, for this purpose, the material would pass through the stands 16, 18, and 22 before being shunted laterally by the repeater 28 to pass it to the finishing train 15.
  • the surface 61 of the platform is maintained at a comfortable temperature, first of all, because of the provision of the insulating slab 65 overlying the passage 64, and secondly, by the provision of cooling through the pipes 67 and the fan 68;
  • the coolant in the pipes would be 4 Water from the regular water supply system and would be at ambient temperature which would be sufficiently cold to maintain the material of the platform at a comfortable temperature. In this way, it is possible for the operators to work on the finishing train 15 in comfort.
  • the material is thus allowed to pass in a high position because of the high position of the finishing train 15 on the upper surface of the platform 62. Causing the material to pass a considerable distance over the tops of the spindles of the finishing train 114 permits these spindles and drives to be readily accessible, even while material is being passed to the finishing train 15. This is necessary since, while the finishing train 15 is being used, the finishing train 14 may not be in operation and, on the contrary, may be subject to repair and maintenance as well as to roll changes. In any case, it is quite necesasry to be able to have access to the spindles and particularly the point where the s indles are attached by couplings to the roll necks.
  • Another method of operating the apparatus which is beneficial is that of finishing angles in the finish train 14 and finishing strip in the finish train 15; this has the advantage that the fiat strip is relatively easy to bend about its long dimension and can be deflected fairly easily into the secondary pass, while the sections (which presumably have a stifier cross section) can continue in a straight line through the finishing train 14 over the runout table 45 to the cooling bed.
  • finishing stand 15 there are a number of other advantages obtained by mounting the finishing stand 15 at a high position. For instance, since it is thereby possible to arrange all the drives at one side, shorter electrical power leads and shortor control lines for the drives may be used. Furthermore, as has been stated above, the deflection angle for the secondary roll pass is maintained very small, so that, in the finish trains, sections and fiat strip material can be rolled at the same time. By arranging the secondary roll train 15 closer to the cooling bed than the finish train 14, it is possible to have all the drives at one side so that it is not necessary for the roll stock of one finishing train to pass under the drives of the other finishing stand.
