Definitions

  • the invention relates to a method for rolling out metallic materials, in particular strip material, by means of at least one upper and one lower work roll and also relates to a rolling mill for performing the method.
  • the two work rolls acting on the rolling stock are driven in such a way that they have corresponding circumferential roll speeds, that is to say they have a speed ratio of 1: 1 to one another.
  • This known rolling process is carried out in such a way that the so-called flow sheaths lie within the roll gap, which is delimited on the inlet side by a normal plane to the rolling stock passage determined by the rolling stock inlet and on the outlet side by a normal plane determined by the rolling stock outlet.
  • the so-called flow sheath determines a synchronization point in the roll gap at which no relative speed occurs between the rolling stock and the circumference of the work roll.
  • the position of the flow sheath in the roll gap is adjusted in accordance with the forces acting on the rolling stock, for example the forward and backward pull, the horizontal component of the rolling forces and the frictional forces between the rolling stock and the work roll.
  • the stand is able to guide the rolling stock with the help of the work rolls.
  • the rolling stock speed is no longer determined by the work rolls, because the roller circumferential speed and the rolling stock speed do not coincide at any point in the roll gap.
  • Rolling with a position of the flow sheath in the vicinity of the rolling stock entry or exit is also problematic because, even with minor changes in the rolling conditions, for example the strip tension, an unstable condition can easily arise, which causes vibration phenomena, in particular rotational shrinkage of the work rolls, and the resulting slides on the rolling stock.
  • the object of the invention is to find a method for rolling out metallic materials, in particular strip material, of the generic type, and a rolling mill for exercising the same, which, using the advantages resulting from better lubrication of the higher stitch reduction during cold rolling, ensures adequate stability of the rolling process at all times guaranteed.
  • the so-called push-rolling method which is characterized in that the work rolls, which interact in pairs, are at a circumferential speed ratio which deviates from 1.
  • the peripheral speed ratio between the work rolls interacting in pairs is set such that there are always two different positions of the flowing edges for the faster and the slower working roll within the roll gap, according to the push-rolling method according to the invention there can be no or one flow sheath within the roll gap form.
  • a rolling mill for practicing the method is mainly characterized by the characterizing features of claim 10 and can be developed according to the features of claims 11 to 13.
  • the upper work roll 1 and the lower work roll 2 of a rolling mill are shown, between which, for example, metallic strip material is passed as rolling stock 3.
  • the length of the roll gap 4 between the two work rolls 1 and 2 is determined, on the one hand from the entry plane 5 which is normal to the direction of passage of the rolling stock 3, and on the other hand from the exit plane 6 of the same which is also normal to the direction of passage of the rolling stock 3, as is the case in FIG. 1 to 5 is clear.
  • the centering angles ⁇ 1 and ⁇ 2 are indicated, which are determined by the entry plane 5 and the exit plane 6 of the rolling stock 3 to the axes of rotation of the work rolls 1 and 2, which in each case the contact surfaces of the work rolls 1 and 2 determine with the rolling stock 3 over the length of the roll gap 4.
  • the centering angles ⁇ 1 and ⁇ 2 are each shown in the same size in FIGS. 1 to 5.
  • FIGS. 1a and 1b illustrate the speed ratios which result from the rolling process according to FIG. 1.
  • the roll peripheral speed V 0 or V u and, on the other hand, the rolling stock speed V w - at the entry 5 of the rolling stock 3 into the roll gap 4 with V E and at the outlet 6 of the rolling stock 3 from the roll gap 4 V A designated - plotted.
  • the respective vertical distance between V O and V W represents the relative speed between work roll 1 or 2 and rolling stock 3.
  • 1a and 1b illustrate that the circumferential speeds V and V u of both Ar seen over the entire roll gap 4 beitswalzen 1 and 2 are greater than the rolling stock speed V w and thus there is no flow sheath within the roll gap.
  • the work rolls 1 and 2 are operated at peripheral speeds V and V u which are lower than the rolling stock speed V.
  • the curves V and V 0 and V u do not intersect (see FIGS. 2a and 2b), so that there is no flow divide here either.
  • the speed ratios for the upper work roll 1 are as explained in connection with FIG. 1, ie the peripheral speed V of the work roll 1 is greater than the rolling stock speed V w (cf. FIG. 3a).
  • the lower work roll 2 is operated according to FIG. 2 with a circumferential speed V u below the rolling stock speed V w (cf. FIG. 3b).
  • the rolling process according to FIG. 4 corresponds to the rolling process according to FIG. 1 with regard to the speed relationships between the upper work roll 1 and the rolling stock 3 (cf. FIG. 4a).
  • the lower work roll 2 and the rolling stock 3 have identical speeds in the floating separation point F, that is to say the relative speed is 0 in the floating separation point F, and the rolling stock speed V w is lower before the point F in the direction of the entry plane 5 the point F in the direction of the exit plane 6, it is greater than the circumferential roller speed V u of the lower work roll 2.
  • the speed ratios in the area of the lower work roll 2 correspond to those according to FIG. 2, ie the rolling stock speed V w is always higher than the peripheral speed V u of the work roll 2.
  • the speed ratios in the area of the upper work roll 1 are such that here, as in FIG. 4b, a floating point F is formed.
  • the outlet speed V A of the rolling stock 3 in the exit plane 6 of the roll gap is to be lower than the peripheral speed V, V of the two work rolls 1 and 2, as indicated in FIG. 1, then it proves to be expedient to have the running speed of the rolling stock 6 from the inlet side of the roll stand by determining the entry speed V E of the rolling stock 3 either through a decoiler 7 or through a driver 8 arranged between it and the roll stand in the form of a pair of S-rolls.
  • the take-up reel 9 arranged downstream of the roll stand runs at a speed adapted to the outlet speed V A of the rolling stock 3.
  • FIG. 7 An arrangement according to FIG. 7 is expediently also used to operate the method according to FIG. 5, where a flow sheath F (on the upper work roll 1) is formed.
  • the work roll pair 1, 2 upstream and / or downstream rolling stock drivers 8; 12; 14, 16 or the rolled goods reel 7, 9; 10, 11; 13, 15 are set or have to be adjustable to a drive speed that differs from the roller circumferential speed;
  • the speed ratio required for the respective rolling process between the circumferential roll speed and the drive speed for the drivers or reel can be determined on the basis of a fixed speed for the work rolls 1 and 2.
  • the rolling stock inlet and the rolling stock outlet speeds can then be preset in a ratio corresponding to the respective pass reduction.
