Definitions

  • the present invention relates to a rolling mill, in particular a cold rolling mill for cold rolling a metal strip, with at least one cold rolling mill, with the cold rolling stand upstream uncoiler, wherein between the uncoiler and the cold rolling stand, a unit is interposed.
  • the present invention also relates to a method of rolling.
  • the FR 7534844 shows a cold rolling plant wherein between the uncoiler and the cold rolling stand a unit is interposed, wherein the unit is formed from at least three rotationally driven about a rotation axis rollers, and wherein two of these roles individually or jointly in a direction transverse to the axis of rotation by means of a drive and adjusting device is adjustable.
  • a metal strip has to be split in the longitudinal direction in order to be able to process it on a rolling mill with a smaller rolling width.
  • the cross-section of such a longitudinally divided rolled strip is then often not symmetrical.
  • the band is thicker on one side than the other.
  • Such asymmetric rolling belts run out of the center of the rolling mill during operation.
  • a correction of the strip run is required. Only if an exact inlet position of the rolled strip can be maintained in the cold rolling stand, the specified in a cold rolling process tight tolerances can be met.
  • a unit is used between the uncoiler and the first rolling stand, which is formed from at least three driven rollers, wherein the spatial position of these rollers is variable by means of a drive and adjusting device.
  • each of these rollers of the 3-roller system is adjustable in the direction of its roller axis. This adjustment can be done individually or together.
  • the inlet of the rolled strip must be as symmetrical as possible. This is the only way to guarantee the accuracy of the strip thickness required for cold rolling.
  • a wedge-shaped band profile in particular tends to run out of the center of the rolling mill. A band deflection is advantageous here.
  • each of these rollers is adjustable in a direction transverse to the axis of rotation by means of the drive and adjusting device.
  • a substantial simplification in the threading of the metal strip is achieved:
  • the threading can also be supported by a transfer table.
  • a pinch roller, with which the tape head is pressed in the direction of the supporting two roles, can thereby provide further assistance in threading, especially for very stiff and thick tapes.
  • the threading process is then completed.
  • the work rolls create a strip tension on the metal strip.
  • the central roller of the 3-roll system By setting the central roller of the 3-roll system, the specification of a desired strip tension in the inlet to the first (cold) stand is very easy.
  • the middle role of the 3-roller system immersed in the located between the two supporting roles section of the metal strip.
  • the spatial position of the three roles specifies the wrap. The deeper the immersion, the larger the wrap.
  • a desired return tension can be set by appropriate control of the drives, without this strip tension acting on the upstream, between uncoiler and the 3-roller arrangement comparatively lesser Bandzug the metal strip during unwinding.
  • fluctuations in the strip tension during unwinding of a loosely wound coil on the inlet into the cold rolling mills do not propagate.
  • the 3-roller system acts as a tensile decoupling during the rolling process.
  • the axis of rotation of the reel lying to the reel and the axis of rotation of the roller lying to the cold rolling stand lie in a plane and that the roller between them is spatially adjustable with respect to this plane.
  • the advantageously high strip tension can be set in the inlet to the first cold rolling stand.
  • an embodiment may be advantageous in which the middle roller by means of a hydraulic actuator between the pivoted position in which this roller is separated from the rolled strip, and the pivoted position in which the peripheral surface this role is partially wrapped by the rolled strip, is adjustable.
  • the middle roller immersed sufficiently deep, that is, when the wrap of the middle roller is disposed below the plane spanned by the axis of rotation of the other two rollers plane, and if the wrap the two supporting roles is above this level.
  • a particularly high strip tension in the inlet region can then be adjusted if the adjustment of the middle roller takes place in such a way that the middle roller has a loop of greater than 180 °.
  • the distance of lying in the plane of two supporting roles by means of the drive and Adjustment can be changed continuously. This change can be brought about by moving both rollers toward or away from each other, whereby the looping and, as a result, the braking effect in the inlet can be given very differentiated.
  • the adjustment movement of the middle roller is a linear movement, which includes a predeterminable angle with respect to the plane.
  • the wrap of the three roles can be better adapted according to the desired influence on the tape.
  • the regulation of the drives of the rollers is technically easier.
  • the drive and adjustment determined from the measured signal of the tape layer, a control signal for adjusting the axial position of the 3-roller system, possibly also of the uncoiler.
  • FIG. 1 schematically shows a side view of the rolling mill according to the invention in a position in which the beginning of the tape is threaded into the rolling stand 1.
  • a rolled to a coil steel strip 2 is unwound from a reel 3 clockwise and passes from left to right in the direction of the unit 10.
  • This unit 10 is in Essentially of three rollers 6, 7, 8, of which the middle roller 7 is pivoted away in this operating position from the tape run and is not in engagement with the metal strip 2 (threading position).
  • the metal strip 2 is first transported on a part of a transfer table 13 and is subsequently supported by the roller 6, a second part of the transfer table 13 and the roller 8. In the case of very stiff metal strips, this threading operation can optionally be assisted by a pressure roller 19.
  • the transfer table 13 can be pivoted in and out by drawing drives, not shown in the tape.
  • each of the rollers 6, 7, 8 is rotationally driven by the driving and adjusting device 11 not only about the associated rotation axis 6A, 7A, 8A and (jointly or separately) in the axial direction adjustable, but also the local position of each roller 6, 7, 8 is adjustable in a direction transverse to its axis of rotation 6A, 7A, 8A by means of the drive and adjusting device 11.
  • the uncoiler 3 is adjusted in the direction of its axis of rotation 3A.
  • the metal strip 2 can be directed into the middle of the cold rolling stand 1.
  • drive and adjusting devices 11 with which a rotational movement and at the same time the spatial position of a roll (or possibly also a reel) can be set or adjusted in a rolling mill, can be actuated hydraulically or electromechanically. Such devices are assumed to be known in the following and therefore need not be explained in detail here.
  • FIG. 2 shows the condition during cold rolling. After the rolled strip 2 is threaded into the gap of the work rolls of the roll stand 1 and is detected by these, a strip tension is exerted on the metal strip 2. As already indicated, the strip tension and the strip run in the region of the inlet to the roll stand 1 should be able to be predetermined as independently of the strip tension in the area of the uncoiler 3. Variations in the tension during unwinding of the coil should preferably not reach the region of the inlet to the roll stand 1. As in FIG. 2 shown, the unit 10 is provided for this Buchentkopplung. The middle roller 7 of the unit 10 is pivoted in this illustration. The metal strip 2 wraps around a portion of the lateral surface of the three rollers 6, 7, 8.
  • Each roller 6, 7, 8 is, as I said, rotationally driven by a drive, not shown.
  • the drive torque of the rollers 6, 7, 8 is determined by the drive and adjusting device 11 so that on the one hand a braking effect is exerted on the metal strip 2.
  • This braking effect it is possible to maintain a desired minimum amount of tension in the inlet to the cold rolling mill 1.
  • This retraction tension is largely independent and unaffected by pull variations that can occur when unwinding a loosely wound coil.
  • the drive and adjusting device 11 also influences the spatial position of the axes of rotation of the rollers 6, 7, 8 (possibly also that of the uncoiler 3 in the direction of its axis of rotation 3 A).
  • a tape position detection 9 which is arranged between the unit 10 and the cold rolling stand 1.
  • the monitoring of the tape run for example, be done by the edge (s) of the metal strip is detected metrologically.
  • This band position detection 9 is signal-conducting connected to the drive and adjusting device 11. By the supplied measurement signal can be counteracted well with a conventional control a bleeding of the metal strip 2. This is advantageous in particular in the case of a cross-sectional profile of the metal strip which has the shape of a wedge.
  • FIG. 3 also shows the condition during the rolling process.
  • the middle roller 7 is deeply immersed below the two rollers 6, 8. This results in a large angle of the wrap of the roller 7, to which also a comparatively larger wrap angle of the rollers 6, 8.
  • This angle of wrap is adjustable by the position of the roller 6 and the position of the roller 8 respectively given in accordance with the arrow 14 becomes.
  • the axis of rotation of one of the rollers 6, 8 are displaced, or both. If the distance 18 between the axes of rotation 6A, 8A changes, the looping also changes.
  • the middle roller 7 for example, by a hydraulic actuator not shown between a pivoted position 16 and a pivoted position 17 adjustable.
  • This adjustment movement 21 can take place with respect to the plane 15 perpendicular or at an angle 20.
  • a change in the angle 20 of the adjusting movement 21 influences the wrapping of the rollers 6, 7, 8.
  • the axes of rotation 6A, 7A, 8A of the rollers 6, 7, 8 are parallel to each other and with respect to the plane 15.
  • 8A of the roller in Fig. 6, 8 spanned the plane 15.
  • the axis of rotation 6A and 8A of the outer rollers 6 and 8 is in the plane 15 (approximately in the strip running direction 5) in Direction of the double arrow 14 slidable.
  • the distance 18 of the two rollers 6, 8 are chosen to be very narrow, so that a high tensile structure can be realized by the 3-roller system. This is particularly advantageous when cold rolling thin and hard metal strips.
  • the angle 20 of the adjusting movement is predetermined with respect to the plane 15, the wrap of the rollers 6, 7, 8 can also be designed differently.
  • the above-described 3-roller system can be achieved in a simple manner at the same time a Glasentkopplung, a desired Switzerland initial in the inlet region and a good band deflection of metal bands.
  • a Buchentkopplung By the immersion depth of the middle roller 7 in conjunction with the horizontal adjustability of the two outer rollers 6, 8 of the 3-roll system can be set during cold rolling train construction in an advantageous manner and thus a high retraction tension in the following rolling stand 1 can be ensured.
  • the threading process is relatively simple even for rigid metal strips 2.
