Definitions

  • the invention relates to a method and a device for rolling a rolled strip in at least two roll stands, each with horizontally adjustable upper and lower work rolls, each of which is supported directly or via an intermediate roll on a backup roll, hot strip mill, or a reversing stand, on the at least two passes are rolled, in which the rolling strip is subjected to a state control, for which purpose actuators which provide profile and flatness act on the rolling strip.
  • the thermal crowning and wear of the work rolls as well as the elastic deformations are subject to relatively large changes within a rolling program. Without the correction by actuators, the crown of the work rolls increases continuously with increasing throughput of the rolling material, and due to the changing thermal crowning, the roll contour deviates increasingly from the target contour, e.g. a parabola.
  • CVC Continuous Variable Crown
  • suitable actuators such as sliding and / or bending members, e.g. "CVC” (Continuously Variable Crown) shift (see. DE 30 38 865 C1) or a suitable cooling, in order to compensate for the adjustment of the actual contour.
  • CVC Continuous Variable Crown
  • the invention has for its object to provide a method and an apparatus with which the requirements for profile accuracy and flatness of the rolled strip can be met despite flexible rolling programs.
  • the invention is based on the knowledge found and exploited by extensive investigations that cross-material flow also takes place in the middle rolled strip area in the case of thick strip, whereas cross-material flow is only possible in the edge region in the case of thin strip. So if the strip profile shape is to be changed in the middle rolled strip area, this can only be achieved with thick strip. On the other hand, a change in the shape of the strip can also be achieved in the case of thinner strip, without impermissibly high unevenness, but this can only be carried out in the closer strip edge area. With decreasing strip thickness, the relevant strip profile influenceability gradually moves outwards, ie towards the strip edge.
  • the actuators can be used in such a way that, taking into account the technological limits (e.g. rolling force, temperature, etc.), the flatness limits (these result from the respective material cross flow of the strip and thus represent physical limits), If necessary, also higher order, actuator limits and, in particular, taking into account the material cross-flow behavior, an optimal belt shape is created that comes as close as possible to the specified target contour.
  • technological limits e.g. rolling force, temperature, etc.
  • the flatness limits (these result from the respective material cross flow of the strip and thus represent physical limits)
  • actuator limits and, in particular, taking into account the material cross-flow behavior an optimal belt shape is created that comes as close as possible to the specified target contour.
  • Y the strip thickness coordinate
  • X the Represents bandwidth coordinate.
  • the mechanical actuators are used in such a way that there is a minimal deviation between the calculated strip shape and the target strip shape or target contour. If the strip profile shape cannot be produced in the stand i, the mechanical actuators must be adjusted in order to minimize the deviation. Deviations of the calculated strip shape from the target strip shape can be weighted differently over the bandwidth.
  • An embodiment of the invention provides that the mechanical actuators are supported by non-mechanical actuators, for which purpose - depending on the contour of the belt, in particular in the edge area - advantageously used work rolls as mechanical actuators can be locally heated or cooled.
  • work rolls used as mechanical actuators can be ground during the rolling operation. This can be achieved, for example, with oscillating grinding plates and allows the rolls to be smoothed or polished or their contours changed for the purpose of specifically influencing the strip contours.
  • Such an "on-line” grinding is recommended, in particular when changing the program to wider rolled strips, because grinding the work roll ends while the narrow roll strips are still rolling has no influence on the quality of these narrow strips, since the preparatively ground work roll ends are outside the roll width lie.
  • the mechanical actuators be used as early as possible. Under Taking into account the limits to be complied with, for example the flatness and the setting range, the aim is to achieve the target contour of the profile of the rolled strip as early as possible. If this is not yet possible in the first scaffolding, the task is automatically passed on to the subsequent scaffolding. Should the strip shape change from roll stand to roll stand or from constant to constant from stitch to stitch, a deviation can be tolerated in accordance with the law of material cross-flow with thicker strip in the edge area, ie the achievement of the strip shape or target contour in the middle rolled strip area has priority. If it is possible to create the strip profile shape on a roll stand, eg stand k, the ultimate goal is to keep this strip shape constant in the subsequent stands.
  • the actuators comprise axially displaceable work rolls and / or work roll bending devices.
  • CVC, work roll bending, roll interlocking, etc. can preferably be carried out or used. If, for example, wide strips are rolled, the non-parabolic effect of the work roll bending, i.e. the larger effect in the band edge area (200mm) has to be taken into account and a combination of e.g. To implement CVC and work roll bending that comes closest to the target or target belt contour.
  • the mechanical actuators can be supported by other actuators. It is therefore proposed that the work rolls be provided with zone cooling and / or a thermal cover in order to support the mechanical actuators in this way.
  • work roll cover shells for example, can be positioned at a suitable point on the ends of the work rolls.
  • a supporting influence on the rolled strip shape can also be achieved by changing the strip edge temperature within the technological limits.
  • induction heating can be used to change the edge heating in front of and / or behind the first scaffolding of the finishing train, or by e.g. Spray nozzles in the side guides cool the strip edges, which can be an advantage for austenitic stainless steels to be rolled.
  • the belt contour can be influenced by lubricating the work rolls in the area of the strip edges.
  • the work rolls can be provided with a special grinding. This can be provided, for example, in the form of a parabolic contour change or by a local conical course in order to bring about corresponding contour changes in the band edge area.
  • the rollable shape can be influenced by a change in the rolling force in the rear roll stands in the edge area, and a rolling force redistribution may be carried out within the permissible limits.
  • the accompanying changes in the body crowns on the corresponding and others Roll stands can be compensated for by actuators that do not act on the edge - eg with CVC - in order not to disturb the mass flow there and thus to avoid undulations of the rolled strip.
  • the algorithm is used in online operation. However, it can also be used in combination with an optimization algorithm for the optimal compilation of rolling programs and optimal use of actuators in advance. Not only one strip, but the entire rolling program is considered and optimized with regard to the strip contour.
  • target contours 1 and 2 of the profile of a rolled strip 3 and 4, not shown, are given in accordance with the intended use in FIGS. 1 and 2.
  • a target contour 1 according to FIG. 1 for example, and a target contour 2 according to FIG. 2, for example, are desired for a rolling strip 3 to be processed directly.
  • FIG. 1 is an almost parabolic target contour
  • target contour 2 according to FIG. 2 has a flat body crown and a somewhat greater drop on the band edges.
  • the C40 point entered for both target contours 1, 2 results from the difference between the thickness of the rolled strip 3 or 4 in the middle H M and the mean value of the thicknesses measured at a distance of 40 mm from the strip edge 5 on each side or strip edge 5 of the rolled strip 3 or 4.
  • the creation of the target contours 1 and 2 presupposes the knowledge resulting from FIGS. 3 to 5, namely that a strip contour influence can only be achieved where a material cross flow is possible.
  • a material cross-flow also takes place in the middle, ie the area adjacent to the middle of the strip (see FIG. 5), whereas in the case of rolled strips with a smaller thickness below H crit , a material cross flow only takes place in the strip edge area.
  • the limit value of the thickness, ie, the critical thickness H crit can be for any hot strip tandem mill as a function of roll material, experimentally determined temperature, roll diameter as well as decrease or stitch distribution, it is generally known that an effect on the profile of the rolled strip, with simultaneous avoidance of planar defects achieved only can be as long as the Flow resistance of the material transverse to the rolling direction is still so low that in addition to the strip elongation there is a minimum amount of strip spreading in the roll gap.
  • a material cross flow below the critical thickness (for example 10 or 12 mm) over the bandwidth is only possible to a very small extent. This relationship is also clear from FIG. 5, in which, in addition to the coordinates for the material cross flow and the bandwidth, the material thickness is also entered.
  • FIGS. 6 and 7 show the strip profiles to be achieved using the known rolling processes (see FIG. 6) and the profile and flatness control according to the invention (see FIG. 7) within a rolling program comprising fifty strips or coils; the numbers circled at the bottom left indicate the number of coils. While in both cases the shape of the profile is still almost unchanged for the first strip or coil to be rolled, the effect of the thermal crown on the work rolls with the disadvantageous anomalies for the profile increases with the number of strips in the known rolling methods. flat strip profiles and edge beads are produced (see FIG. 6 the strip profiles after the rolling of 10, 20 or 50 strips). In contrast, according to FIG. 7, the band profile can be kept largely constant, and edge beads are avoided. The target tape contour is also almost reached.
  • FIG. 8 A hot strip tandem mill 6 that enables the desired strip profiles (see FIG. 7) to be reached is shown in FIG. 8, in part very schematically and with only symbolic identifications for the mechanical actuators including the elements supporting them, and in the form of black boxes for computers and measuring devices .
  • It consists of several roll stands, of which the first and last roll stands 7 and 8 are shown. However, it can also be a rolling mill with a reversing stand on which several passes are rolled.
  • Each of the roll stands 7, 8 has horizontally adjustable upper and lower work rolls 10, 11 supported by support rolls 9.
  • the latter can be moved axially, preferably with a CVC shift 12, as well as with work roll bending devices 13; the work rolls to be axially displaced (provided with a ground, thermal and wear contour) or the CVC shift 12 and the work roll bend 13 are used as mechanical actuators which act either in the strip center region or in the strip edge region.
  • a strip edge heater 14 is arranged in front of and behind the first stands of the finishing train to change the edge heating of the rolled strip 3 or 4.
  • the hot strip tandem mill 6 has a work roll zone cooling 15 in the area of the front or rear roll stands, e.g. in the form of spray nozzles directed in the corresponding zones onto the work rolls 10, 11, as indicated behind the first roll stand 7.
  • a band edge cooling 16 with e.g. spray nozzles and work roll cover shells 18 arranged in the side guides, as shown for the last roll stand 8.
  • the lubrication of the work rolls 17 in the strip edge area influences the load distribution in the roll gap and thus the strip contour. Thickness, flatness and temperature measuring devices 19, 20, 21 are also arranged behind the last rolling stand 8.
  • the measuring devices 19 to 21 as well as the mechanical actuators 12, 13 and the thermal and other influencing elements 14 to 18 are connected to a strip contour and flatness computer 22.
  • the measured data determined, in particular for the profile and the flatness of the finished rolled strip 3, 4, can therefore be used directly to correct the upstream control systems or actuators, with the aim of achieving the predetermined target contour of the profile of the rolled strip for all strips.
  • a pass schedule calculator 23 supplies the strip contour and flatness calculator 22 with input data.
  • a data feedback 24 is intended for the purpose of redistributing the rolling force.
  • the procedure described for achieving a predetermined target contour of the profile of the rolled strip is used in online operation. Nevertheless, when creating the rolling program (planning the rolling programs), the processes can be simulated offline in advance and the strip shape in particular can be determined in this way. If it turns out that the optimization process carried out beforehand with regard to a strip shape for certain strips is not successful, the rolling programs can be changed over or the strips can be used in another rolling program. Also included can be a cyclical displacement of the rear work rolls or roll stands adapted to the rolling program and / or an optimized positioning, for example, of the cover shells 18 for the thermal crown influencing of the work rolls 10, 11. After the strip has been selected or the rolling program changed, the target contour begins optimizing process from scratch until offline, ie can achieve an acceptable band shape in advance.
