Definitions

  • the invention relates to a method for producing rolled strip with high strip profile and strip flatness quality, in which the rolled strip is passed through a hot strip tandem mill and possibly through a cold strip tandem mill and is thereby subjected to a state control during the rolling process, which is at least in a roll stand a strip profile control and comprises a flatness control in at least one further roll stand.
  • condition control comprises various control processes such as, for example, the speed control, the thickness control, the strip tension control, the strip profile control and the strip flatness control, which can influence one another to a greater or lesser extent and thus also have corresponding repercussions on the condition of the rolled strip.
  • profile correction is based on a material flow along and across the rolling direction.
  • the ability of the material to flow transversely to the rolling direction depends on the geometric rolling conditions, such as thickness, decrease, width and roll diameter, as well as other parameters such as material strength, strip temperature, and coefficient of friction Roll and rolling stock and the strip tension dependent.
  • the invention is therefore based on the object of designing the generic method in such a way that the cold strip tandem mill from the hot strip tandem mill is already offered a rolled strip with high strip profile and strip flatness quality for further processing.
  • condition control takes place in the hot strip tandem mill and, up to a thickness of the rolled strip, below which the material control in the width direction can no longer be achieved, comprises a strip profile control and is then restricted to a strip flatness control.
  • strip profile control should be above and the flatness control should be below a critical thickness, which is, for example, about 12 mm.
  • This type of process is based on the knowledge that a profile influence on the rolled strip can be achieved while avoiding flatness errors, as long as the flow resistance of the material across the rolling direction is still so low that a minimum amount of strip width is set in the roll gap in addition to the strip elongation. It was found that today with regard to the work roll diameter l cozy interpretation of the hot strip tandem mills is the limit for a profile influence of the rolled strip, with simultaneous avoidance of flatness errors in said rolled strip thickness of about 12 mm. This limit value of the thickness, i.e. the critical thickness, can be determined experimentally for each hot strip mill depending on the rolling material, temperature, roll diameter and decrease or pass distribution.
  • the last strip profile control and the first strip flatness control in the hot strip tandem mill are shifted between two successive roll stands in accordance with a shift in the critical thickness occurring during the rolling out of different thicknesses of hot strips.
  • Another procedural measure is to shift the critical thickness between the second and third roll stands and at the same time to shift the influencing limit of strip profile control and strip flatness control from the area in front of the third roll stand to the area behind the third stand.
  • the critical thickness can be behind the second roll stand, for example, for thin hot strip behind the second roll stand and for thick hot strip behind the third roll stand .
  • these process features are paint especially important.
  • An advantageous device for practicing this method is that in the hot strip tandem mill a group of roll stands with a roll gap height equal to or greater than the critical thickness are assigned to profile measuring devices and profile controllers which are connected to strip profile actuators on the roll stands, while the last roll stand this group and all remaining roll stands of hot strip tandem mill Planheitsmeßello and flatness controller comprise, e are connected to the strip flatness control elements. It is essential that the last rolling stand of the group can be influenced either by a profile measuring device and a profile controller or by a flatness measuring device and a flatness controller. The profile measuring devices or the flatness measuring devices are arranged downstream of the roll gap to be controlled. In particularly stored cases, the strip flatness control can be continued in the cold strip tandem mill.
  • the invention therefore provides, alternatively, to solve the above-mentioned object in a modified second type of process with a considerably lower technical outlay, in that, based on a profile or flatness measurement of the rolled strip emerging from the last stand of the hot strip tandem mill, in addition to one known correction of the band flatness control and the band profile control in this stand, after a computer comparison of the measurement results with specified target values, corresponding corrections of the strip profile control only in the last, if necessary, the last and penultimate of the rolling stands influencing the strip profile above the critical thickness, and corrections of the strip flatness control, each delayed by the advance period of the profile-corrected strip section, in the roll stands following these roll stands.
  • the roll pressure increases caused by short changes in the strip length over the strip length can be measured and, after comparison with predetermined target values, introduced in the computer comparison of the measurement results of the profile and flatness measurement, can result in additional corrections of the strip profile control.
  • a flatness measuring device and behind this a profile measuring device can be arranged behind which the flatness measuring device with a flatness computer, the output signals of which influence devices for adjusting and bending the rolls of the nth, the profile measuring devices a profile computer, the output signals of which influence devices for adjusting and bending this roll stand and preceding roll stands, and flatness computers and profile computers are connected to a computing unit with comparison devices and setpoint memories.
  • the flatness control now acts in a form known per se only on the last rolling stand of the hot strip tandem mill.
  • the profile measuring device at the end of the street is used first the deviation of the band profile generated by this was determined.
  • the required adjustment of the roll gap of the last stand, that is to say of the nth stand is automatically determined with the aid of pre-calculated characteristic curves for the actuating behavior of the roll set. Subsequently, he un- t Assuming a constant elongation of the belt over the bandwidth step by step, the required adjustment of the roll gap shape in the foregoing frameworks determined.
  • the roll gap shape actuators of the first size or sizes are now automatically adjusted to the extent calculated. Delayed by the transport time of the material from the adjusted scaffold to the next, not yet adjusted, this next scaffold is then also adjusted. This procedure is continued until the last of the roll gaps has also been adjusted to the pre-calculated amount.
  • the control dynamics of the profile control is limited by the transport times of the rolled belt from the point of adjustment (first stands of the road) to the place of measurement (behind the last stand).
  • the control dynamics are sufficient to prevent slowly occurring profile changes (roll wear, thermal crowning) to compensate sufficiently quickly.
  • Relatively quick and short-term profile changes e.g. as a result of short-term changes in the rolling force, cannot be compensated for by the corresponding backward regulation as a result of the transport routes (up to 20% short-term increase in the rolling force when rolling over rail points (skidmarks) cause additional bending of the roller sets and thus distort the profile of the strip and its flatness.
  • the change in the shape of the roll gap as a result of a change in the rolling force is calculated for each roll stand, depending on the strip and roll dimensions.
  • the change in manipulated variable required to compensate for this change can be represented in equations or sets of curves and automatically taken into account.
  • the rolling force of each roll stand is thus recorded with the force measuring devices already present and changes in the force are compensated for directly in accordance with previously determined curves by interventions in the profile actuators (e.g. work roll bending force).
  • the profile actuators e.g. work roll bending force
  • nip shape setting values which are improved in the course of the rolling by the interventions of the closed flatness and profile control loops, are used step by step with the Improve the data of the pass schedule and the preset values saved in the material data.
  • the increase in the strip profile in the middle of the strip is in the range from 0.5% to approx. 1.5% of the final thickness.
  • the control objective is to minimize the elevation of the strip center or to a predetermined value of e.g. 1.0% of the nominal thickness can be set reproducibly.
  • the setting range for setting the roll gap shape should therefore ideally be 0.75% of the nominal thickness and should still have sufficient reserves to compensate for changes in rolling force and other disturbances.
  • the profile and flatness control can be limited to the last two to three passes.
  • the last two to five passes for profile and flatness control are required (the low number applies to large final thicknesses h> 5 mm and the higher number applies to small final thicknesses).
  • the strip profile actuators can be used to roll bend, roll adjustment, roll limitation, roll swiveling, zone cooling of the roll bales as well as axial work roll, intermediate roll (e.g. with six-high stands) and support roll displacement in the corresponding roll stands of the hot strip tandem mill can be influenced individually and / or simultaneously.
  • the hot strip tandem mill according to FIGS. 1 to 3 comprises, in addition to the five roll stands 1 to 5, a take-up reel 6 for the hot strip 7 provided on the outlet side.
  • a profile measuring device 8, 9 and 10 is provided behind each of the roll stands 1, 2 and 3, and that Roll stand 3 is designed so that the rolled strip running out of its roll gap can have a maximum thickness of approximately 12 mm.
  • Each of the profile measuring devices 8, 9 and 10 works together with a profile controller 13, 14 and 15, while the flatness measuring devices 10 ', 11 and 12 are each assigned a flatness controller 15', 16 and 17.
  • the strip profile can be scanned on each of the rolling strips 7 emerging from the roll stands 1, 2 and 3 via the profile measuring devices 8, 9 and 10, the resulting measurement values being supplied as actual values to the profile controllers 13, 14 and 15 and with the target values stored therein can be compared, which correspond to the optimal strip profile in the area of the respective roll stand 1, 2 and 3.
  • the difference values resulting from the respective comparison are given as manipulated values on belt profile actuators of stands 1, 2 and 3.
  • the belt profile actuators can act on the roll bending, the roll adjustment, the roll limitation, the roll swiveling, the zone cooling of the roll bales as well as the axial work roll, intermediate roll (for example in the case of six-high stands) and backup roll displacement, advantageously in this way, that the available control options for the belt profile can be used either individually or with several or all at the same time.
  • a so-called CVC roll stand (DE-PS 30 38 865) can also be used as a means of influencing the strip profile.
  • the belt profile actuators can also cause the CVC rollers to move axially. It is important that the rolled strip 7 emerging from the roll stand 3 has an optimal strip profile, even if it slightly exceeds the "critical thickness" of approximately 12 mm.
  • the rolling strip 7 emerging from the roll stand 3 must have a minimum of strip flatness, at least when it slightly exceeds the "critical thickness" of 12 mm when it emerges from the roll gap.
  • a strip flatness control 10 ', 15' to the last roll stand 3 which can still be operated with strip profiles 10, 15 and which corresponds to the strip flatness controls 11, 16, 12, 17 of the roll stands 4 and 5 corresponds.
  • the arrangement is such that the rolling stand 3 depending on the acceptance or pass provided in the hot strip tandem line according to the respective pass schedule Distribution can be operated either with strip profile control 10, 15 according to FIG. 2 or with flatness control 10 ', 15' according to FIG. 3.
  • the mill stands 4 and 5 of the hot strip tandem mill are operated exclusively with flatness control 11, 16 and 12, 17, respectively, so that the hot strip 7 that runs out of the hot strip tandem mill and is taken up by the take-up reel 6 has a finished thickness that is both over 3 mm (FIG. 2) and can also be less than 3 mm (Fig. 3), in addition to an optimal strip profile, it also has a considerable flatness quality.
  • the rolling stand 3 can thus be driven either with profile control 10, 15 or with flatness control 10 ', 15'.
  • FIGS. 2 and 3 A comparison of FIGS. 2 and 3 makes it clear that the limit from influencing the profile to influencing the flatness of the hot strip either between the third roll stand 3 and the fourth roll stand 4 (FIG. 2) or between the second roll stand 2 and the third roll stand FIG. 3) can lie.
  • the profile controller 15 responding to the profile measuring device 10 and the flatness controller 15' to the flatness measuring device 10 'between the third roll stand 3 and the fourth roll stand 4 can.
  • the profile control 10, 15 for the roll stand 3 can optionally work by reaching through to the roll stands 1 and 2, whereby with such a reach-through control the own profile control 8, 13 or 9, 14 of the roll stands 1 and 2 could be omitted.
  • the profile measuring device 10 for the roll stand 3 can also be arranged behind the stand 4 or 5, for example. This also applies if a flatness correction is made in stands 4 and 5.
  • a thinner hot strip 7 with an initial thickness of 30 mm is to be rolled down to an even thinner final thickness of 2.5 mm.
  • the hot strip behind the first roll stand 1 has a thickness of 15.3 mm, while behind the second roll stand 2 it already falls below the —critical thickness “of approximately 12 mm, namely 8.3 mm thick.
  • the hot strip 7 runs out of the third roll stand 3 with a thickness of 5.0 mm, while it has the thickness of 3.4 mm behind the fourth roll stand 4 and the final thickness of 2.5 mm behind the fifth roll stand 5.
  • only the two roll stands 1 and 2 work with profile control 8, 13 and 9, 14, while the roll stand 3 is already set up for operation with flatness control 10 ', 15' and also the roll stands 4 and 5 with flatness control 11, 16 and 17 work.
  • this can be run essentially without strip profile control, but with flatness control in order to obtain a finished rolled strip with high strip profile and strip flatness quality with a thickness of, for example, 0.3 mm.
  • FIG. 4 The end section of a hot strip tandem mill shown in FIG. 4, which here comprises, for example, seven stands, consists of stands 62 with the order numbers F1-F7. All scaffolds 62 are equipped with devices and adjusting means for adjustment, thickness control, Balance and bend equipped. Each stand 62 has two support rolls 60 and two work rolls 61 in a known manner. The adjusting devices for balancing and bending the work rolls 61 are accommodated in blocks 63, which are fixed to the stand and seen in the rolling direction, in front of and behind the work rolls 61, arranged in the roll stand 62, while the thickness control is effected via the adjusting device 64.
  • Each stand 62 of the F1-F7 series has control devices 21, 22, 23, 24, 25, 26 and 27 for issuing the control commands for balancing and bending the work rolls 61, control devices 31, 32, 33, 34 , 35, 36 and 37 for issuing the control commands for shifting the work rolls 61 in the axial direction and control and regulating devices 41, 42, 43, 44, 45, 46 and 47 for issuing the control commands for setting and regulating the thickness of the roll set 60, 61 assigned.
  • a computer 40 which calculates and monitors the control values for the entire road, is upstream and superior to the control and regulating devices for employment and thickness control 41-47 via a common control rail in a known manner.
  • the control and regulating devices 51, 52, 53, 54, 55, 56 and 57 which are assigned to the respective rolling stands of the F1-F7 series as independent devices, influence the control devices already mentioned for balancing and bending as well as the adjustment for the profile control and thickness control, ie, the control and regulating device 51, the control and regulating devices 21 and 41, etc.
  • the control and regulation takes place according to a model specification (setpoint) of the profile, which the computers 51-57 via a common setpoint rail is specified by the computer 50.
  • the rolled profile of the strip with the profile measuring device 58 and its flatness checked with a flatness measuring device 38.
  • the profile measuring device 58 forwards the determined measurement result to the computer 50, which compares the actually rolled profile with the specified profile model and, if necessary, forwards corresponding correction instructions for conversion into control commands for the roll stands to the independent control and regulating devices 51-57.
  • the measurement result determined by the flatness measuring device 38 is fed to the flatness computer 30, which, if necessary, passes on corresponding correction commands to the control and regulating device 57 for the rolled profile, which are assigned to the last stand F7 and which are converted into control commands in the control and regulating devices 27 and 47 for Balancing and bending as well as adjustment and thickness control in this (last scaffold) is caused.
  • the computers 40, 50 and 30 are in turn connected to a process computer 70 which, in a known manner, contains the large number of data which have passed through and have been determined, such as thickness, width, weight, temperature, strength and profile, and the decreases, speeds and forces which occur during the rolling, and furthermore compares the roll diameter and flattening as actual values with empirical target values and, if necessary, forwards corresponding correction instructions to the computers 40, 50 and 30.
  • a process computer 70 which, in a known manner, contains the large number of data which have passed through and have been determined, such as thickness, width, weight, temperature, strength and profile, and the decreases, speeds and forces which occur during the rolling, and furthermore compares the roll diameter and flattening as actual values with empirical target values and, if necessary, forwards corresponding correction instructions to the computers 40, 50 and 30.
  • a profile measuring device 59 can be arranged behind the third stand F3, which is connected to the profile computer 50 either alone or in addition to the already mentioned profile measuring device 58 behind the last stand F7. If only the profile measuring device 59 is arranged behind the third stand F3, then there is a shortening and thus a more dynamic behavior of the control loop, as well as the possibility of making minor possible corrections in the stands F4-F7 following the stand F3.
  • the profile of the rolled strip is additionally measured again, as described, by a profile measuring device arranged behind the last stand F7 of the road, then a comparison of the two measuring results of the profile measuring device 59 and the profile measuring device 58 also enables conclusions to be drawn about the state of the Pull the mill stands yourself, since a comparison of the actual profiles determined by the two profile measuring devices with the given model profile can have the result that the model profile can no longer be reached from a control point of view and the causes for this can lie in the street itself (roller wear, irregular wear, etc. ),
  • Fig. 6 shows that when such finished strips are rolled out, the cross-flow of the material (spreading) in the first two stands F1 and F2 is very large, then already decreases in stand F3, and that only in stand F4, especially in stands F5 to F7 still slight, does not significantly affect the profile flowing corrections are possible.
  • the cheapest (or the cheapest combination among the known adjustment means) must be selected taking into account the required adjustment range.
  • the adjustment of the roll gap in the stand can be slightly corrected in order to take advantage of the material flow that is still present at right angles to the rolling direction, even with small strip thicknesses.
