Definitions

  • the invention relates to a method for cold rolling metallic strip according to the preamble of claim 1.
  • the invention can be used for example for the production of strips from iron and non-iron alloys.
  • FIG. 3 shows the time profiles of variables of interest - such as the deviation on the outlet side, the rolling force, the inlet and outlet side belt speeds, the circumferential roller speed and the speed of the inlet-side reel - on the belt header.
  • variables of interest - such as the deviation on the outlet side, the rolling force, the inlet and outlet side belt speeds, the circumferential roller speed and the speed of the inlet-side reel - on the belt header.
  • the very strong thickness deviations on the outlet side can be clearly recognized during the initial phase of cold rolling.
  • Both Figures 3, 4 show a much higher rolling force level in the area of the disturbances (fluctuations), which cannot be explained by better lubrication in the roll gap at a higher speed.
  • the frequency of the adverse fluctuations that occur corresponds to the speed of the reel on the inlet side.
  • the amplitudes drop - depending on the case under consideration - band head piece or band end piece - or rise sharply.
  • the wavelength of the thickness deviations depends on the circumference of the reel on the inlet side, extended by the ratio between the strip thickness on the inlet side and the outlet side.
  • Fig. 5 shows a sketch to explain the physical causes of the "Christmas tree effect occurring at the band head.
  • the explanation for the" Christmas tree effect "occurring at the band head is that the coil in a storage device with the hot-rolled band is not uniform across the entire volume, but cools asymmetrically. Heat is removed from the coil more quickly and more intensely than through the outer jacket surfaces of the coil, which are only “flushed with air", via the contact surfaces of the coil with the bearing device. In this way, zones of different temperature are formed after hot rolling across the cross section of the coil, as the left section of FIG. 5 shows.
  • the temperature of the strip falls below the recrystallization temperature in sections, which leads to strong fluctuations (variations, deviations from the desired value) in the hardness as a function of the strip length in the strip, that is to say in the strip head piece before cold rolling, such as the right one Section of Fig. 5 shows.
  • the exact profile of these fluctuations in hardness depends heavily on the exact conditions and the resulting asymmetrical temperature conditions during storage of the coil.
  • non-uniform recrystallization due to asymmetrical temperature conditions during stress-free annealing can cause similar problems with fluctuating hardness during cold rolling after annealing.
  • the sensitivity of the ratio of strip thickness to hardness fluctuation can vary within a wide range - for example 5 ⁇ m / MPa ... 50 ⁇ m / MPa.
  • the fluctuations in the mass flow and the strip tension are mainly caused by the fluctuations in the strip thickness at the outlet end resulting from the fluctuating hardness.
  • rolling mills with their strip thickness detection devices measure the fluctuations indirectly in terms of hardness with a higher sensitivity than tensile strength tests of selected strip pieces carried out offline, for example.
  • Usual strip thickness detection devices achieve a measuring accuracy in the range of +/- 0.3 ⁇ m.
  • the invention has for its object to provide an improved method for cold rolling metallic strip, with which a fluctuation in hardness is effectively recognized and in particular can be prevented that strip head pieces and strip end pieces with fluctuating strip thickness on the outlet side arise.
  • the advantages that can be achieved with the invention are, in particular, that in order to ensure high quality with regard to the cold-rolled strip, it is of great importance to identify variations (fluctuations) in the hardness of the (for example hot-rolled) entry-side strip as quickly as possible, because this is helpful, in order to be able to master the problems occurring during the cold rolling due to fluctuating hardness and consequently to achieve the high product quality with regard to the strip thickness on the outlet side which is desirable by means of the cold rolling.
  • the hot rolling or annealing and storage conditions of the same strips can also be improved.
  • FIG. 1 shows an arrangement for the identification, detection and compensation of a "Christmas tree effect occurring in a strip due to fluctuating hardness.
  • the figure shows a roll stand suitable for cold rolling with strip winding devices and detection devices (sensors) for important measured values (process signals, variables,
  • a generally known roll stand 1 with upper support roll 2, lower support roll 3, upper intermediate roll 4, lower intermediate roll 5, upper work roll 6 and lower work roll 7.
  • a belt 8 runs through the roll gap formed between the work rolls 6, 7
  • the direction of movement of the strip 8 is indicated by an arrow
  • This strip 8 is unwound from an inlet-side reel (unwinder, decoiler) 9.
  • the strip 8 reaches the roll stand 1 via an inlet-side deflection roller 10 (measuring roller for detecting the strip tension of the inlet-side strip) ,
  • the strip 8 leaves the roll stand 1 and arrives at an exit-side reel (reel, rewinder) 13 via an exit-side strip thickness detection device 11 for detecting fluctuations in the exit-side strip thickness ⁇ h 1 and a return-side deflection roller 12 (measuring roller for detecting the strip tension of the exit-side strip) for winding up the cold-rolled strip.
  • a measuring device 14 serves to record the belt speed v 1 on the exit side.
  • the belt speed v 1 on the exit side can also be estimated with the aid of other measured variables.
  • the fluctuations (variations) in the hardness of the incoming strip cause relatively large disc-side thickness deviations, strip tension fluctuations and rolling force fluctuations with a frequency that corresponds to the speed (or a multiple of the speed) of the input-side reel 9, while at the same time there are typically no significant thickness deviations in the infeed band at such a frequency.
  • the principle of the "Christmas tree effect" detection carried out by means of the identification and detection device 18 now consists in fluctuations (deviations) in the exit-side strip thickness ⁇ h 1 , fluctuations (deviations) in the rolling force F r , fluctuations (deviations) in the strip tension F t0 des incoming strip and fluctuations (deviations) of the strip tension F t1 of the outgoing strip, the frequency of which is equal to the frequency of the speed of the inlet-side reel 9 or the frequency of which is a multiple of the speed of the inlet-side reel 9.
  • This identification and detection can be carried out with the aid of Cross-correlation or Fast Fourier transformation or with the help of a disturbance observer.
  • the profile of the strip tension fluctuations shows impulsive excitations with subsequent vibrations and is in no way purely sinusoidal.
  • the strip tension fluctuations due to local elevations and out-of-roundness of the coil also cause fluctuations in the strip thickness on the outlet side, these thickness deviations are relatively small compared to the thickness deviations due to the "Christmas tree effect".
  • the uncoilings of the harmonics of strip thickness, rolling force and strip tension are determined.
  • a roll force and strip thickness harmonic is calculated using the strip tension harmonic and an online roll gap model. If the measured rolling force and thickness amplitude is greater than the calculated values by a predetermined threshold value and there is no coiling speed dependency, the hardness fluctuation is recognized.
  • the fluctuations (variations) in hardness or the amplitude ratio of the fluctuations in hardness are estimated using an online roll gap model.
  • roller circumferential speeds of the stands are corrected in addition to the support roller position and reel speeds.
  • Compensation monitoring automatically switches the compensation "reel speed correction ⁇ v 0 + reel speed correction ⁇ v 1 + correction signal ⁇ s" to the strip tension controls 16 + 17 and the hydraulic roll gap control 15. If the remaining rolling force fluctuations harmonic flatness fluctuations when cause belt on the outlet side, these effects are compensated for by regulation with feedforward control of the roll bending. In other words, the disadvantageous effect of the rolling force fluctuation on the strip flatness is compensated for by bending pre-control.
