Definitions

  • the invention relates to a method for processing rolling stock in a rolling mill with at least one rolling mill having a drive.
  • the rolling stock passes through a rolling train with one or more rolling stands.
  • the individual rolling stands each have a drive for rollers, with which the rolling stock is rolled into sheets or wires with a desired geometry, such as thickness or cross section.
  • the rollers must be controlled to a certain speed with the aid of the drives of the individual rolling stands. It is also important that during the entire operation of the rolling mill and the predetermined ratio of rotational speeds of the rollers of the individual rolling stands remains constant, otherwise tensile and compressive loads on the rolling occur, which in turn lead to an undesirable rolling result or even tearing or can cause a looping of the rolling stock.
  • each rolling stand with a separate drive for the rolls.
  • the individual drives each have a separate speed control, so that they can be controlled individually.
  • a major challenge of such a drive solution is the speed control of the rollers or drives of the individual rolling stands during the processing of rolling stock. This is especially true when different load moments act on the individual rolling stands, which for example when tapping, i. when striking the rolling stock on the rollers is the case. In such an action of a load torque on the drive, the rollers are braked, which thus leads to a collapse of the rotational speed of the rollers or of the drive to the relevant rolling stand.
  • the rollers of other rolling stands however, on the time of tapping no or a deviant, z. B. acts a smaller load torque, have an unchanged or only slightly changed speed.
  • a rolling mill has at least one rolling mill having a drive in which, in order to reduce a speed drop of the drive caused by a foreseeable load torque acting on the drive, a rolling moment pilot control of the drive takes place by the torque-generating current supplied to the drive.
  • the occurrence of a foreseeable load torque is reduced by a rolling torque pilot control of the torque-generating current supplied to the drive.
  • suitable parameters such as roll gap geometry, position and characteristics of material sensors, distance of the individual rolling stands or roller and material speeds are used, with which it can be determined when the load torque and at what level it acts on the relevant drive.
  • the corresponding values including the amount of the foreseeable load torque can be determined, for example, by means of a model of the rolling mill.
  • the current supplied to the drive can then be selectively controlled in such a way that a reduction in the rotational speed of the drive associated with the occurrence of the load torque is reduced.
  • a controlled operation of the drives or the rollers of the individual rolling stands and thus the entire system is guaranteed. It is therefore no longer to individual tensile or compressive loads due to strong speed fluctuations of the individual drives or rollers of different rolling stands.
  • variations in the thickness are reduced and cracking of the rolling or looping largely avoided. This is especially true when the rolling mill has several rolling stands with separate drives and each drive is individually pre-controlled.
  • the foreseeable load torque is corrected by evaluating the actual values, in particular torque, speed, and derived actual accelerations. This results in a dynamic correction in the position of the tape head.
  • the height of the load torque can be corrected dynamically.
  • an evaluation is made by evaluating the deviation between the precontrol values for the foreseeable load torque and the actual load torque, an iterative optimization for correcting the Aufschaltzeitifiess and an iterative correction of the height of the predictable load torque.
  • the feedforward control is material-based. This means that material parameters such as hardness or influencing factors such as temperature and type of material are initially taken into account, how high the foreseeable load torque acts on the drive in question, so that depending on the drive, the drive is accordingly pre-controlled and thus the supplied current is changed.
  • the current is not leaps and bounds, but increasing, within a time window continuously, in particular increases ramped for pre-control of the drive.
  • the corresponding torque of the drive is changed only relatively slowly, so ramped.
  • the ramp can also be preset in a staircase.
  • the slope of the ramp for the torque is dimensioned such that the drive train remains in a defined and reproducible state at any time.
  • the overall system is better controlled and it shows a much improved timing of the individual drives and in particular the overall system.
  • a reproducibility of the behavior of the entire system is ensured.
  • the limitation of the increase of the current takes place with a corresponding ramp-shaped increase of the current setpoint value and can take place indirectly via a torque or also speed precontrol.
  • the steepness of the ramp depends on the dynamics of the power converter. In this case, type of converter, operating point and the design of the power converter, in particular the amount of current to be impressed, the speed and the voltage reserve play a role. With high reproducibility, the slope corresponds to an average value that can be achieved at the specified operating points. For complete reproducibility, the slope of the ramp or staircase must be smaller than the possible maximum slope that the power converter can provide over all specified operating points. The setpoint increase then does not exceed the achievable dynamics of the converter at the voltage limit at nominal motor voltage and maximum power. This eliminates deviations of the converter behavior in different operating points. This allows extremely accurate and predictable feedforward control at high speeds. The reproducible operation allows a very precise analysis of the inertia by interpolation, in addition a dynamic statement about the occurring load torque for the dynamic correction of the material position and the load height.
  • the ramp is designed such that the increase in torque of the drive achieved by the current increase causes a symmetrically acting deviation, so that the speed increase to the occurrence of the load and the delay after the occurrence of the load cancel until the complete build-up of the torque.
  • the torque input is thus realized halfway before and the other half after the load torque has occurred.
  • Pre-control is completed before the material enters the scaffold when the rise time between the occurrence of the load until complete torque application does not exceed the scaffold spacing divided by material velocity. In the case of a symmetrically acting deviation, this corresponds to twice the time required for the material to pass between two scaffolds.
  • FIG. 1 shows a section of a rolling train 2 with successive rolling stands 4 for processing a rolling stock 6.
  • eight consecutive rolling stands 4 are shown which pass through the rolling stock 6, eg a billet, which is rolled into wire.
  • Each mill stand 4 is a separate drive 8, comprising a motor 10 and a gear 12 associated with, wherein in the figure for clarity, only one drive 8 is indicated.
  • the drive is supplied by means of a power converter 14 with a control unit 16, a desired current I.
  • Each roll stand 4 further comprises at least one roller 13, which is driven by the respective drive 8 at a predetermined speed n, which is taken for example from a pass schedule.
  • the speed of rotation caused by a load torque M L acting on the drive 8 is reduced by the drive 8 with the aid of the control device 16 and the power converter 14 is precontrolled with respect to its supplied current I.
  • the load torque M L can be known or estimated, that is, a predictable size. For example, based on models of the rolling mill 2 as well as known sizes of the rolling stock 6 to be rolled, a corresponding expected value of the load moment M L acting on a drive 8 of a rolling stand 4 can be determined. This expectation value is determined over time so that the load moment M L for a particular drive 8 of a roll stand 4 is predicted over time. Depending on the foreseeable load torque M L , the rolling torque precontrol of the drive 8 is then effected by the torque-generating current I supplied to the drive such that a fall in the rotational speed of the drive 8 is compensated. For drives which, unlike the preferred solution, drive more than one rolling stand 4, the motor-related load torque M L determined over time reflects the sum of the individual motor-related rolling moments.
  • FIG. 2 is now exemplified for two rolling stands 4, each with a drive assigned to this 8, the time course of impinging on them load moments M L and these drives 8 supplied current I with the corresponding control variable, namely the current setpoint shown over time.
  • Curve 18 represents a sudden change of the load torque M L on the drive 8 of the first stand 4 at time t 2
  • curve 20 represents a jump of the load moment M L on the drive 8 of the second stand 4 at time t7.
  • the ramp for the current setpoint and for the current I is dimensioned such that the drive 8 remains in a stable state, which is also reproducible, that is, the increase of the current setpoint and the current I is so slow that the drive. 8 has a defined operating behavior.
  • the ramp of the current I is designed such that the torque increase of the drive 8 achieved by the increase in current is realized to one half before and the other half after the occurrence of the load torque M L. This means that the time span from t 1 to t 2 equals the period from t 3 to t 4 . When the time t 4 is reached, the amount of the load torque M L then corresponds to the amount of the torque M of the drive 8.
  • the current I according to curve 28 in the interval between t 6 and t 9 increases ramped such that the drive 8 remains in a stable state and the increase in torque achieved by the torque increase of the drive 8 to one half before and the other Half after the occurrence of the load torque M L is realized.
  • FIG. 3 now the speed curve of the two drives 8 is shown on the corresponding rolling stands 4.
  • the lower curve 30 shows the time course of the rotational speed n of the drive 8 of the first rolling stand 4.
