  • Japanese Laid-Open Patent Publication No. 59191509 A2 discloses a method of changing material dimensions during the passage of rolling stock in a continuous rolling mill. In this case, manipulated variables are calculated from an initial state and a position tracking for the
  • Section of the tape for which the thickness is to be changed Accordingly, a roll gap and a rolling speed are set for the respective rolling stand. In particular, it is provided that no reduction in thickness occurs at the last rolling stand.
  • Object of the present invention is to provide an improved method for performing a flying thickness change, and a corresponding control and / or regulating device and rolling mill for this purpose.
  • the procedural part of the object is achieved by a method of the aforementioned type, wherein a transfer takes place during the rolling from the first to the second outlet thickness at an entry speed of the rolling stock in the rolling train, which in dependence of a discharge speed of the rolling stock of the rolling train in the mass flow direction upstream aggregate is set.
  • the determined entry speed serves as a fixed, not arbitrarily adaptable input variable for the rolling train, which is not changed in particular by processes downstream of the first rolling stand of the rolling train in the direction of mass flow. Rather, the entry speed of the rolling stock into the rolling train depends on a discharge speed of the rolling stock of one or more units, which are arranged upstream of the rolling train in the direction of mass flow.
  • the discharge speed is preferably an actual discharge speed of the rolling stock of an upstream unit in the mass flow direction of the rolling mill.
  • a target discharge speed of the rolling stock of an upstream in mass flow direction of the rolling mill unit can be used.
  • the outflow speed of that aggregate of the rolling mill is used, which has the least time dynamics and therefore carrier reacts to changes in its process, as the other aggregates.
  • This aggregate represents the limitation in the flying change of the outlet thickness. Further limitation for the flying change of the outlet thickness can result from the required or possible adjustment paths on the rolling stands and the required or possible acceleration of the work rolls of the rolling stands in the rolling train.
  • outlet thickness is understood to mean the thickness of the rolling stock after the last roll stand of the rolling train; "inlet thickness” is understood to mean the thickness of the rolled stock before the first rolling stand of the rolling train.
  • the method is both suitable to convert a thinner outlet thickness in a thicker outlet thickness and vice versa. In general, however, the change of the outlet thickness to a thinner outlet thickness is technically more demanding than the conversion of a thinner outlet to a thicker outlet thickness.
  • An aggregate is a rolling process to be processed or generating device in a rolling mill, which with the Walz Sounds in indirect or direct operative connection stands. Examples include reel, furnace, rolling stand, caster, scissors, descalers, cooling section, etc.
  • the inlet velocity is usually a variable manipulated variable, which is reacted for example to mass flow fluctuations or Bandzugschwankept in the rolling mill - caused by the change of the operation of the rolling mill - by changing just this manipulated variable.
  • the deviations caused by the transfer in process variables, such as the mass flow can be corrected.
  • the infeed speed of the rolling stock in the rolling train is determined, adjusted and maintained, that an adaptation of a Walzgut-discharge speed of a mass flow direction upstream aggregate on the inlet speed of the rolling train is not required or to a lesser extent is.
  • the units arranged upstream of the rolling train in the mass flow direction can be operated according to their desired values, without a correction of the desired values due to processes downstream in the mass flow direction, in particular due to a transfer of a rolling stock from a first exit thickness to a second exit thickness, is required.
  • the mass flow turbulences in the rolling train caused by the transfer can be completely cascaded out in the mass flow direction. the.
  • the infeed speed which is set as a function of an outfeed speed of the rolling stock of an upstream unit in the mass flow direction of the rolling train, can be handled according to the invention as a hard, to be complied boundary condition of the rolling process.
  • the inlet speed is set substantially constant as a function of an outlet speed of the rolling stock of an upstream unit in the mass flow direction of the rolling train.
  • advantages according to the invention can also be achieved hereby for slowly changing processes preceded by the rolling train. This is particularly advantageous in cast-rolled composite systems, since the casting speed is generally constant and the casting unit is usually the aggregate with the least dynamic response.
  • the invention makes it possible to ensure a constant mass flow on the input side into the rolling mill. This leads to the corresponding planning reliability and a smoother process of the processes, which are upstream of the rolling mill in the mass flow direction.
  • the entry speed is set substantially to the exit speed of a next, upstream of the rolling mill unit.
  • This is particularly expedient, for example, when the distance of the rolled or slabs to be rolled is very low, for example in continuous operation, in conti mode or in semi-endless operation of a rolling plant
  • process control that is undisturbed by the infeed speed of the rolling train becomes aggregates that are upstream of the rolling train in the direction of mass flow possible, in particular, there are no deviations from the desired belt tension or the desired mass flow.
  • the rolling train and at least one in Massenpoundrich- direction of the mill train upstream unit preferably a casting unit, coupled by the production of the first and the second Walzgutabites having rolling stock. That A change of the entry speed, which is not caused by the upstream aggregate, into the rolling train propagates via the rolling stock into the aggregates upstream of the mass flow direction of the rolling mill and thus adversely affects the processes taking place in these aggregates.
  • it is possible that in the mass flow direction of the mill train upstream units are not able to respond to the relatively rapid changes in the inlet velocity, as are common in the art and also required to compensate for mass flow fluctuations during the transfer.

  • this method can be used advantageously in the case of "conti" operation of a rolling train, because there is only one single transfer section, which can be assigned to a flying change in the exit thickness of the rolling train, whereas in batch operation, additional strike losses of rolling stock always occur ,
  • the transfer section is determined such that it at any time during its passage through the rolling train has a length which is at most equal to a distance of two adjacent adjacent rolling mills. This ensures that the flying change of the outlet thickness of the rolling train is technically particularly easy and fast. Namely, if the thickness wedge at the same time in two rolling stands, this means a considerable overhead for the control of the flying change of the outlet thickness. Therefore, it is advantageous to determine the length of a transfer section in such a way that at a certain time during the transfer of the thickness wedge always only in a rolling mill of the Rolling mill is being processed.
  • this condition is met when the length of the transfer section between the last in the mass flow direction and last but one last change in thickness of the rolling stock causing roll stand of WaIz- road is not greater than a distance of these two stands from each other.
  • the length of the transfer section to be determined depends on the number of rolling stands in the rolling train, as well as the inlet thickness of the rolling stock in the rolling train and the desired outlet thickness of the rolling stock from the rolling train.
  • the transfer section is rolled by means of a plurality of roll stands comprised of the rolling train, wherein at least one rolling stand is operated during the rolling of the transfer section as a rolling force-controlled rolling stand.
  • a rolling-force-controlled rolling stand is used to roll the transfer section according to the specifications, the thickness wedge is automatically detected, since the rolling stand changes to a rolling force change due to the changed thickness of the thickness wedge when the transfer section enters the rolling gap.
  • the change in rolling force on the respective rolling stand is dependent on whether the running-in thickness into the respective roll stand becomes lower or higher as a result of the transfer.
  • these are preferably operated position-regulated. With a reduced infeed thickness of the transfer section compared to the preceding rolling stock section processed by this mill stand, when the transfer section enters the nip of this mill stand, the rolling force on this mill stand falls.
  • the rolling force controller is now trying to set the desired nominal rolling force again according to the first pass schedule for this mill.
  • the set rolling force to be set is continuously changed in the direction of the rolling force target value according to the second pass schedule.
  • Stitch plan are set and according to the second stitch plan desired outlet thickness is achieved from the respective rolling stand. This happens for each mill stand of the rolling mill.
  • a transfer of the operation of the rolling stand according to the first is handled in a second pass schedule, in which the first outlet thickness of the rolling line is less than the second outlet thickness.
  • the first outlet thickness of the rolling line is less than the second outlet thickness.
  • Stitch plan for a reduced thickness reduction As a result, it comes when entering the processed through the first rolling stand transfer section in the second and possibly the subsequent rolling stands to a rolling force increase.
  • This rolling force increase can be used to detect the entry of the transfer section into the respective rolling stand.
  • a so-called "ramp in” of the rolling force setpoint according to the second pass schedule is then carried out in the rolling set value according to the first pass schedule during the rolling of the transfer section by the respective rolling mill stand.

  • Examples of process variables which undergo a continuous change during the rolling of the transition section are, for example: setting position, setting force, peripheral speed of the work rolls, acceleration rate, etc. This is particularly advantageous for the above-mentioned change in rolling force during rolling of the transfer section.
  • a continuous transfer i. Non-impact or bumpless change of the process variables, simplifies the handling of WaIz- good for the rolling mill in the mass flow direction downstream units and reduces the load on the system. This can be achieved, for example, with the above-described "ramp in" of a second setpoint variable, a first setpoint size .
  • the setpoint variables are overlaid in such a way that a continuous change takes place from the actual process variable in the direction of the new setpoint process variable.

These can be caused by mass flow turbulences between the rolling mills of the rolling train.
  • a belt tension can be detected, for example, by means of a loop lifter between the individual rolling stands of the rolling train.
  • the employment of the rolling stand to be passed through by the transfer section is now changed.
  • the change of employment may have an adjustment of the roll gap to the goal or a setting of a desired rolling force for the rolling stock. If, for example, a voltage drop is detected, an opening of the roll gap of the rolling stand to be passed next from the transfer section to the strip tension is restored, since more material can thereby be transported through the next rolling stand.
  • the adjustment is closed in order to lower the belt tension between the rolling stand to be passed next from the transfer section and the rolling stand upstream of this rolling stand in the direction of mass flow.
