Definitions

  • the invention relates to a method for setting drive loads for a plurality of drives of a rolling mill for rolling rolling stock, wherein the rolling mill has a plurality of rolling stands and at least one drive for driving the work rolls comprised by the respective rolling stand is associated with each rolling stand, the drive loads being based on an operation of the rolling mill according to a first pass schedule are set to a first setpoint substantially.
  • the invention relates to a control and / or regulating device for a rolling mill and a rolling mill.
  • the invention relates to a storage medium and a machine-readable program code.
  • the present invention is in the technical field of rolling mill technology.
  • the rolling of metallic goods is usually used for the production of semi-finished products, which are subsequently used in the metalworking industry, for example in the automotive industry.
  • a rolling mill must be able to produce a wide variety of metallic semi-finished products, which differ, for example, in the metal to be processed, in the structural properties of steel to be processed and in the spatial dimensions, in particular the thickness.
  • Such a change of the rolling operation has particular effects on the distribution of the drive loads for the drives of a rolling train.
  • the drive loads depend on the thickness reductions of the rolling stock taking place on the rolling stands, the temperature of the rolling stock to be rolled, the type of rolling stock, ie, steel, copper, etc.
  • the Korean Patent Publication KR 2003004835-A discloses a method for automatically adjusting a load distribution for a continuous rolling mill. In this case, set values for the load distribution, which are to be achieved when achieving the desired outlet thickness.
  • the object of the present invention is to carry out an improved method for carrying out a redistribution of drive loads in a rolling train, as well as to provide a corresponding control and / or regulating device, a program code, a storage medium and a rolling mill for this purpose.
  • the procedural part of the object is achieved by a method of the type mentioned above, wherein the drive loads are set in the direction of a second, based on a different second pass plan from the first pass plan target value during rolling, wherein at least during the setting of the second set values an inlet velocity of the Walzguts is set in the rolling train in response to a discharge speed of the rolling stock upstream in the mass flow direction of the rolling mill unit.
  • the second setpoint for the drive load for the respective drive is different from the first setpoint for the drive load of this drive.
  • a portion of the drives of the mill train may receive a second set point based on the second pass schedule that is not significantly different from the amount of the first set point. This is special in the case of drives to rolling mills, which are at the beginning of the rolling train and may not experience any change in the drive load.
  • the inlet velocity to be set serves as a fixed, not arbitrarily adaptable input variable for the rolling train, which in particular is not influenced 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 in the rolling train of a discharge speed of the rolling stock of one or more units dependent, which are preferably arranged upstream of the rolling mill in the mass flow direction.
  • 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 the process, as the other units in occurring in these units process changes.
  • This aggregate with the least dynamic time is usually the limitation with respect to the change in the inlet speed of the rolling mill. Because this may no longer technically follow relatively quickly occurring changes in the inlet speed of the rolling mill.
  • An aggregate is a device which processes or produces a rolling stock in a rolling plant which is in direct or indirect operative connection with the rolling train. Examples include reel, furnace, rolling stand, caster, scissors, descalers, cooling section, etc.
  • the entry velocity is usually a variable manipulated variable with which, for example, to mass flow fluctuations or Bandzugschwankept in the rolling train - caused by the change in the operation of the rolling mill - is reacted. This can be used to correct the deviations in process variables, such as the mass flow, caused by the change in the drive loads.
  • the change in the inlet velocity propagates to the mass flow direction upstream aggregates of the rolling train.
  • this can lead to significant problems in the process of running on the running in the mass flow direction of the rolling mill units running processes. It can lead to undesirable process slowdowns to generate waiting times to avoid rolling collisions, e.g. come in "batch mode" up to process interruptions for in mass flow direction of the rolling mill upstream units.
  • 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.
  • "to a lesser extent” means that the process of the aggregate upstream of the rolling train in the mass flow direction is only influenced by the change in the intake speed in such a way that the aggregate can cope with this process influence and no process interruption or process error occurs on this aggregate.
  • the units arranged upstream of the rolling train in the direction of mass flow can be operated according to their desired values, without a correction of the desired values due to in Mass flow direction downstream processes, such as due to a load redistribution in the rolling mill, is required.
  • the mass flow turbulences in the rolling train caused by the drive load redistribution can be completely cascaded out in the mass flow direction. That it is not necessarily a cascading against the mass flow direction - as usual today - required.
  • the feed rate of the rolling stock in the rolling train during the change of the drive loads so retroactively changed upstream in the mass flow direction processes that they can follow the change in the feed rate in the rolling train control technology still sufficiently fast, i. there is no irreversible process disturbance of the aggregates upstream of the rolling train in the direction of mass flow.
  • the time dynamics of the sluggest of the rolling train in the mass flow direction upstream aggregate is taken into account, i. how fast and to what extent this unit can react to changes in the process without causing irreversible process disturbances.
  • the present invention is applicable to both hot rolling and cold rolling of metal strips.
  • 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.
  • the rolling mill upstream processes hereby particularly simple advantages of the invention can be achieved.
  • This is particularly advantageous in cast roll composite systems, since the casting speed is usually constant and the casting unit is usually the aggregate with the least dynamic in time.
  • this is also advantageous in rolling plants whose aggregates are technically coupled together by the rolling stock, i.
  • the rolling stock for example, is formed in one piece from a casting unit to a reel which winds up a hot strip.
  • 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.
  • a stitch plan usually indicates the thickness reductions and peripheral speeds of the work rolls for the respective rolling stands of the work rolls. If the thickness decrease for a rolling stand, then inevitably the entire Stitch plan of the rolling mill changed. Either the change in the thickness decrease on a roll stand is to be taken into account by this subsequent roll stand, in order to provide a constant outlet thickness from the rolling train, or by changing the pass scheme a targeted change in the outlet thickness of the rolling train. In both cases, this has a direct effect on the drive loads of the drives assigned to the respective rolling stands.
  • the rolling stock is rolled during operation of the rolling mill according to the first pass schedule and operation according to the second pass schedule to the same outlet thickness.
  • the method is carried out in time after a transfer made during the rolling of rolling stock in the rolling train from a first outlet thickness of the rolling train to a different from the first outlet thickness second outlet thickness of 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 suitable both for a thinner outlet thickness and a thicker outlet thickness for transfer and vice versa.
  • the invention can be used particularly advantageously if initially an outlet thickness is used according to a first stitch plan, then a change in the outlet thickness of the rolling train is carried out on the basis of a second stitch pattern during rolling.
  • the second stitch plan is calculated in such a way that it can be easily transferred from the first outlet thickness to the second outlet thickness. If the second outlet thickness is set, a further stitch plan change is preferably carried out directly in such a way that the drive loads of the drives of the rolling train are optimized for the stationary operation of the rolling train at the outlet thickness according to the second pass schedule.
  • the second pass schedule is transferred to a third pass schedule.
  • the second stitch plan corresponds to the first stitch plan mentioned in claim 3 and the third stitch plan corresponds to the second stitch plan mentioned in claim 3.
  • the method is applicable, provided that the rolling train and at least one of the rolling mill in the mass flow direction upstream unit are coupled by the rolling production technology.
  • the reaction to a change in the inlet velocity due to the load redistribution of the drives in the rolling train is particularly drastic. Due to the rolling stock, the change of the inlet velocity transferred directly to the rolling mill upstream in the mass flow direction unit and thus disturbed the running on this unit process.
  • the present invention is particularly advantageously applicable to a cast roll compound plant which is preferably in an "endless” operation, i. it will be continuously cast and rolled, operated.
  • the device-related part of the object is achieved by a control and / or regulating device for a rolling mill comprising a multi-stand rolling mill, with a machine-readable program code having control commands, which in its execution, the control and / or regulating device for performing a method according to one of Induce claims 1 to 4.
  • the object is achieved by machine-readable program code for a control and / or regulating device for a rolling mill, wherein the program code has control commands that cause the control and / or regulating device for carrying out the method according to one of claims 1 to 4.
  • rolling mill with a multi-stand rolling mill for rolling metallic rolling, with a control and / or regulating device according to claim 5, with a device for supplying the discharge speed of the rolling stock of the rolling mill in the mass flow direction upstream aggregate to the tax - And / or control device according to claim 5, wherein the rolling stands the rolling mill with the control and / or regulating device are operatively connected.
  • rolling plant is understood to mean any plant which comprises a rolling train, preferably for processing metallic rolling stock, in particular cast roll composite systems.
  • the rolling train is a high-reduction mill downstream of a casting unit in the mass flow direction and / or a finishing train.
  • a high-reduction mill is a rolling mill consisting of several stands in the present case, which rolls the rolling stock with a large decrease in thickness while it is still very hot. It can be differentiated between Liquid Core Reduction and Soft Core Reduction. As a rule, liquid core reduction in a high-reduction-mill is not used, but the soft core reduction of the rolled stock is certainly applicable. Soft core reduction means that the core of the rolling stock is already solid, but still very soft due to the high temperature of, for example, 1200 ° C to 1300 ° C.
  • the rolling train can alternatively or additionally be formed as a multi-stand finishing train, which rolls rolling to desired final dimensions.
