Definitions

  • the invention relates to a method for operating an annealing furnace for annealing a metal strip.
  • German laid-open publication discloses DE 10 2013 225 579 A1 a method for controlling an annealing furnace for metal material in a production line.
  • the production line comprises an annealing furnace and at least one measuring device which is suitable for detecting at least one material property of the strip material to be treated in the production line.
  • the annealing furnace and the measuring device work together in a control loop of an automated process control.
  • the published patent teaches that the measuring device is arranged behind the annealing furnace in the material processing direction and records a measured value online which represents a mechanical material property of the strip material. This measured value is then transmitted to the control unit.
  • the European patent application EP 2 557 183 A1 and the European patent specification EP 2 742 158 B1 disclose a method for operating a continuous annealing mill for processing a rolled material, in particular a metallic strip.
  • the method provides that at least one property of the rolling stock related to at least one point or at least a section of the rolling stock is fed as an input variable to a computer-aided model.
  • the point or section in question is located in front of or in the continuous glow.
  • at least one material property of the rolling stock is simulated based on the input variable according to the continuous annealing process.
  • the simulated material property is compared with a specified target value. If the simulated material properties deviate from the target value, at least one Process variable, for example the temperature, as long as the at least one point or section of the rolling stock is in front of or in the continuous annealing.
  • a method for operating an annealing furnace is based on the problem that a metal strip of a certain steel grade typically undergoes fluctuations in its material properties over its strip length when passing through preliminary processes. These fluctuations also affect the annealed strip.
  • the European patent application EP 2 287 345 A1 discloses a method for operating an annealing furnace for annealing a metal strip, comprising the following steps: specifying a target temperature distribution for the metal strip over its strip length; and regulating the actual temperature distribution for the metal strip over its strip length to the predetermined target temperature distribution in the annealing furnace.
  • the invention has for its object to provide an alternative method for specifying a target temperature distribution for temperature control in an annealing furnace in order to largely eliminate the said fluctuations in the material properties of an annealed metal strip.
  • the subject of the method according to the invention is a known control for the temperature distribution of a metal strip using an annealing furnace.
  • the claimed specification of the target temperature distribution provides the following sub-steps according to the invention: Specification of strip data in the form of at least the steel grade and the thickness of the metal strip to be annealed at the entrance to the annealing furnace.
  • the strip data is at least the steel grade and the thickness of the metal strip at the entrance to the annealing furnace, preferably also its chemical composition.
  • preliminary process data can also be used to select the distribution of the actual material properties of the metal strip over its length.
  • the distribution of the actual material properties selected in this way reflects reality better than the selection of the actual material properties without taking the pre-process data into account. Due to the more precise distribution of the actual material property, the assigned target temperature distribution for the metal strip can also be selected more realistically. This in turn enables an even better selection and design of the target temperature distribution to compensate for the fluctuations in the material properties of the strip.
  • the selection process for the distribution of the actual material properties can be represented even more realistically if, in addition to the strip data - and optionally also in addition to the pre-process data - also measurement data about the material properties of the strip for selecting the distribution of the actual material properties of the metal strip be used.
  • predefined distributions of the actual material properties of the metal strip for. B. are stored in a database.
  • the previously mentioned exemplary embodiments aimed to make the best or most realistic selection from the stored distributions of the actual material properties of the metal strip.
  • the stored distributions of the actual material properties of the metal strip do not yet sufficiently reflect reality, then according to a further exemplary embodiment of the invention there is also the possibility of specifically targeting the stored distribution of the actual material properties for use by subsequent strips to the properties of the currently annealed one Adapting the metal strip.
  • the adaptation takes place on the basis of the strip data and the process data from the furnace as well as taking into account the measurement data on the material properties of the strip that is currently annealed, between the exit of the annealing furnace and the entrance to the rolling stand (M2) and / or at the exit of a stretching device (M3) can be measured.
  • the distribution of the actual material properties adapted in this way can then be used for subsequent belts, which are considered to be similar according to a suitable criterion.
  • the target temperature distribution to be specified for the control is then selected on the basis of the adapted profile of the actual material properties of the metal strip on the basis of a corresponding / predetermined assignment.
  • the adaptation can also take into account preprocessing data, the degree of skin pass of the metal strip as it passes through the rolling stand downstream of the annealing furnace, the degree of stretch of the metal strip as it passes through the stretching device, the measured actual material properties of the metal strip at the entrance to the annealing furnace and / or below take into account the measured material properties of the metal strip after it has entered the annealing furnace.
  • the control circuit comprises a measuring device 110 for measuring the actual temperature distribution of the metal strip over its strip length, preferably in the annealing furnace.
  • the actual temperature distribution T actual resulting from the measurement is compared in a comparator device 120 with a predetermined target temperature distribution T target of the metal strip 200 over its length.
  • a control deviation e possibly resulting from the comparison or the formation of the difference is fed to a controller 130 as an input variable.
  • the controller 130 calculates an actuating signal T Stell for a heating device in the annealing furnace, which, in terms of control technology, serves as an actuator for adjusting the temperature distribution in the metal strip. In this way, the temperature distribution of the metal strip to the predetermined Target temperature distribution T target regulated.
  • the temperature control 100 and in particular the measuring device 110 are in fact Figure 1 drawn outside the annealing furnace; however, they can of course also be arranged inside the annealing furnace.

  • Figure 2 illustrates the determination of the target temperature distribution according to a first variant; a second variant is described below with reference to Figure 3 described. First, however, the second variant is according to Figure 2 described.
  • this second variant provides that strip data of the metal strip 200 to be annealed are initially specified.
  • the strip data is at least its steel grade and its thickness at the entrance to the annealing furnace, and preferably also its chemical composition.
  • the selection of a distribution of the actual material properties of the strip 200 as realistic as possible over its strip length before it enters the annealing furnace from a plurality of stored actual material properties is initially only based on the strip data.
  • the desired temperature distribution for the metal strip over its strip length that is assigned to the previously selected actual material property of the metal strip is subsequently selected or determined.
  • the target temperature distribution T target thus selected for the metal strip serves as an input variable or target value specification for the temperature control Figure 1 .
  • preprocessing data are also used to select the distribution of the actual material properties of the metal strip. This is particularly useful if the metal strip was subjected to at least one of the following preliminary processes before it entered the annealing furnace. In the preprocesses, it can e.g. B. hot rolling of the metal strip in a hot strip mill and / or the pickling of the metal strip after hot rolling and / or the cold rolling of the metal strip after pickling.
  • the pre-process data that is also taken into account can be, for example: the temperature profile of the metal strip in the hot strip mill, the speed profile of the metal strip in the pickling line, the profile of the force in the stretcher, the thickness of the metal strip at the entrance and exit of the Hot strip mill and / or by the degree of reduction, for example the degree of cold rolling of the metal strip during cold rolling.

  • Figure 3 shows a second variant for determining the most realistic possible distributions of the actual material properties of the metal strip.
  • this second variant provides that the stored distributions of the actual material properties of the metal strip are adapted prior to their selection for the assignment of the target temperature distribution to adapted courses for the actual material properties of the metal strip.
