Definitions
- the invention relates to a method for operating an annealing furnace for annealing a metal strip.
- German patent application DE 10 2013 225 579 A1 discloses a method for controlling or regulating a 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 meter cooperate in a control loop of an automated process control.
- the published patent teaches that the meter is arranged in the material processing direction behind the annealing furnace and recorded online a measured value, which represents a mechanical material property of the strip material. This measured value is then subsequently transmitted to the control unit.
- European Patent Specification EP 2 742 158 B1 discloses a method for operating a continuous annealing line for processing a rolling stock, in particular a metallic strip.
- the method provides that at least one property of the rolling stock relative to at least one point or at least a portion of the rolling stock is supplied as input to a computer-aided model.
- the said point or section is located in front of or in the continuous annealing zone.
- at least one material property of the rolling stock after the continuous annealing process is simulated on the basis of the input variable.
- the simulated material property is compared with a predetermined setpoint. If the simulated material property deviates from the setpoint, at least one process variable, For example, the temperature regulated, as long as the at least one point or portion of the rolling stock is before 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, when passing through preliminary processes, typically experiences fluctuations in its material property over its strip length. These fluctuations also affect the annealed band.
- the present invention seeks to provide an alternative method of operating a furnace for annealing a metal strip in order to largely eliminate the said variations as far as possible.
- This object is achieved by the method claimed in claim 1.
- the subject matter of the method according to the invention is a known regulation for the temperature distribution of a metal strip with the aid of an annealing furnace.
- the invention aims to specify a desired temperature distribution for said control.
- the specification of the desired temperature distribution according to the invention provides the following sub-steps:
- band data of the metal strip to be annealed Selecting a distribution of the actual material properties of the metal strip over its strip length before it enters the annealing furnace from a plurality of deposited or adapted actual material properties on the basis of the strip data; and selecting the desired temperature distribution for the metal strip over its strip length to be prescribed for the regulation as the desired temperature distribution for the metal strip associated with the selected actual material property of the metal strip.
- the band data is at least the steel quality and the thickness of the metal strip at the entrance of the annealing furnace, preferably in addition to its chemical composition.
- pre-process data may be used to select the distribution of the actual material property of the metal strip along its length in addition to the strip data.
- the selected distribution of the actual material property reflects the reality better than the selection of the actual material properties without consideration of the pre-process data. Due to the more precise distribution of the actual material property, the associated desired temperature distribution for the metal strip can be selected more realistically. In turn, an even better selection and design of the desired temperature distribution is possible to compensate for the variations 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 band data-and optionally also in addition to the pre-process data-also measurement data on the material properties of the band for selecting the distribution of the actual material properties of the metal band be used.
- each predefined distributions of the actual material properties of the metal strip z. B. are stored in a database.
- the previously mentioned embodiments aimed to make the best or most realistic selection from the deposited distributions of the actual material properties of the metal strip.
- the deposited distributions of the actual material properties of the metal strip do not map the reality accurately enough, according to a further exemplary embodiment of the invention it is also possible for the deposited distribution of the actual material properties for use for subsequent strips to be targeted to the property of the currently annealed one Metal band to adapt.
- the adaptation takes place on the basis of the belt data and the process data from the furnace and with additional consideration of the measurement data on the material properties of the currently annealed strip, between the output of the annealing furnace and the entrance to the mill stand (M2) and / or at the output of a stretching device (M3) are measured.
- the distribution of the actual material properties adapted in this way can then be used for subsequent bands which are considered to be similar according to a suitable criterion.
- the selection of the target temperature distribution to be prescribed for the control then takes place on the basis of the adapted course of the actual material properties of the metal strip on the basis of a corresponding / predetermined assignment.
- the adaptation can also with additional consideration of pre-process data, the degree of metal strip passing through the annealing furnace downstream rolling mill, the degree of stretching of the metal strip when passing the stretching device of the measured actual material properties of the metal strip at the entrance of the annealing furnace and / or take additional account of the measured material properties of the metal strip after its entry into the annealing furnace.
- Figure 1 shows a classic control circuit for the temperature distribution in one
- FIG. 2 shows the determination according to the invention of a desired temperature distribution for the temperature control according to FIG. 1 according to a first variant; and
- FIG. 3 shows the determination of a desired temperature distribution for the
- 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.
- resulting from the measurement St is compared in a comparator 120 with a predetermined target temperature distribution T SO II of the metal strip 200 over its length.
- a control deviation e possibly resulting from the comparison or subtraction is fed as input to a controller 130.
- the controller 130 calculates an actuating signal Tsteii 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 SO II regulated.
- the temperature control 100 and in particular the measuring device 1 10 are drawn in Figure 1 outside of the annealing furnace; However, they can of course also be arranged inside the annealing furnace.
- FIG. 2 illustrates the method according to the invention for determining a suitable setpoint temperature distribution for the metal strip over its length as input variables for the temperature control of the annealing furnace according to FIG. 1.
- FIG. 2 illustrates the determination of the desired temperature distribution according to a first variant; A second variant will be described below with reference to FIG. First of all, however, the second variant according to FIG. 2 will be described.
- This second variant provides in a minimal configuration that initially band data of the metal strip 200 to be annealed are specified.
- the band data is at least its steel grade and its thickness at the entrance of the annealing furnace, and preferably in addition to its chemical composition.
- the selection of a realistic distribution of the actual material properties of the strip 200 over its strip length before its entry into the annealing furnace from a plurality of stored actual material properties is initially carried out only on the basis of the strip data.
- that target temperature distribution for the metal strip is selected or determined over its strip length, which is assigned to the previously selected actual material property of the metal strip.
- the selected temperature distribution Tsoii for the metal strip selected in this way serves as an input quantity or desired value specification for the temperature control according to FIG. 1.
- pre-process data for selecting the distribution of the actual material properties of the metal strip are also used. This is particularly useful if the metal strip was subjected before its entry into the annealing furnace at least one of the following preliminary processes.
- the preliminary processes it may, for. Example, the 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 act.
- the additionally considered pre-process data can be, for example: the temperature profile of the metal strip in the hot strip mill, the velocity profile of the metal strip in the pickling line, the course of the force in the stretch rectifier, the thickness of the metal strip at the inlet and at the exit of the metal strip Hot strip mill and / or the degree of reduction, for example, the cold rolling degree of the metal strip during cold rolling.
- the measurement data are measurement data measured on the metal strip 200.
- the claimed method comprises a calculation step in order to select the most suitable profile of the actual material properties of the metal strip over its length from the strip data and optionally with additional consideration of the pre-process data and / or the measured data.
- the calculation rule according to the invention can be designed to make a decision on the basis of the data mentioned for a specific deposited actual material property distribution of the metal strip over a strip length.

- FIG. 3 shows a second variant for determining as realistic as possible distributions of the actual material properties of the metal strip. Specifically, this second variant provides that the deposited distributions of the actual material properties of the metal strip are adapted before their selection for the assignment of the desired temperature distribution to adapted curves for the actual material properties of the metal strip.
- the adaptation is based on the belt data and the process data from the furnace as well as taking into account the measurement data on the material properties of the metal strip, which were measured between the exit of the annealing furnace and the entry into the mill stand at measuring point M2.
- the data measured at the measuring point M3, ie the data at the output of the stretching device can also be used be used on the material properties of the metal strip for the adaptation of the deposited distributions of the actual material property for subsequent metal strips.
- the selection of the desired temperature distribution to be prescribed for the control then takes place on the basis of the adapted course of the actual material properties.
