- the invention relates to a method for operating an annealing furnace for annealing a metal strip.
- EP 2 742 158 B1 discloses a method for operating a continuous annealing line for processing a metal strip.
- a model predictive control is proposed in which at least one property of the metal strip is input to a computerized model, and wherein the input relates to a point or portion of the metal strip before or in the conti anneal.
- at least one material property of the rolling stock is simulated according to the Conti-Glüh process. This simulated material property is compared to a predetermined setpoint.
- at least one process variable for example the temperature or the speed of the metal strip, is regulated by a regulating device during the conti-annealing process.
- the regulation of the material properties of a metal strip to a desired desired material property requires a lot of computer power and computing time.
- the regulation is effected by an interactive modification of process parameters, temperature and / or speed such that the desired material properties for the metal strip result therefrom.
- the increased computing time is disadvantageous because it results in a reduction of the possible calculation cases or iteration steps.
- the invention has for its object to develop a known method for operating a Glühofen for annealing a metal strip in terms of improving product quality and increasing the output.
- the calculation and specification of a target temperature distribution and / or a target speed of the metal strip in the annealing furnace is carried out so that the metal strip after leaving the annealing furnace having desired desired material property.
- the presence of this desired desired material property is not monitored in the context of the claimed in claim 1 method - unlike a control -;
- no comparison of the desired desired material property with a measured actual material property of the metal strip takes place behind the exit of the annealing to form a material property control difference and no control of this control difference to zero takes place.
- the term "temperature distribution” refers in each case to a section of the metal strip, but in the context of the present description, the term “temperature distribution” also implies a singular temperature value at a specific point of the metal strip.
- annealing furnace includes not only heating devices but also cooling devices downstream of the heating devices in the direction of flow Furthermore, within the scope of the claimed control, there is no feedback of a process variable, which overall increases the output.
- the claimed method may perform a desired self-correction or self-adaptation.
- the actual material property of the metal strip is measured after passing through the annealing furnace, and there is a comparison temperature distribution and / or a comparison speed of the metal strip in the annealing furnace by means of the computer-aided model of the annealing furnace as a function of the measured actual material property and information provided about the metal strip before or in the annealing furnace.
- the method of claim 1 for setting a temperature distribution and / or the speed of the metal strip in the To carry out annealing furnace with the only difference that the actual measured material property of the metal strip is fed after passing through the annealing furnace as an input to the computer model instead of the desired material property.
- the output variables of the computer-aided model are called comparison variables in this case, in this case specifically the comparison temperature distribution and / or the comparison speed.
- the actual temperature distribution and / or the actual speed of the metal strip in the annealing furnace are recorded as actual quantities and compared with the previously calculated comparison variables.
- a non-zero deviation for the temperature distribution and / or the velocity of the metal strip in the annealing furnace may result.
- an adaptation value calculation unit at least one suitable adaptation value is subsequently calculated on the basis of the said deviations.
- the computer model is then subsequently adapted using the calculated adaptation value.
- the above-described method according to the invention for operating an annealing furnace is then carried out for future metal strips, preferably with the adapted computer-aided model. This then results in optimized target temperature distributions and / or desired speeds for the metal strip, which are adjusted by means of a furnace control as an actuator in the annealing furnace.
- the computer model can be z. B. with an empirical database or with a statistical model or with stored glow curves and is therefore suitable for any type of steel. Especially with newly developed steel grades, this model can be used immediately. In contrast to a physical model, which must first be implemented for each new type of steel, the statistical model used according to the invention is easier to generate.
- the adaptation of the computer-aided model does not take place during the passage of the metal strip through the annealing furnace, based on its measured or simulated actual material property, the calculation of the at least one adaptation value or the adaptation of the computer-aided model was carried out. Instead, the adaptation preferably takes place only for future glowing metal bands.
- material properties of the metal strip means, for example, the yield strength, the tensile strength, the elongation at break or the uniform elongation of the metal strip after passing through the annealing furnace.
- information about the metal strip includes, for example, its tensile strength and / or yield strength before a continuous galvanizing line CGL, before a continuous annealing line CAL, in a pickling line or in front of a reel
- composition of the material in particular the steel of the metal strip, further in particular its carbon content and / or

- FIG. 1 illustrates the method according to the invention for operating an annealing furnace 200.
- metal strip 100 is annealed as it passes through the annealing furnace in the direction of the arrow.
- the core element of the method according to the invention is the calculation of a desired temperature distribution Tsoii and / or a desired velocity V SO II for the metal strip in the annealing furnace. This calculation is carried out with the aid of a computer-aided model 220 of the annealing furnace as a function of a predetermined desired desired material property ME SO II of the metal strip and in dependence on information E via the metal strip.
- the Information relates to properties of the metal strip in front of or in the annealing furnace 200 or they concern information about previous processing steps in the production of the metal strip.
- properties of the metal strip in front of or in the annealing furnace 200 or they concern information about previous processing steps in the production of the metal strip.
- the corresponding values are output to an oven controller 230 as an actuator and realized by it in the annealing furnace 200.
- Said setting of the target temperature distribution and / or the target velocity V SO II of the metal strip in the annealing furnace is carried out with the aim of the actual material property ME
- the calculation of the setpoint temperature distribution T SO II and / or the setpoint speed Vsoii of the metal strip in the annealing furnace takes place as long as at least one point or a section of the metal strip to which the said target material property ME SO II of the metal strip relates before or in the annealing furnace.
- the computerized model 220 may be used in calculating the target temperature distribution Tsoii in the annealing furnace 200 and / or calculating the target velocity V SO II at which the metal strip passes through the annealing furnace 200 to an empirical database, a statistical model, and / or fall back on deposited glow curves.
