Definitions
- the invention relates to a method for process control or process regulation of a plant for the forming, cooling and / or heat treatment of metal, in particular steel or aluminum, the plant being equipped with actuators for setting certain operating parameters and the process being based on a process model.
- Operating parameters are understood to mean, for example, the roll settings in a rolling section or the cooling parameters in a cooling section.
- Microstructure optimizer depending on the desired material properties of the Metal are determined.
- the expected material and usage properties are determined by means of a structure observer. There follows a comparison between target values and the values determined by the structural observer for the material and usage properties. If there is a difference between the observed or calculated and the determined values, the operating parameters such as the inlet and outlet temperature of the rolling section and the degrees of reduction are changed.
- WO 99/24182 also explains the changes in the structure of steel during rolling, while DE 199 41 600 A1 and DE 199 41 736 A1 describe the ⁇ - ⁇ structure transformation of steel in more detail.
- the object of the invention is to provide a method for process control or process control of a system for the forming, cooling and / or heat treatment of metal, in particular steel or aluminum, with which it is possible to obtain desired structural details online and using desired structure-property relationships Target material properties.
- the task is solved by systematically linking the process model, an online recording of at least one current structural parameter, for example at the end of the process to be controlled, and a structural model.
- the prediction models should include a structural model, i.e. a prognosis model for predicting the solid-state reactions taking place during the forming process, for example in the rolling mill, or cooling in the cooling section and the resulting structural features.
- an online adaptation of the method model and / or the structure model should preferably be carried out. If the difference exceeds a certain value in an actual-target value comparison, the process model (for example the pass schedule model or the cooling section model) and the microstructure model are recalculated.
- a current microstructure size value and / or a microstructure transformation time or the microstructure transformation time interval is preferably recorded as the value meaningful for the microstructure.
- the detection of the current structural characteristic value is preferably carried out by means of non-destructive material testing devices, such as by means of ultrasound measuring devices, and here in particular laser-generated ultrasound measuring devices, and X-ray devices.
- Measuring devices that contact the metal should preferably be used to determine the structural change. This includes rolling force measuring devices and measuring rollers for the detection of tensile and tensile stresses on the metal strip during forming. The one with the ⁇ - - Conversion of longitudinal expansion of the metallic steel grid can thus be recorded as a measure of the structural transformation via these touching measuring devices.
- the transformation temperature is recorded online as the meaningful value for the structure by means of at least one temperature detection unit, which is arranged to be relatively movable along the metal conveying direction and depending on the expected location of the structure transformation, which is predicted according to the structure model becomes.
- a plurality of temperature detection units are preferably provided.
- the austenite grain size of the structure of the metal to be processed is predicted at a specific point in the process or at a specific location in the process .
- the current austenite grain size of the metallic structure is recorded online - in this case during a rolling process - behind the last rolling stand of the rolling mill without contact or non-destructive.
- the currently recorded austenite grain size value is compared with a specified target value for the size of the structure's austenite grain at this point in the process.
- a correction value for controlling the actuators of the rolling mill is derived from the difference value, using the microstructure and process model on which the rolling mill is based, and is given to the actuators accordingly. If, for example, the measured austenite grain size is smaller than a target value, a correction value is applied to the actuators for the intermediate stand cooling of the rolling mill in order to reduce the intermediate stand cooling and thus an increase in the To reach the final rolling temperature. By increasing the final rolling temperature, a larger grain size of the austenitic structure is set at the end of the rolling mill. Since even slight changes in the finish rolling temperature have a significant influence on the austenite grain size, the control of the system still affects the metal strip or sheet currently being treated, ie the grain size can still be adjusted to the setpoint on the same strip.
- the current value which is meaningful for the structure, is recorded online during the metalworking process by forming, cooling and / or heat treatment at a specific point, i.e. on the stand (s) or stitch (s) with targeted control of the process parameters for the previous stands (n-1) or stitches (n-1) depending on the actual-target value comparison made.
- the structural grain size of the metal strip or metal sheet is recorded before the forming in the frame (s) of a hot wide strip mill or before the forming in the stitch (s) of a heavy plate mill, for example using an ultrasound device. If the actual value deviates too much from a target value, the process model, in particular the pass schedule model, and the microstructure model are recalculated with effects on the control signals for the actuators of the upstream stands or the actuators for performing the previous stitches, so that the desired target size is achieved can be.
- the changeover of the previous stands can already be done online for the currently rolled strip or sheet and / or can be used for the subsequent strip or sheet.
- an online microstructure control takes place in a cooling section of a wire mill with a water cooling section and an air cooling section, in that an actual microstructure size value, here the austenite grain size, of the metal wire is detected by means of an ultrasound measuring device after passing through the water cooling section and the temperature of the structural transformation as well as the time course of the structural transformation, ie the ⁇ - ⁇ transformation, is recorded with temperature measuring devices that can be moved in the transport direction and / or can be oriented differently. If the recorded values deviate from the planned target values, a new calculation is made using the cooling section and microstructure models, and the actuators of the cooling section are set accordingly online.
- an actual microstructure size value here the austenite grain size
- the proposed online microstructure control or regulation is not only used on hot wide strip, possibly also thin slab rolling, heavy plate, profile, bar steel and wire mills, but also on cold strip and aluminum mills.
