Definitions
- the present invention relates to a method and a device for setting process parameters of a production process for an elongated flat product in order to achieve a specifiable product quality.
- the surface maps could provide valuable information on where in the production process certain errors were caused, but this could not be automated or systematized.
- the object of the present invention is to systematically check the data obtained by means of a surface inspection system for any
- the correlation should also be able to be used online in production processes, in particular in casting and rolling systems for steel sheets in the hot rolling process.
- an immediate feedback to the production process for regulating the parameters responsible for certain deviations in quality should also be achieved.
- the number of measured values in the exemplary embodiment described here can reach approximately 1,000,000 values per minute.
- the data of a surface inspection system also reach about this size.
- the parameters can be of different types to identify continuous or discrete variables or purely Boolean parameters that can only take two values.
- numerous process parameters of the production process are recorded as a function of time in the form of process data and the process data are processed in at least one first data processing work and output as production data.
- the surface of the product is observed by means of a surface inspection system within or at the end of the production process, the surface being recorded from the observation data in at least one second data processing unit as a type of surface map with identified surface features in the form of surface data, and the surface features after various types and / or classified according to size and / or frequency and entered in the surface map according to their position.
- the different classes and positions of surface features are output as product data.
- the production data and the product data are then jointly supplied to at least one third data processing unit, where they are examined for correlations between them, rules being established as to how the product data depend on specific production data.
- the process parameters can then be set in accordance with the established rules and their interpretation in the form of suitable control signals in order to achieve a desired quality.
- a correlation module is therefore installed in the third data processing unit, which examines the supplied data for significant correlations.
- Various correlation principles come into consideration for such a correlation module. Examples of this are neural methods and statistical methods.
- a program is preferred which is based on the fact that the data to be correlated are represented in a data space in such a way that the entropy reaches a minimum. This results in accumulations of data at certain points in the data room, which indicate correlations and can be formulated in the form of laws or dependencies.
- Such a correlator initially delivers empirically and without any theoretical explanation connections between production parameters and product data, from which setpoint settings for the production parameters can be derived to achieve certain product qualities and adjusted during production.
- the invention makes it possible, for the first time, to correlate complex surface data of the end product with production parameters virtually online, and thus enables laws and relationships to be found which, due to their complexity, could not previously be recognized. Only the preparation of surface data by recognizing and classifying surface defects allows the flood of data when observing the surface by cameras to be brought to a level that allows a sufficiently quick examination for correlations with production parameters.
- the function of the first data processing unit 5 and the second data processing unit 8 is important.
- a preselection of data a so-called aggregation of the data, can be carried out according to criteria which can be specified by the user in order to be recognized as unimportant for the respective task or in general Exclude data.
- certain primary data recognized as important can also be forwarded quickly without any processing so that they are available in the third data processing unit for the analysis of correlations. In particular, once certain correlations have been found, the data that correlate with other data can be forwarded.
- the operation of the entire device results in the analysis of increasing amounts of data and by finding various correlations, a certain number of dependencies, which can be visualized, printed out or saved as rules on the one hand, but which are also automatically fed back to control the production arrangement to maintain a certain quality can.
- a production arrangement 1 in particular a hot rolling mill for producing a product 2, in the present case rolled steel, is present.
- the production steps upstream of the hot rolling mill namely the so-called secondary metallurgical ladle treatment and a casting process in which the contents of a ladle are cast to produce a strip material, cooled and passed through a tunnel furnace.
- All stages of the manufacturing process are equipped with a large number of measuring sensors 3, which transmit measuring values 4 via measuring lines, which according to the state of the art are used in a manufacturing control system for regulating the production arrangement 1 or the upstream production processes.
- these measured values are additionally fed to a first data processing unit, in which a pre-evaluation or selection, a so-called aggregation of the data, is carried out.
- a pre-evaluation or selection a so-called aggregation of the data, is carried out.
- the product 2 after hot rolling and annealing, passes under a surface inspection system 6 before being wound up.
- the surface inspection system 6 consists in particular of a number of cameras distributed over the width of the product 2 with a downstream, networked one! Image analysis system.
- Such a system is described, for example, in the "Automatic Hotstrip Surface Inspection HTS-2W" brochure from Parsytec Computer GmbH, Auf der Huels 183, D-52068 Aachen, Germany.
- these quality data can be added to the manufactured product, for example a roll of rolled steel strip, as a quality certificate.
- the surface data are now fed to a second data processing unit 8, in which the data is aggregated.
- the second data processing unit 8 can also be integrated into the image analysis system 7 of the surface inspection system 6, which is already present.
- the first data processing unit 5 and the second data processing unit 8 are connected to a third data processing unit 11 via a first data line 9 and a second data line 10, respectively.
- a correlation module 12 for correlations between them.
- any known type of correlation search can in principle be used in the correlation module 12.
- data mining tools have proven to be particularly favorable for the case described here.
- Such correlation modules have so far only been used to find correlations between simple product data and the parameters of a production process.
- the present invention provides through an output / display unit 13 certain rules that enable the prediction of certain surface features of the product at certain values for process parameters and thus a targeted process management to achieve a certain surface quality.
- measurement results of the surface inspection system can be fed directly into the production arrangement 1 for regulating process parameters via a feedback 14.
- the invention enables the rapid gathering of knowledge of the manner in which production parameters, in particular in the case of a casting and rolling plant for sheet steel, are related to certain surface properties, as a result of which a more targeted process control for the production of certain qualities and a faster running-in of new plants is made possible.
- the principle described here using the example of a rolling mill can also be used in other production plants for flat strip materials, for example coating plants, paper production facilities, etc., with the same advantages. List of reference symbols
