Definitions
- the invention relates to a method for tape edge detection in a cold rolling mill and / or belt system, in which by means of two optical detection systems contactless, the band edges are continuously recorded.
- a method for controlling the strip running during rolling, in particular finish rolling of self-luminous hot strip in one of several rolling mills arranged successively rolling train in dependence on the position of the two band edges comprises the combination of the following features:
- a contactless, optical measuring device is arranged in the direction of passage of the strip behind at least one rolling mill Band edge outgoing line simultaneously recorded both band edges.
- the distances between the strip edges are determined by a reference point corresponding to the middle of the rolling train.
- an actuating signal for an adjusting device for adjusting the nip of the roll stand is formed.
- the strip run is corrected by adjusting the nip of the rolling mill immediately upstream of the measuring device in the direction of the strip.
- a measuring device a line scan camera is used.
- JP 6 147 856 a device is known, in which the strip edges of a rolling stock are recorded without contact by means of two cameras and conclusions are drawn by evaluation in a processor on the strip center profile.
- the detection of the band edges by two cameras is also known from JP 63 225 107.
- the unevenness of the surface of a rolling stock is determined in JP 80 54217 A2 by the use of multiple cameras.
- the invention has the object to improve the detection of the tape position and to automatically correct the tape position.
- This object is achieved in a method for tape edge detection in a cold rolling mill and / or belt system in which by means of two optical detection systems contactless tape edges are continuously resolved in that the right edge band and the left band edge over a band length of more than 800 mm by means of a Captured imaging device, the image data edited in a computer and the thus determined band edge profile is taken into account in the scheme. Further embodiments of the method will become apparent from the dependent claims.
- the image pickup device in a first embodiment is a digital camera, i. a known and proven device is used.
- an optical detection system In order to detect the strip during threading into the closed roll gap in cold rolling mills, an optical detection system is used.
- the recognition system offers on the one hand the advantage of non-contact measurement and on the other hand an easy extensibility without major hardware changes.
- Continuous image acquisition by means of two optical detection systems, each of which detects a band edge, permits continuous recording of the band profile in the monitored area (quality assurance).
- the band edges are determined in their angular position as well as their position.
- the information about the band position is used in a regulation for actively changing the inclination. About the change of the tilt, in turn, the band position is set.
- the entire calculation of the band position as well as the generation of the controlled variables take place on a computer outside the actual rolling plant and / or the belt system. Due to the small dimensions of the optical detection systems used eliminates a costly conversion of the rolling mill and / or the belt system.
- the optical detection system can also be installed in critical environmental conditions such as lubricant mist within a rolling mill / belt plant. The installation takes place in a protected position; the distance to the band can be chosen freely. Only indirect lighting is required.
- band edge tears can be metrologically recorded and evaluated.
- the advantage is that consequential damage can be reduced by tape breaks.
- coarse band surface defects such as e.g. Markings on the work roll, which are reflected on the strip surface, are detected and detected accordingly.
- optical recognition systems are suitable for all bandwidths of the rolling mill / conveyor system due to their fixed installation.
- FIG. 1 is a plan view of an inventive detection system
- Fig. 3 in plan view the detection system at a special
- the detection system 1 is shown in principle.
- the rolled strip 3 emerging or entering from the roll gap 2 is detected by two cameras 4, 5 arranged above or below it.
- the viewing area 6, 7 of the cameras 4, 5 includes, for example, an area that does not take into account the center of the strip 8.
- the band center can also be taken into account via installation of additional cameras.
- the digital video signals 9, 10 obtained by the cameras 4, 5 are read into a computer 11.
- Evaluation software determines a plurality of edge points 12 of the strip edges 13, 14. The position of the edge points 12 and their course (see FIG. 2) are evaluated in the computer 11. If differences are found in relation to a given edge profile, a change in the roll gap setting is effected, for example, by a signal for pivoting the roll.
- the control can address the upstream and / or downstream roll stand.
- FIG. 2 shows in simplified form the differences between a band edge detection with only one edge point 12 (left column) according to the prior art and the band edge detection according to the invention with a plurality of edge points 12 (right column). While the distance and the position of these two edge points 12 can be determined / determined with only one edge point 12, no statement can be made about the course of the rolled strip 3. Different with a band edge detection with several edge points 12. By the twelve edge points 12 on the right band edge 14 and on the left band edge 13 shown in the example, it can be determined whether the rolled strip 3 runs in the middle (a), pivoted to the left (b), forms an arc (c) or wavy (d).
