Abstract
The invention relates to a flatness measurement and control system for metal strip, which makes it possible to obtain improved strip or coil quality by a simple and effective measurement of departures from flatness and to control the finishing parameters through the evaluation of a line pattern on the strip surface or on the end face of a coil as it is coiled.
Claims2
A rolling mill train comprising:
- a finishing stand;
- a strip cooling line;
- a coiler;
- first measuring means comprising a first CCD camera and a first projector, the first measuring means located before the strip cooling line;
- and
- second measuring means comprising a second CCD camera and a second projector, the second measuring means located after the strip cooling line, the first and second measuring means being configured to measure strip flatness;
- wherein the first and second measuring means are coupled with means for controlling the finishing stand, the strip cooling line and the coiler.
