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.
Claims7
Method for measuring the flatness of metal strip or of the end face of the coil when coiling strip, wherein
- a line pattern (2) is produced on the measurement surface (4) by means of a projector and
- is detected directly by a camera (5)
Rolling mill train comprising a finishing stand (6), a strip cooling line (8), a coiler (7) and measuring means located before and after the strip cooling line for measuring the strip flatness, which is coupled with the means for controlling the finishing stand (6), the strip cooling line (8) and the coiler (7).
