Research on New Shape Meter of Cold Rolling Strip

Abstract:

Article Preview

A new strip shaper is developed to avoid the scratch of the strip surface due to different thermal expansion of the traditional detection roller measuring unit effectively. The signal transmission form which is different form the international popular dry slip ring is put forward; the spray wet slip ring is developed to improve the measuring precision and the service life. The signal processing form which is different form the international popular gathering card is put forward and the embedded DSP shape signal processing hardware system is developed to improve the measuring precision and the anti-interference ability. The shape signal processing software system whose function contains error compensation, pattern recognition, establishment of the target shape and the close-loop control calculation is built to implement the intelligentized shape meter. The shape meter has been test chronically on the 1250 mm cold strip mill of Angang Steel Company Limited and the test result indicates that the measuring signal is stable and reliable and the closed-loop control of shape is implemented.
