Abstract：In order to increase the measuring precision of cold strip shape, a new cold strip shaper——the entire roller inlayed block intelligence shape meter was developed. The structural form which was different from the international popular segmented detection roller was put forward and the entire detection roller inlayed block was 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 was different form the international popular dry slip ring was put forward, and the spray wet slip ring was developed to improve the measuring precision and the service life. The signal processing form which was different form the international popular gathering card was put forward and the embedded DSP shape signal processing hardware system was developed to improve the measuring precision and the anti-interference ability. The shape signal processing software system whose function contained error compensation, pattern recognition, establishment of the target shape and the closed-loop control calculation was built to implement the intelligentized shape meter. The shape meter was tested chronically on the 1250mm cold strip mill of Angang Steel Company Limited and the result show that the measuring signal is stable and reliable and the closed-loop control of shape is implemented.
