Shape Detecting and Shape Control of Cold Rolling

Based on the shape detecting principle and the DSP (Digital Signal Processing) technology, a high-precision shape detecting system of cold rolling strip is developed to meet industrial application. It was successfully used in Angang 1250 mm HC 6-high reversible cold rolling mill. The precision of shape detecting was 0.2 I, the shape deviation was controlled within 6 I after the close loop ...
