| Abstract: | To upgrade the automatic control of flatness of strip, a relevant control system was designed and developed for the signal-stand reversing cold mill in Ansteel, with a domestic magnetic-pressure flatness meter used for cold-rolled strip. The structure, operating principle and implementation of the flatness control system were described in detail. In the design of the control system the efficiency factor of flatness was introduced to develop the control model, and efficiency factor of flatness can serve the function of improving the control accuracy of strip shape. With the online flatness control system applied to the detection of the strip as the products from a reversing cold mill, the flatness error is available to be controlled within ±50 μm/m. |
