文摘The single stand mill requires constant tension value during the rolling of the same pass, however, with the change of the coil diameter during rolling, the motor torque of the tension reel will also change, so the calculation accuracy of the coil diameter has become an important parameter that affects the stability control of tension. The paper introduces two methods that can be used to calculate the coil diameter of a single frame, and analyzes their advantages and disadvantages respectively. Finally, the angular velocity counting method to be used and the compensation method is adopted to ensure the accuracy of the calculation.
