Abstract: A semi-automatic adjustment device for suppressing tension fluctuations during a rolling process of an ultra-thin strip includes a semi-automatic tension regulator, a semi-automatic tuned mass damper of variable stiffness and damping, a coiler, a tension roller and a twenty-high roller system. The semi-automatic tension regulator is disposed between the coiler and the tension roller, the semi-automatic tuned mass damper of variable stiffness and damping is disposed between the tension roller and the twenty-high roller system. The semi-automatic adjustment device can be used to reduce a short-time fluctuation impact of tension during startup and shutdown of a twenty-high roll mill when the twenty-high rolling mill rolls an ultra-thin strip, improve system stability, absorb the continuous micro disturbances generated during the rolling process of the twenty-high roll mill, and achieve flexible and stable adjustment of tension during the rolling process.
