    Abstract: A single-side tower-type roller system based asynchronous rolling mill for rolling an ultra-thin composite strip and a hydraulic system therefor are provided. The mill includes a machine frame and reel assemblies. An upper roller system assembly and a lower roller system assembly are arranged in the machine frame. A down-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the upper roller system assembly and the lower roller system assembly. A support roller balance assembly is arranged on the machine frame and used to support and balance the upper roller system assembly. The lower roller system assembly includes right and left working rollers. The right working roller is a plain roller. The left working roller is a patterned roller. A left-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the right and left working rollers.

    Abstract: A vibration suppression method and system of a rolling mill roller assembly based on a vibration damping device are provided. The vibration suppression method includes: obtaining a first amplitude-frequency relationship during a vibration process of a rolling mill roller assembly vibration suppression system; based on the first amplitude-frequency relationship, determining two time domain relationships and two second amplitude-frequency relationships by a simulation analysis; based on the two time domain relationships and two second amplitude-frequency relationships, adjusting parameters of the vibration damping device until a vibration displacement of the rolling mill roller assembly vibration suppression system is less than or equal to a vibration displacement threshold. And provides a new solution for the stability control of the rolling mill, and ensures the reliability and stability of the vibration suppression of the rolling mill.

    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.
