液压弯辊控制参数对热连轧机振动能量影响研究

Effect of hydraulic bending roll on vibration energy of a hot continuous rolling mill

近年来,热连轧机振动问题显得更加突出和复杂化,众多企业迫切需要解决这一难题。首先对某热连轧机振动现象进行在线监测;然后依据轧机实际参数建立液压弯辊系统和轧机垂直系统的耦合动力学模型,利用MATLAB进行了仿真研究,通过改变液压弯辊系统中控制器参数,获得液压弯辊的控制性能对辊系振动能量的影响,实践表明这是有效抑制振动的措施之一。

In recent years,hot continuous rolling mill vibration problems are more prominent,many enterprises urgently need to solve this problem.Here,the vibration problem of a hot continuous rolling mill was monitored online.Then,a coupled dynamic model of a rolling mill vertical system and a hydraulic bending roll system was built.According to the actual mill parameters.MATLAB was used to do a simulation study.The effects of the control performance of the hydraulic bending rolls system on the rollers system vibration energy were analyzed by changing the controller parameters of the hydraulic bending roll system.The results provided one of effective measures for suppressing vibrations of hot continuous rolling mills.
