主要研究连轧机振动耦合。通过对轧机振动产生的原因分析,建立了一种轧制过程模型和轧机结构模型耦合的单机架颤振系统,并构建了连轧振动系统。对两个模型进行仿真,比较分析得出引起轧机振动耦合的主要原因是轧辊的振动导致出口板带缺陷和机架间张力的变化,通过现场轧制实验验证了模型和仿真结果的正确性。此外,轧制速度及合理布置轧机间的距离对整个连轧系统的稳定性有着重要的影响。
The main research of rolling mill vibration coupling. Based on the analysis of the causes of the rolling mill vibration, a single-frame flutter system coupled with the rolling process model and the structural model of the rolling mill was established, and a rolling vibration system was constructed. The two models are simulated. The main reason of the vibration coupling of the rolling mill is analyzed and compared. The vibration of the roller leads to the change of the strip flaws and the tension between the stands. The correctness of the model and the simulation results are verified by field rolling experiments. In addition, the rolling speed and the reasonable arrangement of the distance between the rolling mill on the stability of the system has a significant impact.
