We study the problem of operation of sheet rolling mills under the conditions of nonstationary technology, the stochasticity of the parameters in the presence of negative self-oscillation vibration processes associated with the “chatter” phenomenon. We determine the parameters of stability of the process of sheet rolling, reveal the main causes of the chatter phenomenon, and describe the mechanism of their initiation. We also propose a procedure for the identification of this phenomenon by continuous statistical processing of the parameters of rolling process. As a result of the performed investigations, we developed a method aimed at the adjustment of the technology, which excludes vibration and enables us to enhance the productivity of rolling mills by means of increasing the average speed of rolling.

带钢冷轧连续轧机自振荡的研究和工艺稳定程序的开发

我们研究了在非平稳技术条件下薄板轧机的运行问题，在存在与“颤振”现象相关的负自振荡振动过程中参数的随机性。我们确定了薄板轧制过程的稳定性参数，揭示了颤振现象的主要原因，并描述了它们的发生机制。我们还提出了一种通过对轧制过程参数进行连续统计处理来识别这种现象的程序。作为研究的结果，我们开发了一种旨在调整技术的方法，该方法可以排除振动，并使我们能够通过提高轧制平均速度来提高轧机的生产率。
