总结归纳了轧钢机的主要故障,针对轧钢机的结构和故障特点,将轧钢机的故障划分为设备故障、系统故障和产品质量故障3个级别,并分析了轧钢过程变量的数据特点以及轧钢机的故障特性。综述了轧钢机故障诊断方法,从整体上将轧钢机的故障诊断方法分为定性分析和定量分析两大类,并详细介绍了每种轧钢机故障诊断方法的基本思想、发展现状,重点介绍了多元统计的方法。指出了轧钢机故障诊断研究存在的问题和未来发展的方向。
Summarizes the main faults of the rolling mill, according to the structure and fault characteristics of the rolling mill, the fault of the rolling mill is divided into three levels: equipment fault, system fault and product quality fault. The data characteristics of the rolling process variable and the characteristics of the rolling mill Fault characteristics. The fault diagnosis methods of rolling mills are reviewed. The fault diagnosis methods of rolling mills are divided into two categories: qualitative analysis and quantitative analysis. The basic ideas and development status of each rolling mill fault diagnosis method are introduced in detail. Multivariate statistical methods. The problems existing in the fault diagnosis of rolling mills and the direction of their future development are pointed out.
