【摘要】：故障树分析，是一种图形化的分析方法，它是利用图形和一定的逻辑关系，对设备、系统等进行故障的分析和诊断，它应用的范围很广泛，，主要有安全性分析和故障诊断。而随着软件技术的不断发展，故障树分析的方法，进一步得到了改进和提高，并且逐渐形成了完整的理论和程序，而得到了很大的发展。本文主要利用先进的故障树理论，针对莱芜钢铁集团银山型钢有限公司板带厂1500mm宽带精轧机组经常出现的主要故障进行了理论分析，把各种故障的因果关系表现出来，有利于对机械设备故障的综合分析，更加具体化、系统化，更加直观的了解了精轧机组设备的在线运行状态。本文主要阐述了故障诊断技术的发展趋势、故障诊断技术的定义、故障诊断方法、故障树方法的特点，了解了故障树方法常用的基本符号。利用故障树理论，对宽带精轧机组的设备组成、技术性能与基本参数、结构及工作原理进行了系统的分析，主要针对机械液压电气经常出现的问题，分子框架组件的故障分析，故障分析工作辊，支撑辊组件故障分析，压下装置的失效分析，弯辊移动装置故障分析，移动垫装置平衡装置的故障分析，传动装置电气系统的故障分析，液压系统的故障分析，分别画了故障树分析图，直观明了。掌握了故障树理论，使之成为程序化，能更好的分析现场故障，能以最快的速度，用排除的方法确定真正的故障产生原因，提高了工作效率。实践表明，该理论系统工作稳定可靠、直观性强、监测准确度高。
[Abstract]:Fault tree analysis is a graphical analysis method, it is the equipment using graphics and the logical relationship between the fault analysis and diagnosis system, the scope of its application is very extensive, mainly in security analysis and fault diagnosis. With the continuous development of software technology, the fault tree analysis method further, an improved and enhanced, and gradually formed a complete theory and procedure, and obtained great development.
This paper mainly uses the advanced fault tree theory, the main faults in Laiwu iron and Steel Group Steel Co. Ltd. in Yinshan belt factory 1500mm broadband mill often analyzed, show the faults of causality, is conducive to a comprehensive analysis of the mechanical equipment fault, more specific, systematic, more intuitive to understand the online running state of rolling mill equipment.
This paper mainly expounds the developing trend of fault diagnosis technology, the definition of fault diagnosis, fault diagnosis method, the characteristics of the fault tree method, fault tree method to understand basic symbols commonly used. By using the fault tree theory of broadband mill equipment, technical performance and basic parameters, structure and working principle of the system the analysis, mainly for mechanical hydraulic electrical problems often occur, fault analysis of molecular framework components, fault analysis and fault analysis of supporting roller assembly, pressing device failure analysis, fault analysis and fault analysis of mobile mobile device corner pad device balancing device, electrical transmission system fault analysis, fault analysis the hydraulic system, the paintings were of the fault tree analysis, intuitive and clear.
The fault tree theory, making procedure, field failure analysis can better, to the fastest speed, by removing the method to determine the real cause of the malfunction, and improve work efficiency. It is shown that the theoretical system is stable and reliable, intuitive, measurement accuracy is high.
