Research And Application Of Pickling Efficient Coiling Fault Tree In The Fault Diagnosis Of Broadband In Rolling Mill

Fault tree analysis is analyzed, a graphical method, it is the use of graphicaland logical relationship, analyzing and diagnosing fault of equipment, systems, thescope of its application is very extensive, mainly in security analysis and faultdiagnosis. But with the development of software technology, the method of fault treeanalysis, further improvement, and gradually formed a complete theory and program,and obtained the very big development.This paper mainly uses the advanced fault tree theory, the main faults in LaiwuIron&Steel Group Co. Ltd. in Yinshan steel belt factory1500mm broadband mill areanalyzed, show various fault causality, is conducive to a comprehensive analysis ofthe mechanical equipment failure, more specific, systematic, more intuitiveunderstand the online running state of mill equipment.This paper mainly describes the development trend of fault diagnosis technology,the fault diagnosis technology, the definition of fault diagnosis method, fault treemethod, the understanding of the basic symbols commonly used fault tree method. Byusing the fault tree theory, the broadband mill equipment composition, technicalperformance and basic parameters, structure and working principle for the analysisof the system, mainly for the mechanical hydraulic electrical often appear problem,divided the frame assembly fault analysis, fault analysis of work roll assembly,supporting roller assembly fault analysis, fault analysis, bending and pressingdevice roll shifting device of fault analysis, fault analysis, balance device formobile pad device of fault analysis, fault analysis, transmission device electricalsystem fault analysis, electro hydraulic system fault analysis, fault tree analysisdiagram are painted, intuitive and clear.Master fault tree theory, make it become the program, field failure analysis canbe better, can with the fastest speed, with the exclusion of the method to determinethe real fault causes, improve work efficiency. Practice shows that, the theory systemis stable and reliable in work, strong visualizability, high monitoring accuracy.
