Research Of A Hot Rolling Mill Equipment Failure Analysis And Management

Equipment failure analysis and management is an important part of the enterprise device management,service life and operation of the equipment is crucial to the stability of the production of iron and steel enterprises operating guarantee.Firstly,on a hot rolling mill process and device profiles,describes the basic performance parameters and structure of the production line equipment,such as through short text and images.Secondly,equipment failure statistics and analysis,from the failure phenomenon,cause analysis,solution,time to failure and fault classification and other aspects of failure analysis.Then the device fault management and economic research,through various forms of data,charts,graphs and other potential economic benefits,said the fault occurs repeatedly.From the 186 equipment failure analysis,repeated failure 91 times,the failure time of 93.86h,accounting for 48.92%of all the frequency of failure,accounting for 54.81%of all the failure time.Non repeated failure occurred 95 times,the failure time 77.38h,accounting for 51.08%of all the frequency of failure,accounting for 45.19%of all the failure time.According to the formula for calculating the economic benefit and repeated fault yield loss 42237 tons,according to the hot rolled plate with the average price of 3400 yuan/ton and repeated failure of yield loss caused economic loss of 1.4 billion yuan,non recurring fault yield loss 34821 tons non recurring fault yield loss bring economic loss of 1.1 billion yuan.Papers collected in a hot rolling mill equipment failure in recent years,sorting,summary judgment and to analyze a variety of equipment failure.For local repeated failure to enact some relevant rules,transformation equipment unreasonable to reduce the incidence of failure to prevent the occurrence of faults,to ensure the smooth operation of the device.In view of the above fault,refining the equipment maintenance procedures",making the key equipment inspection registration form",from system to execute ensure centralized human inspection point of failure,reduce the occurrence of fault,reduce repeated failure occurs.Loss of production loss to bring economic loss of.
