【摘要】 设备故障分析与管理是企业设备管理的重要部分,保证设备的使用寿命和运行稳定性对钢铁企业的生产运营至关重要。论文首先对某热轧厂工艺流程与设备进行简介,通过简短文字和图片介绍生产线设备的基本性能、参数和结构等。其次对设备故障统计与分析,从故障现象、原因分析、解决办法、故障时间和故障分类等方面对故障进行分析。然后对设备故障管理与经济效益进行研究,通过各种数据、图表、曲线等形式表示重复发生故障潜藏的经济效益。从186项设备故障分析,重复发生故障91次,故障时间93.86h,占全部故障频数48.92%,占全部故障时间54.81%。非重复发生故障95次,故障时间77.38h,占全部故障频数51.08%,占全部故障时间45.19%。根据经济效益的计算公式,重复发生故障损失产量42237吨,按照热轧板带平均价格3400元/吨,重复发生故障损失产量带来经济损失1.4亿元,非重复发生故障损失产量34821吨,非重复发生故障损失产量带来经济损失1.1亿元。论文收集某热轧厂近几年的设备故障,整理、汇总多种判断和分析设备故障的方法。针对重复发生故障,制定一些相关的操作规程,改造设备不合理的地方,减少故障的发生,预防故障的发生,保证设备运行平稳。针对以上故障点,细化《设备维护规程》,制订《重点设备点检签到表》,从制度到执行保证集中人力点检故障点,减少故障发生,减少重复发生故障。更多还原

【Abstract】 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.更多还原
