基于生产运行数据的RH真空精炼装置可靠性分析
|
摘要
流程工业的生产运行数据虽然海量,但一般不直接反映设备的运行状况,需要设计针对性的方法获取可靠性数据。由炼钢车间的RH真空精炼炉连续生产记录数据和实际工艺流程,分离出故障数据,拟合出故障间隔时间分布模型,并进行参数估计和假设检验,确定现有RH运行的可靠性评价指标,并从可靠性角度分析RH顶枪对真空精炼装置的核心功能部件真空槽的影响。研究结果表明:在相同的生产环境下,SCAP顶枪和KTB顶枪对RH真空槽设备的运行可靠性影响相当,SCAP顶枪好于KTB顶枪。
Although the productive process data of the process industry is massive,it does not directly reflect the operation status of the equipment. It is necessary to take effective method to obtain the reliability data.From steelmaking workshop's RH vacuum refining furnace continuous produced data and the actual process,we acquired the failure data and fitted out the distribution function of the equipment's Mean Time Between Failure and performed parameter estimation and hypothesis testing and finally determined the reliability evaluation index of RH furnace. The study focused on the influence of RH top lance on vacuum refining furnace core function component vacuum vessel from the perspective of reliability analysis. The result shows that,the SCAP top lances and the KTB top lances have a considerable impact on the operational reliability of RH vacuum vessel at the same production environment. The SCAP top lance is better than the KTB top lance.
