【摘要】 本文针对反应堆主设备制造监造难点,论述专业化监造体系的构建和实施效果。专业化监造的内涵一是要配置学科合理的监造工程师团队和技术支持专家团队,二是要建立监造体系,确保在关键设备制造过程中实施"质量第一"的监造管理制度。监造要着重对质量保证实施难度大的属于承压边界的压力容器等设备编制监造计划,实施重点监造。专业化监造的实施,确保了关键设备制造过程受控,监造控制有力,不符合项全部按程序处理,主设备制造质量缺陷可以追溯。通过对观察意见单和备忘录的分析:制造过程中"人、机、料、法、环、测"各控制因素,人的因素占比为89%,法的因素为12.5%。NCR分析表明:NCR数量集中产生在关键设备集中制造的时期,制造阶段占比为92.3%;一类NCR占比68.9%,二类NCR占0.6%,内部NCR占30.5%,没有三类NCR;"人因、程序、设备、材料、采购、设计、其他"影响因素中,材料为69.1%人因为21.2%。专业化监造体系的构建和实施,有力的促进制造厂改进制造质量,避免产生三类重大不符合项,少报废产品,促进效益提升。有效的协调了"质量第一"和"进度刚性"的矛盾。更多还原

【Abstract】 This paper discusses the construction and implementation effect of specialized supervision system for settling the difficulties of and monitoring of the key equipment manufacturing of the first reactor.The connotation of professional supervision is to set up a reasonable discipline supervision engineer and technical support team of experts,and a hierarchical supervision system,ensures the implementation of "quality first" management system in the process of key equipment manufacturing.And monitoring plan must be prepared for such as the pressure vessel,which is primary monitoring equipment with high quality assurance of Pressure boundary.Particularly,in the process of the manufacture of pressure vessel,it is necessary to focus on such as non plastic transition temperature test,to strict control the personnel of implementation process,to follow up the manufacturing cycle closely,and reporting to the owner to take measures to coordinate the manufacturing progress. The implementation of specialized supervision,ensures that the quality plan is a comprehensive review,and raw materials in the manufacture of key equipment is to meet the requirements of technical specification for procurement.Through the analysis of the observations and the memo,the manufacturing process of human,machine,material,method,ring,measurement of the various factors,the proportion of people accounted for 85%,accounting for the proportion of procedures for the 12.5%.The supervision engineer must control the nonconformity,to ensure that the equipment manufacturing quality can be traced;the Monitoring engineer must analyzes the quality trend,to ensure that the owners in time to grasp the major manufacturing difficulties;Monitoring Engineer must analyzes the phase and cause of nonconformity,timely feedback to the owners,the owners urge the manufacturers to improve the quality of manufacturing,so that to avoid the three major categories nonconformity,less scrap products,and promote the improvement of efficiency.The quality trend analysis shows that the nonconformity concentration is generated during the process of key equipment manufacturing,the highest proportion of nonconformity in the manufacturing stage was 92.3%;the ratio of first class nonconformity is 68.9%,the ratio of Second types nonconformity is 0.6%,the ratio of internal nonconformity is 30.5%;Human factors and materials are the main factors leading to the nonconformity,the material is 69.1%,because human factors is 21.2%;The components and the implementation of the specialized supervision system effectively coordinate the contradiction between "quality first" and "progress rigidity".更多还原
