【摘要】 在核电设备制造过程中对质量的控制是头等大事。AP1000核电主设备安注箱的制造中，主环缝的对接是关键工序，其错边量超差是制造的瓶颈之一。为控制环缝间的间隙，保证安注箱的生产，对关键工序进行质量控制对于安注箱的制造质量和周期都具有重要意义。本文对辅机厂（SAP）核电安注箱的整体制造过程进行分析和研究，以工序质量控制为中心，分析了安注箱工序过程管理、工序过程控制和产品质量现状。针对工序过程管理和工序过程控制，给出了安注箱关键工序的质量控制方法：运用质量控制工具排列图统计并分析出主要产品质量问题——环缝的错边量超差问题。运用鱼刺图对安注箱关键工序过程的各工序生产要素（5M1E）进行分析，找出在人、机、料、法、环、测上导致环缝错边量超差的主要原因。运用质量管理工具（控制图）对关键工序过程进行质量管控，优化各工序生产要素的控制条件，设置关键工序控制点，改善环缝错边量超差质量问题。运用PDCA循环理论，针对工序过程管理中工序流程不规范，设计出规范化的工序流程。最后，通过后续安注箱做验证，对本文提出的方法进行分析，结果表明：改善了安注箱对接环缝的错边量超差，提高了设备的质量，解决了生产瓶颈，使制造周期大大缩短。更多还原

【Abstract】 Quality control is the top priority in the nuclear power equipment manufacturingprocess. In the manufacture process of AP1000nuclear power main equipmentaccumulator tank, the butt joint main ring seam is a key process, the unfitness of butt jointout-of-tolerance is one of the bottlenecks in manufacturing. In order to control the ring gap,guarantee the accumulator tank production, has important significance in quality controlof manufacturing quality and cycle for the accumulator tank of key working procedure.The paper is to analyse and research on the accumulator tank manufacturing processof Shanghai power station auxiliary equipment plant (SAP), keeping the process qualitycontrol as the center, analysis of the accumulator tank working procedure processmanagement, processing control and product quality in the process. Focusing on workingprocedure process management and process control, providing ways on quality control tothe key process of accumulator tank:Using the tool of quality control Pareto diagram static and analyse that the mainproblems in the quality of products is the unfitness of butt joint out-of-tolerance.Using the fishbone chart to analyse each process of production factor (5M1E) ofthe key working procedure on the accumulator tank, finding out in human, machine,material, method, measurement and environment, main causes of the unfitness ofbutt joint out-of-tolerance.Using of statistical techniques (control chart) to manage and control the keyworking procedures, optimizing the production factor control conditions of eachworking procedure, and setting the control points, to improve the quality of theunfitness of butt joint out-of-tolerance.Using PDCAcirculation theory, designing the standardized procedure processes forprocedure process management processes that are not standardized. Finally, through the subsequent accumulator tank as certification, analyses themethod referred in the paper, resulting that: improved the unfitness of butt jointout-of-tolerance of accumulator tank, improved the quality of the equipment, solvedproduction bottlenecks, which greatly shorten the manufacturing cycle.更多还原
