中文摘要：目前国际上普遍采用锻件制造反应堆压力容器，反应堆压力容器锻件的热加工的质量控制直接关系到反应堆压力容器部件的质量，反应堆压力容器部件制造质量是能否满足设计质量的关键。以某百万千瓦级核电站反应堆压力容器顶盖法兰锻件的生产为例，针对锻件的特点，控制生产中重要工序的质量影响因素,过程控制中应注意的问题和避免出现质量问题的关键。分析如何通过对热加工质量的过程控制，得到满足设计要求的合格产品。主要涉及到炼钢、锻造、热处理等工序过程控制的实施。
英文摘要：At present, the manufacture of reactor pressure vessel is mainly forging process in the world. The quality control of forging hot-working process is directly related to the quality of reactor pressure vessel components, and is the key points of whether the manufacturing quality can meet the design requirements or not.According to the production example of cover flange forging used for one of mega-kilowatt nuclear power station reactor pressure vessel, focusing on the features of reactor pressure vessel forging, the influence factors control of important procedure in production quality is important. The problems in the process control and how to avoid these problems should be paid attention to. How to manufacture products to satisfy the design requirements through the quality controlling of hot-working process involves the process control of steel-making, forging, heat treatment, etc.
