中文摘要：目前国际上普遍采用铸件制造冷却剂泵泵壳，冷却剂泵泵壳铸件的铸造质量控制直接关系到冷却剂泵的质量，同时也是冷却剂泵制造质量能否满足设计质量的关键。以某百万千瓦级核电站冷却剂泵（简称主泵）铸件的生产为例，针对大型铸件的特点，分析如何通过对热加工的过程控制，得到满足设计要求的合格产品。
英文摘要：At present, the manufacture of reactor coolant pump casing is mainly casting in the world. The quality control of reactor coolant pump casing casting is directly related to the quality of reactor coolant pump and is the key points whether the manufacturing quality can meet the design requirements or not. Taking mega-kilowatt nuclear power station reactor coolant pump casing as an example, aiming at the features of casing, how to manufacture products to satisfy the design requirements through the control of hot-working process is analyzed.
