摘要
EPR压力容器中接管段部件采用新的设计方案,将容器法兰与接管段合二为一,同时将进出口接管的部分作为一个整体环一体锻造在接管段壳体上。通过对冶炼、铸锭工艺、锻造工艺以及热处理工艺的研究,同时对现有设备及辅具进行必要改造,使制造过程保证了锻件具备良好的强度、塑性和低温韧性等综合指标。
The nozzle shell of EPR w：ssels adopts a new design, that is to forge the vessel flange and the nozzle shell together as monblock , and in further, the sockets of inlet and outlet nozzles are forged as rings integrated in the nozzle shell. CFHI （China First Heavy Industries） establishes proper steel melting, ingot casting, forging and heat treatment procedures and modifies the related equipment and auxiliary tooling to make the torgings with the strength, plasticity,low-lemperature toughness and other mechanieal properlies that meet the requirement.
