DEVELOPMENT OF PROFILE FORGING FOR CHANNEL HEAD OF AP/ACP STEAM GENERATOR

摘要：

　　The AP/CAP Steam Generator has the most complex structure in current nuclear power plant forgings.In order to improve material utilization and nozzle Properties,China First Heavy Industries(CFHI)have carried out the study on profile and blocker-type forging for Channel Head.The numerical and physical Simulations verify that the channel head can be forged step by step in profiling dies with 100~150MN hydraulic press.The achievement has been applied firstly in the AP1000 project of Xian Ning 1#.On this basis,the optimizations of forging process and die structure have been completed.Through process optimizations above,the nozzles of different shapes have obtained uniform deformation and the full-size channel head forging(Including main forging and samples)of CAP1400 steam generator has been manufactured successfully.And the mechanical properties indicate that the toughness has been improved obviously and the gas content has been reduced effectively in nozzle regions.
