THE ANATOMY OF AP1000 MONO-BLOCK LOW PRESSURE ROTOR FORGING

摘要：

　　AP1000 mono-block low pressure(LP)rotor forgings for nuclear power station have maximum ingot weight,maximum diameter and the highest technical requirements.It confronts many technical problems during manufacturing process such as composition segregation and control of inclusion in the large ingot,core compaction during forging,control of grain size and mechanical performance.The rotor forging were anatomized to evaluate the manufacturing level of CFHI.This article introduces the anatomical results of this forging.The contents include chemical composition,mechanical properties,inclusions and grain size and other aspects from the full-length and full cross-section of this forging.The fluctuation of mechanical properties,uniformity of microstructure and purity of chemical composition were emphasized.The results show that the overall performance of this rotor forging is particularly satisfying.
