摘要
介绍了第三代核电锻造主管道弯曲成形采用的冷模压弯管工艺、热模压弯管工艺和中频弯管工艺,对三种工艺方法的优缺点和对应的弯曲半径特点进行了分析,对目前核电主管道弯曲半径采用的测量方法进行了介绍和评价,为第三代核电锻造主管道的设计、检测和使用提供参考。
This paper introduces the cold die bending process,the hot die press bending process and the intermediate frequency bending process used in the third-generation nuclear power forging main pipeline bending forming.The advantages and disadvantages of the three process methods and the corresponding characteristics of the bending radius have been analyzed,and the current measurement methods adopted for the bending radius of the nuclear power main pipeline has been introduced and evaluated,which provides a reference for the design,inspection and use of the third-generation nuclear power forged main pipeline.
