摘要
对压水堆堆内构件的围板的结构特点和功能进行了简述,介绍围板的机械加工工艺特点,包括铣削和刨削加工工艺的特点、奥氏体不锈钢加工难点、影响机加工质量的因素、机械加工残余应力产生的原因及其对产品的影响等。围板通过适宜的工艺优化方案提高其产品机加工质量和合格率,使产品达到其设计要求和满足其用途。
The structure characteristics and functions of baffles in the reactor internals in PWR were briefly intro- duced. The mechanical processing characteristic of baffle were described, which includes technique characters of milling and planing, processing difficulties of austenitic stainless steels, factors effecting the quality of mechanical processing, causes of residual stress produced in mechanical processing and their effects on products, etc. A preferable process was ob- tained through process optimization which increased the processing quality and pass rate of product and made the products meet the design and engineering requirements.
