反应堆内构件下栅格孔板平面加工变形控制

Elimination of Surface Machining-Caused Deformation of Bottom Perforated Plate inside Reactors

介绍反应堆内构件中关键加工件下栅格孔板开孔前后的平面加工易产生较大的变形的特点,以及为克服该加工难点在平面加工过程中所采取的各种控制变形的措施。

The bottom perforated plate, a critical internal component of reactors, is prone to deform as the result of machining on the surfaces before and after hole drilling. Some measures have been taken to overcome the machining difficulties and eliminate the deformation during machining process.
