摘　　要：控制棒星形架是控制棒组件的关键部件,采用多个零件组装而成,其中最重要的组装工艺是钎焊。由于控制棒星形架需要吊起24根总重量约1 600 kg的控制棒,故其组装钎焊工艺的质量显得尤为重要。本文从控制棒星形架的镍基合金钎料、组装点焊、钎料涂抹到钎焊热处理,完整地介绍了一种可用于控制棒星形架的真空钎焊工艺,为后续不同类型的控制棒星形架钎焊提供理论依据。The RCCA spider is a key part to the RCCA, assembled with multiple parts, and brazing is one of the most important assembling process. As 24 control rods with a total weight of about 1600 kg need to be lifted from the RCCA, the quality of brazing process is particularly important. In this paper, a complete vacuum brazing technology is introduced, including nickel-based alloy filler of brazing, assembling spot welding, filler loading and brazing heat treatment, aiming to offer theory basis for different types of RCCA spider brazing.
