摘要
通过对马头发电厂 # 8机组锅炉汽包分散降水管缺陷处理过程中的残余应力分析 ,以及对处理后的角焊缝残余应力实际测量 ,证明汽包分散降水管的缺陷处理可以不进行规程要求的 6 0 0℃以上的热处理。
Through the residual stress analysis of No.8 boiler in Matou Power Plant after repair welding of the distributed downcomers and the measured values of residual stress of fillet welds after treatment, the heat treatment over 600 ℃ for the repair fillet welds of distributed downcomers asked by the codes is proven can be omitted.
