研究了热壁加氢设备用焊条的特征、熔敷金属的韧性、抗回火脆性及影响回火脆性的因素。通过严格筛选原材料，控制熔敷金属中的杂质含量，采用优化设计的先进手段设计出了Ｒ４０７Ａ热壁加氢设备的专用焊条，对Ｒ４０７Ａ焊条进行了回火脆性试验和脆性转变温度等试验，焊条的各种性能完全达到了日本ＣＭＡ－１０６Ｎ焊条的水平，可以取代同类进口焊条

The characteristics of electrode for hot wall hydrogenation equipment, the toughness of deposited metal, the anti-temper embrittlement and the factors affecting the temper embrittlement were studied. By strictly screening the raw materials and controlling the content of impurities in the deposited metal, a special welding rod for R407A hot-wall hydrogenation equipment was designed by the advanced means of optimum design. The R407A electrode was tested for temper embrittlement and brittle transition temperature. The performance of all kinds of CMA-106N electrode fully meet the level of Japan, can replace similar imported electrodes
