摘　　要：对煤油脱硫加氢热壁反应器在使用了近 2 0年之后的性能进行了试验研究。用相同的材料采用模拟的方法对设备的常温、高温、氢脆、步冷回火脆性及其综合影响进行了分析 ,结果表明 :设备焊缝与母材相比综合性能明显下降 ;1 2 5Cr 0 5Mo基体材料对氢脆、一次步冷回火脆性都不是很敏感 ;并计算出1 2 5Cr 0 5Mo材料在一次步冷脆化的条件下 ,临界裂纹长度为 3 0mm时设备最低升压温度为 -2 0℃。The experimental study on the performance of kerosene desulurization hydrogenated hot wall reactor,after has been operated about twenty years,was put into effect.By the use of the same material and modelling method,the performances of ordinary temperature,high temperature,hydrogen brittleness,step cooling temper brittleness and its comprehensive effect on equipment were analized.The results showed that:The comprehensive performace of weld seam was droped obviously by comparison with base metal;The hydrogen brittleness,first step cooling temper brittle of 1 25Cr 0 5Mo base metal were not sensitive;By calculation,the minimum temperature of boosting pressure for 1 25Cr 0 5Mo steel was 20℃,under the conditions of first step cooling embrittlement and the critical fissure length 30mm.
