总结了我国自行研究、设计、制造的首台锻焊结构热壁加氢反应器成功安全运行１０年的经验。介绍了该反应器的主要技术参数及技术特点。指出我国加氢反应器研制技术有了很大的进步且实力逐步加强，如制造能力的提高、大型化的进展和反应器性能与质量的提高，以及大型化反应器现场组焊技术的开发成功等。为进一步改善现有Ｃｒ－Ｍｏ钢对环境强度的适应性而自行研制成功的３Ｃｒ－１Ｍｏ－１／４Ｖ新钢材已在１台新加氢反应器的制造中得到应用。
The experience of the first forged welded hot wall hydrogenation reactor, which was researched, designed and manufactured by our country, was successfully put into operation for 10 years. The main technical parameters and technical characteristics of the reactor are introduced. It is pointed out that the research and development of hydrogenation reactor in our country have made great progress and the strength has been gradually strengthened. For example, the improvement of manufacturing capacity, the progress of large-scale and the improvement of reactor performance and quality, and the successful development of large-scale reactor field welding technology Wait. A new 3Cr-1Mo-1 / 4V steel developed by ourselves to further improve the adaptability of existing Cr-Mo steels to environmental stresses has been used in the manufacture of a new hydrogenation reactor.
