本文模拟了加氢反应器在停工或快速放空急冷过程中筒体的氢浓度分布,了解氢在材料内部的扩散规律,防止高的氢浓度导致材料在温度较低时发生氢致开裂,从而确定较为安全的冷却速度,对实际工程有很好的指导作用.
This article has simulated the hydrogenation reaction chamber,in the work suspension or blows off in fast the sharp quenching process the tube body's hydrogen density distribution,understood that the hydrogen in the material internal proliferation rule,prevents the high hydrogen density to cause the material when the temperature is low has the hydrogen to send the dehiscence,thus determined that the safer cooling rate,has the very good instruction function to the actual project.
