| 摘 要： | 采用热重分析方法研究了600～750℃温度范围内,空气流速在1～10L/min范围内变化时IG-110核级石墨的氧化行为,分析了气体流速和温度对氧化速率的影响,并计算了相应的氧化动力学参数。实验结果表明IG-110石墨在空气中的氧化速率同时与反应温度和气体流速成正比,其中后者的影响效应随着温度的升高而增大。但相对来讲,在实验考察范围内,气流速度对IG-110石墨氧化速率的影响作用较弱,与温度升高带来的影响相比可以忽略。

| Abstract: | This study investigated the air oxidation behavior of IG-110 nuclear grade graphite at 600—750℃for gas flow rates of 1—10 L/min to calculate the kinetics parameters.The results indicate that the oxidation rate of IG-110 graphite increases with both temperature and flow rate,with the flow rate having a stronger effect at higher temperatures.However,the effect of the flow rate on the oxidation rate is much smaller than the effect of temperature. |
