Spectral emissivity of 65Mn steel
摘要:
在800~1100K的温度范围内,采用单波长测温方法,利用自行研制的实验装置,在空气中测量研究了16个不同温度下65Mn钢的光谱发射率随测量时间的变化情况.研究结果表明光谱发射率的共振与65Mn钢的表面氧化情况密切相关.由表面氧化导致光谱发射率的不确定性为5.7%~14.6%,相应的温度误差为6.2~11.1K.通过建模拟合,同时也得到了光谱发射率随加热时间变化的解析表达式,模拟计算结果与实验结果符合较好.
In the temperature range of 800-1 100 K,the spectral emissivity of 65Mn steel at 16 different temperatures was measured by air in a self-developed experimental device using single-wavelength temperature measurement method.The results show that the spectral emissivity is closely related to the surface oxidation of 65Mn steel.The uncertainty of the spectral emissivity caused by surface oxidation is 5.7%-14.6%,which results in a temperature error of 6.2-11.1K.Through the modeling and fitting,the analytical expression of the spectral emissivity with the heating time is also obtained.The simulation results are in good agreement with the experimental results.
