摘要
在近红外比色测温中,当炉内环境辐射强度高于被测工件辐射强度时,环境辐射对测量结果的准确性有显著影响。为了得到较为理想的测量结果,通过对被测工件在不同温度场下的投射辐射吸收率、反射率和透射率的分析,得出了几者之间的关系,为准确测量工件的实际温度提供了依据。在此基础上,提出一种新的解决高温背景辐射影响的方法。
In temperature measurement with near-infrared colorimetry method, when the environment radiation intensity in furnace is higher than that of work piece being detected, accuracy of measurement is influenced by environment radiation significantly. In order to obtain more reliable results, accordingto measurement analysis, the relationship was obtained between projected absorption rate of radiation, refiectivity and transmittance of the work piece detected in different temperature fields, which supplies theory basis for measuring the real temperature of work piece accurately. Furthermore, a novel resolution to eliminate background radiation in high temperature is proposed based on the results
