MEASUREMENTS AND MODEL ANALYTICS FOR SPECTRAL BAND EMISSIVITY OF PURE ALUMINUM DURING THERMAL OXIDATION BELOW THE MELTING TEMPERATURE
ABSTRACT
Accurately measuring band emissivity in the spectral range from 8 to 14 μm is of significant importance in infrared radiation temperature measurements. The attempt of this study is providing emissivity data and analytical model for accuracy improvement of radiation thermometry in aluminum process industry. In this paper, a spectral band emissivity (8-14 μm) measurement apparatus for solid materials at temperatures between 423 and 1073 K was developed. The spectral band emissivity was calculated according to the improved algorithm proposed in our previous research to suppress the impact of the background radiation. The reference blackbody simulator was used to compute the spectral response function, and a strong linear response of the thermopile detector was obtained. The aluminum alloy 1060 (≥ 99.6 wt.%) was selected as targeted material, and the influence of thermal cycling history on its spectral band emissivity was discussed. The emissivity during thermal oxidation at given temperatures was systematically investigated. Analytical models versus the oxidation time were established to reveal the characteristics of emissivity during thermal oxidation. An optimal model which fits all emissivity curves below the melting temperature was finally selected. Analytical models are effective for temperature measurement in practice, and the results corrected by the analytical model are close to the true temperature values. The emissivity values obtained in this work will enrich the band emissivity data of pure aluminum and provide experimental basis for its application in radiation thermometry.
