RADIATION THERMOMETRY OF METAL IN HIGH TEMPERATURE FURNACE

Abstract

This study aims to develop a practical radiation thermometry system of metals moving through in a high temperature furnace. In order to achieve this study, two problems; emissivity compensation of a target and elimination of background radiation noise filled in a furnace must be sorted out. We have successfully developed a method for simultaneous measurement of emissivity and temperature by use of polarized directional properties of the radiance from the target, in this case, stainless steel, and moreover a technique to eliminate background radiation noise using a pseudo blackbody installed in a furnace.
