Taking an actual situation of resistance furnace in a heat treatment plant as a case, thermal performance defect of resistance furnace for special alloy during pyrometry test were introduced. Through the temperature 450, 620 and 780 ℃calibration of the set, the reason of the substandard survey of TUS and SAT are analyzed, as a consequence the furnace reach the pyrometric requirements in AMS 2750E class 2 by the technical modification and reformation.
