摘要
本文用热电偶误差计算的通用方法（极限误差表达法），分析了构成快速钨铼热电偶测温误差的因素，从量的角度探讨了各因素对总的误差的影响，对如何认识快速钨铼热电偶的测温精度，提出了可供参考的观点。
The sources of error for W/Rethermocouple probe in measurement of temperatureof molten steel are analysed by the general method oferror count for thermocouple(limit error countingmethod).The accumulative errors caused by thevarious source of error are described by quantitativeanalysis. The point of view is put forward forrecognizing the accuracy of W/Re thermocoupleprobe in measurement of temperature of moltensteel.
