实验证明将两种不同材质的金属陶瓷棒作为测温热电偶的两极 ,置于液态金属中连续测量金属温度 ,其原理和方法是可行的。金属陶瓷棒组成的新型热电偶耐渣侵蚀性好、耐热震性强、输出热电动势值较大 ,在金属熔化温度范围内其热电动势与温度呈明显的线性关系 ,为高温液态金属的温度测量提供了一种新方法。
Experiments show that the two different materials as the thermocouple thermocouple two poles, placed in liquid metal continuous measurement of metal temperature, the principle and method is feasible. The new type of thermocouple composed of metal ceramic rods has good slag erosion resistance, high thermal shock resistance and large output thermoelectromotive force value. The thermoelectromotive force and temperature are obviously linear in the range of metal melting temperature, which is the temperature of high temperature liquid metal Measurement provides a new method.
