本文介绍能用于钢水测量的消耗式钨铼热电偶。它不仅能测2100℃的高温,而且可逐步替代铂铑系消耗式热电偶。实践证明,该热电偶有极为显著的经济效益。文中较详细地介绍了该装置的结构及其热电特性的标定等。
This article describes a consumable tungsten-rhenium thermocouple that can be used for measuring molten steel. It can not only measure the temperature of 2100 ℃, but also gradually replace the platinum and rhodium-based consumable thermocouple. Practice has proved that the thermocouple has a very significant economic benefits. In this paper, the structure of the device and the calibration of its thermoelectric properties are introduced in more detail.
