The Study of Fine Tungsten Rhenium Thermocouple Wires in the temperature measurement of the molten steel

摘要：

　　In this paper, the producing methods of high precision Fine Tungsten-Rhenium Thermocouple wires and its applied research in the temperature measurement of the molten steel are introduced, The effects of Fine W-Re Thermocouple Wires on the fabrication technology, the temperature measurement precision and stability of the Quick Response Tungsten-Rhenium Thermocouple probe are discussed.The results show that the temperature measurement precision and stability of φ0.05mm Fine W-Re Thermocouple wires reach that of Type S thermocouple wires.The crack of W-Re Thermocouple wires can be avoided and the length of thermocouple wires can be cut more shorter in the process of manufacturing the Quick Response W-Re Thermocouple probe with φ0.05mm Fine W-Re Thermocouple Wires, so that the product yield and efficiency can be advanced.
