Title:
TEMPERATURE MEASUREMENT DEVICE AND TEMPERATURE MEASUREMENT METHOD FOR MEASURING TEMPERATURE OF MOLTEN METAL
Document Type and Number:
WIPO Patent Application WO/2019/000402
Kind Code:
A1
Abstract:
A temperature measurement device and temperature measurement method for measuring the temperature of molten metal. The temperature measurement device comprises a temperature sensing element, a support tube (2), a connection tube (4), and a ventilation structure. The temperature sensing element is a metal ceramic tube (1) having one closed end and one open end. When the metal ceramic tube (1) is inserted into molten metal, the temperature of the molten metal can be sensed on the basis of the black-body cavity principle, and stable thermal radiation energy is emitted. The open end of the metal ceramic tube (1) is fixedly connected to one end of the support tube (2), and the metal ceramic tube (1) has an interior in communication with an interior of the support tube (2). The other end of the support tube (2) is fixedly connected to the connection tube (4). The ventilation structure is configured to expel fume from within the metal ceramic tube (1) and the support tube (2). When measuring the temperature of molten metal, an insertion depth of the temperature measurement device into the molten metal should be greater than or equal to 8 times of an outer diameter of the metal ceramic tube (1).In this way, the present invention enables a fast response speed for consecutive measurements of the temperature of molten metal.
