DEVICE FOR MEASURING TEMPERATURE AND METHOD OF MEASURING TEMPERATURE OF MOLTEN METAL Russian patent published in 2020 - IPC G01J5/02 G01J5/00 G01K1/12 G01K13/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment and can be used for measuring temperature of molten metal. Disclosed is a temperature measurement device, which comprises a temperature-sensitive element, supporting tube (2), connection tube (4) and an exhaust structure. At that, temperature-sensitive element contains metal-ceramic tube (1), one end of which is closed, and the other one is open, wall thickness of metal-ceramic tube (1) is less than thickness of wall of supporting tube (2) and metal-ceramic tube (1) is configured to sense temperature of molten metal and emit stable heat energy of radiation based on the principle of cavity of absolutely black body when in molten metal. Open end of metal-ceramic tube (1) is rigidly connected to one end of supporting tube (2), metal-ceramic tube (1) is connected to supporting tube (2), and other end of supporting tube (2) is rigidly connected to connecting tube (4). Exhaust structure is configured to remove smoke contained inside metal-ceramic tube (1) and supporting tube (2). When the temperature of the molten metal is measured, the temperature measuring device is inserted into the molten metal to a depth greater than or equal to 8 times the outer diameter of the metal-ceramic tube.

EFFECT: providing continuous measurement of molten metal temperature with high rate of response.
