CONTINUOUS TEMPERATURE MEASURING DEVICE AND RH APPARATUS INCLUDING SAME Russian patent published in 2018 - IPC G01J5/28 G01J5/02 C21C7/10 G01K11/32 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of thermometry and can be used to measure the temperature inside a vacuum. Disclosed is a continuous temperature measuring device used in a Ruhrstahl-Heraeus (RH) process of performing vacuum degassing among steel making processes in an ironworks, and an RH apparatus including same. RH apparatus includes a sensor hole formed at a lower vessel of a vacuum vessel, a continuous temperature measuring device mounted on the sensor hole and including a light-to-temperature converter measuring temperature based on received light, a light guide rod receiving light from a measurement target, an optical fibre transferring the light received by the light guide rod to the light-to-temperature converter, a connector connecting the optical fibre to the light guide rod while maintaining straightness of the optical fibre, a primary protection tube enclosing an outer peripheral surface of the light guide rod, a flexible heat resistant tube protecting the optical fibre, and a joint connected to the flexible heat resistant tube and provided with a cooling gas injection tube, and a cooling gas supply unit supplying cooling gas to the cooling gas injection tube.

EFFECT: high accuracy and reliability of obtained data.
