Operation principle：
When being measured into trip temperature the cold-strip steel in continuous annealing furnace 1, in-furnace temperature generally exists because of material difference
Between 800-1200 DEG C.It typically precedes and opens up exploration hole on the furnace wall of continuous annealing furnace 1,4 front end of infrared radiation thermometer will be installed on
Sighting tube 3 be fixedly arranged in exploration hole and be observed.In order to avoid hot environment is to measuring the interference generated, the sighting tube 3
Front end be mounted on heat-insulated radiation coolant jacket 2, the heat-insulated radiation coolant jacket 2 is generally sleeve structure, both：Inner and outer tubes
Coaxial line is set in one, and air inlet pipe and an air outlet pipe is separately installed between inner and outer tubes, and cold nitrogen enters from air inlet pipe
The escape pipe outflow of tube top to after the tube bottom of heat-insulated radiation coolant jacket 2, then from heat-insulated radiation coolant jacket 2, forms heat-insulated radiation
Cooling circuit in coolant jacket 2.Because specific heat capacity is smaller compared with water for nitrogen, therefore, the nitrogen flowed out from heat-insulated radiation coolant jacket 2
Temperature is higher, generally up to 400-600 DEG C；
The nitrogen of outflow initially enters in first order nitrogen cooling line 8, after the processing of level-one cooler 5, is cooled to
At 200-300 DEG C, a part therein is sent in sighting tube 3, forms the air-flow to 3 bottom purge of sighting tube, can do detection mirror
Head purging air source；Another part enters in the air inlet pipeline 9 in the nitrogen cooling line of the second level, at secondary coolers 6
It is down to room temperature after reason, is passed into the cooling pipe in infrared radiation thermometer 4, is used as sensor cooling air source；It is come out from sensor
Nitrogen be pooled to again in sighting tube 3；Finally, whole nitrogen is entered by sighting tube 3 in continuous annealing furnace 1, is realized
The whole of resource recycle.On the one hand, it solves hot nitrogen and can not be recovered in original pipeline and go and diffuse in air, i.e.,
Wasting the energy again has the danger that height temperate zone is come；On the other hand, also solve collect dispersion nitrogen centralized processing and it is increased
Equipment investment problem.
