Background technique
Gradually attention with people to product quality, the various measures for guaranteeing quality are put into effect in succession, to heat treated article
For, the key link of quality assurance is the test of heat preservation precision.GB/T30825 and AMS2750E is to furnace kiln system essence
Specific regulation, the end (test lead) of SAT thermocouple have all been done in degree test (systemic accuracy test hereinafter referred to as SAT)
76mm, and subsequent systemic accuracy test SAT should be no more than as close as, end distance with the end of test thermocouple
It should be consistent with initial test thermocouple placement location/position/depth with thermocouple.And smelter is produced into reduce
This, systemic accuracy test is typically chosen non-resident formula, for accurate test macro precision, carries out SAT before needing steel shove charge
With the preparation of thermocouple, there are reserved openings near test thermocouple first, SAT are inserted into thermocouple, into furnace
Insertion depth is observed, and measures actual range, it is long to result in the test preparatory period in this way, comes to the stove for there are multiple soak zones
It says, the disadvantages of thermocouple of preparation is more, and repetitive operation amount is big；And with the raising of in-furnace temperature, the thermocouple position SAT
It sets and is likely to occur change in location, cause the distortion of test result.
Summary of the invention
The utility model provides a kind of mounting structure of industrial furnace systematicness accuracy test thermocouple, solves existing skill
The defect of art.
