Explanation of Temperature Field Distribution Detection Operation Data for Tubular Electric Furnace

If there is a microcomputer assistant during measurement, using the calculation and automatic drawing functions of Microsoft spreadsheet software in data processing will make testing the temperature field distribution of the tube furnace simpler and more convenient.
For newly installed and used resistance furnaces and repaired tube furnaces, it is necessary to test their axial temperature field distribution to facilitate adjustment and ensure the quality of thermocouple calibration. The tube furnace is one of the essential electric furnace equipment for identifying various industrial thermocouples. According to the verification regulations of thermocouples, qualified resistance furnaces must have a uniformly distributed temperature field, and the highest temperature zone must be located in the center of the furnace mirror.
There are three commonly used detection methods in China for testing the temperature field distribution of tubular furnaces: differential method and multi-point measurement method. Displacement method is relatively simple in operation and involves relatively few measurement equipment, but the errors generated in measurement are still relatively large.
For prefecture level measurement and testing institutes and many thermocouple projects that establish their own standards, displacement method is the main measurement method due to the prioritization of testing equipment and testing conditions, and the low requirements for the temperature field distribution of tube furnaces. The displacement method is a method of inserting standard thermocouples with length markings into the path cavity to measure the temperature field distribution in the furnace cavity at different depths. The disadvantage of this method is that it produces a large amount of data, which can be cumbersome to process.
