Abstract

The invention relates to a high-temperature muffle furnace nine-time thermometry. Specifically, the high-temperature muffle furnace nine-time thermometry is used for achieving accuracy control of each area temperature in a high-temperature muffle furnace. The high-temperature muffle furnace nine-time thermometry comprises steps of getting the point, testing the stagnation temperature, looking up a table of the stagnation temperature test, testing aging temperature, looking up a table of the aging temperature test, comparing the stagnation temperature and comparing the aging temperature. The high-temperature muffle furnace nine-time thermometry is convenient for the accuracy control of the thermal ageing temperature of a catalytic agent, supplies reliable temperature data to a catalytic agent thermal ageing test, avoids abnormal fluctuation of the aging test, reduces the cost of repeating aging, saves the test time and improves the test efficiency.

Description

technical field [0001] The invention relates to a nine-point temperature measuring method for a high-temperature muffle furnace, in particular for realizing precise control of the temperature of each region in the high-temperature muffle furnace. Background technique [0002] High temperature muffle furnace is a general heating equipment, also called high temperature box furnace. At present, the high-temperature muffle furnace is mainly used for the aging of catalysts. Due to the long-term use of the high-temperature muffle furnace, the temperature difference between each position in the constant temperature zone of the high-temperature muffle furnace is large, and the temperature uniformity is poor; secondly, the set temperature deviates greatly from the actual temperature of each point; it seriously deviates from the initial aging temperature requirements The aging test fluctuates greatly, which brings many uncertain factors to the aging test.
