Measurement and analysis of furnace temperature uniformity in high temperature furnace

Measurement and analysis of furnace temperature uniformity in high temperature furnace:

Generally speaking, according to the requirements of the process and relevant technical documents, the maximum and minimum temperature in the effective working area of the box furnace can be obtained from the measurement results of the uniformity of the furnace temperature, and the maximum deviation, maximum and maximum values of the furnace temperature The deviation of the minimum value from the set value of the browsing volume. However, the readings of the highest temperature value and the lowest temperature value in each measurement point should be selected during the entire measurement duration, not in the same measurement period. In this way, the time distribution characteristics of temperature can be seen.

The high-temperature furnace has two conductors with different components connected to a composite circuit at both ends. When the temperature of the junction is different, an electromotive force will be generated in the circuit. The thermocouple uses the principle of the electromotive force generated in the circuit when the temperature of the two junctions are different to measure the temperature. Determine the size and position of the effective working area of the box furnace according to the position distribution of the thermocouple in the furnace.

1. The maximum deviation of furnace temperature = the highest temperature value in each measuring point-the lowest temperature value in each measuring point.
2, the maximum deviation exceeding the set value = the highest temperature value in each measuring point-the set value of the controller.
3. The maximum deviation below the set value = the lowest temperature value in each measuring point-the set value of the controller.
