Analysis on Measurement and Analysis of Furnace Temperature Uniformity in the Furnace of High-temperature Furnace

How to calculate the furnace temperature in the furnace of a high temperature furnace. Many people probably don’t know how to answer it. Today, I will tell you how to analyze it.

Generally speaking, according to the requirements of the process and related technical documents, the maximum value, minimum value, and maximum deviation of the furnace temperature in the effective working area of ​​the box furnace can be obtained from the measurement results of the uniformity of the temperature of the high-temperature furnace. Value, maximum value and deviation of 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 the temperature can be seen.

The high temperature furnace is divided into two different components of the conductor at both ends to form a loop. When the temperature of the junction is different, an electromotive force will be generated in the loop. The thermocouple uses the principle of the electromotive force generated in the loop when the temperature of the two junctions are different to measure the temperature. According to the position distribution of the thermocouple in the furnace, the size and position of the effective working area of ​​the box furnace are determined.

1. The maximum deviation of furnace temperature = the highest temperature value in each measurement point-the lowest temperature value in each measurement 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.
