Measurement results of temperature uniformity of high temperature box furnace

The maximum and minimum temperature in the effective working area of the box furnace, the maximum deviation value of the furnace temperature, the deviation between the maximum and minimum values and the set value of the flux can be calculated. 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 box furnace consists of two conductors with different components connected to a combined 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 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.
