During the implementation of the heat treatment process, the precision of calibrating the temperature field uniformity of heat treatment furnaces is directly related to the quality of the final product. Even a slight temperature deviation can cause metal workpieces to have completely different internal microstructures under the effect of high temperature for a long time.

The calibration work starts with the selection of high-precision temperature measuring instruments. The error range of these instruments must be strictly limited to a very small value to ensure the reliability of the obtained data. When arranging points inside the furnace, based on the geometric characteristics of the furnace body, the heating mode and past experience, the placement positions of the sensors are scientifically planned to strive to capture temperature field information in all directions. In the data acquisition stage, a high-speed and stable data acquisition system is used to prevent data loss or distortion. In the subsequent data analysis link, professional software is used to calculate the temperature uniformity index strictly in accordance with the established standards. Once it is found that the deviation exceeds the allowable range, the source of the problem is immediately traced back, either by adjusting the power of the heating elements or optimizing the air flow direction inside the furnace until the precision meets the standard, laying a solid foundation for the stable progress of the heat treatment process.
