The establishment of a perfect quality traceability system is an important measure for modern heat treatment enterprises to guarantee product quality and improve management level, and the calibration of heat treatment furnace temperature field uniformity plays an indispensable role in it. The data recorded in each calibration process, including the measured value of the temperature sensor, calibration time, calibration personnel and other information, become the key basis for quality traceability.

When quality problems occur in a product, the calibration data can be traced back to pinpoint the time period when the problem arose, and determine whether it was due to the uncontrolled uniformity of the furnace temperature field that led to uneven heating of the workpieces, which in turn led to quality defects. This data not only helps to correct problems with the current batch of products, but also provides strong support for subsequent process improvement and optimization of the calibration process. At the same time, the calibration data and product batch, production orders and other information associated with the realization of the entire digital management, so that business managers on the production process at a glance, effectively improve the quality of the enterprise's management performance, enhance market competitiveness.
