Theoretically, the heating time directly affects the temperature distribution and heating uniformity within a box-type resistance furnace. During the heating process in the resistance furnace, heat is generated through the resistance elements and transferred to the workpiece via heat conduction, convection, and radiation. A longer heating time allows the workpiece more time to absorb heat, theoretically promoting a more uniform temperature distribution between the inside and outside of the workpiece, thus improving heating uniformity.
However, the actual situation is far more complex than theory. The heating time is influenced not only by the performance of the resistance furnace itself but also by various factors such as the material, shape, and size of the workpiece, as well as the furnace atmosphere. For example, for workpieces with poor thermal conductivity, even a longer heating time may not achieve uniform heating both internally and externally; and for workpieces with complex shapes, the varying surface area to volume ratios lead to different heat exchange conditions in different parts during heating, thus affecting heating uniformity.
