在井式气体渗碳炉内进行渗碳过程中,有可能产生温度差异影响渗碳质量。产生马弗罐内上下区温差的原因有: (1)对测温仪表进行校表和定温有问题。 (2)在生产过程中由于马弗罐移动或炉子振动等原因,使热电偶位置发生移动,因此仪表反映不出炉罐内实际温度。 (3)热电偶长期使用有不同程度的损坏。 During the carburizing process in a pit-type gas carburizing furnace, it is possible that the temperature difference will affect the quality of carburizing. Produced muffle tank temperature difference between the upper and lower areas are: (1) temperature meter calibration and temperature problems. (2) The position of the thermocouple moves due to the movement of the muffle or the vibration of the furnace in the production process, so the meter does not reflect the actual temperature in the furnace. (3) Long-term use of thermocouples have different degrees of damage.
