金属管缝跟踪装置的研制

Development of Tracking Equipment for the Seams of Metallic Tubes

本文针对无缝金属管材连续冷轧生产线上管缝检测这一课题，提出用电涡流法实现检测的可能性。并在实验的基础上，论述了如何设计传感器的问题。

The subject of this paper is to inspect the seams of the seamless metallic tubes on the continuous cold rolling production line. The possibility of inspection with eletro-eddy current method is put forward. The problem of the sensor design is discussed on the basis of experiments.
