| 摘 要： | 介绍一种热轧钢管冷态表面三维缺陷在线检测设备。该在线检测设备采用多路三维传感器,360°无死角对通过的钢管进行在线三维成像,通过设定缺陷深度、面积等阈值,可以对三维点坑类缺陷进行高精度识别。该设备检测热轧钢管冷态表面质量时,能有效弥补目前常用的接触式超声波检测、漏磁检测和涡流检测的检测短板。该设备还可以用于穿孔芯棒表面三维缺陷的检测。

| Abstract: | Described here in the essay is a system for on-line inspection of 3D surface flaw of the hot-rolled steel tube in cold state.Equipped with multi-channel 3D sensors,the on-line inspection system is capable of on-line 360°3D imaging for the tube as going through,and thus carrying hi-accuracy identification of the 3D pit defects via setting the thresholds like defect depth and area,etc.When used for inspecting the cold-state surface quality of the hot-rolled steel tube,the said system can well make up for the shortcomings as staying with the commonly-used inspection methods like the contact-type ultrasonic detection,the leakage flux testing and the eddy current inspection.Moreover the system can also be used to perform 3D flaw inspection of the piercing plug bar. |
