漏磁场法在线定量检测钢丝裂纹的研究

On-line Quantitative Inspection of Cracks on Wire by Magnetic Leakage Flux Method

本文介绍了钢丝裂纹定量检测仪的工作原理及其组成。利用计算机辅助检测技术实现裂纹的准确定位和定量评价。该检测仪可应用于表面受油泥或其它非导磁性材料覆盖的钢丝的在线连续定量检测。

The principle and structure design of an quantitative instrument for cracks on wire are described. Accurate positioning and quantitative evaluation are achieved by the computer--aided inspection technique. The instrument can be used in on--line continuous inspection of wire covered with drilling mud or other non--magnetic matter.
