Research On Technique of Dual-Frequency Eddy-Current Inspection for Continuously Casting Hot Slab

College of Automation and Information Engineering, USTB, Beijing 100083 PRC

摘要: 采用二維渦流探傷模型,研究了渦流傳感器的結構參數對探傷靈敏度的影響,并將雙頻渦流探傷技術用于坯料表面缺陷檢測,結果表明,缺陷深度增加所引起的探頭阻抗變化使其相角發生變化。

Abstract: Two-dimension eddy current inspection model is taken for researching the effect of the eddy current transducer structure parameter upon the inspection sensitivity. Dual-frequency eddy current inspection is applied to the inspection of slab surface defects. The results of experiment prove that the change of sensor impedance due to the change of crack depth causes the phase angle of impedance to change.
