摘要:
为了快速检测出热轧板HIC试样中的夹杂和裂纹,并对缺陷进行准确定位、定性和测长,首先采用60°斜探头对夹杂和裂纹进行定位和定性,再用直探头检测出缺陷的长度,最后给出了夹杂和裂纹的静态和动态反射波形。该超声波判定技术可以用来确认试样是否符合标准要求,并进一步判定相应产品是否合格。与传统检测方法相比,该技术能够快速准确地定位和定性缺陷,并且定量精度由原来的2 mm提高至0.5 mm,能够满足API SPEC 5L的相关要求。
Abstract:
In order to quickly inspect the slag and crack in HIC specimen of hot rolled plate, and conduct accurate positioning, qualitative and length measurement for defects, firstly, it adopted 60°oblique sensor to carry out positioning and qualitative, and then used straight probe to detect defect length, finally gave the static and dynamic state reflection waveform of the slag and crack. The ultrasonic technology can be used to confirm the sample whether accord with standard requirements, and further determine the corresponding product is qualified. Compared with the traditional detection method, the technology can rapidly and accurately positioning and qualitative defects, and the quantitative accuracy was increased from 2 mm to 0.5 mm, can meet the requirements of the relevant API SPEC 5L.
