近年来,对线材表面质量的要求日益严格,一直在寻求一种表面缺陷检查精度高、缺陷修磨处理能力大的技术。为解决这一问题,新日本制铁所开发了采用涡流探伤机对线材表面缺陷进行检测,并使缺陷修磨自动化的新技术。过去,为保证对表面缺陷要求严格的线材质量,所采取的方法是:对线材 In recent years, the requirements of wire surface quality have become more and more stringent. We have been looking for a technique that has the advantages of high surface defect inspection accuracy and large defects grinding capacity. To solve this problem, Nippon Steel Corporation has developed a new technology that uses eddy current flaw detection machine to detect the surface defects of wires and automate the defect grinding. In the past, in order to ensure the strict quality of the surface defects of the wire, the approach taken is: wire
