摘　　要：值是评价深冲钢板成型性能的重要指标之一。值的在线无损连续检测对沿整个板卷长度方向实行质量监控极为有益。通过对目前的ｘ射线法和电磁超声法值在线检测技术各自特点的讨论，提出了电磁超声法更具发展前途的结论。value is an important index to the formability of deep-drawing sheet steet.value on-line measurement is of vital improtance for quility monitoring and controlling,In this paper,the features of the two popular methods,x-Ray method and EMAT method,are introduced respectively.Furthmore,through comparision,it is found that EMAT method is more promising than X-Ray method.
