Embodiment 1
[0032] The method for verifying lateral defects of eddy current flaw detection specifically includes the following steps:
[0033] (1) The eddy current inspection line includes pay-off machine, straightener, shot blasting machine, eddy current inspection equipment, automatic painting equipment and drawing equipment along the direction of steel wire advance; the steel wire in production is pulled by the drawing equipment Travel along the direction from the pay-off machine to the drawing equipment; the eddy current flaw detection equipment includes a pass-through flaw detection module and a rotary flaw detection module, the pass-through flaw detection module is provided with a detection coil; the eddy current flaw detection equipment detects transverse defects on the steel wire passing through the detection coil detection;
[0034] (2) Select the steel wire surface at the front end of the eddy current flaw detection equipment and 1-2m away from the detection coil for transverse sc...
