Description

At present, a suitable method for surface inspection is magnetic powder inspection, which utilizes the interaction between the leakage magnetic field and the magnetic powder at the defect position of a workpiece, and utilizes the difference between the magnetic conductivity of the surface of a steel product and the magnetic conductivity of the near-surface defect (such as crack, slag inclusion, hairline and the like) and the magnetic conductivity of steel, the magnetic field at the discontinuous position of the materials is distorted after magnetization, and the leakage magnetic field is generated on the surface of the workpiece at the leakage position of partial magnetic flux, thereby attracting the magnetic powder to form magnetic powder accumulation-magnetic mark at the defect position, showing the defect position and shape under the proper illumination condition, and observing and explaining the accumulation of the magnetic powder, thus realizing the magnetic powder inspection.
