Description
Technical field
The present invention relates to a kind of magnaflux, especially relate to a kind of control software for intelligent magnetic particle flaw detector.
Background technology
Current, the magnetic powder inspection method at home and abroad every field of industry has all obtained using widely, the ultimate principle that magnetic detects is: when ferrimagnet is magnetized in magnetic field, the defective or the structural state variation on material surface and nearly surface can make local magnetoconductivity change, that is magnetic resistance increases, thereby make corresponding distortion of magnetic flux in the magnetic circuit: a part of magnetic flux directly passes through defective, part magnetic flux is walked around defective at material internal, some magnetic flux can leave material surface, walk around defective by air and reenter material again, therefore formed stray field at material surface.In general, surface crack is dark more, and the amplitude that leakage flux runs off material surface is high more, and is linear basically between them.
At the stray field place, the material surface because the magnetic line of force is come in and gone out and form the two poles of the earth (S, the N utmost point) in the defective both sides, if when spraying tiny ferromagnetic powder on this surface, place, surface leakage magnetic field can adsorb magnetic and form the magnetic trace, demonstrate defect shape, this is the ultimate principle that magnetic detects.
