Technical field
The present invention relates to magnetic metal material detection means, more particularly to a kind of automatic warning device of detection ferromagnetic material crack.
Background technology
At present, in ferrimagnet production process, outside due to the effect of the external loads such as external force, vibrations, ferrimagnet is easy for crackle occur, this has not only slackened the mechanical strength of ferromagnetic metal material significantly, once and if using plant equipment and engineering equipment in, just very likely with outer power load continuous action continue expansion, so as to cause the failure of part, finally hidden danger is brought to the safety of plant equipment and engineering equipment；In order to effectively detect the crackle of ferrimagnet parts in process of production, people have invented various detection methods, have just included among these：Ray detection, ultrasound detection, EDDY CURRENT, acoustic emission detection and leakage field etc.；In terms of battery detecting, the instrument and probe of material classification and crack detection has been there are in prior art, but in technological means, the quasi-instrument is in detection process, the direction of exciting field is invariable, even if change also be only tri- directions of X, Y, Z switching, and pop one's head in three directions on detection be it is separate, without constitute an organic whole.And due to the eddy-current loss caused by the crackle end face vertical with magnetic direction it is less, therefore existing probe can effective detection X, Y, the crackle section on tri- directions of Z, and then effect is poor to the crackle on other directions.
Can there is macroscopic cracking to parts mostly and effectively be detected in above-mentioned instrument and method, and the routine techniquess means of industrial circle are had become at present, but the deficiency of its general character be this quasi-instrument normally can only be to having been formed crackle detect that the tissue defects to not having crackle but have cracking tendency can not typically carry out effective detection and provide early warning information.Found by retrieving, the research of current this aspect is relatively limited, and there is no effective detecting instrument.
In practical application, outside due to the effect of the external loads such as external force, vibrations, parts once form crackle, Rapid Expansion is possible to, so as to reduce rapidly the strength of materials, cause great potential safety hazard, especially for the in-service key components and partss of the great products such as aircraft, high ferro, wind-powered electricity generation, Grand Equipments and Important Project for, early find and detect potential crack meaning it is especially great.
