Abstract
The invention discloses a kind of quick hydrogen embrittlement inspection method of steel part and device.The present invention is using the method for the cooling for quickly heating the quick flames of war, allows the part of hydrogen embrittlement to crack, and such mode just judges that the hydrogen embrittlement of this batch of part is inclined to by detecting the crackle of part.This is a kind of fast and convenient detection method, can be applied to production scene, and this method is low for equipment requirements, and can also fast and accurately be detected for part as spring.
Description
Technical field
The present invention relates to material rapid detection technical field, is specially a kind of quick hydrogen embrittlement inspection method of steel part and dress
Put.
Background technology
Harm of the hydrogen embrittlement of steel to hardware is very big.The many links of steel part in production.Such as raw material
The Alternative processes such as production, plating, pickling, may all suck protium.Protium can cause the hydrogen embrittlement of steel.
The content of what kind of quick detection hydrogen, or it is relatively difficult.Typically now all it is to use hydrogen content measuring instrument.But
It is that hydrogen content is this magnitude of hundred a ten thousandths in steel.It is the difficult survey of comparison, the instrument of special measurement hydrogen content, is to compare
Expensive.Content is also without corresponding standard.
The inspection of general hydrogen embrittlement, if bolt, these are typically all to use stress delay method.Applying certain answer
Power, is kept for a period of time.See whether delayed fracture.The shortcomings that this method of inspection is test period length, for firm part also
Relatively good operation at last.But for spring, this is just relatively difficult, particularly a little bit smaller spring.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of quick hydrogen embrittlement inspection method of steel part and device, its energy
Quickly judge that firm part whether there is hydrogen embrittlement, with overcome the deficiencies in the prior art.
In order to achieve the above object, the present invention is achieved by the following technical programs：The quick hydrogen embrittlement inspection method of steel part,
Include the following steps：
1) steel part is heated to 850-950 DEG C using high-frequency heating apparatus；
2) steel part after heating is immediately placed in cooling bath and is cooled down；
3) magnetic crack detection is carried out to steel part immediately using magnetic crack detector, checks whether steel part cracks, to sentence
Disconnected steel part whether there is hydrogen embrittlement.
The quick hydrogen embrittlement check device of steel part, including high-frequency heating apparatus, the composition of the high-frequency heating apparatus include
High frequency electric source, is equipped with high frequency heating coil in the output terminal of high frequency electric source, fixture is equipped with the top of high frequency heating coil, in height
The lower section of frequency heating coil is equipped with cooling bath；It is additionally provided with magnetic crack detector.
It can cause the principle of hardening flaw using hydrogen embrittlement.The quick method and apparatus for examining hydrogen embrittlement of invention one.
Beneficial effect
Compared with prior art, the present invention is that allowing has the zero of hydrogen embrittlement using the method for the cooling for quickly heating the quick flames of war
Part cracks, and such mode just judges that the hydrogen embrittlement of this batch of part is inclined to by detecting the crackle of part.This is a kind of fast
Fast easy detection method, can be applied to production scene, this method is low for equipment requirements, and can also be for as spring
Part is fast and accurately detected.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
The embodiment of the present invention：The quick hydrogen embrittlement inspection method of steel part, includes the following steps：
1) steel part is heated to 850-950 DEG C using high-frequency heating apparatus；
2) steel part after heating is immediately placed in cooling bath and is cooled down；
3) magnetic crack detection is carried out to steel part immediately using magnetic crack detector, checks whether steel part cracks, to sentence
Disconnected steel part whether there is hydrogen embrittlement.
The quick hydrogen embrittlement check device of steel part, including high-frequency heating apparatus 1, the composition bag of the high-frequency heating apparatus 1
High frequency electric source 1-1 is included, high frequency heating coil 1-2 is equipped with the output terminal of high frequency electric source 1-1, in the upper of high frequency heating coil 1-2
Side is equipped with fixture 2, and cooling bath 3 is equipped with the lower section of high frequency heating coil 1-2；It is additionally provided with magnetic crack detector 4.
In order to verify the technique effect of the present invention, inventor is during in March, 2017-May, in military enterprise of Guizhou Province
100 batch of grab sample, method and apparatus using the present invention is detected, and after detection, finds the sample with the presence of 11 batches
The situation of cracking, then, inventor use enterprise in hydrogen content measuring instrument all parts that detected are analyzed, as a result with
It is using the conclusion that detects of the present invention completely the same, it was demonstrated that the present invention has fabulous accuracy, but detection time is very big
Save, and it is extremely low to equipment requirement.
In the present invention, the selection of fixture is determined according to the part specifically detected.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of changes, modification, replace
And modification, the scope of the present invention is defined by the appended.
