Description
Technical field
The invention belongs to can quickly search the method for making sample of steel plate internal flaw, particularly one kind can quickly search steel
The method for making sample of intralamellar part defect.
Background technology
The domestic and international good equipment inlet plate line flaw detection instrument of similar section steel works condition, can automatic detection provide steel plate three
The individual defect distribution situation for attempting direction, can quickly determine the useless defect cause of flaw detection.
But because steel plate line flaw detection instrument price is high, equipment importation, every up to more than 60,000,000 yuan of quotation.Portion big absolutely
Steel splitting factory is only capable of carrying out steel plate carrying out flaw detection by hand-held defectoscope or double crystal probe, only all without online steel plate inspection instrument
Its defective locations can be determined by ultrasonic wave, but not can determine that the composition of detection defects.
In order to improve internal flaw to the adverse effect of plate quality, it is necessary to be divided in detail the defect inside steel plate
Analysis.Original method not can determine that the composition of detection defects to determine the defective locations inside steel plate using ultrasonic wave, because
This, it is impossible to the reason of internal flaw generation is analyzed, it is necessary to which a kind of sample method for making sample easily and effectively is particularly important.
The content of the invention
The method for making sample of steel plate internal flaw, the letter of its method can be quickly searched it is an object of the invention to provide a kind of
Just, it is easy to grasp, sample sample preparation person can be allowed easy to operate, and security is higher, it is possible to achieve to the defect inside steel plate
Labor is carried out, it is quick to search the reason for steel plate produces defect, improve the product quality of production steel plate.
The object of the present invention is achieved like this：It is a kind of quickly to search the method for making sample of steel plate internal flaw, just like
Lower step：
1st, determined after steel plate inspection defective locations, lacked by the way of gas flame cuttiug in steel plate by hand-hold ultrasonic defectoscope
Fall at position and extract sample, sample is shaped as cuboid sample, and the size of sample is sampling steel plate thickness * 300*200mm, so
Sample is placed in the small sample that sawing machine is processed into sampling steel plate thickness * 40*20mm afterwards；
2nd, at the thickness 1/2 of small sample, V-groove is processed along along its longitudinal peripheric surface, the A/F of V-groove is 5mm, depth
For 3mm；
3rd, the small sample for being machined with V-groove is placed under -40 DEG C of low temperature and freezed 30 minutes；
4th, the small sample after freezing, the test specimen body of its V-groove side is clamped on vice fixed and with hammer that its is another
Side is knocked off along the V-groove of small sample, obtains the sample body of 1/2 thickness of small sample；
5th, final sample is produced in the end face center position in sample body throwing direction, final sample is shaped as cuboid, its
Size is the thickness * 20*15mm of sample body, and final sample is placed in ESEM and analyzed.
This method includes following production stage：
（1）By the way that ultrasonic flaw detection steel plate sample is splitted along thickness 1/2, by the section at steel plate thickness 1/2
It is exposed, for carrying out section defect pattern and constituent analysis under ESEM.
（2）By hand-hold ultrasonic defectoscope, determine after steel plate inspection defective locations, taken by the way of gas flame cuttiug
Sample steel plate thickness * 300mm*200mm cuboid block sample, is subsequently placed in sawing machine and is processed into the small of steel plate thickness * 40mm*20mm
Sample.At the thickness 1/2 of small sample, V-groove is processed along surrounding, then sample is placed under -40 DEG C of low temperature and freezed 30 minutes.
（3）Sample one end is fixed with vice after freezing, and knocked off the other end along steel plate thickness 1/2 with hammer,
The sample produced, is the section of steel plate inspection defect thickness 1/2, the sample can be placed in ESEM and be analyzed.
The advantage that the present invention possesses：
The present invention, which possesses, quickly produces ESEM steel plate inspection defect sample, not only by detection defects at steel plate thickness 1/2
The form for sentencing surface is displayed, and cross-section morphology can be observed using the ESEM with energy disperse spectroscopy, it is possible to point
Chemical composition is analysed, is more beneficial for analyzing detection defects producing cause.
The present invention can be in the enterprise of steel mill without expensive line flaw detection instrument, the production slab steel sheet product for being equipped with ESEM
Industry is promoted, and is mainly used in the detection defects sample sample preparation of steel plate, coordinates ESEM quickly to search what steel plate inspection gave up
Reason.
The inventive method is easy, it is easy to grasps, makes sample sample preparation person easy to operate, and security is higher, realizes pair
Defect inside steel plate carries out labor, quick to search the reason for steel plate produces defect, improves the product matter of production steel plate
Amount.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention will be further described, and Fig. 1 is the small sample structural representation with V-groove
Figure, Fig. 2 is the sample position structural representation of final sample.
