Description
Technical field
The utility model relates to the harmless UT (Ultrasonic Testing) technical field of medium plate, refers to particularly a kind of automatic flaw detection dynamic calibration test plate (panel).
Background technology
UT (Ultrasonic Testing) is one of main method of Non-Destructive Testing, what its utilized is material itself or the impact of inherent vice acoustic properties on ultrasonic propagation, in the hope of size, shape and distribution situation and the mensuration material character of non-destructive ground detecting material inherent vice (as crackle, bubble, be mingled with etc.).That UT (Ultrasonic Testing) has is highly sensitive, penetration power is strong, detection speed is fast, cost is low and the series of advantages such as harmless, therefore, it has been widely used in each industrial sectors such as machine-building, metallurgy, electric power, oil, chemical industry and national defence, and has become a kind of important means that guarantees product quality, guarantees equipment safety operation.
UT (Ultrasonic Testing) is divided into manual single channel ultrasonic wave flaw detection and hyperchannel automatic flaw detection pattern, compare, the operating process of manual single channel ultrasonic wave flaw detection is loaded down with trivial details, consuming time longer, detector device is affected by human factors larger with adjustment and the plate quality judgement of probe sensitivity, easily cause the shortcomings such as quality dispute, these all make hyperchannel automatic flaw detection pattern become gradually the Main Means of UT (Ultrasonic Testing), wherein, PUTS-ARS ultrasound wave automatic testing system is again to adopt one of more equipment in hyperchannel automatic flaw detection.This system can be carried out full automatic UT (Ultrasonic Testing) detection to medium plate, can accurately verify position, size and the form of steel plate inner inclusion, layering, shrinkage cavity, hole, white point, bubble, implosion, the tiny defect such as loose, have that efficiency is high, accuracy rate is high, standard is carried out high conformity, it is little and automatically sentence the advantages such as wound, automatic defect quantitative classification, automatic defect location to take production site, its ultrasound examination and evaluation capacity maintain the leading position in this area.
But this system is in verification operation process, and owing to belonging to dynamic calibration test plate (panel) and the difference of little test plate (panel) on surface state, material, the velocity of sound etc. of system, its Basic wave height and dynamic range exist inconsistency.Before this system is surveyed steel plate, need to after shutdown, carry out the reinspection of reference sensitivity, main spy and limit are visited to move to respectively in little test block separately and carry out, therebetween, when the probe of defectoscope runs to and aims at 5.0 millimeters of artificial defect flat-bottom hole verifications of ￠ on little test plate (panel), owing to there is certain difference in the surface smoothness of little test block and steel plate, so comparing with measured result, check results can produce certain deviation, cause reference sensitivity verification degree of distortion higher, and more than 100 probe needs verification one by one, not only operation is loaded down with trivial details, consuming time longer, and system reading out data is slower, reduced production efficiency.
The little test block high with respect to surface smoothness, dynamic calibration test plate (panel) and the steel plate material of system are more approaching, can utilize the dynamic calibration test plate (panel) of this system directly to carry out verification.Yet known referring to Fig. 1, the 5.6 millimeters of artificial defect flat-bottom holes 2 of ￠ that have two row's alternative arrangement on the plate body 1 of dynamic calibration test plate (panel), and the major function of 5.6 millimeters of artificial defect flat-bottom holes 2 of ￠ is the composite behaviours for testing tool (not shown) and double-crystal normal probe (not shown), can not be for the adjustment reference sensitivity of detecting a flaw.In actual production process, to regulate flaw detection reference sensitivity by the Sensitivity comparison test block (not shown) that is provided with 5.0 millimeters of artificial defect flat-bottom holes of ￠, according to the industry standard JB/T4730 of the People's Republic of China (PRC), when steel plate thickness is greater than 20mm, should be by the first reflection wave-wave height adjustment of 5.0 millimeters of artificial defect flat-bottom holes of the ￠ of measurement sensitivity reference block to full-scale 50%, using this as flaw detection reference sensitivity, during actual detection, when defect first reflection wave-wave is high while being more than or equal to full-scale 50%, can be judged to be defect.If and regulate flaw detection reference sensitivity with 5.6 millimeters of artificial defect flat-bottom holes 2 of the ￠ on dynamic calibration test plate (panel) plate body 1, can there is some difference with the adjusting result of 5.0 millimeters of artificial defect flat-bottom holes of ￠ of Sensitivity comparison test block, known by calculating, 5.6 millimeters of artificial defect flat-bottom holes of ￠ 2 with the sensitivity difference of 5.0 millimeters of artificial defect flat-bottom holes of ￠ are: 40 ㏒ 5.6/5.0=2dB, when the defect first reflection wave-wave high-amplitude of 5.0 millimeters of artificial defect flat-bottom holes of ￠ is 50%, according to relational expression 40 ㏒ H/50=2dB, 5.6 millimeters of artificial defect flat-bottom holes of known ￠, 2 first reflection wave-wave high-amplitude H are 44.6, being that 5.6 millimeters of artificial defect flat-bottom holes of ￠, 2 first reflection wave-waves are high only has 44.6% of full amplitude, lower than full-scale 50%, with regard to being easy to, cause the high defective hole between 44.6% to 50% of first reflection wave-wave to be considered normal hole and to cause detecting a flaw undetected like this, thereby cause the dispute of quality aspect, not only affect the accuracy that steel plate is judged, the interests of Ye Huigei enterprise cause damage.
Summary of the invention
