Abstract
The utility model discloses an ultrasonic sound plate wave comparing testing block for investigating flaws of a steel plate and is mainly composed of a block body, filling material, a filling block, etc. The block body is taken from the flawless position of the steel plate tested and the proper position is determined to be milled out a groove port in fixed quantities. Then the limited area of the groove port is filled with any filling material being similar to or being identical with air, slag or inclusion and at last, the groove port is filled with the flawless filling block having the same material with the block body. Because the testing block is made according to various testing purposes, the testing wave shape of the testing block has strong simulation character. The testing result of the testing block passes through the anatomy actual measurement. The ultrasonic sound plate wave comparing testing block can test out the position of the flaws accurately and the tested error in area approaches to zero. The ultrasonic sound plate wave comparing testing block is also applied well in practice.
Description
The utility model relates to the reference block of a kind of steel-plate ultrasound wave inspection, belongs to Non-destructive Testing on Metal flaw detection important tool.
In field of metallurgy, the smelting of liquid metals and cast are involved in air, slag inclusion inevitably and are mingled with etc.Character that being involved in of these things will be become a useful person to metal and performance play and seriously influence.In the solid metal after rolling becoming a useful person, its air, slag inclusion and be mingled with and will exist in the form of sheets to be parallel to rolling surface.In accordance with international practices, the planar defective in the sheet metal will be limited in a certain scope by its size, otherwise will be by waste disposal.To the detection means of above-mentioned defective, normally carry out nondestructive examination with ultrasound wave, judge with the equivalent relative method again.Promptly allow the defect area of existence earlier by standard, the manufacture of intraocular defective constitutes reference block in steel plate.Record than the artificial defect in the test block with instrument earlier during the defect detecting test steel plate and get the comparison of wave shape that a reference waveform goes and quilt spy steel plate obtains, thereby whether qualified can determine to be visited steel plate.
Before the utility model was made, the artificial defect in the ultrasonic pl. reference block was the garden post through hole of a vertical panel face.And in esse sheet defective differs greatly to hyperacoustic reflection simulation in garden post through hole and the steel plate, thereby causes the inaccurate phenomenon of testing result, has reduced the reliability of testing result.
The purpose of this utility model is to have made the artificial defect reference block that in esse defective exactly likes in a kind of and the steel plate.So that testing result more accurate, trueer, have more practicality.
The planform of steel-plate ultrasound wave inspection of the present utility model reference block and result of use thereof and characteristics further specify as follows in conjunction with the accompanying drawings.
Accompanying drawing 1, figure is partly cutd open in the reference block of steel-plate ultrasound pl..
Test block for investigating flaws of steel plate when using ultrasonic testing of the present utility model mainly by block 1, is filled out Material 2, fill block 3 forms. Its block 1 has drawn from and is detected the zero defect part of steel plate, and definite appropriate location mills out notch quantitatively, the any filler 2 that insert again similar air, slag inclusion in limited notch, is mingled with is used with bulk to fill with material and flawless fill block at last. Because in esse defective exactly likes in the artificial defect in this test block and the steel plate, and the quantitatively accurate problem under the mode jump condition when being more suitable for pl..
Test block for investigating flaws of steel plate when using ultrasonic testing of the present utility model test block using method with routine on using method is identical, it is used in inspection center of north of China iron company, its effect is by dissecting actual measurement, and it is errorless not only can to detect defective locations, and area error levels off to zero. And obtained in practice using preferably.
Claims (1)
1, a kind of steel-plate ultrasound pl. reference block, mainly by block (1), filler (2), fill block (3) is formed, the have drawn from zero defect part of detected steel plate of the block (1) that it is characterized in that it, and definite appropriate location mills out notch quantitatively, and any filler (2) of inserting similar air, slag inclusion again in limited area or being mingled with is used at last and mended flat with block with material and flawless fill block (3).
