Description

A kind of pickling detection means of test button half

Technical field

It the utility model is related to a kind of test button pickling detection device, more particularly to a kind of pickling of test button half detection Device.

Background technology

It is using a kind of relatively more extensive defect inspection method in steel industry that hot acid, which washes detection,.This method is to try metal Sample is immersed in the acid solution of certain temperature and concentration, the chemistry using acid solution with materials such as oxidation on metal surface iron sheets Reaction, is eroded to specimen surface to manifest specimen surface defect.

Hot acid, which washes detection method, has the characteristics that simple to operate, result intuitive display, but the traditional detection method exist with Lower drawback：First, pickling detection belongs to destructive detection, and the overall reset condition of sample can not retain, and can not reappear defective part The primary morphology of position；Secondly, after hot acid is washed although specimen surface defect appears, but the defects of same sample correspondence position by Corroded in by acid solution, the micro-analysis such as metallographic, Electronic Speculum can not be carried out again, be unfavorable for the micro- of comprehensive descision specimen surface defect See feature；Above drawback influence technique personnel are unfavorable for the horizontal lifting of Product checking to the quick detection of steel products defect.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of pickling detection means of test button half, can be to sample The latter half carry out pickling detection, while reserve sample top half primary morphology, by analyzing the latter half acid-washing region table Microscopic feature the defects of top half latent defect area, quick and precisely judges defect producing cause corresponding to area linear defect.

Technical scheme is used by the utility model：

A kind of pickling detection means of test button half, including support, chain, magnet and beaker；The support includes one Taper lid, through hole is provided with the top of taper lid；The chain pass through taper lid through hole, chain one end fixed magnet, The other end opens；The beaker is placed in below taper lid.

A kind of above-mentioned pickling detection means of test button half, the taper lid are cone, the taper lid vertex of a cone Through-hole diameter is more than diameter chain, and cone floor space is more than beaker cross-sectional area；The support also includes at least three poles, and three Bar pole one end is equidistantly fixed along conical lid lower circumference, and pole and the axis of taper lid are parallel to each other, pole Length is more than beaker height.

The utility model application method is：Acid solution will be injected in beaker first, made in the axis and taper lid of beaker Axis overlaps；By sample to be tested upper surface magnet adsorption, regulation chain length makes the latter half of sample immerse in acid solution, root The pickling that sample is carried out according to acid solution detection temperature heating acid solution needed for sample detects.Sample the latter half is by acid solution after detection Corrode, show the linear discontinuities such as face crack, folding；Because sample top half is not corroded by acid solution, so can retain Primary morphology；The microcosmic detections such as metallographic, Electronic Speculum are carried out to sample top half sampling corresponding to the defect of sample the latter half, you can The internal feature of correspondence analysis surface defect, technical staff can quick and precisely judge that defect is produced by both macro and micro detection and analysis Raw reason.The utility model taper lid can play a part of insulation, prevent acid solution volatilization pollution environment；Three pole one end Equidistantly fixed along conical lid lower circumference, it is ensured that the stability of taper lid.

The beneficial effects of the utility model are：

The utility model can be achieved the pickling detection of test button the latter half, protect simultaneously by adjusting the length of chain Stay the primary morphology of top half；Sample top half latent defect area corresponding to the defect of sample the latter half acid-washing region is sampled Carry out the microcosmic detections such as metallographic, Electronic Speculum, you can the internal feature of correspondence analysis surface defect, technical staff pass through both macro and micro Detection and analysis can quick and precisely judge defect producing cause.The utility model is simple in construction, easy to operate, cost is cheap, promotes Have a extensive future.

In figure mark for：Support 1, chain 2, magnet 3, beaker 4, conical lid 5, pole 6, through hole 7, sample 8, surface Defect 9, latent defect area 10, acid-washing region 11, pickling line 12, non-acid-washing region 13.

Embodiment

Fig. 1 and Fig. 2 show, a kind of pickling detection means of test button half of the utility model, including support 1, chain 2, magnetic Iron 3 and beaker 4；Support 1 includes a conical lid 5 and pole 6, and the top of conical lid 5 is provided with through hole 7；Pole 6 is Three size identical round bars, the lower circumference of one end of three poles 6 along conical lid 5 are equidistantly fixed, three poles 6 with The axis of conical lid 5 is parallel to each other, and ensures overall stability of the present utility model；The length of pole 6 is more than beaker 4 Highly；Chain 2 opens through the through hole 7 on conical lid 6, one end fixed magnet 3 of chain 2, the other end；Beaker 4 is placed in The conical lower section of lid 5 and the axis of beaker 4 and the coincidence of the axis of conical lid 5；Fig. 1 shows that conical lid 5 is bored The diameter of the through hole 7 on top is more than the diameter of chain 2, facilitates chain 2 freely activity, conical lid 5 in through hole 7 to bore floor space More than the cross-sectional area of beaker 4；Ensure that conical lid 5 can play insulation and prevent acid solution volatilization pollution ring in acid cleaning process The effect in border.

It is of the present utility model to be using process：Acid solution will be injected in beaker 4 first, make axis and the cone of beaker 4 The axis of lid 5 overlaps, and purpose can be located at the center of beaker 4 for guarantee sample 8；By the upper surface of sample to be tested 8 magnet 3 Absorption, the length of regulation chain 2 makes the latter half of sample 8 immerse in acid solution, according to acid solution detection temperature needed for the steel grade of sample 8 Heat the pickling detection that acid solution carries out sample.

Fig. 3 shows that sample 8 forms the latter half acid-washing region 11 of clear-cut, the non-pickling of top half after detection Area 13 and the pickling line 12 formed by acid solution surface erosion.By acid-washing region 11 is corroded by acid solution, surface defect is shown 9；And non-acid-washing region 13 is capable of the primary morphology of reserve sample 8 due to not corroded by acid solution；To surface defect 9 in non-acid-washing region 13 The corresponding sampling of latent defect area 10 carries out the microcosmic detections such as metallographic, Electronic Speculum, you can the interior microscopic of correspondence analysis surface defect 9 Feature, technical staff can quick and precisely judge defect producing cause by both macro and micro detection and analysis.
