Description
One: technical field
The utility model relates to a kind of leakage magnetic flow detector wear-resisting spy boots of amorphous.
Two: technical background
Leakage magnetic flow detector is mainly used in the online defects detection of weldless steel tube.The Magnetic Flux Leakage Inspecting system has the advantage that detectability is strong, automaticity is high, makes it become most widely used a kind of steel pipe online test method.Present domestic most of seamless steel tube production producer all adopts leakage magnetic flow detector to carry out online detection.Visiting boots is core parts of leakage magnetic flow detector, mainly carries out the detection of defect magnetic flux leakage field and the collection of signal.Visit boots in application process, must combine with the seamless tubular goods intimate, there are two shortcomings in this structure: the one, and visit boots and seamless tubular goods outside surface and have friction, relative motion is arranged again simultaneously, visiting the boots shell will constantly wear and tear; The 2nd, if mechanism pressure is bigger, aggravated to visit the wearing and tearing of boots, shorten the serviceable life of visiting boots.Thereby need carry out wear-resistant protection at spy boots inner arc and handle.
Wear-resistant protection processing mode commonly used at present mainly contains and installs the protective case of surface through thermal spraying treatment additional, and spray paint mainly adopts Fe-Ni, Ni-Cr base alloy, to improve its anti-wear performance.This technology is relatively complicated, spraying porosity and the bad grasp of thickness, and micropore, crackle appear in coating easily, and the metallurgical binding situation of coating and matrix is also unstable.It only is suitable for straight spy boots simultaneously, does not adopt this technology for the spy boots with certain radian.The spy boots that adopt substantially all have certain radian at present, to obtain the omnibearing defect detection of steel pipe.The processing mode that this spy boots adopt is to visit boots inner arc installation wear-resistant block, and the wear-resistant block material mainly adopts Hardmetal materials.This wear-resistant protection processing mode can effectively improve visits boots serviceable life, is spy boots wear-resistant protection material commonly used at present.But there are two problems in it, the one, and hard alloy steel material impact toughness is relatively poor, only is 10-30kJ/m
2, the impact, the vibration that take place in visiting the boots testing process can make the hard alloy steel wear-resistant block peel off, and the exfoliation meeting forms scratch to the steel tube surface that detects, and influences steel tube surface quality; The 2nd, the wimet steel substantially all has ferromagnetism, thereby magnetization easily has considerable influence for the precision of visiting the boots whole detection under the exciting field situation, when serious even cause Signal-to-Noise to cross low and can not use.Based on above 2 points, adopt hard alloy steel wear-resistant block material, though improve a lot, can increase the service life for visiting the boots wearing quality, can reduce the degree of accuracy of visiting the boots signal, simultaneously steel tube surface quality there is certain influence.
Non-crystalline material is a kind of new function material that rises in recent years.Amorphous alloy is meant that the three dimensions of its atom when solid-state is arranged and is topological disorder, and keep the metastable alloy of this state in certain temperature range.With respect to crystal alloy, there are not crystal defects such as crystal boundary, dislocation, fault in this structure, has the physical chemistry more excellent than corresponding crystalline material, performance.Reach 1808MPa as the large block amorphous tensile strength of ZrTiCuNiBe, maximum bending strength reaches 3700MPa, the high about order of magnitude of more general crystal alloy and plow-steel, and composite bending modulus 147GPa, Vickers hardness reaches 580.Inoue adopts the summer to study the impact flexibility of ZrAlCuNi non-crystaline amorphous metal than U-shaped notched specimen, and its maximum impact energy to failure reaches 63kJ/m2

20(x=0-5) impact fracture of bulk amorphous alloys can be up to 120～135kJ/m
2Along with the further investigation of bulk amorphous alloy and compound substance thereof, it uses the attention that also more and more is subjected to various countries, and this amorphous and compound substance thereof have bigger glass forming ability and be also referred to as metallic glass.Because the abrasion resistant qualities of low friction, high strength and the enhancing of metallic glass, block metal glass is elected as the drill bit containment vessel material that next mars exploration is drilled rock in the works by NASA.
Three: summary of the invention
It is base block amorphous as visiting boots wear-resistant protection material that the purpose of this utility model provides a kind of employing Zr; can overcome the shortcoming of wimet high-abrasive material; have better anti-wear, vibration and shock resistance; can effectively protect steel tube surface quality; simultaneously because it does not have ferromagnetism; can effectively improve and visit the boots signal to noise ratio (S/N ratio), and then improve the leakage magnetic flow detector wear-resisting spy boots of amorphous of signal accuracy.
The purpose of this utility model realizes in the following manner:
The utility model comprises visits the boots body, it is characterized in that: be inlaid with the base block amorphous wear-resistant block of Zr at the intrados of visiting the boots body.
It is that amorphous alloy material is manufactured that the base block amorphous wear-resistant block of described Zr can adopt ZrAlCuNiBe system, ZrAlNi system, ZrCuNiAl system, ZrCuNiAlTi system, ZrCuNi system or ZrAlCuNiNb.
The base block amorphous wear-resistant block of described Zr is the cylinder bodily form, and diameter is Φ 4-8mm, and thickness is 3-5mm.
The utility model has the advantages that:
1, Zr bulk amorphous alloy material has higher hardness and compressive strength, has rub resistance polishing machine preferably under the less situation of radial pressure.
2, the base block amorphous material of Zr has higher impact flexibility, impacting, vibrating under the operating mode, surperficial large tracts of land can not take place peel off, and causes the scuffing to steel pipe.
3, because the base block amorphous material of Zr does not have ferromagnetism, under excitation field, can not introduce new noise source to visiting boots, can effectively improve and visit the boots signal to noise ratio (S/N ratio), and then improve and visit the boots signal accuracy.

Five: embodiment
As shown in Figure 1 and Figure 2, the base block amorphous wear-resistant block 2 of Zr is installed in the intrados of visiting boots body 1, is distributed in circuit signal picking up system both sides.It is Zr that the base block amorphous wear-resistant block 2 of Zr adopts alloying component
