Problems solved by technology

[0007] The purpose of the present invention is to provide a hydrogen embrittlement detector for the production of high-strength steel, so as to solve many uncertain factors in the existing device. It may cause simple fracture of the steel when it is deformed for a long time, instead of hydrogen molecules inside it. The damage caused, and because the detection time takes 30 minutes or as long as several hours, the visual fatigue of the inspectors is caused, and the inspectors cannot observe for a long time or it is difficult to compare

Embodiment 1

[0039] When installing, producing or assembling this device, it is necessary to set and open the steel reinforcement limiter 3 and the steel entry hole 23 on the same horizontal line, and the steel reinforcement limiter 3 and the steel entry hole 23 are symmetrically installed in the detection On the main body shell 1 of the device, one end and the other end of the steel are fixed on the steel reinforcement limiter 3 and the steel entry hole 23. At the same time, the recording camera 10 needs to be aimed at the steel. The recording camera 10 records need no dead angle, and The traversing motor 22 is fixed on the other surface inside the main body shell 1 of the detector through the traversing slide rail 15, and the steel-driven bump 33 is a bump made of an 'I' shape, and the steel-driven bump 33 is the inside of the end face. Nested with a vibration detection sensor 34, the steel needs to be raised before detection. An 'I'-shaped clamping groove is provided on the end face, and...

Embodiment 2

[0041] And the steel reinforcement limiter 3 includes a steel main body wrapping shell 31, a steel material entry groove 32, and the steel material drives a bump 33 and a vibration detection sensor 34, and a steel material entry groove 32 is provided in the steel material main body wrapping shell 31, and a steel material entry groove 32 is provided with a steel material entry groove 32. Drive the bump 33 and the vibration detection sensor 34, the steel main body wrapping shell 31 is connected with the drive shaft on the drive motor on the outer surface of the detector main body shell 1, and the debris processing assembly 7 includes a debris removal body 71, and a moving cleaning rod 72, Restricting block 73 and cleaning power motor 74, one end of two mobile cleaning rods 72 passes under the both sides of the debris removal body 71, the debris removal body 71 is a pushing body made in an 'M' shape, and the debris removal body 71 The inner shape is a concave arc, and one end of t...

Embodiment 3

[0043] A kind of steel hydrogen embrittlement test device that National Patent No. CN 212674599 U involves, the time required for detection is as follows: severe hydrogen embrittlement steel --- fracture time is several minutes to several hours, higher hydrogen embrittlement steel -- --Steel with a fracture time of several hours to tens of hours and low hydrogen embrittlement (qualified steel) ---The fracture time is tens of hours to hundreds of hours, and the time required for the detection of this device is as follows: serious Hydrogen embrittlement --- fracture time is a few minutes to 7 hours, higher hydrogen embrittlement --- fracture time is 7 hours to 25 hours, lower hydrogen embrittlement --- fracture time is 25 hours to 70 hours, from the above data It can be seen that the hydrogen embrittlement device only needs 70% of the time of the above-mentioned device to complete the detection of its steel, which is convenient to reduce the large amount of time required for the ...

Abstract

The invention discloses a hydrogen embrittlement detector for high-strength steel production, which comprises a detector main body shell, and is characterized in that four instrument supporting legs are respectively arranged at four corners of the lower surface of the detector main body shell, the number of the instrument supporting legs is four, and a steel reinforcing limiter is mounted on the inner surface of the detector main body shell; and the driving motor is connected with the steel reinforcing limiter through a bearing. According to the invention, the situation of fracture caused by deformation or insufficient metal fatigue strength in the prior art can be avoided, visual fatigue caused by long-time observation of detection personnel can be avoided, and the use experience and effect can be optimized conveniently.

Description

technical field [0001] The invention relates to the technical field of steel hydrogen embrittlement, in particular to a hydrogen embrittlement detector for high-strength steel production. Background technique [0002] Hydrogen embrittlement is hydrogen dissolved in steel, which aggregates into hydrogen molecules, causing stress concentration, exceeding the strength limit of steel, and forming small cracks inside the steel, also known as white spots. Hydrogen embrittlement can only be prevented, not cured. Once hydrogen embrittlement occurs, it cannot be eliminated. In the smelting process of materials and the manufacturing and assembly process of parts, such as electroplating and welding, the trace amount of hydrogen entering the interior of steel will lead to material embrittlement or even cracking under the action of internal residual or external stress. [0003] The catastrophic brittle fracture induced by hydrogen in high-strength structural steel under relatively low s...
