Problems solved by technology

The disadvantage of this test method is that the test period is long, and it is relatively easy to operate for solid parts.
But for springs, this is more difficult, especially for smaller springs

Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0016] The embodiment of the present invention: a method for rapid hydrogen embrittlement inspection of steel parts includes the following steps:

[0017] 1) Use high-frequency heating equipment to heat steel parts to 850-950°C;

[0018] 2) Put the heated steel parts into the cooling tank for cooling immediately;

[0019] 3) Immediately perform magnetic flaw detection on steel parts with a magnetic flaw detector to check whether the steel par...

Abstract

The invention discloses a method and a device for rapid hydrogen embrittlement inspection of steel parts. The method and the device disclosed by the invention have the beneficial effects that cracks are generated on hydrogen embrittlement parts by adopting a cooling method of rapid heating and rapid fire, and in such a manner, the hydrogen embrittlement trends of the parts are judged through detecting the cracks on the parts. The method disclosed by the invention is a rapid, simple and convenient detection method, can be applied to a production field, is low in requirements for equipment and can rapidly and accurately detect the parts like springs.

Description

Technical field [0001] The invention relates to the technical field of material rapid detection, in particular to a method and device for rapid hydrogen embrittlement inspection of steel parts. Background technique [0002] The hydrogen embrittlement of steel is very harmful to metal components. There are many links in the production of steel parts. Such as the production of raw materials, electroplating, pickling and other processes, hydrogen may be absorbed. The hydrogen element can cause hydrogen embrittlement of steel. [0003] How to quickly detect the hydrogen content is still relatively difficult. Nowadays, hydrogen content measuring instruments are generally used. But the hydrogen content in steel is on the order of one part per million. It is more difficult to detect, and specialized instruments for measuring hydrogen content are more expensive. There is no corresponding standard for content. [0004] The general hydrogen embrittlement inspection, if it is a bolt, the...
