Magnetic analysis and testing technology of building forgings

As an important engineering material, building forgings are widely used in Bridges, high-rise buildings, water conservancy projects and other fields. Its excellent mechanical properties and corrosion resistance make it occupy a pivotal position in the construction industry. However, because the production process of forgings involves a variety of complex environments such as high temperature and high pressure, it is easy to lead to internal defects and seriously affect product quality. Therefore, the magnetic analysis and testing of building forgings is of great significance to ensure its quality.

Related technology introduction

In the field of building forgings testing, traditional magnetic testing, electromagnetic testing, surface acoustic wave testing and other technologies have been widely used. Among them, the traditional magnetic detection mainly through magnetic powder or yoke detection, can find cracks, inclusions and other defects on the surface of the forging. Electromagnetic detection is carried out through the principle of electromagnetic induction, with high detection speed and accuracy. Surface acoustic wave (SAW) inspection uses the characteristics of sound wave propagation on the surface of the material to detect the defects on the surface and near the surface of the forging.

Magnetic analysis

The magnetic characteristics of building forgings mainly include magnetization, permeability, saturation magnetic induction and other parameters. The change of these parameters will affect the behavior of the forging in the magnetic field, and then reflect the quality of the forging. Through magnetic analysis technology, it is possible to evaluate whether there are defects inside the forging, the uniformity of the material, the heat treatment effect and other key information.

Test technology application examples

In practical application, the magnetic analysis and detection technology of building forgings has been widely verified. For example, in the inspection of a number of steel piers for Bridges, it was found that some steel piers had serious internal defects through magnetic analysis. Further electromagnetic and surface wave detection confirmed the existence of these defects. By taking remedial measures in time, possible safety accidents are avoided.

Another application example occurs in the detection of elevator track forgings in high-rise buildings. By using magnetic analysis and electromagnetic detection technology, surface and internal defects of some elevator track forging parts have been found successfully. By repairing these defects, the safety and stability of the elevator track are ensured, and the safe operation of high-rise buildings is guaranteed.

conclusion

In summary, magnetic analysis and testing technology plays an important role in the quality control of building forgings. By analyzing the magnetic characteristics of the forgings, the quality of the forgings can be evaluated effectively and the defects and potential risks can be found. At the same time, combined with a variety of detection technology means, can improve the accuracy and efficiency of the detection, to ensure the quality and safety of building forgings provided a strong support.

outlook

With the development of science and technology, the application of magnetic analysis and testing technology in the quality control of building forgings has a broad prospect. In the future, more sensitive and efficient magnetic detection equipment and algorithms can be developed to improve the accuracy and speed of detection. At the same time, attention should be paid to the development of new non-destructive testing technologies, such as infrared testing, laser ultrasonic testing, etc., in order to further enrich and improve the detection means of building forgings.

In addition, it is imperative to establish a more perfect magnetic analysis and testing standard system. By standardizing the technical application process, clarifying the testing items and judging basis, the operability and reliability of the technology can be further improved, and a more solid foundation can be provided for ensuring the quality and safety of building forgings.
