Technical Field
[0001] This utility model relates to the field of non-destructive testing technology for steel center segregation, and in particular to a rapid non-destructive testing device for steel center segregation. Background Technology
[0002] Center segregation in steel refers to the phenomenon of uneven chemical composition occurring in the central part of a steel ingot or steel product. This means that the content of certain elements differs significantly between the central region and other areas. Center segregation leads to uneven mechanical properties in the steel, reducing its key performance indicators such as strength, toughness, and ductility. For example, in mechanical parts subjected to dynamic loads, the uneven performance caused by center segregation may lead to premature fatigue failure, affecting the reliability and service life of the entire equipment.
[0003] CN116067872A discloses a rapid non-destructive testing and evaluation device and method for the bonding strength of waterproof adhesive layers, including a specimen cutting tool and a pull-out testing tool. The specimen cutting tool includes a central cylinder and a cutting cylinder. A handle is provided above the central cylinder, and a cover plate is provided below it. The lower center of the cover plate has a concave structure, and a screw is provided on the cover plate. The lower part of the cutting cylinder has a serrated structure. The pull-out testing tool includes a support cylinder, and a pull rod is provided above the support cylinder. A hand hole is opened on the support cylinder, and a constraint ring is sleeved on the outside of the pull rod.
[0004] When in use, existing devices are difficult to inspect steel of different shapes, making it easy for the inspection device to collide with the steel during movement. In addition, existing devices can only move the inspection device in parallel, making it difficult to distinguish the segregation between the center and the outer side of the steel. Therefore, we propose a rapid non-destructive testing device for steel center segregation. Utility Model Content
[0005] In view of this, this application provides a rapid non-destructive testing device for steel center segregation, with the aim of solving the above-mentioned technical problems to a certain extent.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The electromagnetic sensor, based on the principle of electromagnetic induction, detects changes in the conductivity and permeability of the steel due to center segregation. The electromagnetic sensor can detect these changes in electromagnetic properties, thereby indirectly determining center segregation.

[0018] By adopting the above technical solution, the battery can power the electric telescopic pole, so that the electric telescopic pole does not need an external power cord.

The third motor drives the drive shaft and rotating plate to rotate, so that the steel center segregation testing device can rotate around the center of the steel. The electric telescopic rod is controlled to rise and fall and cooperate with the second connecting block and the second hanging ear, so that the angle of the steel center segregation testing device below can be adjusted. This device can perform rapid non-destructive testing for segregation of steel with different shapes.
[0021] This utility model discloses a rapid non-destructive testing device for steel center segregation. Through a steel center detection, processing, and display mechanism, an ultrasonic sensor utilizes the propagation characteristics of ultrasonic waves in steel. Since center segregation causes changes in the acoustic properties of the steel, such as sound velocity and attenuation, the device detects segregation by emitting and receiving ultrasonic waves and analyzing parameters such as the time and amplitude of the echo signals.

Then, it uses model-based data analysis methods, such as establishing ultrasonic propagation models and electromagnetic property models for normal steel structure and different degrees of center segregation, and compares and matches the collected data with the models to determine the location, range, and degree of center segregation in the steel. The visualization module can display the analyzed data graphically.

The high-speed data acquisition module 32, the data processing module 33, the ultrasonic sensor 34, the electromagnetic sensor 35, and the visualization display module 36 are all existing technologies. Their function is that the ultrasonic sensor 34 utilizes the propagation characteristics of ultrasonic waves in steel. Due to center segregation, the acoustic characteristics such as sound velocity and attenuation inside the steel change. The system transmits and receives ultrasonic waves, and analyzes parameters such as the time and amplitude of the echo signals to detect segregation. Electromagnetic sensor 35, based on the principle of electromagnetic induction, detects changes in the conductivity and permeability of steel due to center segregation, thus indirectly determining center segregation. High-speed data acquisition module 32 can simultaneously and rapidly acquire large amounts of data from both the ultrasonic and electromagnetic sensors. Data processing module 33 processes and analyzes the acquired massive amounts of data in real time. First, the ultrasonic and electromagnetic data undergo preprocessing such as filtering and noise reduction to remove interference signals. Then, using model-based data analysis methods, such as establishing ultrasonic propagation and electromagnetic characteristic models for normal steel structure and different degrees of center segregation, the acquired data is compared and matched with the models to determine the location, range, and degree of center segregation. Visualization module 36 can graphically display the analyzed data.
[0039] In this embodiment, the first hook 21, the first connecting block 23, the second connecting block 25, and the second hook 26 are all arc-shaped. A through groove is provided on one side of the first hook 21, the first connecting block 23, the second connecting block 25, and the second hook 26. The first fixing pin 22 and the second fixing pin 27 are fixedly installed inside the through groove.
[0040] In this embodiment, a guide groove is provided at the bottom of the sliding box 11, and the moving block 14 is slidably installed on the inner side of the guide groove. The moving block 14 is L-shaped. The L-shaped moving block 14 facilitates the installation of the third motor 15, making it less likely to cause obstruction when the third motor 15 drives the lower component to rotate. Moreover, the third motor 15 slides more stably with the sliding box 11 after installation.
[0041] In this embodiment, a threaded hole is provided on one side of the sliding box 11, and the first lead screw 8 meshes with the adjacent threaded hole; in this embodiment, a storage battery is provided at the bottom of the rotating plate 17, and the electric telescopic rod 24 is electrically connected to the storage battery; so that the storage battery can supply power to the electric telescopic rod 24, thereby eliminating the need for an external power cord for the electric telescopic rod 24 and making it less likely for the power cord above the electric telescopic rod 24 to become tangled.
[0042] Specifically, the device controls the first motor 7 to drive the first lead screw 8 to rotate, so that the first lead screw 8 can drive multiple first lead screws 8 to rotate via the pulley 9 and the synchronous belt 10. This allows the first lead screw 8 to drive the sliding box 11 to slide left and right. Meanwhile, the second motor 12 inside the sliding box 11 can drive the moving block 14 to move back and forth via the second lead screw 13, allowing the steel center segregation detection device 5 to move to the center position of the steel. Finally, the device controls the third motor 15 to drive the drive shaft 16 and the rotating plate 17 to rotate. This allows the steel center segregation detection device 5 to rotate circumferentially around the center of the steel, and controls the electric telescopic rod 24 to rise and fall, cooperating with the second connecting block 25 and the second hanging lug 26. This allows the angle of the lower steel center segregation detection device 5 to be adjusted, enabling the device to perform non-destructive and rapid segregation detection on steel of different shapes. The ultrasonic sensor 34 utilizes the propagation characteristics of ultrasonic waves in steel. Since center segregation causes changes in the acoustic properties of the steel, such as sound velocity and attenuation, it detects segregation by emitting and receiving ultrasonic waves and analyzing parameters such as the time and amplitude of the echo signal. The electromagnetic sensor 35 is based on the principle of electromagnetic induction. Center segregation in steel causes changes in its conductivity and permeability. The changes in electromagnetic properties can be detected, thereby indirectly determining center segregation. The high-speed data acquisition module 32 can simultaneously and quickly acquire a large amount of data from the ultrasonic sensor and the electromagnetic sensor. The data processing module 33 can process and analyze the massive amount of data acquired in real time. First, the ultrasonic data and electromagnetic data are preprocessed by filtering and noise reduction to remove interference signals. Then, using model-based data analysis methods, such as establishing ultrasonic propagation models and electromagnetic property models for normal steel structure and different degrees of center segregation, the acquired data is compared and matched with the models to determine the location, range, and degree of center segregation in the steel. The visualization display module 36 can display the analyzed data graphically.
