- Q: How are steel billets inspected for internal defects?
- Steel billets are inspected for internal defects using various non-destructive testing (NDT) techniques. One common method is ultrasonic testing (UT), where high-frequency sound waves are used to detect defects inside the billet. A transducer sends ultrasonic waves into the billet, and the reflected waves are analyzed to identify any internal flaws. UT is capable of detecting defects such as cracks, voids, inclusions, and other discontinuities. Another method employed is magnetic particle inspection (MPI). This technique is particularly useful for detecting surface and near-surface defects in ferromagnetic materials like steel. A magnetic field is applied to the billet, and iron particles are spread over the surface. If there is a defect, the magnetic field will cause the particles to form visible indications, providing a clear indication of any internal flaws. Liquid penetrant testing (PT) is another widely used method for inspecting steel billets. In this process, a liquid dye is applied to the surface of the billet and allowed to penetrate any surface-breaking defects. After a specified time, excess dye is removed, and a developer is applied. The developer draws out the penetrant from any defects, making them visible under proper lighting conditions. Additionally, radiographic testing (RT) can be employed to detect internal defects in steel billets. This method uses X-rays or gamma rays to capture images of the billet's internal structure. The radiation passes through the billet, and a film or digital detector records the transmitted radiation. Any internal defects will appear as shadows on the image, allowing for their identification. Overall, a combination of these NDT techniques is often used to ensure thorough inspection of steel billets for internal defects. This helps maintain the quality and integrity of the billets, ensuring they meet the required specifications and standards.

Shape defects: Shape defects refer to the deviations from the desired shape of the billet. These can include bowing, twisting, or excessive tapering. Shape defects can be caused by uneven cooling, improper alignment of the rolling mill, or incorrect rolling parameters. 3. Internal defects: Internal defects are defects that are not visible on the surface but can affect the structural integrity of the billet. These defects can include segregation, porosity, and inclusions. Internal defects can be caused by the presence of impurities in the raw material, improper heating or cooling, or inadequate quality control measures. 4. Dimensional defects: Dimensional defects refer to deviations from the desired dimensions of the billet, such as variations in length, width, or thickness. These defects can be caused by improper calibration of the rolling mill, incorrect rolling parameters, or inadequate quality control measures. 5. Metallurgical defects: Metallurgical defects are defects that occur due to improper metallurgical processes during rolling. These defects can include grain size variations, improper grain flow, or undesirable microstructure. Metallurgical defects can be caused by improper temperature control, inadequate alloying, or insufficient heat treatment. It is important for steel billet rolling mills to have proper quality control measures in place to identify and rectify these defects. Regular inspections, testing, and monitoring of the rolling process can help to minimize these defects and ensure the production of high-quality steel billets.
