- Q:How are steel billets tested for internal defects?
- Steel billets are tested for internal defects through a variety of non-destructive testing methods. One of the most common methods used is ultrasonic testing (UT). During this process, high-frequency sound waves are transmitted into the billet, and the reflections of these waves are analyzed to detect any internal defects such as cracks, voids, or inclusions. UT can provide accurate and detailed information about the size, location, and nature of the defects. Another method used is magnetic particle inspection (MPI). This technique involves magnetizing the billet and applying iron particles to its surface. If there are any internal defects, the magnetic field will cause these particles to gather around them, making them visible and detectable. Eddy current testing (ECT) is also employed to assess the internal quality of steel billets. It utilizes electromagnetic induction to create eddy currents within the material. Any changes in the electrical conductivity or magnetic permeability caused by internal defects can be detected by analyzing the variations in the induced current. Additionally, radiographic testing (RT) is utilized to inspect the internal structure of steel billets. X-rays or gamma rays are directed towards the billet, and the resulting radiographic image can reveal any internal defects such as voids, cracks, or inclusions. Other methods, such as dye penetrant testing and visual inspection, can also be used to detect superficial and near-surface defects in steel billets. These methods involve applying a liquid or dye to the surface of the billet, which will seep into any cracks or surface irregularities, making them visible under certain lighting conditions. Overall, a combination of these non-destructive testing methods is employed to ensure the quality and integrity of steel billets by effectively detecting any internal defects that could compromise their structural integrity and performance.
