Magnetic particle inspection is another widely used method. In this process, the billets are magnetized, and iron particles are applied to the surface. Any surface defects disrupt the magnetic field, causing the iron particles to gather around the defect, making them clearly visible upon inspection. This technique is particularly effective for detecting defects such as surface cracks. Ultrasonic testing is also commonly employed for inspecting steel billets. High-frequency sound waves are transmitted through the material, and any surface defects or internal flaws cause reflections or echoes. These reflections are detected and analyzed, providing information about the size, location, and type of defect present. Additionally, eddy current testing can be used to inspect steel billets for surface defects. This method involves passing an alternating current through a probe that is placed near the surface of the billet. Any defects or variations in the material's conductivity cause changes in the eddy currents, which can be detected and analyzed to identify surface defects. Overall, steel billets undergo meticulous inspection using a combination of visual, dye penetrant, magnetic particle, ultrasonic, and eddy current testing methods to ensure that any surface defects are identified and addressed, guaranteeing the quality and reliability of the final product.
