- Q: How are steel billets inspected for internal and surface defects?
- Steel billets are inspected for internal and surface defects through a variety of methods to ensure their quality and integrity. For internal defects, one common method is ultrasonic testing (UT), where high-frequency sound waves are transmitted through the billet. Any discontinuities or defects within the billet will cause the sound waves to reflect back to the receiver, indicating the presence of a flaw. UT can detect defects such as cracks, voids, and inclusions within the billet. Another technique used for inspecting internal defects is magnetic particle inspection (MPI). This method involves applying a magnetic field to the billet and then coating it with iron particles. Any internal defects or cracks will disrupt the magnetic field, causing the iron particles to gather at these locations and become visible under proper lighting conditions. When it comes to surface defects, visual inspection is typically the first step. Trained inspectors visually examine the billet for any visible irregularities, such as cracks, pits, scratches, or deformities. They may also use specialized equipment like magnifying glasses or microscopes to ensure a thorough inspection. In addition to visual inspection, surface defects can also be detected using other non-destructive testing techniques. One common method is dye penetrant testing (PT), where a colored liquid dye is applied to the billet's surface. The dye seeps into any surface defects and is later removed, leaving behind a visible indication of the defect. This method is particularly effective in detecting surface cracks or discontinuities. Another technique used for surface defect inspection is eddy current testing (ECT). ECT relies on the principle that a fluctuating magnetic field induces electrical currents in conductive materials like steel. Any surface defects or irregularities will disrupt the induced currents, which can be detected by monitoring changes in the electrical properties of the billet. ECT is commonly used to detect surface cracks, pits, or variations in thickness. Overall, a combination of these inspection methods allows for a comprehensive evaluation of steel billets, ensuring that both internal and surface defects are detected and addressed before the billets are further processed or used in various applications.
