- The surface condition of steel billets is typically checked through visual inspection and various non-destructive testing methods. Visual inspection involves thoroughly examining the surface of the billets for any visible defects such as cracks, pits, dents, or scratches. This is usually done by trained inspectors who have a keen eye for detecting surface imperfections. In addition to visual inspection, various non-destructive testing techniques are employed to assess the surface condition of steel billets. These techniques include magnetic particle testing, liquid penetrant testing, ultrasonic testing, and eddy current testing. Magnetic particle testing involves applying a magnetic field to the billet's surface and then applying fine iron particles. If there are any surface defects, such as cracks or inclusions, the magnetic particles will be attracted to these areas and form visible indications. Liquid penetrant testing involves applying a liquid dye to the surface of the billet. The dye penetrates any surface defects, and after a certain period of time, excess dye is removed, and a developer is applied. The developer draws out the dye from any surface defects, making them visible and easy to detect. Ultrasonic testing utilizes high-frequency sound waves to detect surface and subsurface defects. A transducer is used to generate sound waves that penetrate the billet's surface. If there are any defects, such as cracks or voids, the sound waves will reflect back, and by analyzing the reflected waves, any surface or subsurface flaws can be identified. Eddy current testing involves passing an alternating current through a coil placed near the billet's surface. Any surface defects or variations in the material's conductivity will cause changes in the current flow, which can be detected and analyzed to determine the surface condition. These non-destructive testing methods provide accurate and reliable information about the surface condition of steel billets, helping to ensure their quality and integrity before further processing or usage.
