Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed
into more functional shapes and sizes. While they have already been put in the furnace, they still require
a series of shaping and molding procedures such as hot and cold working, milling and cutting before they
are sold in hardware stores, or used for different applications. The unformed billets, however, can be used
in striking currency such as coins and as reserves, similar to gold bars.

- Q: What are the different methods of steel billet surface inspection?
- There are several different methods of steel billet surface inspection that are commonly used in the industry. These methods are designed to detect any defects or imperfections on the surface of the billet, ensuring that only high-quality steel is used in the manufacturing process. 1. Visual inspection: This is the most basic method of surface inspection where trained inspectors visually examine the surface of the billet for any visible defects such as cracks, dents, scratches, or surface irregularities. While it is a simple technique, it is still an important initial step in the inspection process. 2. Magnetic particle inspection: This method involves applying a magnetic field to the billet's surface and then applying iron particles in a liquid suspension. Any surface defects or cracks will cause the iron particles to adhere to the surface, creating a visible indication of the defect. This technique is particularly effective for detecting surface cracks. 3. Eddy current testing: Eddy current testing uses electromagnetic induction to detect surface defects. A probe is passed over the billet's surface, and any changes in electrical conductivity caused by cracks or other defects will generate eddy currents, which can be detected and analyzed. This method is commonly used for detecting surface cracks, but it can also be used to measure the thickness of coatings or detect variations in material properties. 4. Ultrasonic testing: Ultrasonic waves are used to inspect the billet's surface for any defects. A transducer is used to send ultrasonic waves into the material, and any changes in the wave pattern caused by defects on the surface are detected and analyzed. This method is commonly used for detecting surface cracks, but it can also provide information about the internal structure of the billet. 5. Dye penetrant inspection: This method involves applying a colored dye to the billet's surface, which is then removed, leaving only the dye trapped in any defects or cracks. A developer is then applied to make the dye more visible, allowing inspectors to identify and locate any surface defects. This technique is particularly effective for detecting small surface cracks. 6. Laser scanning: Laser scanning uses a laser beam to scan the surface of the billet and create a three-dimensional representation of the surface. This method is useful for detecting surface irregularities, measuring dimensions, and creating digital models for further analysis. Each of these methods has its own advantages and limitations, and they are often used in combination to ensure a thorough inspection of the steel billet's surface. The choice of inspection method depends on factors such as the type of defects being targeted, the size and shape of the billet, and the desired level of accuracy.
