The simplest and most commonly used method is visual inspection, where inspectors visually examine the billet surface for visible defects such as cracks, pits, or irregularities. This method relies on the expertise and experience of the inspector. Magnetic particle inspection involves the use of magnetic fields and particles to detect surface and near-surface defects. By applying a magnetic field and particles to the billet surface, any defects attract particles, making them visible under proper lighting. Liquid penetrant inspection is another method used to detect surface defects. It involves applying a penetrant to the surface, which seeps into defects. After removing excess penetrant, a developer is applied to draw out the penetrant from the defects, making them visible. Ultrasonic inspection uses high-frequency sound waves to detect internal and surface defects. Sound waves are emitted into the billet using a transducer, and the reflected waves are analyzed to identify defects such as cracks, voids, and inclusions. Eddy current inspection is a non-destructive testing method that uses electromagnetic induction to detect surface defects. By moving a probe over the billet surface and passing an alternating current through it, any irregularities or defects disrupt the current flow, which can be detected and analyzed. Each method has its own advantages and limitations, and the choice depends on specific inspection requirements and constraints. Manufacturers utilize these methods to ensure the quality and reliability of steel billets before further processing or use in various applications.
