This includes checking for cracks, surface oxidation, or any other visible abnormalities that could affect the dimensions. This visual inspection is often conducted by trained personnel who have an eye for detail and can identify even the smallest imperfections. After the visual inspection, the billets undergo dimensional measurement using various tools and instruments. One commonly used tool is a caliper, which is used to measure the length, width, and height of the billet. The measurements are compared against the specified dimensions to ensure they fall within the acceptable range. Any deviations beyond the tolerance limit are flagged for further investigation. In addition to calipers, other tools such as micrometers, height gauges, and coordinate measuring machines (CMM) may also be used to measure specific dimensions or features of the billet. These instruments provide more accurate and precise measurements, especially for critical dimensions that require a higher level of precision. Furthermore, non-destructive testing techniques are employed to assess the internal quality and dimensional accuracy of the billets. Ultrasonic testing, for instance, uses high-frequency sound waves to detect any internal defects or inconsistencies that may affect the dimensions. This method can identify hidden flaws such as voids, inclusions, or discontinuities, providing a comprehensive assessment of the billet's dimensional accuracy. Overall, steel billets are inspected for dimensional accuracy through a combination of visual inspections, dimensional measurements using various tools, and non-destructive testing techniques. By conducting these inspections, manufacturers ensure that the billets meet the required specifications, leading to high-quality final products.
