In the hot rolling process, structural sections like angles and channels are straightened by a machine at the finishing stage and then bundled in a bundling machine. These bars are cut to length using a flying shear and the length of these bars range from 6 to 12 meters. At the end of this process, an operator visually inspects the bars for straightness, marking any defects by painting the tail end of the bar in yellow color. However, not all bars are inspected, which increases the risk of defective products being missed. Additionally, manual inspection poses safety risks, as workers must enter the bar conveying area, which also interrupts production. The accuracy of this process is also inconsistent, as it heavily depends on the operator’s experience. To ensure quality, bars need to be inspected along two axes—both vertical and horizontal—according to the TIS standard, which requires the straightness deviation to be within 0.3% of the product length.
The solution must ensure 100% automated inspection, eliminating human involvement to improve accuracy and safety. The system should have ±1 mm precision and complete inspections within 8 seconds to prevent delays (ideally, without stopping the line).
