  1. The Context: High-Speed Production vs. Legacy Finishing In modern metallurgy, rolling speeds are pushing the boundaries of physical possibility. However, as high-speed rebar exits the mill, a persistent bottleneck often emerges at the finishing area: Identification and Tagging. While the rolling stands operate with millisecond precision, the final step of applying a physical identity to a steel bundle has remained—until recently—a manual, labor-intensive process. This discrepancy creates a "speed limit" for the entire facility. 2. The Engineering Challenge: Why Manual Intervention Fails Field observations in high-capacity mills reveal three critical failure points for manual tagging: Thermal Radiation Hazards: Finished rebar bundles typically reach the tagging station at temperatures between 200°C and 300°C . Expecting personnel to maintain accuracy while working in proximity to this heat is unrealistic and leads to high turnover and safety risks. The Traceability Gap: ...
