Abstract: According to the technical character of the cross-cutting process, the whole production line was divided to different tracking zones, and then the tracking task was further divided to two levels. After finalizing the overall scheme, design thought and data flow of the track function for the whole cross-cutting line, the binary and hexadecimal material status description methods were employed to manage the material tracking process. Based on this theory, an applicable material tracking system for cross-cutting process was designed, and the general program flow was described. Setting parameters is gradually sent, which solving the problem that two steel rolls can’t be online at the same time. If no defect detectors are employed and the same technical flow is used with a certain factory, the annual output is predicted to increase 11% and the productivity is improved in indirectly. The long-time industrial application shows that this tracking system is reliable and accurate, and the problem of material information loses never happens, thus keeping the production line goes stably.

Key words: cross-cutting, tracking, tracking level, tracking zones, tracking system
