Real-time strip position tracking between rolling mill stands for centerline alignment.
Global Gauge’s Interstand Centerline Deviation System is designed to monitor and control strip position between rolling mill stands. Using advanced vision-based measurement, the system tracks strip movement in real time, identifying deviations from the intended centerline path. The data feeds back to mill operators or directly into AGC loops for proactive alignment control.
High-frame-rate camera images the strip between two consecutive rolling stands.
Software locates both strip edges and computes the centerline position relative to the mill axis.
Real-time deviation values published with mm accuracy at 100+ Hz.
Output to HMI for operator action or directly into AGC for closed-loop alignment.
LineTrack Monitor. Centerline position at every stand from entry to the F7 width gauge, drive side against operator side, with the PLC and operator control traces plotted together.
