2. Understanding Automatic Gauge Control (AGC): Structure, Parameters, Performance

Automatic Gauge Control is an integrated control system applied to the cold rolling mill to continuously monitor and adjust strip thickness, ensuring superior product consistency. The advanced hydraulic automatic gauge control leverages closed-loop feedback—hydraulic cylinders actuate the mill rolls in microseconds—to correct thickness deviations.
