Technological Control systems assuring the control functions which are responsible for strip quality:
o AGC, including controls such as: feedback, feed-forward, mass flow, adaptive gain setup, AGC control mode selection,
o HGC, including controls such as: position and force measurement, position/force bump-less control, gain compensation roll force and gain compensation cylinder position, cylinder balancing speed, solenoid settings, safety operation, roll gap zeroing, roll gap adjustment, quick opening, etc.
o Pass schedule and coil data handling. Data for AGC, in all passes:
Predicted roll force and roll gap
Orders used for specific coil
Current Pass number
o Data logging and quality supervision.
o AFC, automatic flatness control with work roll bending and cooling controls.
o AEC, automatic elongation control.
