ABSTRACT
Typically, an automatic plan view control system is employed as an addition to the well-known automatic gauge control systems. Figure 17.22 illustrates a block diagram in which an automatic plan view control system is implemented as part of a hydraulic automatic gauge control system that is based on the gaugemeter principle. The output signal P from the load cell that measures the roll separating force, is divided by the value Ks which represents the mill spring. The resulting signal P/Ks is equal to the mill stretch and is input into the roll gap regulator along with the output signal c0 from the roll gap sensor, the gauge reference hr , and the plan view gauge correction signal t:.he .
