A programmed computer control system provides online predictive roll force gauge control and screwdown offset gauge control for a tandem hot steel strip mill. A gauge control program calculates corrective screwdown movement including that predictively required at each gauge-controlled stand for optimum or near optimum gain correction of roll force error on the basis of online detected roll force and screwdown position values at that stand and on the basis of a mill spring constant which is predetermined for that stand and a workpiece plasticity value which is automatically determined from roll force and workpiece entry and delivery gauges at that stand. The control system operates the mill screwdowns in accordance with the program calculations.
