ABSTRACT:
A gauge and tension control system for a tandem mill comprises a delivered strip thickness deviation calculating unit for detecting output strip thickness at each of rolling stands, a tension calculating unit for arithmetically determining interstand tensions between two adjacent rolling stands on the basis of armature currents of drive motors and rolling loads at every rolling stand, a memory unit supplied with the output from the delivered strip thickness deviation calculating unit and detecting rolling speed values to thereby produce input strip thicknesses at every rolling stand, an optimal control unit for arithmetically determining optimal speed control quantity and press-down control quantity on the basis of the outputs from the delivered strip thickness deviation calculating unit, the tension calculating unit, the memory unit and a rolling schedule, a speed controller for controlling the speeds of the roll drive motors in dependence on the speed control quantities and a press-down controller for controlling the screw-down position of the rolling stands in dependence on the associated press-down control quantity.
