Abstract
PURPOSE:To keep the shape and thickness of a rolled material constant along the longitude of a material to be rolled, by controlling the bending force given to a rolling roll and the position of a screw correspondingly to variations of the rolling load along the longitude of a material to be rolled. CONSTITUTION:The screw position S, the rolling load F and the bending force FB are inputted to an arithmetic unit 28 which then operates the thickness deviation DELTAh and shape deviation DELTAlambda according to a lock-on command. An arithmetic unit 30 operates the necessary adjustments DELTAS and DELTAFB respectively for the screw position and the bending force, correspondingly to the thickness deviation DELTAh and shape deviation DELTAlambda outputted by the arithmetic unit 28. A screw position controller 19 receives a screw position command S' given by an adder 32 as a sum of the screw position adjustment DELTAS and the present screw position S, and then drives a screw 16 for adjusting its position. Similarly, a bending force controller 26 receives a bending force command FB' given by an adder 34 as a sum of the bending force adjustment DELTAFB and the present bending force FB, and then adjusts the bending force.
