Abstract
PURPOSE: To obtain the rolled strip of superior shape and thickness accuracy by setting the roll screw-down position with consideration being taken for the change component of the mill rigidity coefficient in the optimum intermediate roll position under the next rolling condition based on the actual results of the previous rolling.
CONSTITUTION: The shape parameters A expressing the broadside elongation patterns of the previous rolling material in quartic functions and the position δ of the intermediate roll of that time, the bending pressure Q and screw-down position S of the work rolls and inlet side plate thickness H and outlet side plate thickness h are detected and the model correction coefficient ε is obtained from formula I. The influence coefficient β affecting the A of each parameter is calculated from the rolling results δ, Q of the previous rolling material and the rolling conditions S', H', h' and ε of the next rolling material. By using this β, the δ' which makes A of the next rolling material 0 is obtained from formula I and the mill rigidity coefficient K is calculated from formula II and the required rolling load P from formula III. From this K and P, and roll screw-down position for the next rolling material is determined.
