Abstract
PURPOSE: To manufacture the rolled product without necessity of cutting off the rolled material's side edges, by carrying out the rolling work with adjustable draft for changing the roll gap during the shape rolling work, in order to reduce the breadth deviation along the longitude of the rolled material to a specified or less value at the end of the broadside rolling work, hereafter, by applying the finish rolling work including the edging work.
CONSTITUTION: The draft schedule for the rolling work is computed 20; at the same time, the breadth deviation after the final finishing pass is forecasted depending on the forecasting model of the plane shape of the steel sheet; depending on this forecasted value, the thickness change in the final pass of the shape rolling work is computed 22. This thickness change is converted 24 into the change of the draft position of the horizontal roll, and the converted value is displayed by the control unit 28 for the draft position and the rolling speed. Next, under this condition, the necking volume at the tip of the rolled material 14 is detected, and according to said change of the draft position, the rolling work is carried out with the aim thickness and shape at a specified position in the rolling direction. After finishing the broadside rolling work for this rolled material 14, its side edges are subjected to the finishing broadside rolling work including the edging pass; hereby, the rolled product without necessity of cutting off the side edges is manufactured.
