Abstract
PURPOSE: To obtain a well shaped rolling mill, by setting an adequate roll bending force and controlling an integrated value of the square of the difference between said force and a deflection curve obtained at an actual rolling, to be minimum.
CONSTITUTION: This is a shape controlling method by a sheet rolling mill in a roll mill equipment equipped with a roll bending device. Roll bending force is set in a condition so that an integrated value is to be minimum; the integrated value is obtained by integrating the square of the difference in the axial direction between a desired deflection curve obtained by setting it in the axial direction of working rolls of a rolling mill and a deflection curve obtained at an actual rolling. The roll bending force is controlled according to this set value. Further, for setting the desired deflection curve, working rolls are divided in the axial direction into plural sections.
