Abstract
A programmed computer control system provides an on-line roll force gauge control for a multiple stand tandem hot metal strip rolling mill. A gauge control program calculates the workpiece strip delivery gauge error from at least one stand of the rolling mill and from this gauge error determines a required roll opening correction to remove this gauge error. The gauge control program then determines in relation to the magnitude of the delivery gauge error and related roll opening correction for the same one stand that this delivery gauge error is to be corrected by adjustment of the roll opening of that same one stand or is to be fed forward in the direction of the workpiece strip movement for correction in a succeeding stand of the rolling mill by adjustment of the roll opening of the succeeding stand. The roll opening correction is effective to adjust the latter stand operation for a time interval related to the movement of the workpiece strip increment from the stand where the gauge error is measured to the following correction stand of the rolling mill, assuming the latter stands are adjacent stands of the rolling mill.
