Abstract

PURPOSE: To provide an improved control system which enables revision of initially estimated value according to kind of steel through the correction of deviation at the subsequent stands based on deviation from the previously calculated tension value at the stand involved after biting at respective stands, finalyzed by learning of value from a width deviation measuring device on the outgoing side of the final stand.
