Abstract

PURPOSE: To imrpove accuracy in plate thickness to a remarkable extent and reduce off-gauge rate, by deriving a condition for minimizing the integration value of square of deviation in plate thickness at the outlet side of a rolling mill, and controlling the rolling force by the use of deviation in plate thickness at the outlet side and its differentiation signal onthe basis of said condition.
