Abstract

PURPOSE: To enhance an accuracy of AGC by compensating an error of rolling force and to improve a product yield, by adding a measured value of horizontal force, between a roll chock and a housing while rolling, to the thickness control of a gaugemeter method.
CONSTITUTION: An initial roll gap is obtained in the rolling set-up calculation by using the eq.Iin which Ptr is obtained from previous results and learning, and is set in a rolling stand; where h0: sheet thickness at the outlet side of mill, s0: set value of roll gap when material is not yet bitten, M: rigidity factor of a whole rolling mill including rolls and housing, K: constant. Further, during rolling the roll gap is modified by performing the gauge computing based on the eq.Iconcerning the sheet thickness H at the inlet and h0 at the outlet with Ptr from the detected loads of load cells 6W10 computing.
