CONTINUOUS ROLLING SYSTEM

WIPO Patent Application WO/2022/102138

A1

This continuous rolling system matches the actual rolling load ratio between all of stands during continuous rolling to a target rolling load ratio. The continuous rolling system tracks a tracking point set on a rolling subject material, which is continuously rolled. The continuous rolling system outputs a rolling gap operational value to an i-th stand when the tracking point reaches the i-th stand, the rolling gap operational value being for making a difference between a value obtained by correcting a target sheet thickness value for the i-th stand with a target sheet thickness correction value for the i-th stand and a value obtained by correcting an actual sheet thickness re-calculation value of the i-th stand with a gap correction value for the i-th stand, to be zero. This gap correction value is a correction value for making a difference between a lead end gap error when the lead end of the rolling subject material reaches the i-th stand and a non-lead end gap error when portions other than the lead end of the rolling subject material reach the i-th stand, to be zero.
