Abstract

This paper explains the new run out table (ROT) cooling control system of Wakayama hot strip mill which has been in operation since December 1992. The proposed system has three main features, a precise cooling process model, a cooling profiles stabilizing method and feedforward and feedback control subsystems using the actual temperature of a running strip. The design of the model, method and control loops is outlined and the results of actual strip cooling are presented
