Final report on Contract No 7210-PR/089, 1 July 1998 to 31 December 2001.

This project has mainly focused on the investigation of the influence of hot-strip cross-sectional profile, camber and other process variables on cold mill processing and quality, as well as the adaptation and adjustment of the set-up and control to the length-dependent hot-strip characteristics and the compensation of disturbances.

The project has significantly enhanced the understanding of the influence of many parameters (such as entry thickness profile, hot-strip camber, roll force) on the cold-rolling processing and the cold-strip quality characteristics. Correlations between these parameters and between them end the quality measures have been established. A working three-head strip camber measurement facility has been installed and commissioned at the entry end of a pickle line.

A new control system has been developed and tested that contributes to the improvement of inter-stand and product flatness. The improvement in flatness performance is greatest at coil transitions, where there is a step change in strip entry profile and roll force. The new control system is excellent groundwork towards an integrated (coordinated) control system for the whole mill considered.
