Replacement mill control systems
Ormet Aluminum Mill Products has placed further orders with IAS for upgrades to their existing control systems, to install the IAS Windows based IOWorks graphical development/maintenance environment
The setup models include dynamic order change (flying gauge change) technology, normalised reduction algorithms, rollgap models, speed dependent reference trajectories, schedule dependent gains and adaptive learning algorithms to improve transition and body thickness performance and consistency and also reduce system maintenance.
Given the relative inaccessibility of the site, a key feature of the automation is its reliability.
This was achieved by the use of a PC based system for which spare components are easily sourced and which is readily understood by maintenance staff.
The setup models were supplied with the assistance of ABB who supplied the mill Level 1 automation system and design for the Level 2 automation, which was implemented by ARIM.
IAS is also currently upgrading the setup model on the Panzhihua hot finish mill.
