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
Advanced signal processing algorithms allow the controls to estimate coating thickness during order transitions within one coating gauge scan.
The resulting control actions minimise the generation of out-of-spec material and the minimised coating standard deviation allows for zinc savings.
The combined effort of IAS and Nucor engineers resulted in a system which easily exceeded coating performance guarantees.
Further process improvements are anticipated as the new automation system is included in the Millcare continuous improvement and support contract already in place for their two cold mills.
