Zinc coating mass control systems for
Indiana
Steel Dynamics has placed an order with Industrial Automation Services (IAS) to design, supply and commission three zinc coating mass control systems for hot-dip galvanizing lines
Two systems will be delivered to the Butler Indiana plant and the third to the Jeffersonville plant Engineering for the three systems will be executed in parallel, with commissioning of the Butler systems occurring first

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
For control of the zinc coating, IAS will install the system, which utilises a proven physics-based coating mass model to generate accurate references and control the knife to strip distances and stripping gas pressure.
During order transitions, advanced signal processing algorithms enable the controls to estimate coating thickness during order transitions within one coating gauge scan.
Resulting control actions minimise the generation of out-of-spec material and the minimised coating standard deviation allows for zinc savings and a typical return on investment within a few months.
The open architecture control system incorporates the IAS easy to maintain graphical programming interface, and takes advantage of the considerable IAS process know-how and local support.
The new control system will operate in concert with existing Sentek coating gauges to provide improved strip coating performance.
IAS will execute engineering design, project management, installation assistance, commissioning and operator/maintenance training from the IAS offices in Pittsburgh in Pennsylvania and Newcastle in New South Wales.
