A zinc coating mass control system uses a proven physics-based coating mass model to generate accurate references and control knife to strip distances and stripping gas pressure.

ArcelorMittal, Indiana Harbor, East Chicago, USA, has placed an order with Industrial Automation Services (IAS) to design, supply and commission a zinc coating mass control system (Achieve Coating Control) for its No2 hot dip galvanizing line The order includes new, complete Knife Control System is also included

Achieva Coating Control utilizes a proven physics-based coating mass model to generate accurate references and control knife to strip distances and stripping gas pressure.

During order transitions, advanced signal processing algorithms enable the controls to estimate coating thickness within one coating gauge scan.

The resulting control actions minimize the generation of out-of-spec material and the minimized coating standard deviation allows for zinc savings and a typical return on investment of a few months.

The replacement Air Knife Control System will provide much faster and more accurate responses for dynamic positioning of the Knives.

Coating measurement will be via existing Sentek Coating thickness gauge.

The open architecture control system incorporates IAS's easy to maintain graphical programming interface, and takes advantage of IAS's considerable process know-how and local support.

Engineering design, project management, installation assistance, commissioning and operator/maintenance training will be executed from IAS's offices in Pittsburgh, Pennsylvania, USA, and Newcastle, New South Wales, Australia.
