IAS to Supply Coating Control for Indiana Harbor Galv Line
Nov. 13, 2007 ArcelorMittal has placed an order with Industrial Automation Services (IAS) to design, supply and commission a zinc coating mass control system for the No. 2 hot dip galvanizing line at its Indiana Harbor facility in East Chicago, Ill. IAS will also supply a new, complete knife control system.
For control of the zinc coating, IAS will install the Achieva Coating Control system, which 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, Achieva’s advanced signal processing algorithms enable the controls to estimate coating thickness within one coating gauge scan. Resulting control actions minimize the generation of out-of-spec material, and minimized coating variations allow 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. An existing Sentek coating thickness gauge will provide the coating measurement.
IAS will execute engineering design, project management, installation assistance, commissioning and operator/maintenance training from its offices in Pittsburgh, Pa., and Newcastle, NSW, Australia.
