The purpose of this paper is to review a case study of a successful energy project at the ArcelorMittal Burns Harbor facility involving the addition of five new adjustable frequency drives (AFDs) used to regulate flow of the high-volume water spray system for the runout table (ROT). The paper will outline 1) processes used in justifying new technology updates, 2) mill alignment with the serving electric utility to leverage energy credits, 3) equipment selection and installation and 4) metrics used to demonstrate the project delivered the desired payback.

Adjustable frequency drive offering from Eaton improved reliability and enhanced safety with a small physical footprint. Estimated monthly energy savings up to $45,000, as well as an integrated design contributing to reductions in material costs and timely delivery minimizing plant downtime.
