Missouri S&T Using Grant to Improve EAF Steelmaking

Written by Laura Miller

A research team at the Missouri University of Science and Technology will be using a $2 million government grant to improve the operating efficiency of electric-arc furnace (EAF) steelmaking.

The Missouri S&T research team is being led by Dr. Ronald O’Malley, the F. Kenneth Iverson Endowed Chair of Steelmaking Technologies and director of the Kent D. Peaslee Steel Manufacturing Research Center at the university.

“We are working toward implementing a next-generation dynamic control system for the EAF so we can optimize EAF operating efficiency under changing input conditions using new sensor systems,” O’Malley explained.

“In basic terms, the fiber optic system will provide a whole new set of tools for EAF optimization,” O’Malley said. “We will be able to better examine the condition of the EAF and the impact of operating variables on the process in real time to provide feedback to the operator and improve energy efficiency, operating cost, and yield.”

This $2 million grant from the US Department of Energy is part of a larger three-part project. The first two phases were funded by another $2 million and a third phase will utilize over $1 million.

US Steel’s Big River Steel in Osceola, Ark., and Commercial Metals Co.’s facility in Birmingham, Ala., are the two partner steel plants in which new sensor and control module technology developed via grant will be installed.

Additional companies participating in the Missouri S&T research include Nucor, Gerdau, Linde, and CIX, as well as Arizona State University.
