Superior Ships Components for EAF Revamp at North Star Bluescope
Mar. 5, 2010 Superior Machine Co. of S.C., Inc. has completed and shipped the major components for an upcoming revamp of North Star BlueScope Steel, LLC’s (NSBSS) electric arc furnace (EAF).
Superior’s field service crew is in the process of reassembling the tilt platform, bottom shell (hearth), and upper shell onsite at NSBSS, Delta, Ohio, that will be installed during an outage planned for this spring.
As part of NSBSS’s efforts to both lower operating costs and reduce energy usage, it contracted Superior to design, manufacture, and install new furnace components.
Superior’s mandate from NSBSS is to increase the furnace volume and simplify the design of the bottom shell. Pre-contract studies indicated that by increasing furnace volume (both hot heel and slag volume allowance), NSBSS could lower its power consumption and decrease tap-to-tap times. The simplified bottom-shell design is expected to decrease maintenance outage durations.
Superior Machine Co. of S.C., Inc. is a privately held company with facilities throughout the U.S. Superior serves the steel and aggregate industries with engineering, fabrication, machining, and field services.
