The project involved installation of a replacement furnace transformer (with
an additional 8MVA capacity), replacement Electric Arc Furnace shell (with an
additional 2 tonne melting capacity), and associated technology in the form of
a Chemical Energy System (for the injection of oxygen and carbon into the
furnace, and natural gas firing) - all within a three-week period in 2007.
However, an untimely fault with the existing transformer meant work had to be
completed in stages over a two-year period around the plant's busy production
schedule, with the final stage being completed in January 2008.
Innovative thinking by Brian Perry Civil, a key participant to the project,
meant the project team could replace the furnace foundations prior to the plant
shutting down for a short time over the 2007 Christmas period, allowing the
furnace itself to be replaced right on schedule.
