All furnace components were
pre-assembled off-site in as large a segment as
possible. The tilt platform was shipped to ICM in
eight (8) segments and assembled off-site by ICM.
Total weight was 180,000# when installed in one
piece.
By sub-assembling the furnace components,
ICM was able to install the complete furnace, in 34
days, after
the foundations were complete. The largest component
weighed nearly 300,000#.
All furnace foundations were
pre-fabricated off-site using plate forms and
internal ties. Foundation forms were rigged into
place in two sections complete with all reinforcing.
The allowed form work to progress concurrent with
demolition from the completion of the old furnace
foundations to the placing of the 585 cubic yard new
arc furnace foundation in 3 days.
