(Page 17 3)
capacity of 45 tons and is serviced by a 12,500 kva transformer.
All of the cable and bus bars connecting each electric furnace to
its transformer has been severed. Although the electrode holders
for each furnace are in place, there are no graphite electrodes
on the site. Located several feet north of furnace X-2 is a
small sheet steel constructed control room for the vacuum
degassing pits on the pouring aisle floor. The aisle is served
by three E.O.T. cranes. A 75-ton crane serves the southern end
of the aisle. A 125-ton and a 25-ton crane serves the charging
floor.
C. Pouring Aisle: The 75'-0" wide x 647'-2" pouring aisle is
located on the eastern side of the building. It extends 75'-0"
farther south than the stock house aisle and 112'-0" farther
north than the stock house and charging aisles. The aisle makes
up the ground floor of the eastern bay. Located below the
pouring spout of each furnace on the western side of the aisle is
a wide gauge track laid out on a east-west axis between 10'-0 M
high splasher walls. The track carried a transfer car which
positioned slag pots below the furnace on its western side. Laid
out on a north-south axis and located near the southern wall of
the aisle on its western side is a 14 f -0" wide x 46'-0" long x
18'-0" deep ladle repair pit capable of servicing three ladles at
a time. Two ladle stands, one located between furnaces X-3 and
X-4 and one located just north of furnace X-5, also exist on the
western side of the aisle. Finally, the western side of the
aisle contains three vacuum degassing casting pits. The northern
most pit, located 40'-o" south of the northern wall of the
aisle, is 17'-0" wide x 45 , -0" long x 24'-5" deep. A 25 , -0" wide
x 85*-0" long x 24 f -5" deep vacuum degassing pit is located 37'-
0" south of the northern most pit. The third vacuum degassing
pit is located 17'-0" north of the ladle repair pit. It is 18'-
0" wide x 25'-0" long x 24'-5" deep.
Running for nearly the entire length of the eastern side of
the aisle is a 7*-9" high steel framed teeming platform. A
narrow gauge track, set upon the floor alongside the platform,
runs through the building. The teeming platform extends into the
lean-to.
A 34'-0" wide x 56*-0" long x 10'-0" high bag house is
located between the eastern outside wall of the electric furnace
building at its southern end and the western outside wall at the
northern end of the steel conditioning building on an
approximately 30'-0" high steel framed platform. It has a gable
roof and continuous ventilator.
Original construction date of building: 1943.
Construction of 3 2 5'-0" extension to southern end of
charging aisle: 1957.
