HAER No. PA-115<br />
(Page 17 3)<br />
capacity of 45 tons and is serviced by a 12,500 kva transformer.<br />
All of the cable and bus bars connecting each electric furnace to<br />
its transformer has been severed. Although the electrode holders<br />
for each furnace are in place, there are no graphite electrodes<br />
on the site. Located several feet north of furnace X-2 is a<br />
small sheet steel constructed control room for the vacuum<br />
degassing pits on the pouring aisle floor. The aisle is served<br />
by three E.O.T. cranes. A 75-ton crane serves the southern end<br />
of the aisle. A 125-ton and a 25-ton crane serves the charging<br />
floor.<br />
C. Pouring Aisle: The 75'-0" wide x 647'-2" pouring aisle is<br />
located on the eastern side of the building. It extends 75'-0"<br />
farther south than the stock house aisle and 112'-0" farther<br />
north than the stock house and charging aisles. The aisle makes<br />
up the ground floor of the eastern bay. Located below the<br />
pouring spout of each furnace on the western side of the aisle is<br />
a wide gauge track laid out on a east-west axis between 10'-0 M<br />
high splasher walls. The track carried a transfer car which<br />
positioned slag pots below the furnace on its western side. Laid<br />
out on a north-south axis and located near the southern wall of<br />
the aisle on its western side is a 14 f -0" wide x 46'-0" long x<br />
18'-0" deep ladle repair pit capable of servicing three ladles at<br />
a time. Two ladle stands, one located between furnaces X-3 and<br />
X-4 and one located just north of furnace X-5, also exist on the<br />
western side of the aisle. Finally, the western side of the<br />
aisle contains three vacuum degassing casting pits. The northern<br />
most pit, located 40'-o" south of the northern wall of the<br />
aisle, is 17'-0" wide x 45 , -0" long x 24'-5" deep. A 25 , -0" wide<br />
x 85*-0" long x 24 f -5" deep vacuum degassing pit is located 37'-<br />
0" south of the northern most pit. The third vacuum degassing<br />
pit is located 17'-0" north of the ladle repair pit. It is 18'-<br />
0" wide x 25'-0" long x 24'-5" deep.<br />
Running for nearly the entire length of the eastern side of<br />
the aisle is a 7*-9" high steel framed teeming platform. A<br />
narrow gauge track, set upon the floor alongside the platform,<br />
runs through the building. The teeming platform extends into the<br />
lean-to.<br />
A 34'-0" wide x 56*-0" long x 10'-0" high bag house is<br />
located between the eastern outside wall of the electric furnace<br />
building at its southern end and the western outside wall at the<br />
northern end of the steel conditioning building on an<br />
approximately 30'-0" high steel framed platform. It has a gable<br />
roof and continuous ventilator.<br />
Original construction date of building: 1943.<br />
Construction of 3 2 5'-0" extension to southern end of<br />
charging aisle: 1957.
