the wall are approximately 5' wide x 50» long x 6" deep. The vat<br />
farthest from the wall is approximately 5' wide x 60 f long x 6 1<br />
deep. After cooling, bars were routinely immersed in the<br />
sulfuric acid solution contained within the vats. This process<br />
made it possible to thoroughly inspect the bars for defects<br />
because it removed surface scale from them. Once identified, the<br />
defects were removed from the bars at one of the conditioning<br />
buildings. Two large sulfuric acid storage tanks are located<br />
near the southeastern corner of the building just outside of its<br />
southern wall.<br />
Two rail heads running in a north-south direction through<br />
the 22" bar mill shipping buildings No. i, 2, and 3, end in the<br />
bar stocking and finishing building. One rail head is located<br />
between the slow cool pits and the pickling vats, the other is<br />
located at the western end of the building.<br />
Construction date: ca. 194 2.<br />
G. Twenty-Two Inch Bar Mill Shipping Building No. 1: Laid out<br />
on an east-west axis, the one story, 65' wide x 480■ long 22" bar<br />
mill shipping building was constructed by the Duquesne Works.<br />
Built on a concrete foundation, the riveted steel-framed building<br />
is adjacent to the north side of the 22" bar stocking and<br />
finishing building. Its north and south ends are open in order<br />
to provide a clear passageway to the bar stocking and finishing<br />
building to its south and to the shipping buildings no. 2 and 3<br />
on its north. The building's gable roof is supported by Fink<br />
trusses. Three 20-ton E.O.T. cranes are on top of a craneway<br />
which spans the width of the building and runs its entire length.<br />
Located inside of the building just north of the eight slow<br />
cooling pits in the bar stocking and finishing building are four<br />
more slow cooling pits. Three of these pits are 6' wide x 42'<br />
long x approximately 4* deep. The other pit is 6' wide x 52*<br />
long x approximately 4* deep. Located just west of the slow<br />
cooling pits next to the hot bed run-out table is a Kron cradle<br />
type floor scale.<br />
Part of a Sutton bar straightening machine is located at the<br />
far western end of the building just east of the rail head. Laid<br />
out on a north-south axis, the straightening machine also<br />
occupies space in the 22" bar shipping building no. 2. It had<br />
the ability to straighten bars from 2 1/2" to 10" in cross-<br />
section x 10' to 50 ! in length at a rate of between 100 to 150<br />
tons per eight hour turn.<br />
Construction date: ca. 1942.<br />
