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