U.S. STEEL DUQUESNE WORKS
HAER No. PA-115
(Page 220)
Located in the basement of the building are a series of
fans. The fans were designed to circulate air through vents
leading to the ground floor in an effort to keep dust out of the
building.
The ground floor of the building contains the motors and
motor-generator sets which powered the machinery and other
equipment that was affiliated with the 46" x 110" mill and the
36" x 78" mill. The 5000 hp motor which powered the 46" mill,
and the two 3000 hp motors that powered the 3 6" mill, have been
removed. All electrical equipment was manufactured by the
General Electric Company.
Construction date: 1959.
E. North Motor Room: Laid out on a north-south axis, the 240*
long x 45' wide north motor room is a sheet metal clad lean-to
off of the eastern wall of the primary mill building in line with
the 21" continuous billet mill. Approximately 50 f high, the
steel-framed building was constructed by the American Bridge
Company on a concrete foundation. It consists of a ground floor
and basement. Warren trusses support the building's slanted
roof. A craneway spanning the width of the building extends its
entire length, and supports a 50-ton E.O.T.crane.
Located in the basement of the building is a Bowser forced
oil lubricating system for the billet mill. An accumulator is
also located in the basement. It was used to keep the rolls in
contact with their respective screw down mechanisms. Four
cooling water pumps for the billet mill are also located in the
basement.
The ground floor of the building contains the motors and
motor generator sets which powered the machinery and other
equipment that was affiliated with the 21" continuous billet
mill. This equipment is completely intact. All electrical
equipment was manufactured by the Elliot Company.
Construction date: 19 59.
F. Scrap and Scale Yard: Laid out on a north-south axis, the
1720 f long x 70' wide scrap and scale yard is adjacent to the
western wall of the mill section of the primary mill building.
The corrugated metal clad, steel-framed building was built on a
concrete foundation by the American Bridge Company. It is
approximately 70' high to the underside of the truss. In order
to provide access to the primary mill and shipping buildings, the
scrap and scale yard has no eastern or western walls. Its gable
roof and monitor are supported by riveted Fink trusses. A large
portion of the roof at the middle of the building has been
removed. A craneway spans the width and runs the entire length
