U.S. STEEL DUQUESNE WORKS
HAER No. PA-115
(Page 61)
10'-0" high control room. The center of the furnace is located
35'-0" from the building's northern wall and 33'-0" from the its
western wall.
Laid out linearly on a north-south axis on the eastern side
of the furnace is a clay gun, manufactured by the William Bailey
Company of Pittsburgh, PA, and an air drill, manufactured by the
Woodings Industrial Corporation of Mars, PA. A Sheppard/Niles
10-ton crane rests on the cast house craneway. The control room
contains a snort wheel, control switches for the furnace tuyeres,
a signal box from blow engine house number two, and gauges
pertaining to the cooling water system, hot blast temperature and
hot blast pressure. Located at each corner of the cast house is
a manually operated lever and pulley system which is connected to
the bleeder stacks at the top of the furnace.
The cast house's iron runners extend from the iron notch on
the eastern side of the furnace. They consist of an
approximately 4'-6" wide x 2 l -0" deep x 23'-3 1/2" long slightly
sloped iron trough which leads to a series of 2'-9" wide x l'-6"
deep slightly sloped iron runners travelling eastward. Located
approximately 15*-0" below the terminus of the cast house iron
runners along the eastern side of the building is a set of
standard gauge railroad tracks where "submarine" ladle cars were
spotted in order to receive the molten iron while the furnace was
being tapped. A series of 2 f -8 1/2" wide x l'-7" deep slightly
sloped slag runners extend from the "monkey" at the northern side
of the furnace. Travelling in a north by northeast direction,
the slag runners emptied out into 400 cubic foot capacity slag
ladles which were located on rail cars set upon standard gauge
tracks approximately 20'-0" below the northern end cast house
floor.
Original construction date: 1896.
Rebuilt: 1920.
Construction of iron and slag runners: 1970.
Installation of crane: 1924.
Installation of clay gun and air drill: 1962.
D. Remains of Cast House Number Four: Laid out on a east-west
axis, the remains of a cast house number four consist of its
brick walls, floor, control room, and partial steel framing
surrounding the remains of blast furnace number four. Supported
by a concrete foundation, the 70'-0" wide x 78'-3" wide x 30'-0"
high remains encase the building's steel frame. The
approximately 8'-0" wide x 30'-0" long control room is located
along the inside northern wall of the cast house remains. Also
extending from the inside northern wall is an approximately 20'-
0" high x 30'-0" wide craneway running in a east-west direction.
The center of the furnace remains is located 35'-0" from the
