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