The construction of the Duquesne Steel
Works marked an important event in the
movement toward integrated steel
producing ventures in the Monongahela
Valley of western Pennsylvania.
Constructed after the Edgar Thomson
Works (1875) , and the Homestead Works
(1884), the Duquesne Works was the site
of numerous technological innovations
significant in the history of the
American steel industry. The mill was
the first to employ the "direct process"
by which ingots were rolled directly
from the soaking pits without being
reheated. Under Carnegie Steel a new
blast furnace plant was constructed with
the industry's first fully mechanized
material handling system, a innovation
which came to be called the "Duquesne
Revolution." For most of its history,
Duquesne was a primary producer of semi-
finished steel products. In the midst
of a declining regional industrial
system in the 1960s and 1970s, the mill
was shut-down in 1984.
