DESCRIPTION
I. Twenty-Two Inch Bar Mill fNo. 5 Milll:
A. Bloom Yard: The 66'-8" wide x 209' long bloom yard is laid
out on a north-south axis and is located approximately 160*
northeast of the electric furnace building. A steel-framed
overhead craneway running the length of the bloom yard supports a
15-ton E.O.T. crane. Billets which were rolled at the primary
mill were stored in the bloom yard prior to being rolled into
bars. Construction date: 1906.
B. Pre-Heating Furnace Building: Laid out on a north-south
axis, the one-story, 71 f -10" wide x 128* long preheating furnace
building is adjacent to the bloom yard. The riveted steel-
framed, corrugated metal clad building was built upon a concrete
foundation by the American Bridge Company. Its gable roof and
monitor are supported by riveted Fink trusses. A 15-ton E.O.T.
crane rests on top of a craneway spanning the length of the
building.
Located inside of the building at its southern end is a
Loftus Continuous Preheat Furnace. The furnace, which operated
on mixed fuel and was capable of heating billets to 1500° F, has
a 18* wide x 39' long hearth. Billets entered the southern end
of the furnace and were discharged from its northern end onto a
cable driven flat transfer car on standard gauge rails. Two
large motor driven fans, located near the western wall of the
building, provided combustion air to the furnace. Waste gas from
the furnace was conducted through a large brick flue stack
located just outside of the western wall of the building.
Construction date: ca. 1940.
C. Batch Furnace Building: The one-story, 82' wide x 176*
long batch furnace building is laid out on a north-south axis.
