In 1965 there were 237 blast furnaces at 72 locations in the U.S. . This series will briefly introduce all of them.
The American Rolling Mill Company (Armco) had it’s main plant in Middletown, Ohio.
Although the plant was built in 1900, a blast furnace was not built there until 1953. Until then, the pig iron was supplied by the nearby Hamilton ironworks.
In 1965 Armco-Middletown operated a 76-oven coke plant built by Wilputte, 1 blast furnace, and 13 open hearth furnaces.
Most steel was finished in Armco’s 80” wide hot strip mill.
