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.

Despite the harsh winter weather the demolition of RG Steel’s former Mingo Junction site in Ohio continues.
Blast furnace No. 3 was already dismantled in 2004. The remaining furnace No.5 five came down recently too.
The mill was idled in 2009 and still waits for a new investor to restart the electric arc furnace and the rolling mill.

Demolition Started

Warren Ohio Steel Mill

Demolition started at the  former RG Steel plant in Warren,OH that was purchased by the  Hilco company in May. This deal required to market the hot mill for three months before beginning to raze the plant. Those three months expired at the end of August.
Founded in 1912 as the Trumbull Steel Co., the mill has a long history in steel production. In 1928, the company merged with Republic Iron and Steel Co. and, two years later, was renamed Republic Steel Corp.  Another merger changed its name to LTV Steel Co. when it combined with J&L Steel Corp. in 1984.  The company became Warren Consolidated Industries, Inc. in 1988.
WCI Steel employed 2,600 people, and had an annual steel capacity of 1.5 million tons. In 2008 WCI was taken over by the Russian steel company Severstal.
Three years later Severstal sold the plant to RG Steel who filed bancruptcy in 2012.
The Warren Blast Furnace once was the largest worldwide.

Carnegie Steel Ohio Works
The Carnegie Steel Ohio works on the banks of the Mahoning River around 1910.
This mill became part of U.S. Steel later and was closed in 1979.
Starting with the “Black Monday” in September 1977, the closure of Youngstown Sheet And Tube, the once thriving valley of steel was gutted within just one decade.
A recommendable book telling the story of this decline is John Russo’s “Steeltown U.S.A. – Work And Memory In Youngstown” published by the University Press Of Kansas.
