The furnace was constructed circa 1847 by George W. Bryan, who named the furnace "fanny" for his wife. . Unlike earlier bloomery furnaces that produced wrought iron, the Valley Furnace was a blast furnace that produced pig iron using a bellows to induce a forced draft, using charcoal as a fuel. Ore was provided from surface mines that exploited ...
Two blast furnaces have been preserved, including outer frames, furnaces and Cowper stoves. A protective paint coating minimizes the rusting effects on the blast furnaces. Blast furnace 6 is accessible to the public as part of guided tours. A colorful light installation illuminates the entire area at nighttime. [8] [9] Sulzbach-Rosenberg, Bavaria
With a single blast furnace and three basic oxygen process furnaces, [17] amongst other various mills and production facilities, the plant produces 2.4 million tons of raw steel per annum [17] and 640,000 tons of seamless tubular and sheet products, mainly for purchase by the booming oil industry.
The movement away from charcoal in US iron smelting began in 1827, when a puddling furnace in Phoenixville, Pennsylvania started using anthracite coal. Blast furnaces continued to use only charcoal until about 1840, when coke from coal started replacing charcoal as the fuel and reducing agent. [5]
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide. The blast furnace operates as a countercurrent exchange process whereas a bloomery does not.
While still using 100 ovens, Leetonia Coal & Iron would process 250 tons of coal into coke per day. However, in 1873, the company was bought out and renamed "The Cherry Valley Iron and Coal Company", who expanded operations and eventually had over 200 coke ovens and 4 blast furnaces; processing much more coal than ever before.
Carrie Furnace is a former blast furnace located along the Monongahela River in the Pittsburgh area industrial town of Swissvale, Pennsylvania, and it had formed a part of the Homestead Steel Works. The Carrie Furnaces were built in 1884 and they operated until 1982. During its peak, the site produced 1,000 to 1,250 tons of iron per day. [3]
By 1796 Wilkinson had erected the first blast furnace on the site, east of the Hall, 884 tons of iron being produced in this first year. [1] This initial furnace ("No. 1") worked continuously until 1894 when it was finally 'blown out', and continued in use afterwards as a sand hopper. From 1805 a second furnace was brought into production. [2]
