Founded in 1830 as a small plant for smelting iron, Tannehill expanded during the Civil War into a large battery of three blast furnaces capable of producing 22 tons of pig iron daily for Confederate military needs. The ironworks, along with a dozen other such facilities in Alabama, were badly damaged in the closing months of the Civil War.
How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of …
Iron ore, coke, and flux are fed into the blast furnace and heated. The coke reduces the iron oxide in the ore to metallic iron, and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled, and marketed as pig iron; the rest flows into basic oxygen furnaces, where it is converted into steel.
In 1853-54 the Forest City Iron Works erected a rolling mill on the lakeshore at Wason (East 38th) St., producing the first "saleable manufactured iron" (boiler plate) in May 1855. That year, the Railroad Iron Mill Co., established by Albert J. Smith in partnership with others, erected a plant in the same location to reroll worn rails.
