Added to NRHP. September 13, 1976. Designated PHMC. May 12, 1948 [2] The Warwick Furnace Farms is a historic district that is located in northern Chester County, Pennsylvania, United States that includes the ruins of an early iron furnace that was owned by Anna Rutter Nutt, widow of Samuel Nutt. [3]
Cast iron is more brittle than wrought iron or steel, which required additional fining and then cementation or co-fusion to produce, but for menial activities such as farming it sufficed. By using the blast furnace, it was possible to produce larger quantities of tools such as ploughshares more efficiently than the bloomery.
Bessemer converter, schematic diagram. The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also ...
Iron plantation. Iron plantations were rural localities emergent in the late-18th century and predominant in the early-19th century that specialized in the production of pig iron and bar iron from crude iron ore. [1] Such plantations derive their name from two sources. First, because they were nearly self-sufficient communities despite an ...
Direct reduction processes can be divided roughly into two categories: gas-based and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.) in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt, [1] were made from meteoritic iron-nickel. [2] It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores in ...
Buckeye Steel Castings was a Columbus, Ohio steelmaker best known today for its longtime president, Samuel P. Bush, who was the grandfather of President George H. W. Bush and great-grandfather of President George W. Bush. Buckeye, named for the Ohio Buckeye tree, was founded in Columbus as the Murray-Hayden Foundry, which made iron farm implements.
