Edgar Thomson Steel Works
The Edgar Thomson Steel Works is a steel mill in the Pittsburgh area communities of Braddock and North Braddock, Pennsylvania, United States. It has been active since 1875. It is currently owned by U.S. Steel and is known as Mon Valley Works – Edgar Thomson Plant on its official website. History The mill occupies the historic site of Braddock's Field, on the banks of the Monongahela River east of Pittsburgh. On July 9, 1755, in the Battle of the Monongahela, French and Indian forces from Fort Duquesne defeated the expedition of British General Edward Braddock, who himself was mortally wounded. Braddock's Field was also the site of a rally of rebellious militiamen and farmers during the Whiskey Rebellion, prior to a massive march on the town of Pittsburgh on August 1, 1794."The Planting of Civilization in Western Pennsylvania, Buck, Solon J. The site is on the banks of the Monongahela, which provides cost-effective, riverine transportation of coke, iron and finished steel pr ...

Steel Mill
A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap. History Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes. In the late 19th and early 20th centuries the world's largest steel mill was the Barrow Hematite Steel Company steelworks located in Barrow-in-Furness, United Kingdom. Today, the world's largest steel mill is in Gwangyang, South Korea. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). The first geologist to distinguish dolomite rock from limestone was Belsazar Hacquet in 1778. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edgar Thomson Steel Works, Braddock Avenue, And Turtle Creek
Edgar is a commonly used English given name, from an Anglo-Saxon name ''Eadgar'' (composed of '' ead'' "rich, prosperous" and ''gar'' "spear"). Like most Anglo-Saxon names, it fell out of use by the later medieval period; it was, however, revived in the 18th century, and was popularised by its use for a character in Sir Walter Scott's ''The Bride of Lammermoor'' (1819).

Monastery Coke Works
A monastery is a building or complex of buildings comprising the domestic quarters and workplaces of monastics, monks or nuns, whether living in communities or alone (hermits). A monastery generally includes a place reserved for prayer which may be a chapel, church, or temple, and may also serve as an oratory, or in the case of communities anything from a single building housing only one senior and two or three junior monks or nuns, to vast complexes and estates housing tens or hundreds. A monastery complex typically comprises a number of buildings which include a church, dormitory, cloister, refectory, library, balneary and infirmary, and outlying granges. Depending on the location, the monastic order and the occupation of its inhabitants, the complex may also include a wide range of buildings that facilitate self-sufficiency and service to the community. These may include a hospice, a school, and a range of agricultural and manufacturing buildings such as a barn, a forge, o ...

Lucy Furnaces
Lucy Furnace was a pair of blast furnaces in Pittsburgh, Pennsylvania, on the Allegheny River in Lawrenceville. The furnaces were part of the Carnegie Steel Company, with the first furnace erected in 1871 by brothers Andrew and Thomas M. Carnegie, Andrew Kloman and Henry Phipps Jr. This furnace was the first one built new by the Carnegies. In 1877 a second furnace, Lucy No. 2, was built at the same site. Lucy was named after co-owner Thomas M. Carnegie's wife. History Operation The furnace entered blast in summer 1872, at the same time as the Isabella Furnace. Over the decades that they operated, the two furnaces developed a fierce rivalry. Prior to their construction, blast furnaces in the United States did not exceed about 50 tons of iron yield per day, and the prevailing attitude of operators was to follow "rule of thumb" methods and not to attempt anything beyond the rated capacity. Lucy and Isabella began an era of scientific refinement of the process, of relentless experime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries. Coke may also be formed naturally by geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116.

Steel Business
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnegie Brothers And Company
Carnegie Brothers & Company, Ltd. was created by the consolidation of the steel businesses owned by Andrew Carnegie in the early 1880s. Those steel and coke works that were consolidated were: *Sciota Ore Mines *Union Iron Mills *Edgar Thomson Steel Works *Lucy Furnaces *Monastery Coke Works *Larimer Coke Works The merging of these separate business operations into one resulted in the newly formed company owning an interest of nearly $5 million. At the time, Andrew Carnegie owned over half of it. Henry Clay Frick began to supply Carnegie Brothers and Company with coal and coke that was required to operate the steel mills. This relationship progressed with the result in Frick being the major supplier of coke to the new company. Thomas Carnegie, Andrew Carnegie's brother died in 1886 and in 1889 Frick began to manage a portion of the company. Frick also bought company shares. Frick advanced and was promoted to chairman of the company. After his promotions Frick worked with Carnegie t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
