Campbell, Ohio
Campbell (; ) is a city in eastern Mahoning County, Ohio, United States, along the Mahoning River. The population was 7,852 at the 2020 census. Located directly southeast of Youngstown, it is a suburb of the Youngstown–Warren metropolitan area. Campbell was first called East Youngstown and this designation still appears on real estate deeds between 1902 and 1926, when the city was renamed for local industrialist James Campbell, then chairman of the Youngstown Sheet and Tube Company. History In 1902, the Youngstown Iron Sheet and Tube Company established a factory near the Mahoning River in what was then Coitsville Township. A settlement grew around the factory, called East Youngstown, due to its location just southeast from downtown Youngstown. The village was incorporated in 1908, as its population swelled with young immigrants to work in the steel industry. Many immigrants to the village were Greeks. The plant, which would later be known as the Campbell Works, contained f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

Mahoning Valley
The Youngstown–Warren–Boardman, OH–PA Metropolitan Statistical Area, typically known as the Mahoning Valley (and historically the Steel Valley), is a metropolitan area in Northeast Ohio and Western Pennsylvania the United States, with the city of Youngstown, Ohio, at its center. According to the US Census Bureau, the metropolitan statistical area (MSA) includes Mahoning and Trumbull counties in Ohio and Mercer County in Pennsylvania. As of the 2020 census, the region had a population of 541,243, making it the 107th largest metro area in the country. Taking its name from the Mahoning River, the area has a large commuter population that works in Cleveland and Pittsburgh and their metropolitan areas. It is located in the Rust Belt, the former industrial region of the northern United States. The Youngstown–Warren combined statistical area adds the Salem micropolitan area and Columbiana County, Ohio to the region, increasing the total population to 643,120. The You ...

Brier Hill
Brier Hill is a neighborhood in Youngstown, Ohio, that was once viewed as the city's "Little Italy." The neighborhood, which was the site of the city's first Italian settlement, stretches along the western edge of Youngstown's lower north side and encircles St. Anthony's Church, an Italian-American Roman Catholic parish. Each year, at the end of August, the Brier Hill Fest attracts thousands of visitors from Northeast Ohio and Western Pennsylvania. Early history The area encompassing the Brier Hill neighborhood was originally owned by Youngstown industrialist George Tod, who established a farm on the neighborhood's brier-covered hills around 1801. Tod called the agricultural enterprise Brier Hill. This semi-rural area was transformed irrevocably when coal was discovered in the hills in and around Brier Hill. The neighborhood drew thousands of immigrants seeking work in the mines, and Brier Hill became Youngstown's oldest working-class neighborhood. The first iron furnace in the n ...

Bar Stock
Bar stock, also (colloquially) known as blank, slug or billet, is a common form of raw purified metal, used by industry to manufacture metal parts and products. Bar stock is available in a variety of extrusion shapes and lengths. The most common shapes are round (circular cross-section), rectangular, square and hexagonal. A bar is characterised by an "enclosed invariant convex cross-section", meaning that pipes, angle stock and objects with varying diameter are not considered bar stock. Bar stock is commonly processed by a sequence of sawing, turning, milling, drilling and grinding to produce a final product, often vastly different from the original stock. In some cases, the process is partially automated by specialized equipment which feeds the stock into the appropriate processing machine. Process and types Most metal produced by a steel mill or aluminium plant is formed (via rolling or extrusion) into long continuous strips of various size and shape. These strips are cut ...

Strip Mill
The strip mill was a major innovation in steelmaking, with the first being erected at Ashland, Kentucky in 1923. This provided a continuous process, cutting out the need to pass the plates over the rolls and to double them, as in a pack mill. At the end the strip was cut with a guillotine shear or rolled into a coil. Early (hot rolling) strip mills did not produce strip suitable for tinplate, but in 1929 cold rolling began to be used to reduce the gauge further. The first strip mill in the United Kingdom was opened at Ebbw Vale in 1938 with an annual output of 200,000 tons. The strip mill had several advantages over pack mills: * It was cheaper due to having all parts of the process, starting with blast furnace A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper.

Semi-finished Casting Products
Semi-finished casting products are intermediate castings produced in a steel mill that need further processing before being finished goods. There are four types: ''ingots'', ''blooms'', ''billets'', and ''slabs''. Ingot Ingots are large rough castings designed for storage and transportation. The shape usually resembles a rectangle or square with generous fillets. They are tapered, usually with the big-end-down. Bloom In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than . Blooms are usually further processed via rotary piercing, structural shape rolling and profile rolling. Common final products include structural shapes, rails, rods, and seamless pipes. Billet A billet is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bessemer Converter
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 raises the temperature of the iron mass and keeps it molten. Related decarburizing with air processes had been used outside Europe for hundreds of years, but not on an industrial scale. One such process (similar to puddling) was known in the 11th century in East Asia, where the scholar Shen Kuo of that era described its use in the Chinese iron and steel industry. In the 17th century, accounts by European travelers detailed its possible use by the Japanese. The modern process is named after its inventor, the Englishman Henry Bessemer, who took out a patent on the process in 1856. The process was said to be independently discovered in 1851 by the American inventor William Kelly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Hearth Furnace
An open-hearth furnace or open hearth furnace is any of several kinds of industrial furnace in which excess carbon and other impurities are burnt out of pig iron to produce steel. Because steel is difficult to manufacture owing to its high melting point, normal fuels and furnaces were insufficient for mass production of steel, and the open-hearth type of furnace was one of several technologies developed in the nineteenth century to overcome this difficulty. Compared with the Bessemer process, which it displaced, its main advantages were that it did not expose the steel to excessive nitrogen (which would cause the steel to become brittle), was easier to control, and permitted the melting and refining of large amounts of scrap iron and steel. The open-hearth furnace was first developed by German-born engineer Carl Wilhelm Siemens. In 1865, the French engineer Pierre-Émile Martin took out a license from Siemens and first applied his regenerative furnace for making steel. Their pr ...

Blast Furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel ( coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process. In contrast, air furnaces (such as reverbera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Americans
Greek Americans ( el, Ελληνοαμερικανοί ''Ellinoamerikanoí'' ''Ellinoamerikánoi'' ) are Americans of full or partial Greek ancestry. The lowest estimate is that 1.2 million Americans are of Greek descent while the highest estimate suggests over 3 million. 350,000 people older than five spoke Greek at home in 2010. Greek Americans have the highest concentrations in the New York City, Boston, and Chicago regions, but have settled in major metropolitan areas across the United States. In 2000, Tarpon Springs, Florida, was home to the highest per capita representation of Greek Americans in the country (25%). The United States is home to the largest number of Greeks outside of Greece, followed by Cyprus and Australia. History Early history The first Greek known to have been to what is now the United States was Don Doroteo Teodoro, a sailor who landed in Boca Ciega Bay at the Jungle Prada site in present-day St. Petersburg, FL with the Narváez expedition in 152 ...
