Youngstown Sheet And Tube Company
The Youngstown Sheet and Tube Company, based in Youngstown, Ohio, was an American steel manufacturer. Officially, the company was created on November 23, 1900, when Articles of Incorporation of the Youngstown Iron Sheet and Tube Company were filed with the Ohio Secretary of State at Columbus. In 1905 the word "Iron" was dropped from the company name to reflect the company's shift in focus from producing wrought iron products to basic steel products. It acquired the Mark Manufacturing Company in 1923. Youngstown Sheet and Tube remained in business until 1977. A Youngstown resident acquired the name, trademark, and logo in 2014 and opened a small business promoting the economic redevelopment of Youngstown. History In 1888, Youngstown industrialists George D. Wick and James A. Campbell organized the Mahoning Valley Iron Company, with Wick as president. Charles Dayton Arms, Wicks brother in law and also an iron entrepreneur, was brought in as president. Five years later, the two m ...

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Tube (fluid Conveyance)
A tube, or tubing, is a long hollow cylinder used for moving fluids (liquids or gases) or to protect electrical or optical cables and wires. The terms "pipe" and "tube" are almost interchangeable, although minor distinctions exist — generally, a tube has tighter engineering requirements than a pipe. Both pipe and tube imply a level of rigidity and permanence, whereas a hose is usually portable and flexible. A tube and pipe may be specified by standard pipe size designations, ''e.g.'', nominal pipe size, or by nominal outside or inside diameter and/or wall thickness. The actual dimensions of pipe are usually not the nominal dimensions: A 1-inch pipe will not actually measure 1 inch in either outside or inside diameter, whereas many types of tubing are specified by actual inside diameter, outside diameter, or wall thickness. Manufacture There are three classes of manufactured tubing: seamless, as-welded or electric resistant welded (ERW), and drawn-over-mandre ...

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.

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] |
Struthers, Ohio
Struthers is a city in eastern Mahoning County, Ohio, United States, along the Mahoning River. The population was 10,063 at the 2020 census. Located directly southeast of Youngstown, it is a suburb of the Youngstown–Warren metropolitan area. History John Struthers, from Washington County, Pennsylvania, purchased of Poland Township land in 1798 and gave it the name Marbletown. John Struthers owned this land until the War of 1812 came around when he and his family suffered financial ruin. The land was dormant until 1865 when it was purchased by Thomas Struthers. Thomas bought this land to honor his father and he was instrumental in bringing industry and railroads to the town. Eventually, the town would have its name changed to Struthers by popular vote. In 1943, a Jehovah's Witnesses was fined by the city for distributing religious pamphlets door-to-door. The U.S. Supreme Court ruled that this was a violation of the First Amendment in '' Martin v. Struthers''. Influence o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Indiana Harbor (East Chicago)
Indiana Harbor or The Harbor is the portion of East Chicago, Indiana located east of the Indiana Harbor and Ship Canal, as opposed to " East Chicago proper" which is located west of the canal. It contains several distinct neighborhoods, including New Addition, Sunnyside, and North Harbor. The Calumet neighborhood is west of the Canal but sometimes considered distinct from "Indiana Harbor proper". Although Indiana Harbor has never been a separate town, it has often been referred to as one since its establishment in 1901. Historically, Indiana Harbor was more working-class than East Chicago proper, with a population dominated by workers at Inland Steel and related plants. Rivalries between Indiana Harbor and the rest of East Chicago are common. Mexican-American settlement in Indiana Harbor began during the steel strike of 1919. By 1928, Indiana Harbor was home to one of the largest Mexican-American communities in the Midwest. The neighborhood has retained a substantial ...
