Cleveland Rolling Mill
The Cleveland Rolling Mill Company was a rolling steel mill in Cleveland, Ohio. It existed as an independent entity from 1863 to 1899. Origins The company stemmed from developments initiated in 1857, when John and David I. Jones, along with Henry Chisholm, established a rolling mill at Newburgh, incorporated as ''Chisholm, Jones & Company'', to reroll worn rails. In 1858, Andros B. Stone (brother of Amasa Stone) bought into the firm, which became the ''Stone, Chisholm & Jones Company'', and produced iron rails. The first blast furnace in Cleveland was built by the firm in 1861. In November 1863, an investment from Stone led to the expansion and reorganization of the company, which then became the Cleveland Rolling Mill Company. In 1868 the company installed a pair of Bessemer converters, and started using them to produce steel. During the 1870s, various types of wire products were produced at the mill. In 1881 the company built Central Furnaces plant, near the Cuyahoga Rive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rolling (metalworking)
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes... Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails.

Cuyahoga River
The Cuyahoga River (see ) is a river located in Northeast Ohio that bisects the City of Cleveland and feeds into Lake Erie. As Cleveland emerged as a major manufacturing center, the river became heavily affected by industrial pollution, so much so that it caught fire at least 14 times. When it did so on June 22, 1969, news coverage of the event helped to spur the American environmental movement. For many Americans, the Cuyahoga's burning helped connect urban decay with the environmental crisis at the time in many American cities. Since then, the river has been extensively cleaned up through the efforts of Cleveland's city government and the Ohio Environmental Protection Agency (OEPA). In 2019, the American Rivers conservation association named the Cuyahoga " River of the Year" in honor of "50 years of environmental resurgence". In 2025 the river between the Gorge Dam and the mouth was designated a National Water Trail, a type of National Recreation Trail. Etymology The ...

Workforce
In macroeconomics, the workforce or labour force is the sum of people either working (i.e., the employed) or looking for work (i.e., the unemployed): \text = \text + \text Those neither working in the marketplace nor looking for work are out of the labour force. The sum of the labour force and out of the labour force results in the noninstitutional civilian population, that is, the number of people who (1) work (i.e., the employed), (2) can work but don't, although they are looking for a job (i.e., the unemployed), or (3) can work but don't, and are not looking for a job (i.e., out of the labour force). Stated otherwise, the noninstitutional civilian population is the total population minus people who cannot or choose not to work (children, retirees, soldiers, and incarcerated people). The noninstitutional civilian population is the number of people potentially available for civilian employment. \begin \text &= \text + \text \\ & ...

Pig Iron
Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace. Pig iron has a high carbon content, typically 3.8–4.7%, along with silica and other dross, which makes it brittle and not useful directly as a material except for limited applications. Etymology The traditional shape of the molds used for pig iron ingots is a branching structure formed in sand, with many individual ingots at right angles to a central channel or "runner", resembling a litter of piglets being nursed by a sow. When the metal had cooled and hardened, the smaller ingots (the "pigs") were simply broken from the runner (the "sow"), hence the name "pig iron". As pig iron is intended for remelting, the uneven size of the ingots and the inclusion of small amounts of sand are insignificant issues when compared to the ease of casting and handling. History The Chinese were already making pig ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Trade Union
A trade union (British English) or labor union (American English), often simply referred to as a union, is an organization of workers whose purpose is to maintain or improve the conditions of their employment, such as attaining better wages and Employee benefits, benefits, improving Work (human activity), working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting and increasing the bargaining power of workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The union representatives in the workforce are usually made up of workplace volunteers who are often appointed by members through internal democratic elections. The trade union, through an elected leadership and bargaining committee, bargains with the employer on behalf of its members, known as t ...

Bessemer Process
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 steelmaking, removal of impurities and undesired elements, primarily excess carbon contained in the pig iron by oxidation with air being blown through the molten iron. Oxidation of the excess carbon also raises the temperature of the iron mass and keeps it molten. Virtually all the pig iron carbon is removed by the converter and so carbon must be added at the end of the process to create steel, 0.25% carbon content is a typical value for low carbon steel which is used in construction and other low-stress applications. 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 (inventor), William Kelly though the claim is con ...

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. Integrated mill An integrated steel mill has all the functions for primary steel production: * iron making (conversion of ore to liquid iron), * steel maki ...

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 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 (sometimes oxygen enriched) air 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 flue gases exiting from the top. 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 reverberatory furnaces) are naturally aspirated, usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
