Cleveland Rolling Mills
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 R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Most steel mills ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuyahoga River
The Cuyahoga River ( , or ) 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, most famously on June 22, 1969, helping to spur the American environmental movement. 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". Etymology The name ''Cuyahoga'' is believed to mean "crooked river" from the Mohawk name ''Cayagaga'', although the Mohawk were never in the region alongside European settlers, so this explanation is questionable. Children in the area are usually taught that it comes from a Seneca word for "jawbone". This explan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cleveland Railroad History
Cleveland has been and continues to be deeply rooted in railroad history. History Early history Cleveland railroading began in the mid-1800's, when the predecessors of the New York Central and Nickel Plate Road (New York, Chicago, & St. Louis) built two major lines along Lake Erie that handled major traffic per day, and had major yards on them at this point. The line that became part of the New York Central, now CSX east of Cleveland, was originally the Cleveland, Painesville and Ashtabula Railroad. This later became part of the Lake Shore and Michigan Southern Railway (LS&MS), and later the NYC. This is the origination of the Amtrak train name, "The Lake Shore Limited", that still operates through Cleveland in the middle of the night. The Nickel Plate Road, (NYC&St.L), aka NKP, now Norfolk Southern, was later acquired by the Van Sweringen brothers, Oris P. and Mantis J., from the NYC. NKP's line bridged over the NYC's line in the western part of Cleveland, and the NYC line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Workforce
The workforce or labour force is a concept referring to the Pooling (resource management), pool of human beings either in employment or in unemployment. It is generally used to describe those working for a single types of companies, company or Industry (economics), industry, but can also apply to a geographic region like a city, state, or country. Within a company, its value can be labelled as its "Workforce in Place". The workforce of a country includes both the employed and the unemployed (labour force). Formal and informal Formal labour is any sort of employment that is structured and paid in a formal way.Seager, Joni. 2008. The Penguin Atlas of Women in the World. 4th ed. New York: Penguin Books. Part 5 Unlike the informal sector of the economy, formal labour within a country contributes to that country's gross national product. Informal labour is labour that falls short of being a formal arrangement in law or in practice. It can be paid or unpaid and it is always unstruct ...

Pig Iron
Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained 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 constituents of dross, which makes it brittle and not useful directly as a material except for limited applications. 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 cause only insignificant problems considering the ease of casting and handling them.

Trade Union
A trade union (labor union in American English), often simply referred to as a union, is an organization of workers intent on "maintaining or improving the conditions of their employment", ch. I such as attaining better wages and benefits (such as holiday, health care, and retirement), improving working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting the integrity of their trade through the increased bargaining power wielded by solidarity among workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The delegate staff of the trade union representation in the workforce are usually made up of workplace volunteers who are often appointed by members in democratic elections. The trade union, through an elected leadership and bargaining committee, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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 Decarburization, 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 (metallurgy), 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 discover ...

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] |
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] |
