Duluth Works
The Duluth Works was an industrial steel and cement manufacturing complex located in Duluth, Minnesota, United States, in operation 1915 to 1987. The complex was operated by the United States Steel Corporation. Officially, the plant's purpose was to supply the growing Midwest with steel finished products. Unofficially, they were built as part of a "gentleman's agreement" between U.S. Steel and the State of Minnesota to not impose hefty iron ore taxes on U.S. Steel in exchange for a fully integrated steel plant within Minnesota, whose mines furnished 80% of the ore to U.S. Steel. The combined works of the steel and cement plant were the largest employers in Duluth and the fourth largest industrial complex in Minnesota. Minnesota Steel Company In 1907, U.S. Steel agreed to build an integrated steel plant in the vicinity of Duluth, which was from the largest iron ore source in the United States, the Iron Range. U.S. Steel theorized that by using the Great Lakes, it could haul limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
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 carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Billet
A billet is a living-quarters to which a soldier is assigned to sleep. Historically, a billet was a private dwelling that was required to accept the soldier. Soldiers are generally billeted in barracks or garrisons when not on combat duty, although in some armies soldiers with families are permitted to maintain a home off-post. Used for a building, the term ''billet'' is more commonly used in British English; United States standard terms are ''quarters'', ''barracks'', ''Single (Soldier) Housing'' or ''Family Housing''. British history Originally, a "billet" (from the French) was a note, commonly used in the 18th and early 19th centuries as a "billet of invitation." In this sense, the term was used to denote an order issued to a soldier entitling him to quarters with a certain person. From this meaning, the word billet came to be loosely used of the quarters thus obtained. Repeated petitions against the practice of billeting, starting in the 16th century, culminated in its outla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Duluth
West Duluth refers to an official neighborhood district in the west–central part of Duluth, Minnesota, United States. Grand Avenue, Central Avenue, Cody Street, and Interstate Highway 35 are four of the main routes in West Duluth. Other main routes in West Duluth include 40th Avenue West, 46th Avenue West, and Mike Colalillo Drive. Neighborhoods Seven neighborhoods are located within official West Duluth district boundaries: *Cody * Denfeld * Fairmount * Irving *Oneota * Spirit Valley * Bayview Heights (associated more with Proctor, MN) Geography & Population West Duluth covers an area of , or 13% of the city area, making it the third largest district in the city. Note that, as with many other Duluth neighborhood districts, the area is actually developed to a major extent is considerably smaller than the district figure. This is largely due to the harsh topography (hill) of the area. The 2000 census enumerated 11,431 residents in the district, a 3% change from 1990. 23.8% o ...

Superfund
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The program is administered by the United States Environmental Protection Agency, Environmental Protection Agency (EPA). The program is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as "Superfund" sites. There are 40,000 federal Superfund sites across the country, and approximately 1,300 of those sites have been listed on the National Priorities List (NPL). Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups). The EPA seeks to identify parties responsible for hazardous substances released to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund (a trust ...

Duluth Missabe And Iron Range Railway
The Duluth, Missabe and Iron Range Railway (DM&IR) , informally known as the Missabe Road, was a railroad operating in northern Minnesota and Wisconsin that used to haul iron ore and later taconite to the Great Lakes ports of Duluth and Two Harbors, Minnesota. Control of the railway was acquired on May 10, 2004, by the Canadian National Railway (CN) when it purchased the assets of Great Lakes Transportation. History The DM&IR was formed by the merger in 1937 of the Duluth, Missabe and Northern Railway (DM&N) and the Spirit Lake Transfer Railway. The following year, the Duluth and Iron Range Rail Road (D&IR) and Interstate Transfer Railway were added. All of these had been leased by the DM&N since 1930. The D&IR was formed in 1874 by Charlemagne Tower to haul iron ore from the Minnesota Iron Co. in Tower, Minnesota, to the new Lake Superior port of Two Harbors, Minnesota. On July 31, 1884, the D&IR carried its first ore shipment from the Soudan Mine. In 1887, the D&IR was acqu ... [...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.

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.

Dumping (pricing Policy)
Dumping, in economics, is a kind of injuring pricing, especially in the context of international trade. It occurs when manufacturers export a product to another country at a price below the normal price with an injuring effect. The objective of dumping is to increase market share in a foreign market by driving out competition and thereby create a monopoly situation where the exporter will be able to unilaterally dictate price and quality of the product. Trade treaties might include mechanisms to alleviate problems related to dumping, such as countervailing duty penalties and anti-dumping statutes. Overview A standard technical definition of dumping is the act of charging a lower price for the like product in a foreign market than the normal value of the product, for example the price of the same product in a domestic market of the exporter or in a third country market. This is often referred to as selling at less than "normal value" on the same level of trade in the ordinary cours ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basic Oxygen Furnace
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz-Donawitz steelmaking or the oxygen converter processBrock and Elzinga, p. 50. is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is known as ''basic'' because fluxes of burnt lime or dolomite, which are chemical '' bases'', are added to promote the removal of impurities and protect the lining of the converter. The process was invented in 1948 by Swiss engineer Robert Durrer and commercialized in 1952–1953 by the Austrian steelmaking company VOEST and ÖAMG. The LD converter, named after the Austrian towns Linz and Donawitz (a district of Leoben) is a refined version of the Bessemer converter where blowing of air is replaced with blowing oxygen. It reduced capital cost of the plants and smelting time, and increased labor productivity. Between 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benzole
In the United Kingdom, benzole or benzol is a coal-tar product consisting mainly of benzene and toluene. It was originally used as a 'motor spirit', as was petroleum spirits. Benzole was also blended with petrol and sold as a motor fuel under trade names including "National Benzole Mixture" and "Regent Benzole Mixture". Confusingly, in certain languages, such as German, Hungarian, Ukrainian and Russian the word "benzol" (or benzole) means benzene, and in some of these languages, words pronounced like benzene (e.g. the German word "Benzin") can mean petrol, or gasoline.Collins German Concise Dictionary, 1991, See also * Antiknock agent An antiknock agent is a gasoline additive used to reduce engine knocking and increase the fuel's octane rating by raising the temperature and pressure at which auto-ignition occurs. The mixture known as gasoline or petrol, when used in high compr ... References External links The National Benzole CompanyInsolvent since 8 April 2013 Coal ...
