McLouth Steel
McLouth Steel is a former integrated steel company. The company was once the ninth-largest steelmaker in the United States. The company was composed of three locations: the first in Detroit, Michigan, the second (and largest) in Trenton, Michigan, and the third in Gibraltar, Michigan. The Detroit and Trenton plants have been demolished, while the Gibraltar plant has been restarted by Ferrolux. Detroit Complex This complex was built in 1934 by Donald B. McLouth, a Detroit scrap dealer, as a small conversion mill on Livernois Avenue. General Motors desired additional options for steel, providing partial financing for this facility. In its later years, the plant was revamped to produce only stainless steel, eventually being purchased in 1981 by Jones and Laughlin Steel Company. The Detroit mill initially consisted of a small reversing hot rolling strip mill with a slab heating furnace. The original hot strip mill was known as the "Coffee Grinder" from the sounds the mill would make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Argon Oxygen Decarburization
Argon oxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminum. After initial melting the metal is then transferred to an AOD vessel where it will be subjected to three steps of refining; decarburization, reduction, and desulfurization. The AOD process was invented in 1954 by the Lindé Division of The Union Carbide Corporation (which became known as Praxair Praxair, Inc. was an American worldwide industrial gases company. Founded in 1907, Praxair was the largest industrial gases company in North and South America, and the third-largest worldwide by revenue.

Detroit Edison
DTE Electric Company (formerly The Detroit Edison Company) was founded in 1886. DTE Electric's power generation portfolio includes renewable energy, but is primarily generated by fossil fuels. In 2021, 67.32% of electricity generated by DTE came from coal, gas, and oil. The regional average fossil fuel mix was 62.84%. As of 2021, DTE's emission levels of Carbon Dioxide, Sulfur Dioxide, Nitrogen Oxides, and High-Level nuclear waste are higher than regional averages. History Detroit Edison was part of a large holding company called North American Edison Company. North American's stock had once been one of the twelve component stocks of the May 1896 original Dow Jones Industrial Average.Jeremy J.

Rimmed Steel
Deoxidized steel (Also known as killed steel) is steel that has some or all of the oxygen removed from the melt during the steelmaking process. Liquid steels contain dissolved oxygen after their conversion from molten iron, but the solubility of oxygen in steel decreases with cooling. As steel cools, excess oxygen can cause blowholes or precipitate FeO. Therefore, several strategies have been developed for ''deoxidation''. This may be accomplished by adding metallic deoxidizing agents to the melt either before or after it is tapped, or by vacuum treatment, in which carbon dissolved in the steel is the deoxidizer. Types There are four types, ranging from fully deoxidized to slightly deoxidized: ''killed'', ''semi-killed'', ''rimmed'', and ''capped''. Note that none of the various types are better than the other as each is useful in its own regard.. Killed steel Killed steel is steel that has been completely deoxidized by the addition of an agent before casting such that there is ...

Induction Heating
Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an induction coil that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold, silver, aluminum, or carbide. An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor called eddy currents. The eddy currents flow through the resistance of the material, and heat it by Joule heating. In ferromagnetic and ferrimagnetic materials, such as iron, heat also is generated by magnetic hysteresis losses. The frequency of the electric current used for induction heating depends on the object size, material type, coupling (between the work coil and th ...

Arnold Spielberg
Arnold Meyer Spielberg (February 6, 1917 – August 25, 2020) was an American electrical engineer instrumental in contributions "to real-time data acquisition and recording that significantly contributed to the definition of modern feedback and control processes". For General Electric he designed, with his colleague Charles Propster, the GE-225 in 1959. He cited the first computer-controlled "point of sale" cash register as his greatest contribution. His children include filmmaker Steven Spielberg, and screenwriter Anne Spielberg. Early life and career Arnold Spielberg was born in Cincinnati on February 6, 1917. He was of Jewish descent. His mother, Rebecca (née Chechick), was born in Sudylkiv, Ukraine; his father, Samuel, was born in Kamianets-Podilskyi, Ukraine. They later immigrated to the United States, meeting and eventually marrying in Cincinnati. From the age of nine, he began building radios. He scrounged parts from garbage cans to assemble his first crystal rece ... [...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 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 Ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basic Oxygen Process
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 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel Rolling Holdings
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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
