read online, part I, pp. 240; 250-254; 257. (capacity 650,000 t/year).(fr) Adolf Ledebur (trans. Barbary de Langlade revised and annotated by F. Valton), ''Manuel théorique et pratique de la métallurgie du fer, Tome I et Tome II'', t. 2, Librairie polytechnique Baudry et Cie éditeur, 1895 [:fr:Référence:Manuel théorique et pratique de la métallurgie du fer (A.Ledebur), details of editions], pp. 350-352. In the iron and Steel, steel industry, direct reduction is a set of processes for obtaining iron from iron ore, by reducing iron oxides without melting the metal. The resulting product is Direct reduced iron, pre-reduced iron ore. Historically, direct reduction was used to obtain a mix of iron and slag called a bloom in a bloomery. At the beginning of the 20th century, this process was abandoned in favor of the blast furnace, which produces iron in two stages (reduction-melting to produce cast iron, followed by Refining (metallurgy), refining in a Converting (metallurgy), conve ...

Tatara (furnace)
The is a traditional Japanese Metallurgical furnace, furnace used for smelting iron and steel. The word later also came to mean the entire building housing the furnace. The traditional steel in Japan comes from ironsand processed in a special way, called the tatara system.https://www.jsme.or.jp/tsd/ICBTT/conference02/TatsuoINOUE.html "Science of Tatara and Japanese Sword - Traditional Technology viewed from Modern Science" by Tatsuo INOUE Iron ore was used in the first steel manufacturing in Japan. Tatara steelmaking process using ironsand was conducted in the Kibi Province, which later became the base of the Japanese sword#Classification by school, Bizen school of swordsmithing, around the middle of the sixth century, and steelmaking using ironsand is thought to have spread from Kibi to various places in Japan. In western Japan, a low box-shaped furnace different from the Chinese and Korean style was used to refine iron, and in eastern Japan, both a low box-shaped furnace and a ...

Latin America
Latin America is the cultural region of the Americas where Romance languages are predominantly spoken, primarily Spanish language, Spanish and Portuguese language, Portuguese. Latin America is defined according to cultural identity, not geography, and as such it includes countries in both North and South America. Most countries south of the United States tend to be included: Mexico and the countries of Central America, South America and the Caribbean. Commonly, it refers to Hispanic America plus Brazil. Related terms are the narrower Hispanic America, which exclusively refers to Spanish-speaking nations, and the broader Ibero-America, which includes all Iberic countries in the Americas and occasionally European countries like Spain, Portugal and Andorra. Despite being in the same geographical region, English- and Dutch language, Dutch-speaking countries and territories are excluded (Suriname, Guyana, the Falkland Islands, Jamaica, Trinidad and Tobago, Belize, etc.), and French- ...

Natural Gas
Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium. Methane is a colorless and odorless gas, and, after carbon dioxide, is the second-greatest greenhouse gas that contributes to global climate change. Because natural gas is odorless, a commercial odorizer, such as Methanethiol (mercaptan brand), that smells of hydrogen sulfide (rotten eggs) is added to the gas for the ready detection of gas leaks. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) are thermally decomposed under oxygen-free conditions, subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other ...

Adrien Chenot
Adrien C. B. Chenot (born on August 30, 1803; died November 27, 1855) was a French engineer best known for his inventions in metallurgy as well as his research on manufactured gases. He is notably the inventor of one of the first modern methods of direct reduction of iron ore, based on the use of coal reacting with the ore in retorts . He exhibited the first samples of pre-reduced iron ore at the Lisbon Universal Exhibition of 1849, and was awarded the "''Grandes Medailles d'Or''" (Gold Medal of Honour) at the Paris Universal Exposition of 1855. Early life Born in Bar-sur-Aube, he went to school in Nancy then in Paris. In 1820, he entered the Ecole des mines de Paris, and on leaving this school, he was attached to the General Secretariat of the Department of Bridges and Roads. He left this post some time after to operate mines in Auvergne. Career In 1826, Chenot was asked by Auguste de Marmont, Duke of Raguse, to carry out metallurgical studies at Châtillon-sur-Saône, wh ...

Showa Steel Works
The () was a Japanese government-sponsored steel mill that was one of the showpieces of the industrialization program for Manchukuo in the late 1930s. History Shōwa Steel Works began as the ''Anshan Iron & Steel Works'', a subsidiary of the South Manchurian Railway Company in 1918. The city of Anshan in Liaoning was chosen for its proximity to the Takushan iron ore deposits and rail works at Mukden. The company used low grade iron; in 1934 it mined 950,000 tonnes. In 1933, after reorganization and expansion, it was renamed the Shōwa Steel Works. Shōwa Steel produced pig iron and steel, and the steel mill was soon surrounded by a large industrial complex of other factories to produce a variety of metal products. Sumitomo Steel Pipe established a plant to produce steel pipes, and Manchurian Roll Manufacturing Company to produce steel mill rolls. To feed the furnaces, coal mines were established at Fushun, 35 kilometers to the east, which also led to electric power plants, co ...

Electric Arc Furnace
An electric arc furnace (EAF) is a Industrial furnace, furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundry, foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking. Arc furnaces used in research laboratories and by Dentistry, dentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can reach , while laboratory units can exceed . In electric arc furnaces, the material inside the furnace (referred to as a charge) is directly exposed to an electric arc, and the current from the electrode terminals passes through the charge material. Arc furnaces differ from induction furnaces, which use eddy currents to heat the charge. History In the 19th century, a number of people had employed an electric arc to melt iron. Sir Humphry Davy conducted an experimental demonstration in 1810; we ...

Open Hearth Furnace
An open-hearth furnace or open hearth furnace is any of several kinds of industrial Industrial furnace, furnace in which excess carbon and other impurities are burnt out of pig iron to Steelmaking, 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 Embrittlement, embrittle the steel from excessive nitrogen exposure, was easier to control, and permitted the melting and refining of large amounts of scrap, scrap iron and steel. The open-hearth furnace was first developed by German/British engineer Carl Wilhelm Siemens. In 1865, the French engineer Pierre-Émile Martin took out a licence from Siemens and first applied his regenerative furnace for ...
