Stakhanov Ferroalloy Plant
Stakhanov Ferroalloy Plant () is the largest (about 50% of all-Ukrainian production) plant for the production of ferrosilicon in Ukraine. The plant is located in the city of Kadiivka (formerly Stakhanov), Luhansk Oblast, Ukraine. It is located on uncontrolled territory. History The decision to start construction was made in 1952. Construction took place during 1959-1962. The plant has eight ferroalloy furnaces with a capacity of about 2,000 tons per month each. The main products are: ferrosilicon, ferromanganese, and ferrosilicon manganese. Most of the company's products (about 75%) were exported from Ukraine. In 2011, SFP reduced the production of ferroalloys by 5.2% compared to 2010 - to 208.3 thousand tons. At the same time, the plant increased the production of ferrosilicon (in terms of 45%) by 6.8% - to 145.3 thousand tons, but reduced the production of silico-manganese - by 24.7% to 63 thousand tons. By the end of 2011, four Cypriot companies: Philex Investments Limited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrous Metallurgy
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores in the region from Greece to India,Riederer, Josef; Wartke, Ralf-B.: "Iron", Cancik, Hubert; Schneider, Helmuth (eds.): Brill's New Pauly, Brill 2009Early Antiquity By I.M. Drakonoff. 1991. University of Chicago Press. . p. 372 and Sub-Saharan Africa. The use of wrought iron (worked iron) was known by the 1st millennium BC, and its spread defined the Iron Age. During the medieval period, smiths in Europe found a way of producing wrought iron from cast iron (in this context known as pig iron) using finery forges. All these processes required charcoal as fuel. By the 4th century BC southern India had started exporting Wootz steel (with a carbon conten ...

South Ossetia
South Ossetia, ka, სამხრეთი ოსეთი, ( , ), officially the Republic of South Ossetia – the State of Alania, is a partially recognised landlocked state in the South Caucasus. It has an officially stated population of just over 56,500 people (2022), who live in an area of , on the south side of the Greater Caucasus mountain range, with 33,000 living in the capital city, Tskhinvali. Only Russia, Venezuela, Nicaragua, Nauru, and Syria recognise South Ossetia as a sovereign state. Although Georgia does not control South Ossetia, the Georgian government and the United Nations consider the territory part of Georgia. Georgia does not recognise the existence of South Ossetia as a political entity, and the territory comprising South Ossetia does not correspond to any Georgian administrative area (although Georgian authorities have set up the Provisional Administration of South Ossetia as a transitional measure leading to the settlement of South Ossetia ...

Stakhanov, Ukraine
Stakhanov (), or Kadiivka () is a city in the Luhansk Oblast (region) of eastern Ukraine occupied by Russia. The city is incorporated as a city of oblast significance. Its population is approximately . Name Before 1937 the city was known as Kadiivka. From 1937 to 1940 the city was named Sergo ( uk, Серго, translit=Serho) in honor of Sergo Ordzhonikidze, and then from 1940 to 1978 the city was again known as Kadiivka. On 15 February 1978 the city was named after the Soviet miner Alexey Stakhanov, who started his career there. Since 2014 the city has been occupied by Russian-backed militia troops as a part of self-proclaimed Luhansk People's Republic (LPR). Although Ukraine does not control the territory of LPR, it is internationally recognized as a part of Ukraine by most member states of the United Nations except Russia. On May 12, 2016, Ukraine's Verkhovna Rada within the process of decommunization changed its legal name back to Kadiivka. History A local newspaper has be ...

Slag
Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further categorized by their precursor and processing conditions (e.g., Blast furnace (BF) slags, air-cooled blast furnace (ACBF) slag, basic oxygen furnace (BOF) slag, and electric arc furnace (EAF) slag) . Due to the large demand for these materials, slag production has also significantly increased throughout the years despite recycling (most notably in the iron and steelmaking industries) and upcycling efforts. The World Steel Association (WSA) estimates that 600 kg of by-products (~90 wt% is slags) are generated per tonne of steel produced. Composition Slag is usually a mixture of metal oxides and sili ...

Anode
An anode is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, an electrode of the device through which conventional current leaves the device. A common mnemonic is ACID, for "anode current into device". The direction of conventional current (the flow of positive charges) in a circuit is opposite to the direction of electron flow, so (negatively charged) electrons flow out the anode of a galvanic cell, into an outside or external circuit connected to the cell. For example, the end of a household battery marked with a "-" (minus) is the anode. In both a galvanic cell and an electrolytic cell, the anode is the electrode at which the oxidation reaction occurs. In a galvanic cell the anode is the wire or plate having excess negative charge as a result of the oxidation reaction. In an electrolytic cell, the anode is the wire or plate upon which excess positive charge is imposed. As a result of this, anion ...

Ferromanganese
Ferromanganese is a ferroalloy with high manganese content (high-carbon ferromanganese can contain as much as 80% Mn by weight). It is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon (usually as coal and coke) in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace. The oxides undergo carbothermal reduction in the furnaces, producing the ferromanganese. Ferromanganese is used as a deoxidizer for steel. A North American standard specification is ASTM A99. The ten grades covered under this specification includes; *Standard ferromanganese *Medium-carbon ferromanganese *Low-carbon ferromanganese A similar material is a pig iron with high content of manganese, is called spiegeleisen, or specular pig iron.

Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the form of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
