Saldanha Steel was a South African steel company originally formed as a partnership between Iscor Limited and the Industrial Development Corporation (IDC). [1] Saldanha Steel is now part of ArcelorMittal South Africa, which in turn is part of global steel company ArcelorMittal. The mill was shut down and mothballed in 2020 [2] resulting in the loss of 1500 jobs.
The R6,8bn Saldanha Steel facilities, situated on the Cape west coast roughly 10 km away from Langebaan Lagoon's ecologically sensitive wetlands, has been designed to produce 1.25 million tons of hot-rolled carbon steel coil per year. [3] The mill was commissioned in 1998.
Following the unbundling of Iscor's mining and steel assets, the Industrial Development Corp. has now become a major shareholder of Iscor Ltd.
It is one of the few steel making plants which do not use blast furnaces and coke. The factory comprises the process parts (right to left on image above when scrolled)
Steelmaking is the process of producing steel from iron ore and/or scrap. Steel has been made for millennia, and was commercialized on a massive scale in the 1850s and 1860s, using the Bessemer and Siemens-Martin processes.
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 supplied above atmospheric pressure.
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.
New Zealand Steel Limited is the owner of the Glenbrook Steel Mill, a steel mill located 40 kilometres south of Auckland, in Glenbrook, New Zealand. The mill was constructed in 1968 and began producing steel products in 1969. Currently, the mill produces 650,000 tonnes of steel a year, which is either used domestically or exported. Over 90% of New Zealand's steel requirements are produced at Glenbrook, while the remaining volume is produced by Pacific Steel, a steel recycling facility in Ōtāhuhu, Auckland. The mill is served by the Mission Bush Branch railway line, which was formerly a branch line to Waiuku. Coal and lime trains arrive daily. Steel products are also transported daily. The mill employs 1,150 full-time staff and 200 semi-permanent contractors.
An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc.
An ironworks or iron works is an industrial plant where iron is smelted and where heavy iron and steel products are made. The term is both singular and plural, i.e. the singular of ironworks is ironworks.
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore into iron by a reducing gas which contains elemental carbon and/or hydrogen. When hydrogen is used as the reducing gas no carbon dioxide is produced. Many ores are suitable for direct reduction.
ArcelorMittal South Africa is part of the steel company Arcelor-Mittal. The company was originally Iscor Ltd., a South African parastatal steel company. It was founded in 1928 and was first listed on the JSE Securities Exchange in 1989.
ArcelorMittal Kryvyi Rih is Ukraine's largest integrated steel company, founded in 1934 and located in Kryvyi Rih, in central Ukraine.
Wheeling-Pittsburgh Steel was a steel manufacturer based in Wheeling, West Virginia.
Electrometallurgy is a method in metallurgy that uses electrical energy to produce metals by electrolysis. It is usually the last stage in metal production and is therefore preceded by pyrometallurgical or hydrometallurgical operations. The electrolysis can be done on a molten metal oxide which is used for example to produce aluminium from aluminium oxide via the Hall-Hérault process. Electrolysis can be used as a final refining stage in pyrometallurgical metal production (electrorefining) and it is also used for reduction of a metal from an aqueous metal salt solution produced by hydrometallurgy (electrowinning).
Mobarakeh Steel Company is a private Iranian steel company, located 65 km south west of Esfahan, near the city of Mobarakeh, Esfahan Province, Iran. It is the largest steel maker of MENA region, and one of the largest industrial complexes operating in Iran. It was commissioned after the Iranian Revolution in 1979 and initiated operations during 1993. It underwent major revamping during year 2000, and is scheduled for a second and third revamping in 2009–2010, bringing the total steel output to 7,200,000 metric tons per year. The company owns the successful football club, Sepahan. In, 2022, this company employs over 14,000 people and generates more than 5.5 billion dollars per year. The company is not only a steel producer but also owns a number of other small steel producer, power plants, substations, mines, and a gas field.
The Libyan Iron and Steel Company (Lisco) is one of the largest iron and steelmaking companies operating in North Africa. Based in Misrata, it is subsidized and owned by the Libyan government. Lisco's foundation stone was officially laid on 18 September 1979. In 2004, the online magazine Arab Steel ranked Lisco third among the largest Arab iron and steel companies.
JSW Ispat Steel Ltd (JISL) was an Indian company with operations in iron, steel, mining, energy and infrastructure. It was set up as Nippon Denro Ispat Limited in May 1984 by founding chairman M. L. Mittal. It was listed on the Bombay Stock Exchange and National Stock Exchange of India until 2013 when it was merged with JSW Steel. It was headquartered in Mumbai and employed about 3,000 people.
The Minière et Métallurgique de Rodange (MMR) was a Luxembourgish blast furnace steel producer and mining company originally established in 1872 as the Hauts-Fourneaux de Rodange. From 1905 to 1935 the company was a division of the Ougrée-Marihaye company.
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron (pig iron). The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place. The process does not require the manufacturing of iron ore agglomerates such as pellets and sinter, nor the production of coke, which are necessary for the blast furnace process. Without these steps, the HIsarna process is more energy-efficient and has a lower carbon footprint than traditional ironmaking processes. In 2018 Tata Steel announced it has demonstrated that more than 50% CO2 emission reduction is possible with HIsarna technology, without the need for carbon capture technology.
The Corex Process is a smelting reduction process created by Primetals Technologies as a more environmentally friendly alternative to the blast furnace. Presently, the majority of steel production is through the blast furnace which has to rely on coking coal and requires a sinter plant in order to prepare the iron ore for reduction. Unlike the blast furnace, smelting reduction processes are typical smaller and use coal and oxygen directly to reduce iron ore into a usable product.
In 2022, the U.S. was the third-largest producer of raw steel worldwide, after China and India, and ranked sixth in pig iron production. By November 2024, the industry produced over 74 million net tons annually.
ArcelorMittal Bremen is a steelworks on the banks of the River Weser in Bremen, Germany.
In the iron and 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 pre-reduced iron ore.
