Direct reduction processes can be divided roughly into two categories: gas-based and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.) in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
New Zealand Steel steel complex, fed by direct reduction rotary furnaces (SL/RN process) [1] (capacity 650,000 t/year). [2] 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.
In an integrated steel mill, iron ore is reduced to metallic iron. In the US, this is done in blast furnaces and since 2014 again using direct reduced iron furnaces in Nucor's plant in Louisiana as well as another DRI plant (producing a compactified version of DRI called hot briquetted iron, or HBI) in Texas by Voestalpine. Some of the iron ...
California Steel reopened part of the Fontana plant to process imported steel slabs into finished products such as rolled steel, while the manufacturing equipment for producing raw steel remained idle. [2] At its founding, California Steel operated on about 400 acres of the Fontana site, leaving 1,400 acres idle, and employed 700 people, less ...
Cleveland-Cliffs announced Monday its Middletown Works steel production complex is in the running to receive up to $500 million in federal funding to build three new plants to reduce carbon emissions.
The steelmaker's CEO David Burritt told WSJ the nearly $3 billion Nippon had pledged to invest in U.S. Steel's older mills was crucial to remain competitive and maintain workers' jobs. "We wouldn ...
The Corex Process is a smelting reduction process created by Primetals Technologies as a more environmentally friendly alternative to the blast furnace. [1] Presently, the majority of steel production is through the blast furnace which has to rely on coking coal [2] and requires a sinter plant in order to prepare the iron ore for reduction. [3]
California's only remaining nuclear power plant plans to use artificial intelligence tools to help it comply with new licensing requirements to keep the decades-old facility running. Atomic Canyon ...
