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.
This process has been adopted by three plants: 'Dunswart Iron & Steel Works' in South Africa in 1973, 'Sunflag Iron and Steel' in 1989, and 'Goldstar Steel & Alloy' in India in 1993. Although the industrial application is now well established, the process has not had the impact of its predecessor.
ArcelorMittal's (MT) upcoming hydrogen DRI steel plant in Hamburg, the country's pioneering first-of-its-kind, has been offered financial help of Euro 55 million by the German Federal Government.
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid 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.
ArcelorMittal (MT) gets backing from Belgium and Flanders governments for a Euro 1.1-billion DRI plant project in Gent, which will be a significant effort toward achieving carbon neutrality by 2050.
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]
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 ...
