WEBDec 1, 2022 · Metso Outotec introduced the DRI (direct reduced iron) Smelting Furnace to substitute blast furnaces used in iron and steelmaking. The furnace was developed to tolerate highslag volumes, which are problematic for a conventional electricarc furnace (EAF). When a conventional EAF is used to melt hydrogenbased DRI, gangue content .
WEBOther Asia, other Western World, and Central and Latin America will see the largest growth in iron ore pellet use for DRI or HBI. Global iron ore consumption for steelmaking could grow from 850 million tonnes at the end of the twentieth century to more than billion tonnes over the first quarter of the twentyfirst century.
WEBJan 2, 2024 · Therefore, DRI is a generic term used for metallized products through reduction of iron ore in solid state (granules and pellets) in direct reduction reactors. It consists mainly of metallic iron, residual iron oxides (which do not were fully reduced in the reactor) and typical minor compounds such as silica, alumina, calcium.
WEBApr 20, 2015 · Direct reduction of iron ore pellets (DRI) with and without biomass was studied using hydrogen as the reducing agent.

WEBMay 2, 2022 · The objective of the test was to assess the ability to replace the use of natural gas with green hydrogen in the iron ore reduction process. ... Operations consist of recycling and scrap processing sites, a direct reduced iron plant, two steel mills, three rolling mills and two wire facilities. The group has an annual production capacity of ...
WEBMay 5, 2023 · The iron ore producer sees the steel industry moving through three stages, where operational efficiency is first targeted, including iron ore and energy optimization, before new technologies excluding green hydrogen are introduced in the blast furnace, and later a move to 100% green DRI production.
WEBFeb 15, 2024 · The global annual production of steel is approximately 2 billion tons, accounting for 8 % of the world's energy demand and 7 % of carbon dioxide (CO 2) emissions in the energy direct reduced iron (DRI) reduces CO 2 emissions by 38 % compared with traditional blast furnace–basic oxygen furnace (BF .
WEBJun 30, 2021 · Direct reduced iron (DRI), obtained by this process, is a highpurity ironcontaining raw material which can be used to smelt highpurity steel and special steel [6], [7]. Because this process uses coal (especially lowrank coal) or biomass instead of coke and coldpressed pellets instead of sintering ore, it has become a new highquality, low ...
WEBDirectreduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ...
WEBIron ore is first converted to direct reduced iron (DRI) before being charged into the ESF. Together, the DRIESF equipment can replace the blast furnace, eliminating the need for metallurgical coal. Estimates show that reductions of more than 80 per cent in CO2 emission intensity are potentially achievable processing Pilbara iron ores through ...
WEBOct 1, 2018 · The solid product, called direct reduced iron (DRI) or reduced sponge iron, is cooled in the lower part of the furnace, down to approximately 50 °C, prior to being discharged.
