Jan 01, 2008· A simplified system boundary diagram, which guides and bounds this study, was created for the stainless-steel cycle and is shown in Fig. 1a.It includes the major processes associated with the production of primary chromium, nickel, and iron, the preparation of scrap, the smelting of stainless steel, and the transportation of nine intermediate products.
Jan 05, 2012· By using direct reduced iron, steel makers can dilute lower grade ores and lower cost ferrous scrap to attain acceptable levels of contamination in the mix. If direct reduced iron pellets are substituted for pelletized ores in blast furnaces, the amount of coke per ton of pig iron would be cut.
May 15, 2018· National waiver for pig iron and direct reduced iron allows the use of products made from non-domestic pig iron and directly reduced iron in SRF-funded projects (discussed later in this presentation) Steel is an alloy that includes at least 50 percent iron, between .02 and 2 percent carbon, and may include other elements

Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 °C (1,470 to 2,190 °F) in the presence of the reducing gas syngas ...
Jun 21, 2018· Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.
Mar 30, 2016· In book: Encyclopedia of Iron, Steel, and Their Alloys (pp.pp 1082-1108) Chapter: i) Direct Reduced Iron: Production; Publisher: CRC Press, Taylor and Francis Group, New York.
Direct reduced iron (DRI) is a comparatively new cargo that has already presented problems when shipped in bulk. With its sponge-like structure, DRI has a very large surface area per unit weight. Consequently, it is chemically reactive and this makes it dangerous to store or ship in bulk.
same processing stream. In particular, the stainless steel slag has been a focus since its application in construction materials has been limited due to the high content of FeO and the environmental concern of heavy metals leaching (e.g., Cr). Along with the iron and steel making, the cement industry is also among the largest industrial CO 2 ...
Solid state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI). Since DRI is produced by removing oxygen from iron ore, its structure is just like sponge with a network of connecting pores.

Dec 14, 2006· Solid-state reduced ore and/or pellets, known as DRI (Direct Reduced Iron), are melted in electric arc furnaces and converted to steel in the same way as scrap metal. During the steelmaking process, the gangue in DRI is removed; the gangue minerals contained in DRI combine with the added lime to form a fluid slag.
Steel Technology Roadmap 11 Chapter 2: Process Development New cokemaking processes are needed to shift the by-produc t compositions to more valuable products. The off-gas from a coke plant could be used to produce direct reduced iron or serve as a feedstock for chemical processes.
