Vaclav Smil, in Still the Iron Age, 2016. Direct Reduced Iron. Before moving to a brief review of stateoftheart steelmaking practices, I must devote a few pages to describing the only major practical alternative to BF ironmaking, direct reduced iron (DRI).
Feb 25, 2020· Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal . In some models, Sponge Iron is the category for HBI (Hot Briquette Iron), CDRI (Cold DRI) and HDRI (Hot DRI).
The process of reducing gas to convert iron ore into metallic iron is known as direct reduction. Direct Reduced Iron (DRI) is a manufactured metallic material produced by the reduction (removal of oxygen) of iron oxide at temperatures below the melting point of iron (1536° C or 2797° F).
gas run deep. One immediate beneficiary is directreduced iron, or DRI. Long favored over scrap by steel makers because of its purity, DRI has seen only limited use in the steelmaking process due to historically higher prices. Now, with an inexpensive, reliable supply of natural gas available, steel manufacturers that have access to DRI
The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the noncoking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).

Direct use of iron ore fines without prior agglomeration, such as pelletizing or sintering. Operation with hydrogen as reductant enables reduction with very low CO 2 emission values, and allows the application of low reduction temperatures minimizing sticking tendencies.
Direct Reduced Iron (DRI), also called Sponge Iron or Reduced Iron Powder, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.

Mar 31, 2019· To permanently reduce CO 2 emissions, steelmaker ArcelorMittal has developed a lowemissions technology strategy, which targets not only the use of alternative feedstocks and the conversion of CO 2 emissions, but also the direct avoidance of carbon (Carbon Direct Avoidance, CDA).. This year, the Group intends to launch a new project in the ArcelorMittal plant in Hamburg to
Aug 05, 2020· DRI is high in iron content and low in copper and other undesirable metals, tramp elements, and nitrogen content. It is used to make a broad range of steel productsall types of steel up to and including exposed auto body, extra deep drawing quality, fine wire, special bar quality, forging bar quality, plate and seamless tubes.
In an electric arc furnace, a batch of steel ("heat") may be started by loading scrap or direct reduced iron into the furnace, sometimes with a "hot heel" (molten steel from a previous heat). Gas burners may be used to assist with the melt down of the scrap pile in the furnace. As in basic oxygen steelmaking, fluxes are also added to protect the lining of the vessel and help improve the
Russia has ranked up from the 6th to 5th for the year (2016), and relegated South Korea in the top steelproducing countries list. Domestic steelmakers also reduced steel production, but in a lesser degree than that observed in most other countries. The decrease on home market was offset by a sharp rise in export demand, which was due to the devaluation of the Ruble, and thus, increased the

Modern furnaces will take a charge of iron of up to 350 tons and convert it into steel in less than 40 minutes compared to 10–12 hours in an open hearth furnace. Electric arc furnace steelmaking is the manufacture of steel from scrap or direct reduced iron melted by electric arcs. In an electric arc furnace, a batch of steel ("heat") may be
Direct Reduced Iron (DRI) is an alternative to the blast furnace processes to produce a source of iron units. Greater availability of natural gas has replaced classic coke oven coalbased processes. Several processes are commercially viable today and they use a number of ways to achieve good quality DRI.
