Use of Direct Reduced Iron (DRI) in the Electric Arc Furnace (EAF) for Steelmaking; Shipping and handling of DRI. Being a highly reduced material, DRI has a tendency to re-oxidise, an exothermic reaction. Thus, without appropriate precautions being taken in its handling, transport and storage, there is a risk of self-heating and fires.
This presentation reviews the different DR processes used to produce Direct Reduced Iron (DRI), providing an analysis on the quality requirements of iron-bearing ores for use in these processes ...
Direct reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains elemental carbon (produced from natural gas or coal) and/or hydrogen.When hydrogen is used as the reducing gas no carbon dioxide is produced. Many ores are suitable for direct reduction.

The industrial development program of any country, by and large, is based on its natural resources. Currently the majority of the world's steel is produced through either one of the two main routes: i) the integrated Blast Furnace – Basic Oxygen Furnace (BF – BOF) route or ii) the Direct Reduced Iron - Electric Arc Furnace (DRI - EAF) route.
The first industrial application of direct reduced iron (DRI) production was Wiberg-Soderfors' DRI shaft furnace process. The history of development and implementation of various gas-based direct reduction processes was studied. The strength and weakness of this processes were evaluated. It was shown that the economics of the direct reduction ...
With the successful production of direct reduced iron with the gas-based HYL direct reduction process, studies were begun for the design of the first commercial plant with a daily capacity of 230 tons of DRI. The first industrial scale direct reduction plant was put into operation on December 5, 1957. The Hylsa Monterrey 1-M plant, a fixed-bed ...
1.1 Direct Reduced Iron Direct reduced iron is produced by the reduction of iron ore by carbon monoxide and hydrogen, as illustrated in simplified form in the equations below: Fe 2 O 3 + 3CO → 2Fe + 3CO 2 Fe 2 O 3 + 3H 2 → 2Fe + 3H 2 O There are several processes for direct reduction of iron ore, principally gas-based shaft
Direct Reduced Iron (DRI) has become an ever increasing, important source of raw material in the production of steel. DRI is produced by the reduction of iron oxide to metallic iron. This process occurs without melting. A reducing gas …
In addition, direct reduced iron has a well-defined chemical composition when compared with steel scrap and has efficient melting properties in the electric arc furnace. Consequently, there is a great increase in the demand for direct reduced iron in electric arc steel making. These attractive features have led to an increase in worldwide ...
The MIDREX MEGAMOD Direct Reduced Iron facility is by far the most advanced plant to produce simultaneous both high quality cold (CDRI) & hot direct reduction iron (HDRI).
