This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is 'directly reduced' in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces ...

This forms the direct reduced iron (DRI) which is typically composed of 90 to 94% iron. After the DRI exits the shaft furnace, it can be cooled and compressed to briquetted iron for safe storage and transportation. The hot metal can also be taken directly to the electric arc furnace for immediate use. This technology eliminates the need for a coking or sintering plant. (Industrial Technology ...

Ironmaking is the major energy consuming and CO2-emmiting step in steel production. Direct reduction processes are an alternative to the traditional blast furnace because of the use of H2 in the reducing gases which generate less CO2. There are two main technologies for direct reduction of iron, Midrex and Energiron (or Hyl) which together are responsible for 80% of the production of direct ...

In the search for a pure, available iron source, steelmakers are focusing their attention on Directly Reduced Iron (DRI). This material is produced by the reaction of a low gangue iron ore with a hydrocarbonaceous substance. Commercially, DRI is generated in four different reactors: shaft (moving-bed), rotary kiln, fluidized bed, and retort (fixed-bed).

This paper presents recent results of direct reduction investigation of different combination of blends of manganese ore, iron ore and coal at the Department of Ferrous Metallurgy (IEHK) of RWTH Aachen University. A mixture of iron and manganese ore in a ratio of 75/25 is a good raw material for steelmaking of high Mn‐alloyed grades. The experimental studies consisting of reduction of (a ...

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.

DRI is also known as sponge iron, it is a solid-state direct reduction process (Fig. 2.6). Coal, dolomite and iron ore or pellets are fed into one end of a rotary kiln, while sponge iron and char are withdrawn from the other end. Primary and secondary airs are supplied to the kiln to initiate combustion and reaction processes (Choudhury, 2014 ...

Circored® is a two stage fluidized bed process, reducing iron ore fines directly without prior agglomeration, that operates at low reduction temperatures using pure hydrogen as the reducing gas. The hydrogen is produced by means of natural gas reforming, but hydrogen from sources other than a steam reformer, e.g. from water electrolysis, can also be used. The first reduction stage is a ...

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.
