Enhancing Direct Reduced Iron (DRI) for Use in Electric ...
where the DRI coming out of the shaft furnace can be charged hot into the EAF. However, a significant number of steelmaking plants that use DRI receive it at ambient temperature, thus reducing its potential valueinuse. Preheating the DRI presents a way for such operations to increase this valueinuse of DRI before it is charged into the furnace. Air Products' DRI preheating process ...

Potential for CO2 emissions reduction in MIDREX direct ...
shaft furnace.) DRI is fed to EAF to produce steel. As the iron oxide descends through the furnace, the iron oxide is heated and reduced. Reason why MIDREX is less CO2 Emission As Fuel Table shows the CO2 emission rates for combusting methane versus two types of coal. As the table shows, natural gas emits only about onehalf the CO2 per unit of energy as does coal. 9 As Reductant C + O 2 →CO ...

Refractory Systems | Direct Reduction Plants
STEULERKCH supplies the full range of refractories and services for the DRI production process. Upper Part Middle Section In the upper part and the middle section of the shaft furnace the refractory lining is exposed to strong abrasion due to the feed of lump iron ore in that area as well as strong gas circulations caused by the offtake which is placed in the upper part. Due to that ...
TECHNICAL DEVELOPMENTS IN THE MIDDREX PROCESS
shaft furnace. It is a cylindrical, refractorylined vessel and is a key component of the direct reduction process. It is flexible as well as a versatile reactor. It can use natural gas, a syngas from coal, coke oven gas, or exhaust gas from Corex process as the reducing gas. The shaft furnace is designed on the principle of counter flowing gas and solids to maximize reduction efficiency. The ...

· DRI, HBI, Iron ore lumps, pellets, PERED process, Reformer, Shaft furnace, PERED Technology for Direct Reduced Iron Production. PERED technology is also known as 'Persian Reduction' technology. It is the direct reduction technology invented and patented by 'Mines and Metals Engineering ' in 2007. The PERED direct reduction process converts iron oxides, in the form of pellets or ...
DirectReduced Iron
· The DRI product is continuously discharged from the reactor and fed into a subsequent smelting reduction process. This can either be a shaft furnace, a submerged arc furnace or a smelting reduction process like HIsmelt (Orth et al., 2004), Fig., or Auslron (Laumann et al, 2010). The carbon content of the material is 6–8%.
Direct reduced iron process
· Figure: Shaft furnace for the direct reduced iron process. The heart of the direct reduction is the shaft furnace, which is filled from the top with lump ore and pellets. Carbon monoxide and hydrogen are used to dissolve out the oxygen in the iron ores. In contrast to the blast furnace process, however, these reduction gases do not result from the combustion of coke. Instead, these reducing ...
