Dri Refractories Shaft Furnace

HBI is made by compressing DRI discharged from the MIDREX® Shaft Furnace at ≥ 650° C into pillowshaped briquettes with a typical size of 30 x 50 x 110 mm and a density ≥ 5 gm/cc. No binder is used to make HBI. Hot DRI (HDRI) HDRI can be transported to an adjacent EAF at up to 650° C to take advantage of the sensible heat, which allows the steelmaker to increase productivity and reduce ...

 · Midrex shaft furnaces with m, m, and m shaft diameters having annual production capacities of 800,000 tons, 1 million tons and million tons of DRI respectively constitutes different development stages. Later with the improvements made, the capacity has increased to a level of million tons per year in 2007, which is comparable to that of a fairly good size blast furnace ...

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 ...

 · 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 .

 · 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%.

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 ...

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 ...
