50.3.1.1 Example—Burden Distribution Change. Iron ore sinter /pellets are redirected from the wall of the blast furnace to the center using the bell-less top charging equipment. The top gas utilization (TGU) improves from 47.5 to 49.0% (an increase of 1.5%) due to better contact of the ferrous burden with the CO-rich gas in the furnace center.
Hot metal production using sinter and pellets in the blast furnace is compared, considering aspects like; blast furnace productivity, …
different routes were used to sinter pellets to around 90% relative density: 1) firing high green density pellets for 30 minutes at 1400°C or 2) firing low green density pellets for 240 minutes at 1400°C. The grain size of pellets produced at condition 1 had a grain size of 7.9 µm while those prepared at condition 2 had a grain size of 15.3 µm.

2.2 Comparing Sinter and Pellets Sinter and pellets are agglomerated forms of iron ore, both suitable for use as blast furnace burden materials. The principle difference between sinter and pellets arises from the type of raw materials used in their preparation and the nature of the sinter and pelletizing agglomeration processes.
Physicochemical behaviour of the pellets, sinters and its mixture (60% pellets: 40% sinter) is investigated by a series of smelting and quenching experiments. For all ferrous raw-material beds,
Emissions of CH4 are reported in Table 8.2a of the EMEP/ CORINAIR Emission Inventory Guidebook for sinter and palletising plants. For sinter plants using coke breeze an emission factor of 50 mg CH4 per MJ was reported and a range of coke input of 38 to 55 kg coke per tonne sinter was reported.

The pellets were then cooled naturally to room temperature, and then transferred to optical dilatometer for subsequent processing. Sintering Oxidized magnetite pellet is now subjected for sintering process in optical dilatometer (Misura® HSM–ODHT) and captures the shrinkage of pellet, schematic of which is shown in Figure 1.
Iron ore, pellets, and sinter were reduced with hydrogen at 800 °C to understand the degree of reduction and the mineralogical aspects. The weight loss of goethite and limonite iron ore was noticed to be lower than that of …
Better quality wet, dry, preheated, and fired pellets can be produced with combined binders, such as organic and inorganic salts, when compared with bentonite-bonded pellets. While organic binders provide sufficient wet and dry pellet strengths, inorganic salts provide the required preheated and fired pellet strengths. Keywords iron ore

2. 2 DEFINITION OF SINTERING Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. 3. 3 TYPES OF SINTER • NON FLUX SINTER • FLUXED SINTER • SELF FLUXED SINTER • SUPER FLUXED SINTER 4.
Iron ore fines were mixed with 0.5% bentonite and 1.87% coke equivalent to 1.5% carbon. As it has been found in earlier studies that 0.5% bentonite [] and 1.5% carbon [] are the optimum quantity requirement in acidic hematite pellets, the above mix proportion was used for this study.After making the pellet mix, the mixture was pelletized in a disk …
The reduction degradation characteristics of typical sinter, pellet and lump ore were tested with the reducing gas conditions simulating two kinds of iron-making processes.
required to produce 0.9 Mg (1 ton) of product sinter. 12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel.
