2008year4month9day Thermal volume changes and oxidation mechanisms in magnetite iron ore green pellets balled with 0.5% bentonite binder, as a function of raw material fineness and pellet porosity, are shown. When a pellet starts to oxidize, a shell of hematite is formed around the pellet while the core still is magnetite. Dilatation curves were measured under

2023year7month23day The transformation from traditional iron- and steelmaking technologies to green H2-based new technologies will require an improvement in the quality and purity of iron ore burden materials. Iron ore pellets are essential inputs for producing direct reduced iron (DRI), but the conventional binders, used in iron ore pelletizing, introduce gangue

2008year4month9day Magnetite iron ore pellets are produced by agglomerating moist, finely ground magnetite concentrate together with a binder in balling drums or balling discs to pellets, typically between 9 and 15 mm in diameter. In the Grate Kiln pelletizing process, the wet green pellets are loaded on a travelling grate with a bed height of 23 cm. ...

2023year3month15day In this study, this issue has been addressed by taking variable preheating temperature (850 °C, 950 °C, 1000 °C, 1100 °C) and residence time (20, 25, 30, 35 min.). Pellets were prepared from three iron ores with LOI (2.64, 4.85, and 9.19%). Effect of ore mineralogy on the drying characteristics of the pellet has been established.

2021year7month30day Recently, direct reduced iron (DRI) has been highlighted as a promising iron source for electric arc furnace (EAF)-based steelmaking. The two typical production methods for DRI are gas-based reduction and reduction using carbon composite pellets. While the gas-based reduction is strongly dependent on the reliable supply of

2018year3month27day High-temperature behavior of magnetite—coke composite pellet fluxed with dolomite was investigated by customized thermogravimetric analyzer (TGA) at 1573 K (1300 °C). The overall reaction was influenced by C/O ratio and dolomite content. The reduction was accelerated by increased amount of dolomite, while the samples with

2022year7month16day Magnetite is a kind of iron ore that is difficult to carburize. In order to improve the carburizing performance of magnetite pellet, pre-oxidation treatment was carried out, and the oxidation, reduction and carburization behaviors of magnetite pellet were investigated in this study. The magnetite pellet was oxidized in the air and carburized in

2021year2month8day The duration and temperature of the oxidation cycle play a key role during the iron ore pellet induration. Variation in oxidation degree of pellets gives rise to process instability, since it causes the variation of recuperated air in induration systems [].Microscopic examination of interface during the oxidation of magnetite pellets has

2022year3month23day The use of magnetite-based iron ore fines by means of fluidized bed technology has become a promising route to produce direct reduced iron. The significant influence of a prior oxidation treatment, which occurs in the preheating stage, on the subsequent fluidization and reduction behavior was observed in our previous study. As a

2020year9month1day In general, pelletization of iron ore is a process where the feed is a mixture of high-grade hematite/magnetite ore mixed with binder and coke breeze as additives to form pellets for the production of iron and steel [5]. Such types of initiatives can eradicate the crises of high-grade iron ore demand as pellet feed material as well as support ...

2020year2month1day The iron ore is first crushed into a powder, mixed with additives and a binder, and rolled into green pellets (10–15 mm in diameter) that are sintered to pellets in a furnace during pelletizing of iron ore [10,11]. The green pellets are thermally treated in the grate and rotary kiln to increase the mechanical strength [12–14].
