Emission Optimized Sintering (EOS®) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:
Our innovative sintering and pelletizing solutions are based on over 60 years' experience and world-class R&D. Outotec Traveling Grate Sintering is suitable for sintering a wide …
Sintering is the most widely used agglomeration process for preparing iron ore fines for blast furnace applications. We are using our expertise in iron ore sintering and evaluation of blast furnace burdens to assist industry to maximise the value of their resources, optimise product quality and reduce their environmental footprint.
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
Sintering: A Step Between Mining Iron Ore and Steelmaking By Alison Cestari 06.11.2019 The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3).
Direct reduction (DR) of iron ore with hydrogen is a potential route for near-zero CO 2 steelmaking, but vertical shaft DR reactors require that iron ore fines must first be pelletized. This study reports an investigation of the pelletization and subsequent sintering behaviour of titanomagnetite (TTM) ironsand, which is the main iron ore feedstock for New Zealand's steel …
Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. Pellet plants sized from 1.2MTPA to 9MTPA Engineering and …
For sintering process, (a) take the igniting device out of the vacuum chamber and then close the vacuum chamber; (b) open the valves I and IV, and close the vale II, and adjust the valves III and IV. The air blower was closed when the temperature of exhaust gas reached the maximum value, which indicated that the sintering process was finished.
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....
A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and iron-bearing materials separately, which leads to a …
Iron ore is typically characterized chemically, physically, and mineralogically. The effect of iron ore characteristics on sintering is mainly through their impact on the granulation and densification processes. With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to their sinter plants more frequently than ever before.

Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process. Iron ore is typically characterized chemically, physically, and mineralogically. The effect of iron ore characteristics on sintering is mainly through their impact on the granulation and densification …
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, …
The present paper reviews the sintering process that the mixture follows, once granulated, when is loaded onto the sinter strand. There, the sinter mixture is partially melted at a temperature...
The iron ore slimes can also be utilized in sinter making with or without beneficiation through hybrid pellet sintering. In hybrid pellet sintering process, iron ore concentrate of relatively finer size is first converted into micro-pellets and these micro-pellets are used in …
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.

Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of...
A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and iron-bearing materials separately, which leads to a layered structure. The iron-bearing materials consist of iron ore pellets, lump ore, and sinter. When the charge material descends, it is reduced by CO and H 2. In the ideal situation, iron-bearing …
Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. …
