Ore Sintering - an overview ScienceDirect Topics

2010-4-2  Some domestic ores are also used in China together with the imported ones, from which 45% of steel in the world is produced. In the sintering process, iron ores are usually blended and mixed with fluxing materials, e.g., limestone and burnt lime, and fuels (so-called agglomeration agents), e.g., coke, anthracite, and some recycle dusts.

[PDF] Ore Assimilation and Secondary Phases by

2021-1-20  During the iron ore sintering process, two types of particles are present in the sinter bed: (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt. The quality of the final sinter is particularly determined by the secondary phases and their bonding ability.

Combustion characteristics in an iron ore sintering

2006-5-1  Combustion characteristics in an iron ore sintering bed can be significantly affected by the melting of iron ores, which influences the bed permeability and thereby disturbs airflow. Consequently, the amount of iron ore melting should be controlled to maintain appropriate combustion conditions and to produce sintered ores of high quality.

Cycle behaviour of iron ores in the steam-iron process ...

2011-6-1  The elemental composition of the iron ores is shown in Table 2.The iron oxide (Fe 2 O 3) fraction in the ores ranges from 82 wt% (Densinox) to 95.7 wt% (Micafer).SiO 2, Al 2 O 3 and CaO, as main impurities, are present in different proportion for each material. It can be seen that the amounts of SiO 2 and Al 2 O 3 in the samples decrease for increasing values of Fe 2 O 3 content.

Multi-time-scale TFe prediction for iron ore sintering ...

2019-8-1  Empirical experiences show that a 1% decrease of iron grade (TFe) in produced sinter turns into a 2% increase of BF fuel ratio and a 3% decrease of BF output . So, the TFe is an important quality index for a sintering process. It takes about 2 h from the loading of iron ores to the discharging of sinter in a sintering process.
