ore quality required for sinter iron

Sinter Quality and Process of Sintering Iron Ores –

2014-11-21  Sinter consists of many mineral phases produced during process of sintering of iron ores. The quality and properties of sinter are dependent on the mineral structure of sinter. However, since the sintering conditions are usually not uniform throughout the sinter bed, the phase composition, and therefore the sinter quality, varies in the sinter bed. The structure of sinter is not uniform.

CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

2012-8-16  sinter feed with good permeability from ignition until burn-through is required for efficient operation of a sinter plant. In this regard it is necessary to consider the widely held and simplistic view that sinter feeds containing iron ores with high ultra-fines content have low-pre-ignition permeability. A number of factors influence the granulation characteristics and permeability of sinter feeds. Attempts to improve granule characteristics of sinter
