CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

2012-8-16  The sintering process consists of the passage of a heat and reaction front through a packed bed of solids. En general, the objective is to attain a temperature wave passing through the bed in such a way that a zone of incipient or partial fusion passes through the bed in order to agglomerate (sinter) the fines in the bed to a porous lumpy material suitable for feed to a blast furnace.

Evaluation of sintering behaviour based on ore characteristics

The quality of iron ore fines have been deteriorating, which has affected sinter quality and productivity adversely. New pretreatment and sintering technologies are therefore required to tackle the gradual change in the quality of iron ore fines. In the sintering process, iron ore fines are first granulated with fluxes such as limestone and coke breeze, and are then loaded and fired in a ...
