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.
