A. Formoso et al., Study of the iron ores mixture granulation in the sintering process. Part 2. Granulation index, REV METAL M, 36(4), 2000, pp. 254-265
The fitness fur granulation of a ore mixture used to make a series of sinte
ring in a pilot plant is studied. The quality indexes and the phases compos
ition of sinterings is determined. The best sintering structure is checked.
A serie of iron ores is classified as the granulation index (G index). The
G index evolution of the ore mixtures used by ACERALIA for the last years
is shown. An increase in productivity and a decrease in coke consumption in
the sinter strand is observed as the G index improves.
