Abstract

Quite a lot of plants are is using Dunite fines & lumps for long time, the reason for that are the following. In the sinter: The existing industrial experience for Sinter ranges has confirmed the following benefits: Higher reducibility of the sinter that translates to a lower coke consumption in the BF; Better hot strength or lower coke consumption at the same Hot Strength in the sinter plant; Better regularity of MgO in the slag; Higher productivity of the sinter plants; Lower percentage of screened off sinter before BF. In the Blast Furnace: Better alkali evacuation by starting the capture in the upper part of the BF, this will have an effect on: Better operation of the Blast Furnace; Reduction of coke consumption; Reduction of sulphur in pig iron; Better alkali evacuation; the efficiency of the way MgO is added in the BF could improve the fluidity of the slag and it would mean a better desulphuration.
