Abstract [en]

Reduction behaviour and textures formed during laboratory simulated BF tests with olivine pellets are presented and discussed. Test design is based on gas and temperature profiles during operation at a high and a low pulverized coal injection (PCI) rate with a low-volatile coal in the LKAB experimental blast furnace (EBF). Texture differences, introduced prior to a reduction degree of 40 percent, are observed in the iron oxide in the pellet core and in the Femet pellet periphery. A simulated high PCI rate decreases the reduction time of the pellets. The olivine pellets investigated are well suited for blast furnace operation at different PCI rates and accordingly different production rates.
