Effect of Oxygen Enrichment on Top Layer Sinter Properties
Sintering is a process in which iron ore fines along with limestone, dolomite, coke fines, quicklime GCP dust, flue dust, mill scale and return sinter are mixed with water to form nodules and then fired to form sinter. 1) Mix of these materials is then charged into pallet cars, where an ignition burner initiates combustion from the top part of the bed and air is supplied by down draft suction.

The more undersigned coke breeze not only reduces the permeability of bed but also flares immediately without sintering the material; this generates more sinter return-fines. Fluxes: Lime stone, dolomite, dunite, pyroxinite are the main source of fluxes used in Indian iron and steel industry.
