Method for sintering fine iron ore using dual ignition system

摘要

A method for sintering fine iron ore using a dual layer system is disclosed. Two layers of sintering charge are placed on a train of pallets and each of the layers is set on fire at given intervals of time to perform sintering of the charge. The upper layer of the charge is set on fire when the front flame point of the lower layer reaches grates of the pallet. The upper layer may contain, as a solid fuel, coal containing 10 wt% of higher of volatile matter.
