Abstract (en)
There are provided a method for producing a sintered ore and a sintering machine, the method being capable of safely producing a high-strength and a high-quality sintered ore with high yield using a downward suction type sintering machine. In a method for producing a sintered ore which includes charging a sintering raw material containing a fine ore and a carbonaceous material on a circular traveling pallet 8 to form a sintering bed 9, igniting the carbonaceous material in the formed sintering bed by an ignition furnace, and sucking air through a wind box provided below the pallet to produce the sintered ore, after the sintering bed 9 is ignited by the ignition furnace, a liquid fuel is atomized to have a particle size of 100 µm or less, is supplied at an upper portion of the sintering bed 9, and while being diluted to not more than a lower limit of combustion at ordinal temperature, is supplied into the sintering bed 9 from above the sintering bed 9. A sintering machine includes a liquid fuel spray device which sprays a liquid fuel on a sintering bed at a downstream side of an ignition furnace.
