摘要:
Uneven sintering is prevented in a sintering machine, and thus sintered ore having high strength and a high lump yield rate is manufactured. A method for manufacturing sintered ore comprising: charging sintering raw material comprising fine ore and carbon material on a circulatively moving pallet to form a raw material layer; igniting the carbon material on a surface of the raw material layer and sucking air from above the raw material layer down to below the palette so that the air is introduced into the raw material layer; and combusting the carbon material in the raw material layer to thereby manufacture sintered ore, wherein fuel gas is discharged from a nozzle at a flow speed of 40 Nm/s or more, the discharged fuel gas is combusted to generate combustion gas, and the combustion gas is used for the igniting the carbon material.
