Abstract: 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 m/s or more, the discharged fuel gas is combusted to generate combustion gas, and the combustion gas is used for igniting the carbon material.

Abstract: A granulated material is provided which enables a reduction in the amount of adhesion of the granulated material to a conveyor junction. A granulated material includes sludge in an amount of greater than 30 mass % and 90 mass % or less and sintered ore powder in an amount of 10 mass % or greater and less than 70 mass %. The granulated material includes granulated particles in which at least a portion of the sludge adheres to at least a portion of the sintered ore powder.
