SINTERED ORE MANUFACTURING METHOD

Proposed is a method effective for increasing production rate of sintered ore by using a granulated raw material for sintering contributing to reduction in size of a wet zone generated in a raw material charged layer on a pallet of a sintering machine. The method is a method for sintering in which a...

Beschreibung
Zusammenfassung:	Proposed is a method effective for increasing production rate of sintered ore by using a granulated raw material for sintering contributing to reduction in size of a wet zone generated in a raw material charged layer on a pallet of a sintering machine. The method is a method for sintering in which a compounded raw material for sintering containing not less than 10 mass% of fine powdery iron ore with a particle size of not more than 150 µm is granulated in a granulator by blowing steam into the granulator such that a granulated raw material for sintering to be charged onto the pallet is heated and humidified to have a temperature higher than a starting temperature of the compounded raw material for sintering before the charging into the granulator by not lower than 10°C.
