Document Type and Number:
WIPO Patent Application WO/2007/061126
Kind Code:
A1
Abstract:
A process for sintered-ore production which comprises a granulation step, a drying
step, and a sintering step. The granulation step comprises adding water and a
binder to a raw material to be sintered which contains a carbonaceous material and
granulating the mixture to produce raw granules to be sintered. The drying step
comprises drying the raw granules to be sintered to thereby produce dried raw
granules to be sintered which have a water content of 4.0 mass% or lower. The sintering
step comprises introducing the dried raw granules into a sintering apparatus
and sintering the granules.
