PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a required quantity of high strength agglomerated ore according to operating condition. SOLUTION: In the method for manufacturing the non-fired agglomerated ore for charging into a blast furnace, water is added to an agglomerated-ore composition containing iron-oxide material, clay and hydraulic binder, and these are kneaded. Then extrusion is performed while applying vacuum deaeration, and the resultant formed material is subjected to curing. COPYRIGHT: (C)2005,JPO&NCIPI
