Summary:PROBLEM TO BE SOLVED: To manufacture a sintered raw material containing many pseudo-grains through mixing and granulating raw materials consisting of fine ores, auxiliary materials, and carbonaceous. SOLUTION: In a process for manufacturing iron-making raw materials by blending ore raw materials such as fine ores, auxiliary materials, and such as cokes, granulating them via a mixing step, and sintering the obtained pseudo- grains, this method includes manufacturing preliminary grains which are to be core particles with an average particle size of 1 mm or larger, by previously mixing and granulating a part of sintering raw materials which consist of the ore raw materials, auxiliary materials, and charcoal wood, then blending the remaining raw materials for sintering, adding water, and charging the preliminary grains at the end of a step of granulating the pseudo-grains (after finishing 70-90% of the step).
