METHOD OF MANUFACTURING NONFIRED AGGLOMERATED ORE FOR BLAST FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a nonfired agglomerated ore for a blast furnace high in raw strength after molding.SOLUTION: There is provide a method of manufacturing a nonfired agglomerated ore for a blast furnace using an iron-containing raw material and a carbonaceous material-containing raw material as raw materials, including the steps of manufacturing a particle diameter adjusted raw material by mixing the iron-containing raw material and the carbonaceous material-containing raw material and adjusting the particle diameter so that the percentage of particle diameter of 0.5 mm or more and 2 mm or less is 10 mass% or higher and 40 mass% or lower, and of manufacturing an agglomerated ore by adding a binder and moisture to the particle diameter adjusted raw material, mixing and granulating them.
