Modified carbon material for producing sintered ore and method for producing sintered ore using the same

摘要

PROBLEM TO BE SOLVED: To provide a modified carbonaceous material for manufacturing a sinter ore capable of suppressing generation amount of NOx in exhaust gas with high productivity and a manufacturing method of the sinter ore.SOLUTION: There is provided a modified carbonaceous material for manufacturing a sinter ore which is a granular article of a raw material containing a carbonaceous material, an iron ore and a lime hydraulic binder and satisfies following A) to D). A) percentage of water washing grain size 0.25 mm or less constituting the granular article is 85 mass% or more. B) carbon content of the granular article is 21 mass% to 68 mass%. C) CaO content of the granular article is 4 mass% to 15 mass%. D) particle size of the granular article is 10 mm or less.SELECTED DRAWING: Figure 4
