CARBONACEOUS MATERIAL INTERIOR GRANULATION PARTICLE FOR MANUFACTURING SINTER ORE AND MANUFACTURING METHOD OF SINTER ORE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for suppressing firing of a carbonaceous material by consuming oxygen by an oxidization reaction in a coating film during burning a sinter raw material, capable of avoiding limitations of production amount of the sinter ore.SOLUTION: There is provided a carbonaceous material interior granulation particle for manufacturing a sinter ore having a carbonaceous material core and an outer layer by covering around the carbonaceous material core with a mixed powder consisting of an iron ore powder and a CaO resource powder and the content of FeO in the iron ore powder is 1.0 mass% or more.SELECTED DRAWING: Figure 1
