MANUFACTURING METHOD OF SINTERED ORE

摘要

PROBLEM TO BE SOLVED: To achieve enhancement of reducibility of a sintered ore and suppression of reduction degradation property at same time.SOLUTION: There is provided a manufacturing method of a sintered ore using a carbonaceous material post addition method by adding a part of or all carbonaceous material after a predetermined time passes after initiation of mixing and granulation, where 75 mass% or more of total amount of carbonaceous material is added after 50% or more of total mixing and granulation time passes after initiation of mixing and granulation are added and the MgO content of the sintered ore is 1.5 mass% to 2.0 mass%.SELECTED DRAWING: Figure 8
