Title of Invention	"PRODUCING METHOD OF BLAST FURNACE COKE"
Abstract	A producing method of blast furnace coke includes: warming a coal-derived liquid caking additive to a temperature equal to or higher than a liquefaction temperature at which the viscosity of the coal-derived liquid caking additive becomes 100 cP and equal to or lower than a liquefaction temperature at which the viscosity of a petroleum-derived solid caking additive becomes 100 cP; preparing a mixed caking additive by dissolving the petroleum-derived solid caking additive in the coal-derived liquid caking additive; preparing a mixed raw material by mixing a coal for coke making and the mixed caking additive; and carbonizing the mixed raw material.
