PROBLEM TO BE SOLVED: To provide a blowing method capable of dispersion of a carbon source put into a furnace as a heat source during blowing, therefore capable of reducing a generation amount of dusts and improving yield of addition of the carbon source, when decarbonization processing of steels including a large amount of alloy contents (for example, a stainless steel or the like) is performed by using a furnace.SOLUTION: Provided is the decarbonization blowing method for decarbonization processing of molten iron for obtaining a high alloy steel by using a furnace, in which a smokeless coal having 3 mass% or less of a content of a volatile component is put into a furnace for compensating heat. |
