Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a high crushing characteristic by blowing steam against molten slag before being cooled by cooling water. SOLUTION: Molten slag 10 discharged from the main body 1 of a blast furnace is cooled by cooling water from a water injection nozzle 4a to manufacture water granulated slag. In the process, steam 20 is blown against the molten slag 10 before being cooled by the cooling water.
