Abstract

PURPOSE: To improve problems of environmental sanitation and at the same time to make magnetic recovery possible and increase efficiency, by using as sand material for sand blast use the pulverized converter slag, which is obtained by pulverizing converter slag, which is produced as a by-product in steel making by a converter.
CONSTITUTION: Melted converter slag produced in a converter is contained in a tundish. Then, it is discharged from an outlet provided in the lower part of a tundish. At this time, from the nozzle provided at the end in the lower part near the tundish, oxygen-rich compressed air is blown to the flowing melted slag, and then the slag is cooled suddenly and is made to scatter; and thereby pulverized converter slag is obtained. The specific gravity of this pulverized slag is 2 to 3. By this, the time for sand blast processing can be shortened. Since FeO, etc. are properly oxidized, it is easy to recover them with a magnet.
