METHOD AND DEVICE FOR MANUFACTURING SLAG MATERIAL

摘要

Provided is a method for manufacturing a slag material, the method making it possible to adjust the characteristics of the slag material using a simpler method. A method for manufacturing a slag material, the method including: granulating a molten slag material S1 and then cooling the same, whereby the exterior of the slag material S1 is solidified to form an external shell, and the interior of the slag material S1 forms partially solidified semi-molten slag particles S2; and cooling the semi-molten slag particles S2. The semi-molten slag particles S2 may be held within a prescribed temperature range above normal temperature for a prescribed time prior to cooling.
