METHOD AND DEVICE OF PRODUCING SLAG MATERIAL
To adjust characteristics of a slag material by an easier method.SOLUTION: There is provided a method of producing a slag material, comprising a step of pulverizing and thereafter cooling molten slag S1 to form half-molten slag particles S2 each formed of an outer shell, i.e., its outer part having been congealed/solidified and of a partially congealed/solidified inner part, and a step of cooling the half-molten slag particles S2. The half-molten slag particles S2 may be kept in a specified range of a temperature higher than an atmospheric temperature for a specified period of time prior to cooling the same.SELECTED DRAWING: Figure 1
【課題】スラグ材の特性をより簡易な方法で調整する。【解決手段】スラグ材の製造方法は、溶融スラグＳ１を粒状化し、冷却することで、外部が凝結固化して外殻が形成され、内部が部分的に凝結固化した半溶融スラグ粒子Ｓ２を形成することと、半溶融スラグ粒子Ｓ２を冷却することと、を有する。半溶融スラグ粒子Ｓ２を、冷却する前に所定時間、常温を上回る所定の温度範囲に保持してもよい。【選択図】図１
