METHOD AND APPARATUS FOR PRODUCING WATER-GRANULATED SLAG
PROBLEM TO BE SOLVED: To provide a method capable of producing high quality water-granulated slag at relatively low cost.SOLUTION: A water-granulated slag production method according to the present invention, which is a method for producing water-granulated slag obtained by water-granulating molten slag, includes the steps of: flowing down the molten slag; injecting a water jet to the molten slag in the flowing down state in a V shape or a reverse pyramid shape having a vertex on the downstream side in the flowing down direction; and covering crushed slag particles with cooling water after the injection step.SELECTED DRAWING: Figure 1
【課題】本発明は、比較的低コストで良質な水砕スラグを製造できる方法を提供することを課題とする。【解決手段】本発明に係る水砕スラグの製造方法は、溶融スラグを水砕して得られる水砕スラグの製造方法であって、上記溶融スラグを流下させる工程と、上記流下状態の溶融スラグにその流下方向下流側を頂点とするＶ字型又は逆多角錐型に水ジェットを噴射する工程と、上記噴射工程後に、粉砕されたスラグ粒子を冷却水で被覆する工程とを備えることを特徴とする。【選択図】図１
