SLAG LUMPY ARTICLE AND MANUFACTURING METHOD THEREFOR
PROBLEM TO BE SOLVED: To manufacture a slag lumpy article capable of being used as raw material regardless of kinds of slags without generating solidification shrinkage pore and generating breakage due to internal strain, without needs for particular specialized facility at less labor and time and low cost.SOLUTION: A slag layer is formed by spreading as lamellar a granular slag having particle size to be porosity of 30 vol.% or more between particles, a molten slag is poured into gaps between particles by inflowing the molten slag into the slag layer and the molten slag is solidified to obtain a slag lumpy article consisting of the solidified slag and the granular slag. The slag lumpy article generates shrinkage pores due to shrinkage during solidification with dispersing in each cavities as the granular slag has a role to cut the molten slag to small, shrinkage strain is also dispersed and stress generated by γ deformation of CaO SiOmineral is also dispersed. Therefor large solidification shrinkage pore is hardly generated and large internal strain leading breakage of the lumpy article is hardly generated.SELECTED DRAWING: Figure 1
【課題】スラグの種類を問わず原料として使用できるとともに、凝固収縮孔が生じたり、内部歪みによる破壊が生じたりすることがないスラグ塊状物を、特別な専用設備を要することなく、少ない手間と時間で低コストに製造する。【解決手段】粒子間の空隙率が３０vol％以上となるような粒度を有する粒状スラグを層状に敷き詰めてスラグ層を形成し、このスラグ層に溶融スラグを流し込んで粒子間隙に溶融スラグを流入させ、溶融スラグを凝固させることにより、この凝固したスラグと前記粒状スラグとからなるスラグ塊状物を得る。このスラグ塊状物は、粒状スラグが溶融スラグを小さく分断する役割を果たすため、凝固時の収縮による収縮孔が個々の空隙内に分散して生成し、収縮歪みも同様に分散し、さらには、ＣａＯ・ＳｉＯ２鉱物のγ変態に伴い発生する応力も分散される。このため、大きな凝固収縮孔が生じにくく、また、塊状物を破壊に至らしめるような大きな内部歪みが生じにくい。【選択図】図１
