안정화 처리를 위한 전기로 제강분진의 물성
A Study on the Properties of Electric Arc-Furnace Steelmaking Dusts for Stabilization Processing
초록
전기로 제강분진의 물성을 파악하기 위하여 분진의 성분, 형상, 입도, 자성, 비중, 공극율 및 용출에 관한 성질을 조사하였다. 분진의 대부분은 서브 마이크론에서 수십 마이크론에 이르는 다양한 크기의 구형입자들이 서로 응집된 상태이고, 큰 입자에는 철분이 그리고 작은 입자에는 아연이 주로 농집되며, XRD 분석으로는 franklinite(
This study was carried out to understand the properties of the E.A.F. steel-making dusts for stabilization processing. The properties are related to mincral composition, shape, particle size, magnetism, density, porosity and leaching characteristic. the dust particles, the size of which ranges from sub-micron to tens-micron, were mainly spherical like balls that were agglomerated each other: the large particles were generally Fe-rich and the small particles were spherical like balls that were agglomerated each other: the large particles were franklinite (ZnFe
