초록
칼슘 페라이트는 소결광 제조 시 생성되는 자용성 소결 광물의 일종으로, 제철 공정의 소결광용 결합제 및 제강용 융제로 사용된다. 기존 소결광용 결합제 및 제강용 융제보다 용융온도가 낮아 결합제 및 융제로서의 효과가 우수하다. 본 연구에서는 제철공정에서 발생하는 다양한 산업부산물을 시작원료로 사용하여 칼슘 페라이트를 제조하였다. 칼슘 페라이트 물성을 분석·평가하기 위해, 시멘트 제조공정 시험법을 준용하였다. 더불어 칼슘 페라이트의물성을 평가하기 위해 결정분석, 파괴하중, 열분석 등을 시행하였다.
Abstract
Calcium ferrite is a major bonding material self-fluxed sintered ore, and it is used as a flux in the steelmaking process. Calciumferrite is more effective binder for making sintered ore and flux for steel making because of it's low melting temperature. In thisStudy, calcium ferrite was made by using variety industrial by-products from steel plant. The property of calcium ferrites wasinvestigated on the basis of test method using in the cement manufacturing process. Crystal analysis, compression test as wellas thermal analysis were carried out to evaluate physical properties of calcium ferrite.
