제목 Fabrication of mineral fiber from steel-making slag via melt spinning method
초록 Mineral fiber, or be called mineral wool when it assembles in large amounts, is a kind of wide applied man-made material with excellent thermal and acoustic insulation properties. In this work, mineral fiber is produced via melt spinning method by using steel-making slag as raw material. Two critical experimental parameters for fabrication are investigated: melt pouring temperature and spinning speed of rotation wheels. The mineral fibers produced under the condition of melt pouring temperature 1500°C and spinning speed 4000 rpm show the smoother surface and most quality; while the others have rough surfaces or with heavy shots. In general, mineral fibers with the size in the range of 12~49 µm in diameter and 8~130 mm in length can be fabricated by this method, and the production rate is more than 34 wt.%, which can be up to 57 wt.% at maximum.
