초록
Mineral fiber, or be called mineral wool when it assembles in large amounts, is a kind of wide applied manmadematerial with excellent thermal and acoustic insulation properties. In this work, mineral fiber was produced via meltspinning method by using iron blast furnace slag as raw material. Two critical experimental parameters for fabrication wereinvestigated: melt pouring temperature and rotating speed of spinning wheels. The mineral fiber produced under thecondition of melt pouring temperature 1500oC and spinning speed 4000 rpm, showed the smoother surface and most quality,while the others had rough surfaces or with heavy shots. In general, mineral fibers with the size in the range of 12~49 μmin diameter and 8~130 mm in length can be fabricated by this method, and the production rate is more than 34 wt.%,which could be up to 57 wt.% at maximum.
