采用四辊离心机,以铁尾矿为调质剂调质高炉熔渣生产矿渣纤维,分析了熔渣成分对成纤效果的影响,考察了不同酸度系数和辊速情况下纤维的物性变化趋势及机理.结果表明,采用离心甩丝法制备矿渣纤维,在辊速不变、熔渣酸度系数1.1~1.3、温度1350~1450℃条件下适宜成纤,所制矿渣纤维理化指标符合国家标准. A four-roll centrifuge was used to produce slag fibers from the blast furnace slag with iron tailings as the quenching agent. The influence of slag composition on the fiber forming effect was analyzed. The changing trend of the physical properties of the fibers under different acidity coefficients and roller speeds was investigated The results show that the slag fibers prepared by centrifugal spinning method are suitable for fiber forming with constant roll speed, slag acidity coefficient of 1.1 ~ 1.3 and temperature of 1350 ~ 1450 ℃. The physical and chemical indexes of slag fibers meet the national standards.
