摘　　要：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.The blast furnace slag quenched by iron tailings as modifier was used to prepare slag fiber with the equipment of four-roll centrifuge. The effect of composition on fiber-forming was analyzed, while the trend and mechanism of fiber properties was examined at different acidity coefficient （Mk） and roller speed. The result shows that this method is proper to make slag fiber with the constant roll speed, maintaining the Mk between 1.1-1.3 and the temperature of 1350-1450℃, the physical and chemical indicators of slag fiber meet the national standards.
