摘　　要：通过微型烧结试验和Factsage 6.2软件计算相结合的方法,研究了氟含量为0.5%(质量分数,下同)时,不同K、Na含量对白云鄂博铁精矿烧结液相流动性的影响。结果表明,随着铁精矿中K、Na含量的增加,K2O和Na2O在烧结液相中高度富集,CaF2含量相应减少,液相黏度几乎不发生变化,液相增多,致使液相流动性指数增大。Liquid phase fluidity of sinter produced by Baiyunebo iron ore concentrates with different content of K and Na when the content of F is 0.5 % was investigated by using mini-sintering test device and Factsage software. The result shows that the Kz O and Naz O highly enrich in the sinter liquid phase, the content of CaFz reduces cor- respondingly and the liquid phase viscosity changes less with the increasing content of K and Na. As the liquid phase content grows, the liquid phase fluidity index increase.
