Abstract

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 K2O and Na2O highly enrich in the sinter liquid phase, the content of CaF2 reduces correspondingly 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.

Key words

iron ore concentrates / sinter / liquid phase fluidity.
