Paper Title:
Research on Influence Law of Fuel Structure for Low-FeO Sintering
  Abstract

Micro–sintering equipment was applied to simulate sintering process of iron ore. FeO content of sinter-samples under different fuel structures was measured, and then the effect of fuel structure on fluidity of liquid phase and strength of bonding phase were analyzed in this paper. The proper fuel structure was finally discussed under low FeO sintering condition. The results show that: when anthracite was adopted as partial substitution of coke breeze as part of solid fuel, FeO of sinter reduces and self-strength of bonding phase increases. Although fluidity of liquid phase reduces, the fluidity index it is still above 0.8, which can meet the liquid volume needed for sintering. When CDQ powder is used as part of solid fuel, FeO of sinter also reduces, but fluidity of liquid phase and self-strength of bonding phase reduce a little due to its low combustibility. Taking experimental results and practical production together into account, it can be concluded that proper fuel structure that meets low FeO sintering should be “70% coke+30% anthracite”.
