In the paper, the effects of adding dolomite, soft burnt dolomite and serpentine into infrared micro sintering furnace with different content levels of MgO on such properties as the fluidity of liquid phase and strength of bonding phase for iron ore powder are studied. The results showed that the sintering properties of adding soft burnt dolomite were superior to those of adding dolomite and serpentine, which mainly manifested in suitable fluidity index of liquid phase for iron ore powder within 0.6~1.2 at 1 280 ℃, the highest strength of bonding phase was 476.6 N and appropriate content of MgO was 2.0%. The sinter pot test results showed that the sinter added with soft burnt dolomite was with such advantages as high low temperature reduction degradation index, narrow drippage interval and small maximum pressure differences. The sintering of adding soft burnt dolomite is considered to be more beneficial to improving metallurgical properties of sinter based on the comprehensive comparisons of sintering properties of such three magnesium fluxes as the dolomite, soft burnt dolomite and serpentine.
