Keywords： iron ore

The whole melting curve of iron ore during sintering process was obtained, and the melting characteristics of iron ore were defined and explained. The whole melting process of mixture, mixed by iron ore and CaO reagent at basicity of 2.0 and 4.0, respectively, was observed using a SiC heating furnace with camcorder unit, and the melting curves of mixture that were relative height vs temperature curves were obtained. Besides, the melting characteristics of iron ore during sintering were introduced through defining some points in the melting curves, such as liquid forming temperature, inflexion temperature and flowing temperature, and the meaning of different shapes of the melting curves was clarified.
