The rotary hearth furnace iron nugget process is in line with China's energy and resource condition. It has the advantages of short reaction time and high quality iron nugget. The fundamental study on the novel ironmaking process is meaningful. Based on CaO-SiO2-Al2O3-FeO quaternary slag system, the effects of slag basicity and Al2O3 content on the melting and flowability of slag were studied. Using the iron concentrate as raw material, the effects of different slag basicity and Al2O3 content on the reduction and melting separation behaviors of carbon composite pellets, such as the starting temperature of melting separation, the starting time of melting separation and the morphology of melting separation were studied. Then, the relationship between the properties of slag and the evaluation index of melting separation quality was established, which could provide standard for the selection of iron ore for the rotary hearth furnace iron nugget process.
