Utilizing carbon composite iron ore briquette (CCB) could be an alternative way for improving heat efficiency and reduction of CO2 production in ironmaking process. One of the advantages is making use of low grade pulverized resource and the other is the low reduction temperature of iron oxide with carbon sources which has increased contact area during reduction. In this study, reduction behavior of iron oxide was investigated by adding flux components in CCB. The specimen includes dry mixed hematite and graphite with master slag into the briquette. Reaction processes were carried out at 1473K under nitrogen atmosphere in a super kanthal furnace. Specimens were observed in an optical macrograph to analyze reduction procedures. Gas analyzer was used to measure off-gas components. The results indicate that reduction of iron oxide was improved by increasing contact area between coal and ore in CCB by the formation of the liquid slag layer.
