Abstract:It is generally known that the large formation amount of calcium ferrite is favorable for the iron ore sintering.The effects of sintering temperature and O2 content of inlet gas on the calcium ferrite formation characteristic of typical iron ores,including hematite,limonite,specularite and magnetite,were investigated.And the effect of O2 content on the microstructure of the roasted briquettes was also studied in detail.The results show the amount of calcium ferrite initially increases then decreases with the increase of the sintering temperature.The temperature of maximum calcium ferrite gener
