摘要
本文根据流态化预还原产物再氧化速度规律的研究，分析了温度、湿度、时间及氧浓度等因素对再氧化速度的影响，指出了环境中氧浓度是其主要影响因素．并提出了预防再氧化产生的有效措施．
According to the study of the regularity of reoxidization speed of prereduction iron ore-produced by fluidization process. the factors such as temperature.moisture.time.ox ygen concentration are analysed. It shows that the oxygen concentration in the atomosphere is the main factor,and the protective measures are also raised.
