本文对不同预还原度的铁矿球团在铁碳熔体中熔融还原的规律进行了实验和理论研究．针时熔融还原反应特点，提出了表观FeO浓度概念．根据传质理论和球团矿熔融还原的特性，建立了反映球团矿在铁碳熔体中熔融还原反应规律的双相传质模型．实验和理论计算结果表明，球团预还原度和熔化速率等因素对熔融速率影响较大.
In this paper, different prereduction iron ore pellets melting reduction in iron-carbon melt experiments conducted and theoretical studies. The characteristics of the molten reduction reaction of the needle, put forward the concept of apparent FeO concentration. According to the theory of mass transfer and the characteristics of pellet melting and reduction, a two-phase mass transfer model was established to reflect the rule of the melting and reduction reaction of pellets in iron-carbon melt. Experimental and theoretical calculations show that the pellet prereduction degree and the melting rate and other factors have a greater impact on the melt rate.
