摘　　要：为了探讨含锌球团的还原行为与温度的关系,本文首先对内配碳含锌球团还原进行动力学分析,分析得出了反应前中后期的主要限制因素分别为碳气化速度、含锌球团界面上的反应速度、后期扩散,还原温度的升高对这三种限制因素均有促进作用,然后通过球团还原试验得出较佳的还原温度为1200℃。In order to investigate the relationship between the reduction behavior of zinc-containing pellets and temperature,the kinetic analysis of the reduction of zinc-containing pellets in the inner carbon is firstly carried out.It is concluded that the main limiting factors in the middle and late stages of the reaction are carbon gasification rate and The reaction rate,late diffusion and reduction of the reduction temperature at the zinc pellet interface promoted these three limiting factors,and then the optimum reduction temperature was 1200℃ through the pellet reduction test.
