中文摘要：

在1350℃-1550℃，以石墨为还原剂及以氮气为保护气，对Fe203＋Cr203＋20％C体系进行了等温还原实验。并采用不同的动力学计算方法得到了Fez03＋Cr203＋20％C反应的动力学参数。结果表明，温度是Fe203＋Cr203＋20％C还原体系的重要影响因素。Fe203＋Cr2O3＋20％C还原反应的活化能为87．065kJ／tool，控速环节为相界反应。

英文摘要：

Synthetic Fe203 ＋Cr203 ＋20%C were isothermally reduced with graphite, protected by Nz, at 1350℃- 1550℃. And the kinetic parameters have been calculated by different methods. The results showed that temperature was aim portant factor of reduction of Fe203 ＋ Cr2 03 ＋ 20% C. The apparent activation energy of Fe203 ＋ Cr203 ＋ 20% C was 87. 065kJ/mol. Phase boundary reaction was the rate--controlling step.
