本文研究了杂质元素对磁铁矿固溶体烧结和还原行为的影响。磁铁矿的主要杂质元素为Mg、Al、Ca、Mn和少量Si。对还原动力学和现象的影响分别进行了研究，并对每种元素以及它们的组合进行了研究。磁铁矿中掺杂元素的含量与工业生产的烧结矿相同。结果表明，CaO和MgO对磁铁矿的还原有显著的促进作用，而MnO对磁铁矿的还原有轻微的阻碍作用。
The present paper investigates the effect of impurity elements on sintering and reduction behaviour of magnetite solid solution. The main impurity elements of magnetite are Mg, Al, Ca, Mn and small amount of Si. The effects on reduction kinetics and phenomena are studied separately and for each element as well as combinations of them. The content of elements doped in magnetite are at the same levels as in industrially produced sinter. It is found that CaO and MgO significantly accelerate the reduction of magnetite to iron, MnO, however, slightly retards reduction.
