摘　　要：对低品位铬矿和不锈钢粉尘进行铁浴熔融还原,研究了底吹H2对还原效果的影响.结果表明,在合适的还原条件下,含铬物料还原效果良好,铬收率达97%以上,且终渣残铬均低于0.1%;底吹H2可加速反应进程.Low-grade chromium ore and stainless steelmaking dust were reduced with carbon in iron bath, H2 was also used as reductant. The results showed that under an appropriate reducing condition, the Cr-containing materials were reduced effectively. The Cr recovery rate up to 97% was obtained while the Cr2O3 content in the end-slag kept below 0.1%. Furthermore, H2 blown through the bottom accelerated the reaction.

关 键 词：低品位铬矿 不锈钢粉尘 熔融还原 C-H2混合还原
