摘　　要：针对转炉加锰矿直接合金化工艺中锰收得率低的问题,研究开发了转炉出钢过程加锰矿进行直接合金化的工艺。结果表明:转炉出钢过程加锰矿直接还原合金化工艺无论从热力学还是动力学角度来说都是可行的。通过现场100 t转炉出钢过程加锰矿的生产试验可见,该工艺锰的收得率达到了80%以上,最高达到了95%,综合成本降低了3.43元/t以上。同时,该工艺不增加钢中的硫、磷等杂质含量,不污染钢液。In order to solve the problem o{ low manganese yield rate by adding manganese ore in the converter, the technology of converter tapping process with manganese ore direct alloying was studied. The results showed that the technology of converter tapping process with manganese ore direct alloying was feasible by the analysis of thermodynamics and dynamics. The plant practice of 100 t converter tapping process with manganese ore direct alloying showed that the manganese yield was more than 80 % and the maximum was 95 %, the comprehensive cost was reduced by more than 3.43 yuan/t. Meanwhile, the molten steel was rarely polluted and the content of sulphur, phosphorus was rarely increased.
