转炉用高锰铁水冶炼存在金属喷溅、冶炼终点钢水余Mn含量偏低、冶炼操作不易控制等问题。通过充分利用终点Mn与渣系碱度、氧化铁间的关系特性，优化冶炼操作，达到提高冶炼余Mn含量、稳定冶炼操作的目的，终点余Mn含量由0.125%提高到0.196%，提升了铁水中Mn的利用率，减少了后期合金化操作成本。

Some problems included hot metal splash, low residual Mn content at smelting end point, difficult control of smelting operation and etc, were existed in BOF smelting used of high Mn molten iron as raw material. Through fully using the relationship characteristics of end point Mn with basicity in slag and iron oxide, optimizing smelting operation, the aim of enhancing residual Mn content in smelting and stabilizing smelting operation was achieved. The residual Mn content at end point was raised from 0.125%to 0.196%, and the utilization factor of Mn in molten iron was increased and the alloying cost in the late was reduced.
