锰硅铁合金炉外精炼的基础研究

锰硅铁合金炉外精炼的基础研究摘要：

锰硅铁合金作为一种重要的合金材料，在钢铁冶金、化工等行业得到广泛应用。针对锰硅铁合金生产过程中所存在的问题，本文运用炉外精炼技术进行锰硅铁合金的精炼，研究了不同操作参数对精炼效果的影响，分析了精炼后锰硅铁合金中夹杂物的变化规律及对合金性能的影响。

在不同的操作参数下，研究发现，在炉外精炼温度为1550℃，精炼时间为45min，保温时间为30min，亚氯酸钾加入量为0.2%的条件下，精炼效果最佳，夹杂物含量明显下降，合金的物理性能和化学成分均得到显著提高。

研究表明，在锰硅铁合金的炉外精炼过程中，操作参数对精炼效果有重要影响，通过合理的操作参数选择，可以有效降低合金夹杂物含量，提高合金的物理性能和化学成分，为锰硅铁合金的生产提供了一种新的思路和方法。
