摘　　要：通过对现行高硅锰硅合金在冶炼原理和工艺制度上的剖析,找到了冶炼困难的主要原因——电制度欠合理及混合料入炉而形成的以硅酸锰为主导的各种反应、因炉温低而生成的"MnO+C+SiO_2+C+MnSiO_3+C+熔渣"共熔体,阻碍和限制了Si、Mn的直接还原,造成了其熔体处于难控制、难调整状态,而要从其中还原Si、Mn较为困难。新的高硅锰硅冶炼方法,从原工艺理论上进行了阐述,采取了相应的措施,达到了"提Si保Mn降C"的目的。This paper analysed current high silicon Mn-Si smelting by theory and technology system, finding out primary cause which was unreasonable electric system, mixture charging and forming manganese silicate as the leading factor of all kinds reaction, to form MnO＋C＋SiO2＋C＋MnSiO3＋C＋slag solid dispersion due to low furnace temperature, impeding and limiting direct reduction of Si,Mn, making the melt in difficult status to control and adjustment. It was difficult to reduce Si,Mn from melt. The new smelting process of high silicon Mn-Si bases on original technology theory, using corresponding measures to extract Si, ensure Mn, decrease C.
