摘　　要：为控制锰硅冶炼中渣的酸碱度,根据生产实践,对高硅锰硅合金炉渣的三元碱度与渣中MnO、SiO_2含量的关系作了分析,同时也分析了锰硅合金中C量与Si量的关系,利用数学中最小二乘法找到了炉渣碱度与渣中MnO含量、SiO_2含量的经验关系式以及合金中C量与Si量的经验关系式,确定了冶炼高硅锰硅合金的合理渣型,保证了锰硅合金的冶炼指标。In order to control slag acidity-basicity in smelting ferromanganese-silicon, combined with production practice, it makes analyses on the relation between slag ternary basicity of high silicon ferromanganese-silicon and MnO, SiO2 in slag respectively. Meanwhile, it analyzes the relation to C content and Si content of ferromanganese-silicon. It finds out both experiential formulae about slag basicity with MnO content, SiOz content in slag respectively and about C content with Si content in alloy by means of least square method. The determination of rational slag pattern guarantees the smelting of ferromanganese-silicon.
