摘　　要：根据合金钢连铸保护渣多组分组成特点,设计了CaO-SiO2-Na2O-CaF2-Al2O3-MgO-MnO-BaO渣系,研究了该渣系组成与粘度的关系。研究结果表明,该渣系保护渣的粘度在CaO/SiO2=0.6～1.1、CaF2=5%～15%、Na2O=2%～10%、MgO=0～5%、MnO=0～5%、BaO=0～7%范围内随着各组分含量增加而降低;在MgO=5%～8%、MnO=5%～8%、BaO=7%～12%范围内,连铸保护渣的粘度基本不变。通过研究还得出了粘度与组分之间的回归方程,对连铸保护渣的设计具有积极的指导意义。According to the muhicomponent characteristics of mould fluxes of the alloy steel , this paper designed the slag system CaO- SiO2 - Na2O- CaF2 - Al2O3 - MgO - MnO - BaO and researched the relationship between viscosity and the compositions of the slag system. The results showed that , the viscosity of the slag decreased with increasing of various components in the rangeofCaO/SiO2=0.6-1.1, CaF2=5%- 15%,Na20=2% - 10%,MgO=0-5%,MnO=0-5% and BaO=0-7% , while kept invariant in the range of MgO = 5% - 8% ,MnO = 5% - 8% and BaO = 7% - 12%. The regression formula regarding viscosity and fluxes composition was also obtained, which has positive effect on the design of mould fluxes.
