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 multicomponent characteristics of mould fluxes for alloy steel,this paper designed the slag system CaO-SiO2-Na2O-CaF2-Al2O3-MgO-MnO-BaO and researched on the relationship between viscosity and the compositions of that slag system.The results showed that,the viscosity of the slag decreased with increasing in the range of CaO/SiO2=0.6～1.1,CaF2=5%～15%,Na2O=2%～10%,MgO=0～5%,MnO=0～5% and BaO=0～7%,kept invariant in the range of MgO=5%～8%,MnO=5%～8% and BaO=7%～12%.The formula regarding viscosity and fluxes composition has also been regressed.This research has positive effect for the design of mould fluxes.
