Viscosity of Ladle Refining Slags and Structural Analysis Using Micro-Raman Spectroscopy

摘要：

　　The structure-viscosity relationship of the low-silica(SiO2 ≤ 10%)calcium aluminosilicate ladle refining slags was investigated using Raman spectroscopy.The viscosity of ladle refining slags decreased with increasing both CaO/Al2O3 and CaO/SiO2 ratios,respectively.However,the effect of the former on the viscosity of slags was larger than that of the latter.By employing the Neuvilles structure model,it was demonstrated that the aluminate and silicate structural units are more effectively modified by increasing the CaO/Al2O3 ratio at fixed silica content.
