摘要：
In the present work, the viscosities in the CaO-FenO-SiO2 ternary system have been measured by the rotating cylinder method involving a spindle and crucible made of iron. Nine slag compositions in the ternary system have been chosen with CaO varying between 5.5 and 45.5 pet mass, FeO between 10.0 and 70.0 pet mass, and one measurement each in the binary FenO-SiO2 and CaO-SiO2 melts. The measurements have been carried out in the temperature range of 1423 to 1753 K. The viscosity in this system is described as a function of temperature and composition using the model approach developed earlier at the present laboratory. The isoviscosity lines have been predicated at 1573, 1673, and 1723 K. Good agreement between the calculated results and the experimental data has been obtained.
