Experimental studies of the viscosities in the CaO-Fe sub n O-SiO sub 2 slags

In the present work, the viscosities in the CaO-Fe sub n O-SiO sub 2 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 5.5-45.5% mass, FeO between 10....

Description
Summary:In the present work, the viscosities in the CaO-Fe sub n O-SiO sub 2 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 5.5-45.5% mass, FeO between 10.0-70.0% mass, and one measurement each in the binary Fe sub n O-SiO sub 2 and CaO-SiO sub 2 melts. The measurements have been carried out in the temperature range of 1423-1753K. 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 1723K. Good agreement between the calculated results and the experimental data has been obtained.
