Viscosity Measurements of Molten Fe–O–SiO 2 , Fe–O–CaO–SiO 2 , and Fe–O–MgO–SiO 2 Slags

Viscosity data for Fe–O–SiO2, Fe–O–CaO–SiO2 and Fe–O–MgO–SiO2 synthetic slags were obtained using a rotating cylinder viscometer. Parameters investigated include: temperature, Fe/Si ratios, and N MeO/N SiO2 ratios (MeO = CaO or MgO). The oxygen partial pressure was fixed at 6.08 × 10−6 N/m2.
