Interfacial tension and contact angle were obtained directly from a numerical solution of the Young-laplace equation. Surface tension of SUS304 was found to be 1467 mN.m in Ar-atmosphere which was considerably lower than that of pure iron. This may be due to the existence of surface active elements such as (Cr, Ni and Mn etc. in SUS304. Interfacial tensions of SUS304 in contact with CaO-Sio2-Al2O3(CaF2) slags were in the range of 925 to 1 148 mN/m. The contact angle between SUS 304 and various pedestal was about 120° regardless of pedestal oxides. A12O3. TiO2 and SiO2. Contact angles between SUS304 and the pedestal alumina coexisting with liquid CaO-SiO2-Al2O3CaF3) were in the range of 125° to 142°.
