摘要: The dynamic interfacial phenomena during high-temperature reaction between an Fe-Al alloy droplet and a CaO-SiO2-Al2O3 slag were analyzed by evaluating the thermocapillary, solutocapillary, electrocapillary effects. magnitudes of these effects determined using local equilibrium model utilizing kinetic data to determine composition, temperature, electrical potential. effect was found be dominant. It contributed approximately 85 pct maximum depression while solutocapillarity 15 pct. thermocapillary negligible. In this work, gradient tension along interface due solutocapillary estimated, i.e., Delta(gamma m-s) 440 mN/m over 1- 2-mu m distance.
