Al-O equilibria in molten Fe-Al alloys were experimentally investigated. Molten steel with varying Al content (0.01-10 mass%) was equilibrated with a pure Al 2 O 3 (s) crucible at 1 873 K in an Ar atmosphere with 3 vol% H 2 . The oxygen content of steel with Al content higher than 1.0 mass% was found to be much lower than that found in previous works, while the oxygen content for Al content less than 1 mass% was found to be slightly higher, resulting in a smaller equilibrium constant. The interaction parameters as well as the equilibrium constant of the Al-O equilibria in molten steel at 1 873 K were reevaluated in the present study. The equilibrium for the Al deoxidation of molten steel was well represented up to 10.0 mass% Al using the reevaluated parameters.KEY WORDS: deoxidation; aluminum; equilibrium constant; interaction parameters. 1483© 2009 ISIJ (and a few equilibria at other temperatures) measured in previous studies.

“…The maximum oxygen concentration at solidifying interface becomes 0.045 mass% with k0 O =0.1 and aluminium oxide will not be formed since the oxygen can be supersaturated. According to Hilty and Crafts, 23) and Novokhatskiy and Belov,24) the oxygen could be supersaturated at least 0.045 mass%.…”

Surface tensions of low carbon slabs and 16 mass%Cr stainless steel were estimated using a surface thermodynamic model proposed by Mukai et al. As an application of the model, an index to evaluate the driving force for the fine bubble entrapment by the solidifying shell, the Mukai-value, M, was calculated from the surface tension values. The relationship between Mukai-value and number of entrapped bubbles was discussed. A linear relationship was found between the number of captured bubbles and Mukaivalue. In the previous work, the Mukai-value was used as a relative scale to evaluate the driving force for the movement of bubbles. However, by calculating the M from the surface tension values by the surface thermodynamic model, physically reasonable Mukai-values could be obtained.
