ABSTRACT:
A method and apparatus for post-melting treatment of molten steel in which a container of molten steel is subjected to a sub-atmospheric pressure generated by air ejector means and, simultaneously, to an inert gas purge. A higher inert gas purge rate is used with an air ejector system than with a steam jet ejector system because the treatment pressure in the air ejector system is higher than the treatment pressure in the steam jet system. Heating means for at least partially compensating for heat loss is also disclosed.
