Abstract
Treatment of molten steel in a ladle, which comprises blowing inert gas into the ladle from its bottom, partially immersing a receptacle which covers the portion of the molten steel where the inert gas bubbles out and maintain non-oxidizing atmospheres within the receptacle with the gas so as to prevent oxidation of the molten steel by the slag.
