Abstract
The dissolved oxygen content in a bath of molten steel is controlled, in one embodiment, by diluting a slag layer atop the bath with an oxide such as lime (CaO), to reduce the percentage of MnO and FeO in the slag, and stirring the bath of molten steel. In another embodiment, a gaseous mixture of an inert gas and carbon monoxide is disequilibrium with the carbon and dissolved oxygen content is bubbled through the bath.
