Abstract

The present invention provides increased recovery in additive-enhanced or alloy-enhanced molten steel. This is accomplished by deoxidizing powders blended with the additive alloys. The deoxidizing powder reacts with the oxygen, thereby depleting the oxygen in this region. The alloy or additive region is enriched, thereby improving the recovery in the molten steel.
