This invention is directed to a system for reducing the yield loss from a metallurgical vessel, such as a ladle holding liquid metal having a slag layer thereon, by delaying the onset of slag entrapment in the metal stream during the tapping thereof. More particularly, such system includes a modification to the drain hole and/or bottom of such vessel.
