ABSTRACT:
The present invention relates to a metallurgical ladle and more particularly to the bottom of the ladle having an outlet through which the molten metal can drain. An object of the present invention is to increase the efficiency of a ladle draining operation, including reducing the amount of discarded metal, avoiding the premature flow of slag through the outlet, and reducing the contamination of slag in the molten metal effluent. The ladle bottom comprises a plurality of terraces and flow channels, ultimately directing the stream of molten metal to an outlet of the ladle. The terraces are described as capturing slag and the channels permit molten metal to flow preferentially through the outlet.
