摘要：
A refractory article is provided for the prevention of vortexing in molten metal as it is drained through a nozzle in a metallurgical vessel. The article has at least on rib extending substantially radially outwardly from an opening therein for draining of molten metal from the vessel, said rib protruding upwardly from an inner surface of the article so as to prevent the formation of rotating boundary layer flow within the molten metal.
