Ladle

Abstract

Inert gas supply nozzle is mounted on a ladle body in such a manner its output-side end surface is inclined upward, relative to the bottom surface of a molten material passageway portion, in a direction toward a molten material discharge opening formed in the ladle body. Even when a portion of the molten material flows upward toward the nozzle's output-side end, that portion can be reliably prevented from entering the output-side end portion of the nozzle, by virtue of the inclined end surface. Thus, the inert gas supply nozzle can function to supply the inert gas into the molten material in a stable manner over a long period of time.

1 . A ladle for transferring molten material from a melting furnace to a molten material holding furnace attached to a casting machine, said ladle comprising: 
 a ladle body having a molten material discharge opening and a molten material passageway portion leading to said molten material discharge opening; and    an inert gas supply nozzle mounted on said ladle body adjacent said molten material discharge opening for emitting inert gas into the molten material,    wherein said inert gas supply nozzle has an output-side end surface inclined upward, relative to a bottom surface of said molten material passageway portion, in a direction toward said molten material discharge opening.
