The tundish allows a reservoir of metal to feed the casting machine while ladles are switched, thus acting as a buffer of hot metal, as well as smoothing out flow, regulating metal feed to the moulds and cleaning the metal.

Metallic remains left inside a tundish are known as tundish skulls and need to be removed, typically by mechanical means (scraping, cutting)

Historically, a tundish was a flat funnel used to fill a tun, or barrel.

It is also mentioned by James Joyce in "Portrait of the Artist as a Young Man" as an Irish term for a funnel.
