A tundish is a wooden dish or shallow vessel with a tube at the bottom fitting into the bunghole of a tun or cask, forming a kind of funnel used in brewing.

In modern use, a tundish is a broad, open container with one or more holes in the bottom, used in various industrial processes. In metal casting, the tundish is used to feed molten metal into an ingot mould so as to avoid splashing and give a smoother flow.

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[1] and need to be removed, typically by mechanical means (scraping, cutting).

In plumbing, a tundish is a small funnel with a pipe discharging into it immediately above. It is used to provide an air break in overflows etc., preventing possible backwards contamination.[2]

Verteiler (Tundish)
Der Verteiler – ein metallurgisches Gefäss


Neben der ursprünglichen Aufgabe des Verteilers, das kontinuierliche Abgießen von Stahl im Strangguss zu gewährleisten, werden ihm zunehmend auch andere Aufgaben übertragen.

Diese Aufgaben reichen von der Abscheidung nichtmetallischer Einschlüsse über Strömungsberuhigung und Temperaturvergleichmässigung bis hin zur Hintanhaltung der Reoxidation des Stahls.
