In metal casting, a tundish is a broad, open container with one or more holes in the bottom. It 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[2] and need to be removed, typically by mechanical means (scraping, cutting). Scrap recovered in this way is ordinarily reused in the steelmaking process.[3] A casting tundish is lined with refractory bricks specific to the liquid metal which is being cast.
