Tundish

In the process of continuous casting, to transfer liquid steel from a steel teeming ladle to the mould, an intermediate vessel, called a tundish, is used. A tundishis a rectangular big end up refractory lined open container which may have a refractory lined cover on the top. The tundish bottom has one or more holes with slide gate(s) or stopper rod(s) for controlling the metal flow. It is used to feed liquid steel into the copper moulds of a continuous casting machine, so as to avoid splashing and give a smoother flow.

Due to the process layout, tundish refractory linings are designed to withstand thermal shock, prevent thermal loss, prevent oxidation, and resist erosion and corrosion.

Tundish can also be lined with Firebolts (refractory precasts) as shown in the model below.
