Abstract (en)

A method of casting is provided in which molten material is fed from a source of molten material, such as a ladle, to a vessel, the vessel feeding molten material to a casting location. The molten material is fed to the casting location substantially continuously during casting, but the molten material is fed from the source to the vessel for only a part of the time of casting, for instance, less than 75%. It is a preferred feature that the volume of molten material in the vessel can be varied, but that the head of molten material over the outlet passage from the vessel is substantially constant. A tilting tundish to achieve this aim is provided. The invention provides advantages in terms of the flexibility of timing of molten metal delivery to the casting system. <IMAGE>
