Apparatus for continuous vertical casting of metal strips, comprising: a mould ( 10 ) having top and bottom ends an open-ended mould cavity (C), a tundish ( 11 ) having a discharge opening ( 11 A) in direct communication with the mould cavity (C) to feed molten metal into a mould entrance opening (E) past an interface between the tundish ( 11 ) and the mould ( 10 ); a sealing device ( 14 ) forming a seal at said tundish-mould interface to prevent molten metal from entering said interface, and a device ( 12 ) for supplying molten metal to the tundish ( 11 ) and maintaining a level of molten metal therein. The scaling device ( 14 ) comprises a pair of flat horizontal surfaces ( 10 A, 11 B), one on the mould around the entrance opening (E) and one on the tundish ( 10 ) around the discharge opening ( 11 A), and a sealing element ( 14 A) formed of a sheet of graphite and being in constant sealing engagement with both said surfaces ( 10 A, 11 B). |
