Abstract
A continuous casting device includes a mould, a nozzle, and an electromagnetic stirrer provided around the nozzle above the mould, the stirrer including a core of a magnetic material that extends circumferentially around the nozzle and a plurality of windings wound around the core. The windings are wound around a cross section of the core as seen in the circumferential direction of the core.
Claims14
A continuous casting device comprising
- a mold,
- a nozzle, and
- an electromagnetic stirrer provided around the nozzle above the mold, said stirrer comprising a core of a magnetic material that extends circumferentially around the nozzle and a plurality of windings wound around said core, characterized in that said core comprises a portion having an essentially toroid shape and that said windings are wound around the portion in an essentially poloidal direction.
A continuous casting process for the casting of a metal, in which a metal is supplied through a tubular nozzle to a mold, and in which the metal flowing through the tubular nozzle is stirred by application of an electromagnetic field thereto, said electromagnetic field being generated by means of a stirrer comprising a core of a magnetic material that extends circumferentially around the nozzle and a plurality of windings wound around said core, characterized in that said core comprises a portion having an essentially toroid shape and that said windings are wound around the portion in an essentially poloidal direction.
