Document Type and Number:
Japanese Patent JP2795841
Kind Code:
B2
Abstract:
An electromagnetic dam is employed to confine a vertically disposed pool of molten metal at the open end of the space between two counter-rotating, casting rolls in a continuous strip caster. The dam comprises three magnetic flux conductors each having a pair of spaced-part surfaces adjacent to and facing in the direction of the pool of molten metal. Two such surfaces of a first flux conductor define a relatively wide air gap adjacent the top part of the molten metal pool; two such surfaces of a second flux conductor define a relatively narrow air gap adjacent the bottom part of the pool, at the nip between the casting rolls; and two pool-facing surfaces of a third magnetic flux conductor are disposed between the spaced-apart surfaces of the first flux conductor in the wide air gap. Coils, for conducting a time-varying electric current, are associated with the three magnetic flux conductors to develop, at the air gaps, horizontal magnetic fields which confine the molten metal pool at the open end of the space between the casting rolls.
