Abstract (en)
[origin: EP0737531A1] An electromagnetic confining apparatus (30) prevents the escape of molten metal (38) through the open end (36) of a vertically extending gap (35) between two horizontally extending members (31,32), such as two counter-rotating rolls of a continuous strip caster. The molten metal (38) is located between the two members. The apparatus includes a vertically disposed coil (40) through which flows a time-varying electric current to generate a first horizontal magnetic field adjacent the open end of the gap. A time-varying conduction current is directed through the pool of molten metal adjacent the open end of the gap (35), in a vertical direction opposite that of the current flow in the adjacent portion of the coil. The flow of conduction current through the molten metal pool generates a second horizontal magnetic field adjacent the open end of the gap (35) and which augments the first horizontal magnetic field to provide a repulsive body pressure which urges the pool of molten metal inwardly away from the open end of the gap (35). <IMAGE>
