Abstract
An apparatus for continuous horizontal casting has a vessel for holding the molten metal to be cast. The vessel has an opening in its side which is arranged so that a stream of molten metal issuing therefrom enters a horizontal path. The stream is maintained in a molten state in the upstream end portion of the path and is cooled in an adjacent downstream portion of the path. A mechanism is provided for continuously drawing the strand formed from the stream of molten metal along the path. During the initial stages of solidification, the strand consists of a thin shell of solidified metal surrounding a molten core. The strand tends to sag here and an arrangement is provided for counteracting the weight of the strand. This arrangement includes a connected pair of electrical contacts one of which is immersed in the body of molten metal and the other of which contacts the strand. The arrangement further includes magnets which generate a horizontal magnetic field extending normal to the axis of the strand. The interaction of the magnetic field and the electrical current along the strand causes an upwardly directed force to be exerted on the strand. Another arrangement is provided for counteracting the metallostatic pressure due to the body of molten metal in the vessel. This arrangement includes coils which surround the path and are arranged to generate an alternating magnetic field around the strand.
