Abstract
There is provided a device and a method for continuous casting of a homogeneous alloy consisting of immiscible metals. The device includes a crystallizer, fillable with a melt prepared from the metals, a homogenizer, a crystallizer, a feeder for passing a D.C. current through the melt in the crystallizer, in order to produce therein an electric field of predeterminable intensity. There is also provided an electromagnet adapted to produce therein a magnetic field of predeterminable induction, a nozzle adapted to direct jets of a coolant at selected regions of the crystallizer to cause the melt to solidify, and a puller to extract solidified portions of the alloy melt from the crystallizer. The electric field and the magnetic field are applied thereto so as to cross one another, and the interaction between the electric field produced by the D.C. current passing through the melt and the magnetic field produced by the electromagnet modify the effect of gravity, producing an indifferent equilibrium of the components of the alloy.
