  • Process for electromagnetically casting or reforming strip materials
    Patent number: 4419177
    Abstract: A process for electromagnetically containing and forming molten material into a desired thin strip shape. At least two inductors are employed which are powered at respectively different frequencies. The frequency of the current applied to the upstream inductor is substantially lower than the frequency applied to the downstream inductor thereby providing improved efficiency and reduced power consumption.
