  • System and method for continuous casting of molten material
    Patent number: 10926321
    Abstract: An apparatus for continuous casting of molten material includes an elongate tube of electrically conductive material having an inner and an outer wall defining a molding cavity therein, the inner and outer walls having a first end having an inlet for receiving the molten material and a second end having an outlet for removing a solidifying billet formed from the molten material; an electrical coil with inner and outer surfaces, the electrical coil arranged to surround the outer wall of the elongate tube; and an annular channel defined by the outer wall of the elongate tube and the inner surface of the electrical coil. When pulsating current passes through the electrical coil, a counter current is induced in the elongate mold causing a repelling force between the electrical coil and the elongate mold, thereby causing inward radial flexure of the elongate mold.
