Method and apparatus for removal of gaseous, liquid and particulate contaminants from molten metals

Patent ·
OSTI ID:5636054

This patent describes a device for removing contaminants from a molten metal composition. The contaminants are characterized as having less electrical conductivity than the molten metal, comprising a body of toroidal configuration having an outer wall and a toroidal cavity. The toroidal body having inlet and outlet ends adapted to receive and discharge a stream of the molten metal composition and means for applying a magnetic field to the molten metal composition within the toroidal cavity which magnetic field simultaneously induces an electric current which flows perpendicular to the magnetic field so as to impose a force on the molten metal composition at right angles to a plane containing the magnetic field and current flow direction.
