    摘要: A molten metal purification device for purifying molten metal flowing through a flow body having a flow path formed by a pair of opposed side walls and a bottom wall. The device includes internal and external members provided inside and outside the flow body, respectively. The internal member includes an electrode body provided inside the path made of a conductive member and has a pair of opposed electrodes provided in the path where current flows across the electrodes through the molten metal and a non-conductive filter. The external member is configured as a magnetic field device having an upper surface side magnetized to an N or S pole and disposed below the flow body. Lines of magnetic force coming out from the N pole or entering the S pole intersect with the current to generate Lorentz force for driving the molten metal along a flowing direction in the path.

    摘要: An apparatus for dispersing particles within a molten material in a mold-less casting process comprises a primary electromagnet for generating an AC magnetic field and a secondary electromagnet adjacent to the primary electromagnet for generating an independent DC magnetic field. Each of the primary and secondary electromagnets comprises a coil and at least one of the electromagnets is positioned about a common longitudinal axis. A heat source may be positioned at a first end of the common longitudinal axis for forming a melt to be exposed to the AC and DC magnetic fields, and a particle injection device is positioned at one or more positions about the common longitudinal axis for injecting particles into the melt during magnetic field exposure. The apparatus does not include a solid body for containing the melt prior to solidification.

    摘要: A molding device includes a mold that forms a casting by cooling received melt, and a stirring unit that applies a magnetic field to the melt in the mold and allows a current to flow in the melt. The mold forms a vertical casting space that includes an inlet into which the melt flows and an outlet from which a product is taken. A transition plate is disposed at the mold space inlet. The melt can flow into the casting space from a hole in the transition plate. The stirring unit includes a magnetic field unit making lines of magnetic force vertically run into the casting space, and a first electrode at the inlet side and a second electrode at the outlet side that can flow current through the melt in the casting space, and generate an electromagnetic force by making the flowing current cross the lines of magnetic force.
