  • Two-segment electromagnet semi-solid diecasting apparatus and diecasting method using same
    Patent number: 11931798
    Abstract: Disclosure provides a two-segment electromagnet stirring member, and a two-segment electromagnet semi-solid die-casting apparatus including the same, and a die-casting method using the same. The two-segment electromagnet stirring member includes a plurality of magnetic field generation parts therein, and includes a first electromagnetic stirring part and a second electromagnetic stirring part separated from each other. The first electromagnetic stirring part and the second electromagnetic stirring part are coupled to each other in a ring shape to surround an outer circumferential surface of a sleeve to perform electromagnetic stirring to molten metal in the sleeve, and are coupled to each other so as to position the plurality of magnetic field generation parts at radially equal gaps around the sleeve.
    Type: Grant
