  • Electromagnetic semi-continuous casting device and method having accurately matched and adjusted cooling process
    Patent number: 11179770
    Abstract: An electromagnetic semi-continuous device comprises a crystallizer frame, an internal sleeve, a primary cooling water cavity, a secondary cooling water cavity and a tertiary cooling water cavity. An electromagnetic semi-continuous casting method comprises the steps of (1) adjusting angles of the adjustable spherical nozzles; (2) inserting a dummy bar head in a bottom of the internal sleeve; (3) feeding cooling water to the primary cooling water cavity and the secondary cooling water cavity, then spraying the cooling water to form primary cooling water and secondary cooling water, and exerting a magnetic field on the internal sleeve; (4) pouring the melts into the internal sleeve, starting the dummy bar head, and beginning to perform continuous casting; and (5) spraying tertiary cooling water through the tertiary cooling water cavity, so that casting billets reduce temperature until the continuous casting is completed.
