ELECTRO-MAGNETIC NOZZLE DEVICE FOR CONTROLLING A STREAM OF LIQUID METAL TAPPED FROM A CRUCIBLE |
摘要 |
An electro-magnetic nozzle device for controlling the jet of liquid metal tapped at the outlet of a melting crucible comprises an electro-magnetic inductor and a magnetic field concentrator which surrounds the outlet of the crucible and is constituted by at least four three-dimensional sectors arranged evenly around the crucible outlet and separated from each other by radial slits, each sector having an internal water-cooled cavity, radially inner and outer walls of which the inner wall is of less height than the outer wall, and windings disposed in the inner and outer walls forming an electro-magnetic inductor.
