ABSTRACT:
Disclosed is an electromagnetic continuous casting apparatus for a material having a low electric conductivity. The casting apparatus includes a crucible having a vertical axis. The crucible comprises an upper hot crucible and a lower cold crucible. The crucible is surrounded with an induction coil. The hot crucible is formed of a non-metallic material having a high electric conductivity and is not water-cooled. The cold crucible has a cooling structure and is formed of a metallic material having a high thermal conductivity and a high electric conductivity.
